Lapho onjiniyela nabaphathi bokuthenga baklama inethiwekhi yokulethwa kwamanzi okuphuzwayo, ukukhethwa kwe-camlock fittings kuvame ukunquma ukuphepha kwesikhathi eside, ukuthembeka, kanye nokusebenza kahle kwesistimu yonke. Into esetshenziswayo kula ma-quick-connect couplings akumelwe nje ukumelana nengcindezi yemishini kodwa futhi kufanele ihlale ingasebenzi ngamakhemikhali ukuze kungabibikho izinto eziyingozi ezingena emanzini abantu abawaphuza nsuku zonke. Ezimbili zezinketho ezivame kakhulu emakethe namuhla i-food-grade brass, ekhiqizwa njenge-lead-free copper-zinc alloy, kanye ne-6061 aluminium ephathwe nge-hard-anodized coating ukuze kuthuthukiswe ukuvikelwa kwendawo engaphezulu. Into ngayinye iletha isethi ehlukile yezakhiwo zemishini, ezokushisa, kanye nokumelana nokugqwala okwenza ifanele izinhlelo ezithile, futhi ukuqonda lokhu kwehluka kubalulekile ukuze wenze isinqumo sokuthenga esinolwazi. E-Varicpand International, sihlinzeka ngazo zombili lezi zinhlobo ngobunjiniyela obunembile nokulandeleka okugcwele, siqinisekisa ukuthi ingqalasizinda yakho yamanzi okuphuzwayo ihlangabezana namazinga aphezulu kakhulu embonini. Lokhu kuqhathanisa okuphelele kuhlola zombili izinto ngokwezindinganiso zokuphepha, ukuziphatha kwemishini, ukusebenza kokushisa, ukumelana nokugqwala, umthelela wekhwalithi yamanzi, ubude besikhathi sokusebenza, kanye nokusimama ukuze ukwazi ukukhetha ngokuzethemba i-camlock coupling efanele yephrojekthi yakho.

Ama-camlocks e-brashi ezingeni lokudla abe yinto ethembekile ezinhlelweni zokuhambisa amanzi amashumi eminyaka ngenxa yekhono lawo elihle lokwenziwa, izakhiwo zemvelo zokulwa namagciwane, kanye nokumelana nokugqwala okufakazelwe emanzini ane-pH engathathi hlangothi. Ngakolunye uhlangothi, i-6061 aluminium enongqimba olunzima lwe-hard-anodized inikeza amandla ahlanganiswe nesisindo okwehlula, ukumelana nokugqwala okuphezulu ezindaweni ezinamakhemikhali anolaka, kanye nesisindo esincane esinciphisa ukukhathala kokuphatha ezinhlelweni eziphathwayo. Isinqumo phakathi kwalezi zinto ezimbili akulula, ngoba sincike ezintweni ezinjengezinga lokushisa lokusebenza, ukuchayeka emanzini ane-chlorine, imvamisa yokuhlanganisa nokuhlukanisa, kanye nohlaka oluthile lwezimithetho olulawula indawo yakho. Ngokuhlola idatha yezobuchwepheshe eceleni, lo mhlahlandlela ukunika amandla ukuthi uhlole ukuthi iyiphi into ehambisana nezidingo zakho zokusebenza kanye nezibopho zemithetho. Siphinde sigqamise ukuthi amandla okukhiqiza e-Varicpand International kanye nezinhlelo zokuqinisekisa ikhwalithi zisekela kokubili ukukhethwa kwezinto, ziqinisekisa ukuthi yonke i-fitting iletha ukusebenza okungaguquki nokusebenza okungavuziyo ezimweni zangempela zomhlaba.

Ukwakheka kwamakhemikhali ethusi elisezingeni lokudla kwehluke kakhulu kulelo thusi elijwayelekile, ngoba lakhiwe ngaphandle komthofu ukuze lihambisane nemithetho eqinile yamanzi okuphuza. Ama-alloys ajwayelekile ethusi elisezingeni lokudla, njenge-C87850 noma i-C46500, ahlanganisa ithusi ne-zinc kanye nokwengezwa okuncane kwe-tin, bismuth, noma i-silicon, okuthatha indawo yomthofu ukuze kugcinwe ukusebenza kahle kokusika kuyilapho kuqedwa ubungozi bokungcola ngezinsimbi ezisindayo. La ma-alloys angenamthofu aklanyelwe ukuhlangabezana nezidingo zokukhishwa kwe-NSF/ANSI 61, ebeka amazinga aphezulu avumelekile omthofu nokunye ukungcola emanzini athintana nokufakwayo. Ngokuphambene, i-6061 aluminium i-alloy eqiniswa ngemvula equkethe i-magnesium ne-silicon njengezinto zayo eziyinhloko zokuhlanganisa, futhi uma ibhekana ne-hard anodizing, ungqimba lwe-aluminium oxide (Al₂O₃) lwakhiwa phezu kwendawo ngenqubo ye-electrochemical. Lolu ngqimba lwe-anodized luminyene, luqine kakhulu, futhi luzinzile ngamakhemikhali, lwakha umgoqo ovimbela ukuthintana okuqondile phakathi kwe-aluminium substrate namanzi, ngaleyo ndlela kuncishiswe amathuba okuthi izinsimbi zingene emanzini okuphuza.

Ngokombono wokuthobela imithetho, kokubili lezi zinto zingakhiqizwa ukuze zihlangabezane nezidingo ze-NSF/ANSI 61, imithetho ye-FDA yokuthintana nokudla, kanye ne-California Proposition 65, inqobo nje uma inqubo yokukhiqiza ilawulwa ngokucophelela futhi iqinisekiswe. Ama-camlocks ethusi asebenzisa izinto eziqinisekisiwe ezingenawo umthofu futhi enza ukuhlanza nokuvikela okufanele azophumelela ekuhlolweni kokukhishwa komthofu, ithusi, ne-zinc, kuyilapho i-aluminium eqinile ene-anodized kumele ibonise ukuthi ukumbozwa akunayo imifantu futhi akukho i-hexavalent chromium noma ezinye izinto eziyingozi ezethulwa ngesikhathi sokugezwa kwe-anodizing. I-Varicpand International inezinhlelo zokuqinisekisa ikhwalithi ezibhalwe phansi futhi isebenza nabahlinzeki bezinto eziqinisekisiwe, ngakho wonke ama-brass camlock coupling nama-aluminium camlock coupling esiwakhiqizayo anokulandeleka okugcwele kwezinto kusukela esitifiketini sokuqala sase-mill. Ukuhlola kwethu kwangaphakathi kuhlanganisa ukuhlola ubukhulu, ukuhlola ukucindezela, nokuhlola ikhwalithi yendawo engaphezulu, futhi sigcina izitifiketi ezingabuyekezwa abahloli nabasebenzisi bokugcina ngaphambi kokugunyaza umkhiqizo ukuze ufakwe ezinhlelweni zamanzi okuphuza zomasipala, ezolimo, noma ezimbonini. Lokhu kuzibophezela ekuqineni kwezinto kunikeza amakhasimende ethu ukuzethemba kokuthi ama-fittings abo azosebenza njengoba kucacisiwe kokubili ngaphansi kwenkonzo evamile nasezimeni ezinzima.

Izici zokusebenza kwemishini yokuxhuma kwe-camlock zibonisa ukuthi ingcindezi engakanani nokulimala ngokomzimba engakubekezelela ngesikhathi sokusebenza, futhi umehluko phakathi kwe-brass yezinga lokudla ne-6061 i-aluminium eqinile ene-anodized mkhulu kodwa uyahlangana. Ama-alloys e-brass asetshenziselwa ukuxhuma kwamanzi ngokuvamile abonisa i-elastic modulus ebangeni eliphakathi kuka-100 no-120 GPa, kuyilapho i-6061 aluminium inikeza i-elastic modulus ecishe ibe ngu-68.9 GPa, okusho ukuthi ingxenye ye-aluminium ivumelana kakhulu uma kukhulunywa ngobukhulu bodonga oluthile. Mayelana namandla okudonsa, i-6061-T6 aluminium elashwe ngokushisa ifinyelela amandla okugcina okudonsa acishe abe ngu-310 MPa namandla okuvumela acishe abe ngu-276 MPa, kuyilapho i-brass engenawo umthofu ngokuvamile ifinyelela amandla okugcina okudonsa aphakathi kuka-380 no-450 MPa namandla okuvumela aphakathi kuka-200 no-280 MPa. Ukunwebeka lapho kephuka kungenye indlela ebalulekile yokulinganisa, njengoba i-brass ivamise ukubonisa ukunwebeka okungu-15% kuya ku-35%, okwenza ibe nokuvumelana okukhulu futhi imelane nokuqhekeka lapho ishaywa, kuyilapho i-6061-T6 aluminium ibonisa ukunwebeka okucishe kube ngu-12% kuya ku-17%. I-shear modulus ye-brass icishe ibe ngu-37 GPa uma iqhathaniswa no-26 GPa we-aluminium, futhi amandla e-shear alandela iphethini efanayo, okuthinta indlela ukuxhuma okubhekana ngayo nemithwalo yokujikeleza ngesikhathi sokuqinisa nokukhulula okuphindaphindiwe kwezingalo ze-cam. Ngaphezu kwalokho, ubulukhuni bengaphezulu le-aluminium ene-anodized bungafinyelela ku-350 kuya ku-500 Vickers, kudlula kakhulu ubulukhuni be-Brinell be-brass, okunikeza ukuxhuma okune-anodized amandla angaphezulu okumelana nokuklwebheka, ukugqwala, nokugqokwa okubangelwa isihlabathi nezinsalela ezivame ukutholakala emanzini emvelo.

Ukusebenza kokushisa kubalulekile ngokufanayo, ikakhulukazi ezinhlelweni eziphethe amanzi ashisayo noma ezibhekana nokushintshashintsha okusheshayo kwezinga lokushisa, futhi lapha lezi zinto ezimbili zihluka kakhulu. Iphuzu lokuncibilika lethusi licishe libe ngu-900°C kuya ku-940°C kuye ngokuthi i-alloy eqondile, kuyilapho i-6061 aluminium incibilika cishe ku-582°C kuya ku-652°C, okusho ukuthi ithusi lingakwazi ukumelana namazinga okushisa aphezulu ngaphambi kwanoma yibuphi ubungozi bokuthamba noma ukuhlanekezela. Ukuqhutshwa kokushisa kuphakeme kakhulu nge-aluminium, njengoba i-6061 inikeza cishe u-167 W/m-K uma kuqhathaniswa nethusi elingaba ngu-120 W/m-K, ngakho ama-camlocks e-aluminium ashabalalisa ukushisa ngokushesha emanzini ashisayo futhi mancane amathuba okuthi adale izindawo ezishisayo ezindaweni zokuxhuma. Nokho, i-coefficient yokwanda kokushisa ye-aluminium icishe ibe ngu-23.5 µm/m-K, ephakeme kunethusi elingaba ngu-19 kuya ku-20 µm/m-K, okusho ukuthi izinsimbi ze-aluminium ziyokwanda futhi zinciphe kakhulu ngokushintsha kwezinga lokushisa, okungenzeka kuthinte ukuqina kokuvala uma ukushintshashintsha kokushisa kunzima. Ungqimba lwe-hard-anodized ngokwalo lunokumelana okuhle kakhulu nokushaqeka kokushisa ngoba ungqimba olufana ne-ceramic oxide luboshelwe ngokuqinile ku-aluminium substrate, kodwa abaklami kumele bacabangele ukwanda okuhlukile phakathi komzimba wokuxhuma nanoma yimaphi ama-rubber gaskets asetshenziswayo ekuvaleni. Ngokusebenza okuqhubekayo, ithusi lezinga lokudla ngokuvamile lingasebenza emazingeni okushisa afinyelela ku-200°C, kuyilapho umkhawulo osebenzayo we-hard-anodized aluminium emanzini uvamise ukuba ngu-150°C kuya ku-175°C, ngakho noma iyiphi into kulezi ezimbili izobamba kalula amazinga okushisa ajwayelekile okuphuza amanzi afinyelela ku-60°C kuya ku-80°C atholakala ezindaweni eziningi zasekhaya nezohwebo.

Ukumelana nokugqwala kuyinto ebaluleke kakhulu ukuze isistimu yamanzi okuphuza isebenze isikhathi eside, ngoba noma ukucekelwa phansi okuncane kokuxhunywa kungakhipha izinhlayiya zensimbi emanzini futhi kukhubaze ukuphepha nokunambitheka. Ithusi ngokwemvelo liyamelana nokugqwala emanzini ane-pH phakathi kuka-6 no-8, okuhlanganisa iningi lamanzi okuphuza kamasipala, kodwa lisengozini yokwehluleka okuthile okubizwa ngokuthi i-dezincification lapho i-zinc ikhishwa ngokukhethekile, kushiywe isakhiwo sethusi esinezimbotshana esenza ukuxhunywa kube buthakathaka. Ukulungisa lokhu, ukuxhunywa kwethusi lamanzi kuvame ukwenziwa kusetshenziswa ama-alloys amelana nokukhishwa kwe-zinc (DZR) noma ngokungeza izivimbeli, futhi ukuqinisekiswa kwe-NSF/ANSI 61 kuhlanganisa ukuhlolwa okuqinisekisa ukuthi i-alloy imelana nokugqwala ngaphansi kwezimo ezigxilile. I-chlorine, evame ukusetshenziswa njengesibulala-magciwane ezinhlelweni zikazwelonke zamanzi, ingasheshisa ukugqwala kuzo zombili izinto, kodwa ithusi ngokuvamile lisebenza kahle ekugxiliseni kwe-chlorine okufika kuma-mg/L ambalwa inqobo nje uma amakhemikhali amanzi ezinzile. I-aluminium eqinisiwe (hard-anodized) inikeza ukuvikelwa okuhle kakhulu ekugqwaleni naseku-oxidization ngoba ungqimba lwe-Al₂O₃ alunamandla kakhulu futhi lunamathela ngokuqinile ensimbi eyisisekelo, okwenza lumelane nokuhlaselwa ama-chlorides, ama-asidi athambile, ngisho namanzi olwandle.

Ngokombono wokuphepha kokudla, umbuzo obalulekile ukuthi ngabe into ikhipha izinto eziyingozi emanzini, futhi zombili izinketho zingaklanywa ukuze ziphephe ngemikhuba efanele yokukhiqiza. Ithusi elingenawo umthofu lisusa ukungcola okudume kakhulu okuhlotshaniswa namafithingi endabuko ethusi, futhi ithusi ne-zinc ezikhiphayo ngamanani amancane kakhulu zilawulwa yi-NSF/ANSI 61 ukuze zihlale zingaphansi kwamazinga ayingozi. Ukumbozwa okuqinile kwe-hard-anodized ku-aluminium engu-6061 kusebenza njengesithiyo esivimbela ukuthintana okuqondile kwensimbi namanzi, futhi ngenxa yokuthi ungqimba lwe-anodized luhlangene ngokuphelele nomoya-mpilo, alukhipheki ngamakhemikhali emanzini; nokho, kubalulekile ukuthi lokhu kumbozwa kuvalwe kahle ngesikhathi sokukhiqiza ukuze kuvalwe izimbotshana ezincane ezenzeka ngokwemvelo ngesikhathi sokwenziwa kwe-anodizing. Ukukhula kwamagciwane nokwakheka kwe-biofilm ezingxenyeni ezingaphezulu nakho kuyinkinga ezinhlelweni zamanzi okuphuza, futhi kokubili ithusi ne-aluminium ene-anodized zinikeza indawo ebushelelezi ephikisana nokunamathela kwamagciwane uma kuqhathaniswa namapulasitiki arhabaxa noma izinsimbi ezingelashwa. Ithusi linenzuzo eyengeziwe yezakhiwo zemvelo zokulwa namagciwane ezibangelwa ama-ion ethusi, okunganciphisa ukuphila kwamagciwane athile ezingxenyeni ezingaphezulu, kuyilapho ungqimba lwe-anodized oluminyene, olungenazimbotshana kulula ukuluhlanza futhi alugcini izinto eziphilayo. Zombili lezi zinto zingathola isitifiketi se-NSF/ANSI 61 kanye ne-California Proposition 65, futhi i-Varicpand International iqinisekisa ukuthi amafithingi ethu aqediwe ahlanzwa, omiswa, futhi apakishwa ukuze kuvinjelwe ukungcola ngaphambi kokuthumela esikhungweni sakho.

Iphilisi yesevisi elindelekile ye-camlock coupling ohlelweni lwamanzi okuphuza incike kumakhemikhali amanzi, izingcindezi zokusebenza, kanye nokuthi i-fitting ixhunywa futhi inqanyulwe kangaki, kodwa kokubili i-brass yezinga lokudla kanye ne-aluminium engu-6061 e-hard-anodized inganikeza ukusebenza okuthembekile kweminyaka eminingi uma icaciswe kahle. Ama-brass fittings aziwa ngokuqina kwawo ekufakweni okuhlala njalo noma okungahlala njalo lapho engavamile ukuphazanyiswa, futhi ayathethelela kakhulu ukungahambisani okuncane kanye nokuqiniswa ngokweqile kancane kwe-cam arms ngenxa yokuthambeka kwawo. I-aluminium e-hard-anodized, enobuso obulukhuni kakhulu, igqama ekusetshenzisweni okubandakanya ukuxhunywa nokunqanyulwa njalo, njengemigqa yokudlulisa amanzi yesikhashana ezindaweni zokwakha, ukunisela kwezolimo, noma imisebenzi yokusabela okuphuthumayo, ngoba i-coating imelana nemihuzuko nokugqoka okungagcina kuveze indawo ye-aluminium engalashwa. Izidingo zokunakekela zincane kuzo zombili izinto, kodwa i-brass ingashintsha umbala ngokuhamba kwesikhathi futhi idinge ukuhlanjululwa ngezinto ezithambile ukuze igcine ukubukeka kwayo, kuyilapho i-aluminium e-anodized ingadingi ukunakekelwa kwangaphezulu futhi ingasulwa ngendwangu emanzi. Ukugqoka okungokomshini okuvela ekusebenzeni okuphindaphindiwe kwe-cam arm kumelwa kangcono indawo e-anodized, enciphisa ubungozi be-galling nokubamba kwentambo okungahlupha ama-aluminium alloys athambile, futhi i-Varicpand International iklama ama-cam arms ethu ngamaphrofayili acutshungulwe ngokunembile ukuze kuqinisekiswe ukubambana okungaguquki nokusebenza okungavuziyo ezinkulungwaneni zemijikelezo.

Ngokombono wezemvelo, ukusimama kuya kuba yisici esinqumayo ekukhetheni izinto zokwakha kumaphrojekthi engqalasizinda, futhi zombili lezi zinto zinikeza izinketho ezinhle zokuphela kokuphila kwazo. Ikhabhoni ehlanganiswe ku-aluminium icishe ibe ngu-8 kuya ku-12 kg CO₂ ngekhilogremu yento uma ikhiqizwa emithonjeni eyinhloko, kodwa lokhu kwehla kakhulu kufinyelele cishe ku-1 kuya ku-2 kg CO₂ ngekhilogremu uma kusetshenziswa i-aluminium egaywe kabusha, futhi i-aluminium ingagaywa kabusha ngokungenamkhawulo ngaphandle kokulahlekelwa ikhwalithi. Ithusi, njengengxubevange esekelwe kukhopha, linezinga eliphezulu lekhabhoni ehlanganisiwe elilinganiselwa ku-5 kuya ku-7 kg CO₂ ngekhilogremu ekukhiqizweni okuyinhloko, kodwa ithusi ne-zinc nakho kungagaywa kabusha kakhulu, futhi ithusi eligaywe kabusha ligcina izakhiwo zalo zemishini ezinkathini eziningi zokuphila. Amandla ahlanganisiwe adingekayo ukukhiqiza i-aluminium makhulu ngenxa yenqubo yokuncibilikisa ngogesi, kanti ukukhiqiza ithusi kuncane kancane ekusebenziseni amandla, kodwa ubuncane besisindo se-aluminium bushoyo ukuthi amandla okuthutha ayancipha empilweni yomkhiqizo. Ukufakwa kwe-hard anodizing kwengeza inani elincane lamandla namakhemikhali ngesikhathi sokukhiqiza, kodwa kukhulisa kakhulu isikhathi sokusebenza sokuqina kwento, okuwumphumela omuhle kumthelela wonke wezemvelo ngonyaka ngamunye wokusebenza. I-Varicpand International izibophezele ezenzweni zokukhiqiza ezisimeme, okuhlanganisa ukuhlukaniswa kwezinsimbi ezilahliwe, ukusebenza kwemishini okonga amandla, nokupakisha okunesibopho, futhi sikhuthaza amakhasimende ukuthi acacise izinto ezinokuqukethwe okugaywe kabusha lapho izidingo zephrojekthi zivumela.

Ngaphezu kokuqhathanisa okwezinga, onjiniyela bazuza ezilinganisweni zobuningi eziqhathanisa ngokuqondile ukusebenza kwesakhiwo sethusi ne-aluminium eqinile (hard-anodized) ezakhiweni ezijwayelekile ze-camlock. Isilinganiso samandla nesisindo siyipharamitha ebalulekile ezinhlelweni eziphathwayo, futhi lapha i-aluminium inenzuzo ecacile: i-6061-T6 inamandla okudonsa acishe abe ngu-310 MPa nokuminyana kwayo okungu-2.70 g/cm³, okunikeza isilinganiso esicishe sibe ngu-115 kN·m/kg, kuyilapho ithusi elingenawo umthofu (lead-free brass) ngamandla angu-450 MPa nokuminyana okungu-8.50 g/cm³ linikeza kuphela cishe u-53 kN·m/kg. Lokhu kusho ukuthi ngenani elifanayo lokuthwala umthwalo, i-camlock ye-aluminium ingenziwa ibe lula kakhulu, okuyinto enqumayo lapho abasebenzi kumele baphathe amahose nama-fittings kaningi usuku lonke. Isilinganiso sokuqina nesisindo sikhuluma indaba efanayo, nge-elastic modulus ye-aluminium engu-68.9 GPa ihlukaniswe nokuminyana kwayo inikeza cishe u-25.5 GPa·cm³/g, uma kuqhathaniswa nethusi elingaba ngu-12.9 GPa·cm³/g, okuqinisekisa ukuthi i-aluminium isebenza kahle kakhulu ezinhlelweni zokugoba lapho isisindo sikhawulelwe. Ukusakazeka kokushisa (thermal diffusivity), okukala ukuthi into iqhubisa ukushisa ngokushesha kangakanani uma kuqhathaniswa namandla ayo okugcina ukushisa, kucishe kube ngu-68 mm²/s ku-6061 aluminium uma kuqhathaniswa no-34 mm²/s wethusi, okusho ukuthi i-aluminium ilinganisa izinguquko zokushisa ngokushesha futhi ayithambekele kangako ekucindezelekeni kokushisa kwendawo ethile. Ukuqina nokuphila (resilience and toughness), okuchaza ikhono lento yokumunca amandla ngaphandle kokuguquka unomphela nokumelana nokuphuka, ngokuvamile kungcono ethusini ngenxa yokunwebeka kwalo okuphezulu, okwenza ithusi libe ukukhetha okuthethelelayo ezinhlelweni lapho kungenzeka khona ukushayisana noma ukudlidliza.

Lapho usebenzisa lezi zibalo ekukhetheni kwe-camlock yangempela emhlabeni, umongo wokusetshenziswa ekugcineni unquma ukuthi iyiphi into ekhethwa kahle kwezobunjiniyela. Kokuxhumeka okungaguquki, okuhlala njalo esikhungweni sokuhlanza amanzi sikamasipala lapho isisindo singabalulekile futhi amanzi ashisayo emazingeni okushisa aphakeme engahlangabezana nawo, i-brass yezinga lokudla ivame ukukhethwa ngenxa yokumelana kwayo nokushisa okuphezulu, ukuqina, kanye nomlando oqinisekisiwe. Ohlelweni lokuletha amanzi oluhambayo olusetshenziswa kwezolimo, ukusiza ezinhlekeleleni, noma ukucubungula ukudla oludinga ukuphathwa njalo, ukuthuthwa, nokuxhunywa emithonjeni ehlukahlukene yamanzi, ubuncane besisindo kanye nokumelana nokugqwala kwe-aluminium eqinisiwe (hard-anodized aluminum) kunikeza izinzuzo zokusebenza ezidlula izinga layo eliphansi kancane lokushisa. Umehluko wezindleko nawo ubalulekile, njengoba i-brass eluhlaza ivamise ukubiza kakhulu ngekhilogremu ngayinye kune-aluminium, nakuba intengo yokugcina incike ebunkimbinkimbeni bokwenza kanye nezidingo zokuqeda kwesixhumi ngasinye. I-Varicpand International inikeza kokubili i-brass camlock coupling kanye ne-aluminium camlock coupling enosekelo lwezobunjiniyela olwenziwe ngokwezifiso, ngakho ithimba lethu lingakusiza ukwenza izibalo ezinembile ezidingekayo ngezidingo zakho ezithile zokucindezela, izinga lokushisa, kanye nomjikelezo wokusebenza.

Ngokusekelwe ekuhlaziyweni okuphelele ngenhla, singanikeza umhlahlandlela ocacile wokuthi kufanele ukhethe luphi uhlobo ngalunye lwe-camlock ohlelweni lwakho lokulethwa kwamanzi okuphuzwayo. Ama-camlock ethusi ezinga lokudla ayikhetho elifanele kakhulu ezikhungweni ezihlala njalo, izinhlelo zamanzi ashisayo, nezinhlelo lapho i-fitting izohlala ixhunyiwe isikhathi eside, njengokuxhunywa kwamapayipi angaguquki emakhishini ezentengiselwano, ezibhedlela, nezikhungo zokuhlanza amanzi. Ithusi futhi liyinketho engcono lapho amanzi ene-asidi kancane, ngoba ama-DZR brass formulations anikeza ukumelana okukhethekile namakhemikhali amanzi anolaka, nalapho okubalulekile khona ukuqina kwesikhathi eside nokumelana nomthelela endaweni yezimboni enzima.

Ukuze ufunde kabanzi ngamagugu enkampani yethu, izitifiketi, kanye nefilosofi yokukhiqiza, siyakumema ukuthi uvakashele ku-Ngathi ikhasi, lapho uzothola khona imininingwane mayelana nokuzibophezela kwethu kwekhwalithi, ukusimama, nobambiswano namakhasimende.

Ukukhetha phakathi kwe-brass yezinga lokudla ne-aluminium ye-6061 hard-anodized kuma-camlock fittings ezinhlelweni zokulethwa kwamanzi okuphuza kudinga ukuhlolwa ngokucophelela kwamandla emishini, ukuziphatha kokushisa, ukumelana nokugqwala, ukuthobela imithetho, kanye nezindleko zomjikelezo wokuphila, futhi akukho nanye kulezi zinto ezimbili ezingcono kunenye ngokuphelele. I-brass yezinga lokudla inikeza ukunwebeka okuthuthukile, ukubekezelela izinga lokushisa eliphezulu, izakhiwo zemvelo zokulwa namagciwane, kanye nomlando wamakhulu eminyaka emsebenzini wamanzi okuphuza, okuyenza ibe ukukhetha okulondolozayo kokufakwa unomphela namanzi ashisayo. I-6061 hard-anodized aluminium inikeza amandla angenakuqhathaniswa uma kuqhathaniswa nesisindo, ukumelana nokugqwala okukhethekile kumakhemikhali ayinselele, kanye nobuso obulukhuni kangangokuthi bumelana nokugqokwa ekuphindweni okungenakubalwa kokuxhuma, okuyenza ilungele izinhlelo eziphathwayo nezilula. Zombili lezi zinto zingakhiqizwa ukuze zihlangabezane nezidingo eziqinile ze-NSF/ANSI 61, FDA, kanye ne-Proposition 65, futhi zombili zingavuselelwa ngokugcwele, zisekela ukuthuthukiswa kwengqalasizinda eqhubekayo. E-Varicpand International, siyaqonda ukuthi yonke iphrojekthi inezidingo ezihlukile, yingakho sikhiqiza zombili lezi zinketho ngobunjiniyela obunembile obufanayo, ukuhlolwa kwekhwalithi okuqinile, nokuzibophezela ekusebenzeni okungavuziyo okusenze saba uzakwethu othembekile embonini. Noma ngabe uthuthukisa indawo yamanzi kamasipala, uhlomisa indawo yokucubungula ukudla, noma usabalalisa izinhlelo zamanzi eziphuthumayo, ithimba lethu lingakuqondisa esixazululweni esifanele futhi likulethe ama-fittings asebenza ngokuthembekile amashumi eminyaka. Xhumana ne-Varicpand International namuhla ukuze uxoxe ngezidingo zakho, ucele amasampula, noma uthole isilinganiso sobunjiniyela esinemininingwane yephrojekthi yakho elandelayo yamanzi okuphuza.

Umehluko oyinhloko usekukhetheni kwempahla eyisisekelo nokwelashwa kwendawo engaphezulu. I-brass yezinga lokudla i-alloy yethusi ne-zinc engenawo umthofu enikeza ukunwebeka okuhle kakhulu, ukumelana nokushisa okuphezulu kufinyelela ku-200°C, kanye nezakhiwo zemvelo zokulwa namagciwane. I-aluminium ye-6061 ene-hard-anodized inesisindo esilula kakhulu, indawo engaphezulu elukhuni efana ne-ceramic ye-aluminium oxide emelana nokuklwebheka nokugqwala, kanye nezinga eliphansi lokusebenza eliphezulu elizungeze i-150-175°C, okwenza kube kufaneleka kangcono ezinhlelweni eziphathwayo lapho isisindo nokumelana nokugqwala kuyizinto ezibalulekile.

Yebo, i-6061 hard-anodized aluminium iphephile emanzini aphuzekayo uma ukugoqwa kwe-anodized kwenziwe kahle futhi kuvalwe. Ungqimba lwe-hard-anodized luwumgoqo omncane, ozinzile ngamakhemikhali we-aluminium oxide ovimbela ukuthintana okuqondile phakathi kwe-aluminium engaphansi namanzi, ngakho akukho ukudluliswa kwe-aluminium okukhulu okwenzekayo. Ukuze kuhlangatshezwane ne-NSF/ANSI 61 kanye namazinga afanayo, inqubo ye-anodizing kumele ilawulwe ukuze kuqinisekiswe ukuthi kutholakala ungqimba oluqhubekayo, olungenayo imifantu.

Cha, ithusi lezinga lokudla lakhiwe ngokukhethekile ngaphandle komthofu ngakho-ke alikhiphi umthofu emanzini okuphuza ezingeni elingaphula izimfuneko ze-NSF/ANSI 61 noma ze-California Proposition 65. Ama-alloys endabuko ethusi ayequkethe kuze kufike ku-8% womthofu ukuze athuthukise ukusebenza kahle kokucutshungulwa, kodwa ithusi lanamuhla elingenamthofu lisebenzisa i-bismuth, i-silicon, noma ezinye izakhi ukuze ligcine ukusebenza kahle kokucutshungulwa kuyilapho likhipha umthofu ekwakhiweni, liqinisekisa ukuthintana okuphephile namanzi ahlanzekile okuphuza.

Ithusi elisezingeni lokudla ngokuvamile liyikhetho elingcono kwezokusebenza ngamanzi ashisayo ngoba linendawo yokuncibilika ephakeme (cishe 900-940°C), ukwanda okuncane kokushisa, kanye nezinga eliphakeme lokusebenza okuqhubekayo uma kuqhathaniswa ne-aluminium engu-6061. Ithusi lihlala lizinzile ngobukhulu emazingeni okushisa aphakeme futhi liyathethelela kakhulu ekushintsheni kokushisa, okwenza kube into ekhethwayo ezinhlelweni zamanzi ahlanzekile asebenza njalo ngamanzi angaphezu kuka-60°C.

Zozithile zombili lezi zinto zinikeza ukumelana nokugqwala okuqinile, kodwa ezindaweni ezahlukene. I-Brass imelana nokugqwala kahle emanzini ane-pH engathathi hlangothi (6-8) futhi ingakhiwa njenge-brass engamelani nokukhishwa kwe-zinc (DZR) ukuze imelane namanzi anamakhemikhali anamandla, nakuba ingaba sengozini yokuhlaselwa yi-chloride lapho igxile kakhulu. I-aluminium eqinisiwe ngokuqina (hard-anodized) inikeza ukumelana okumangalisayo nokugqwala okubangelwa ama-pits, ama-chloride, nama-asidi athambile ngoba ungqimba lwangaphezulu lwe-Al₂O₃ alunamsebenzi kakhulu, okwenza ithuthukise ezindaweni ezisogwini noma ezine-chloride ephezulu.

I-aluminium ye-6061 e-anodized iqinile kakhulu uma ixhunywa futhi ihlukaniswa njalo ngoba indawo ye-anodized ibonisa ukuqina okuphezulu kakhulu (350-500 Vickers), okumelana nokuklwebheka, ukugqwala, nokugqokwa okuhlikihlayo kangcono kakhulu kunendawo ethambile yethusi. Uqweqwe oluqinile luvikela i-aluminium engaphansi ekulimaleni okungaholela ekuqaleni kokugqwala, okwenza izinsimbi ze-aluminium ezi-anodized zifaneleke kakhulu ezinhlelweni ezihambayo ezixhunywa futhi zihlukaniswa kaningi.

Zombili izinto zingaqinisekiswa ku-NSF/ANSI 61, uma nje inqubo yokukhiqiza isebenzisa izinto ezingavuthiwe eziqinisekisiwe futhi umkhiqizo ophelile udlula ukuhlolwa kokukhishwa kanye nokuhlolwa kokusebenza. Ukuqinisekiswa kuhlobene nomkhiqizo othile kunokuba kuhlobene nezinto, ngakho kufanele uhlale uqinisekisa ukuthi i-camlock coupling ethile yomkhiqizi ithwala isitifiketi esifanele. I-Varicpand International ingahlinzeka ngemibhalo yesimo sesitifiketi semikhiqizo yethu ethile uma iceliwe.

Zombili zingahlala iminyaka engu-20 noma ngaphezulu ezinhlelweni zamanzi aphuzekayo ezakhiwe kahle, nakuba isikhathi sangempela sokusebenza sincike kumakhemikhali amanzi, ingcindezi, izinga lokushisa, nokuvama kokusetshenziswa. Ama-camlocks ethusi agqama ekufakweni okungapheli ngezimo zamanzi ezinzile, kuyilapho ama-camlocks e-aluminium ane-hard-anodized evame ukuhlala isikhathi eside ezinhlelweni eziphathwa njalo futhi echayeke emanzini ane-chlorine noma aguqulayo, ngoba indawo eqinile imelana nokugqokwa ngomshini nokuqala kokugqwala.

Yebo, ukugoqwa kwe-hard-anodized kumelana kakhulu ne-chlorine nezinye izinto zokubulala amagciwane ezivame ukusetshenziswa emanzini okuphuza kamasipala. Ungqimba lwe-aluminum oxide luzinzile ngokwamakhemikhali futhi alusabeli ne-chlorine emazingeni ajwayelekile atholakala ezinhlelweni zamanzi okuphuza (kuze kufike kuma-mg/L ambalwa), kanti i-aluminium engamboziwe ingase ithinteke ekubholeni ngaphansi kwezimo ezinjalo. Lokhu kwenza ama-camlocks e-aluminium hard-anodized abe ukukhetha okuhle kakhulu ezinhlelweni zokusabalalisa amanzi ane-chlorine.

Izindleko zomjikelezo wokuphila zincike kusetshenziswa. I-Brass ngokuvamile inezindleko eziphezulu zokuqala zempahla kodwa inikeza ukuphila isikhathi eside okungavamile ekufakweni okungapheli, okungadingi ukunakekelwa okuningi. I-aluminium eqinisiwe (hard-anodized) inezindleko eziphansi zokuqala futhi inesisindo esincane kakhulu, okunciphisa izindleko zokuthutha nokuphatha; ezinhlelweni eziphathwayo lapho izixhumi zivame ukuhanjiswa futhi zixhunywe, izici zokulula nokumelana nokugqokwa kwe-anodized aluminium zivame ukuletha izindleko eziphansi kakhulu zobunikazi ngokuhamba kwesikhathi.
