Iphampu yakho ilahlekelwa yi-prime yayo njalo, okukuphoqa ukuthi ugcwalise kabusha umugqa wokumunca ngesandla kaninginingi. Lokhu kuchitha isikhathi, kuyingozi yokushisa injini yephampu, futhi kumise ukugeleza kwamanzi okubalulekile.

A I-valve yonyawo lwe-PVCuhlobo lwevalvu yokuhlola ehlanganiswe nesihluzo, efakwe phansi kakhulu komugqa wokumunca wephampu. Umsebenzi wayo ukugcina amanzi ephayiphini, ukugcina iphampu ilungele, nokuvimba udoti.

Ngikhumbula ingxoxo noBudi mayelana nephrojekthi enkulu yokunisela eyayihlinzekwa yiklayenti lakhe. Babenezinkinga eziqhubekayo ngamaphampu abo. Amaphampu ayefakwa ngaphezu kwamathangi amanzi, futhi njalo ekuseni abasebenzi kwakudingeka bachithe isikhathi esiningi bewafaka kabusha. Sasheshe sabona inkinga: babengasebenzisiamavalvu ezinyawo. Kuyingxenye encane, engabizi kakhulu, kodwa indima yayo ohlelweni inkulu kakhulu. Ukuchaza ukuthi le valve elula ixazulula kanjani inkinga ekhungathekisayo nengase ibize kuyisibonelo esiphelele sendlela ingxenye efanele eyenza ngayo umehluko.

Iyini ukusetshenziswa kwama-valve ezinyawo ze-PVC?

Usetha iphampu yokudonsa amanzi emthonjeni, ethangini, noma echibini. Kodwa ungawavimba kanjani amanzi ukuthi angaphumi futhi ugcine isihlabathi noma amaqabunga ephampu yakho elimazayo?

Ama-valve ezinyawo ze-PVC asetshenziswa ekugcineni kokungenisa kwemigqa yokumunca kunoma iyiphi ipompo engacwili. Afeza imisebenzi emibili ebalulekile: ukugcina ipompo ibekwe kahle kanye nokuhlunga amanzi ngaphambi kokuba angene ohlelweni.

Ake sihlukanise lokhu kusetshenziswa okubili, ngoba kokubili kubalulekile ohlelweni lwephampu olunempilo. Okokuqala ukufaka i-primer. Amaphampu avamile kakhulu, njengamaphampu e-centrifugal, ayakwazi ukuhambisa amanzi kodwa ayasiza ekuhambiseni umoya. Adinga ikholomu eqinile yamanzi epayipini lokumunca ukuze asebenze. Lapho iphampu ima, amandla adonsela phansi afuna ukudonsa wonke lawo manzi abuyele phansi emthonjeni noma ethangini. I-valve yonyawo isebenza njenge-umnyango oqonde ngakwesokudlaAmanzi angadonswa ngaphakathi, kodwa awakwazi ukuphuma. Lokhu kugcina ipayipi ligcwele futhi ipompo “ifakwe i-primer” futhi ilungele ukusebenza. Okwesibiliukuhlunga. Isikrini, noma isihluzo, esingaphandle kwevalvu siyindlela yokuqala yokuzivikela. Sivimba amaqabunga, amatshe amancane, izinhlanzi, kanye nezinye izinsalela ezinkulu ukuthi zingamuncwa epayipini. Lokhu kuvimbela izinsalela ukuthi zingaminyanisi i-impeller yephampu, okungabangela ukuthi iguge noma yehluleke ngokuphelele.

Izicelo Ezivamile Zama-PVC Foot Valves

Isicelo	Kungani Kudingeka
Izinhlelo Zamanzi Emithombo	Igcina ipompo ilungisiwe futhi ivimbela isihlabathi ukuthi singangeni.
Ukunisela	Kuvimbela ukulahleka kwe-prime futhi kuvimbele ukhula/udoti ekuvaleni ama-sprinkler.
Amachibi namachibi	Ihlunga izinto eziphilayo zasemanzini kanye nenhlabathi, igcina umswakama uphezulu.
Imigodi Yezimbobo	Iqinisekisa ukuthi iphampu ye-sump ikulungele ukusebenza ngokushesha uma kudingeka.
Amathangi Amanzi	Ibamba i-prime yamaphampu adonsa amanzi ukuze asakazwe.

Iyini injongo yevalvu yonyawo?

Uyazi ukuthi udinga i-valve yonyawo, kodwa awuqondi ngempela indlela esebenza ngayo. Ngaphandle kokuqonda ukuthi “kungani,” kunzima ukuchaza ukubaluleka kwayo noma ukuxazulula inkinga yesistimu enephutha ngempumelelo.

Inhloso eyinhloko yevalvu yonyawo ukubamba i-prime yephampu. Ifeza lokhu ngokusebenza njengevalvu yokuhlola evumela ukugeleza ohlangothini olulodwa kuphela—kungene epayipini, hhayi ukuphuma kulo.

Cabanga ngakho njengomlindi wesango phansi kwepayipi lakho lokumunca. Ingaphakathi lanoma yiliphi i-valve yonyawo liyi-ivalvu yokuhlolaindlela yokusebenza. Ngaphakathi kwamavalvu ethu e-Pntek, kukhona i-flap noma ibhola elincane, elivame ukubanjwa yisipilingi. Uma ipompo ivula, idala ukumunca. Lo mfutho wokumunca unamandla anele ukudonsa i-flap ivuleke, okuvumela amanzi ukuthi angene epayipini. Amanzi abe esegeleza aye epomponi bese ephuma aye ohlelweni lwakho. Lapho nje ipompo icima, ukumunca kuyanyamalala. Manje, isisindo sekholomu yonke yamanzi epayipini sisunduzela phansi ephepheni. Lo mfutho, ohlangene nesipilingi, uvala i-flap ngokushesha. Lokhu kubamba amanzi epayipini. Lesi senzo esilula siyinhloso yonke: ukuqinisekisa ukuthi uma udinga ukuqala ipompo futhi, inamanzi alungele ukuhamba, okuvimbela ukuthi yome.

Yikuphi okungcono, ama-valve ezinyawo zethusi noma e-PVC?

Uyabona ama-valve ezinyawo zethusi kanye ne-PVC atholakalayo. Udinga ukwazi ukuthi iyiphi ongayincoma, ngoba ukukhetha izinto ezingalungile kungaholela ekugqwaleni, ekungcoleni, noma ezindlekweni ezengeziwe ezingadingekile kumakhasimende akho.

Akukho okunye okungcono kakhulu emhlabeni wonke; ukukhetha okungcono kuncike ekusetshenzisweni. I-PVC ingcono kakhulu ekumelaneni nokugqwala, ukuhambisana namakhemikhali, kanye nezindleko. Ithusi lingcono ekusetshenzisweni okunomfutho ophezulu kanye nezimo ezidinga ukuqina okuphezulu ngokomzimba.

Lona umbuzo engivame ukuwuxoxa noBudi ngoba amakhasimende akhe abhekene nezimo ezahlukene. Kwabaningi bamakhasimende akhe kwezolimo, ukufuywa kwezinhlanzi, noma ukudluliswa kwamanzi okuvamile, ngihlala ngincoma i-PVC. Isizathu silula: ukugqwala. Amanzi e-Indonesia, ikakhulukazi amanzi angaphansi komhlaba, angaba namaminerali angcolisa izinsimbi ngokuhamba kwesikhathi. Ithusi lingagqwala kancane noma lihlupheke ngenxa yokususwa kwe-zinc, ekugcineni lihluleke. I-PVC iyipulasitiki, ngakho-ke ayigonyelwa ngokuphelele ukugqwala nokugqwala. Izohlala isikhathi eside kakhulu kulezi zindawo. Ilula kakhulu futhi ishibhile. Kodwa-ke, uma iklayenti libhekene nokucindezeleka okuphezulu kakhulu noma esimweni lapho ivalvu ingase ishaywe noma ikhuhlwe ngamatshe (njengasemfuleni ohamba ngokushesha), khona-ke ukuqina okungokomzimba kwethusi kungaba ukukhetha okungcono. Kodwa cishe ku-90% wezicelo ezijwayelekile zokupompa amanzi, i-PVC inikeza inani elihle kakhulu kanye nokuphila isikhathi eside kwenkonzo.

Amavalvu Ezinyawo ze-PVC vs. Brass

Isici	I-PVC Foot Valve	I-Brass Foot Valve
Ukumelana Nokugqwala	Kuhle kakhulu	Kuhle, kodwa kungalimaza
Izindleko	Phansi	Phezulu
Isisindo	Kukhanya Kakhulu	Okunzima
Ukumelana namakhemikhali	Kuhle kakhulu	Kubi
Isilinganiso Sokucindezela	Kuhle ukusetshenziswa okujwayelekile	Kuhle kakhulu ekucindezelweni okuphezulu
Okuhle Kakhulu Kwaba	Imithombo, ukuchelela, amathangi, amachibi okubhukuda	Ukusetshenziswa kwezimboni okunomfutho ophezulu

Ingabe iphampu ingasebenza ngaphandle kwevalvu yonyawo?

Unekhasimende elifuna ukunciphisa izindleko futhi libuze ukuthi lingashiya yini i-valve yonyawo ngaphandle. Udinga ukubanika impendulo ecacile mayelana nezingozi ezihilelekile kulesi sinqumo.

Yebo, ipompo ye-centrifugal ingasebenza ngaphandle kwevalvu yonyawo, kodwa kungumqondo omubi kakhulu. Izolahlekelwa yi-prime yayo njalo uma icisha, okudinga ukushintshwa kabusha ngesandla njalo futhi ibeke engcupheni yokulimala okukhulu kwepompo.

Ngingatshela leli khasimende ukuthi ukuzama ukonga amadola ambalwa ku-valve yezinyawo kungagcina kubabize amakhulu amadola ngepompo entsha. Nakhu okwenzekayo ngaphandle kwe-valve yezinyawo. Ipompo iyagijima, bese iyama. Wonke amanzi asepayipini lokumunca abuyela emthonjeni ngokushesha. Ngesikhathi esilandelayo lapho uvula ipompo, ipayipi ligcwele umoya. I-impeller yepompo izojikeleza nje, ingakwazi ukudala ukumunca. Lokhu kubizwa ngokuthi "ukugijima komile." Amanzi ageleza ngepompo akuwona nje umkhiqizo; futhi ayi-coolant kanye ne-lubricant ye-seal yepompo. Uma ipompo yomile, i-seal ishisa kakhulu ngokushesha. Ingancibilika noma iqhekeke ngaphansi komzuzu, ibangele umonakalo ongapheli kanye nokuvuza. Okuwukuphela kwendlela yokuyenza isebenze futhi ukuthulula amanzi ngesandla emgqeni wokumunca kuze kube yilapho egcwele. Ukwenza lokhu njalo kuyisiphazamiso esikhulu esichitha ngokuphelele injongo yesistimu yokumunca okuzenzakalelayo.

Isiphetho

A I-valve yonyawo lwe-PVCiyingxenye ebalulekile, engabizi kakhulu evikela ipompo yakho ngokuyigcina isesimweni esihle futhi ihlunga udoti. Iyingxenye ebalulekile yesistimu yamanzi ehlala isikhathi eside futhi esebenza kahle.
