Ipompo yakho ihlala ilahlekelwa yiprime yayo, nto leyo ekunyanzela ukuba uyizalise ngesandla intambo yokufunxa kwakhona. Oku kuchitha ixesha, kubeke emngciphekweni wokutshisa i-motor yepompo, kwaye kumise ukuhamba kwamanzi okubalulekileyo.

A Ivalvu yeenyawo zePVCluhlobo lwevalvu yokujonga edityaniswe nesihluzo, efakwe ezantsi komtya wokufunxa wepompo. Umsebenzi wayo kukugcina amanzi kumbhobho, ukugcina ipompo ilungelelanisiwe, kunye nokuvala inkunkuma.

Ndikhumbula incoko noBudi malunga neprojekthi enkulu yokunkcenkceshela eyayibonelelwa ngomnye wabathengi bakhe. Babeneengxaki ezingapheliyo ngeempompo zabo. Iimpompo zazifakelwe ngaphezulu kweetanki zamanzi, kwaye qho kusasa abasebenzi kwakufuneka bachithe ixesha elininzi bezifaka kwakhona iiprimeyitha. Sakhawuleza safumanisa ingxaki: babengasebenzisiiivalvu zeenyawo. Licandelo elincinci, elingabizi kakhulu, kodwa indima yalo kwinkqubo inkulu kakhulu. Ukuchaza indlela le valve ilula esombulula ngayo ingxaki ekhathazayo nenokuba yindleko enkulu ngumzekelo ogqibeleleyo wendlela icandelo elifanelekileyo elenza ngayo umahluko omkhulu.

Yintoni esetyenziswa ziivalvu zeenyawo zePVC?

Useta ipompo yokutsala amanzi emthonjeni, etankini, okanye edamini. Kodwa ungawathintela njani amanzi ukuba angaphumi kwaye ugcine isanti okanye amagqabi ephuma kwipompo yakho?

Iivalvu zeenyawo zePVC zisetyenziswa kwisiphelo sokungenisa imigca yokufunxa kuyo nayiphi na ipompo engantywiliselwanga emanzini. Zinemisebenzi emibini ebalulekileyo: ukugcina ipompo ikwi-primer kunye nokucoca amanzi ngaphambi kokuba angene kwinkqubo.

Masiwahlule la magama mabini, kuba omabini abalulekile kwinkqubo yokumpompa esempilweni. Okokuqala kukufaka iprimer. Uninzi lweempompo eziqhelekileyo, njengeempompo ze-centrifugal, zilungile ekuhambiseni amanzi kodwa azilunganga ekuhambiseni umoya. Zifuna ikholamu eqinileyo yamanzi kumbhobho wokufunxa ukuze zisebenze. Xa ipompo iyeka, umxhuzulane ufuna ukutsala onke loo manzi abuyele ezantsi emthonjeni okanye etankini. Ivalvu yeenyawo isebenza njengeucango oluya calanyeAmanzi angatsalwa ngaphakathi, kodwa akanakukwazi ukuphuma kwakhona. Oku kugcina umbhobho ugcwele kwaye ipompo "ilungisiwe" kwaye ilungele ukusebenza. Okwesibini yiukuhluza. Isikrini, okanye isihluzo, esingaphandle kwevalvu sisixhobo sokuqala sokuzikhusela. Sithintela amagqabi, iingqalutye, iintlanzi, kunye nezinye izinto ezinkulu ezingafunekiyo ukuba zingene kumbhobho. Oku kuthintela izinto ezingafunekiyo ukuba zingaxinanisi i-impeller yepompo, nto leyo enokubangela ukuba iguge okanye ingasebenzi ngokupheleleyo.

Isicelo	Kutheni ifuneka
Iinkqubo zamanzi eMithombo	Igcina ipompo ilungisiwe kwaye ithintela isanti ukuba ingangeni.
Ukunkcenkceshela	Ithintela ukulahleka kwe-prime kwaye ithintela ukhula/inkunkuma ukuba ingavali ii-sprinkler.
Amadama kunye namaLwandle	Ihluza izinto eziphilayo zasemanzini kunye nenkunkuma, igcina ubuncwane bayo buphezulu.
Imingxunya yeSump	Iqinisekisa ukuba ipompo yesump ikulungele ukusebenza ngoko nangoko xa kufuneka.
Amatanki Amanzi	Ibamba iprime yeempompo ezitsala amanzi ukuze asasazwe.

Yintoni injongo yevalvu yeenyawo?

Uyazi ukuba udinga ivalvu yonyawo, kodwa awuyiqondi kakuhle indlela esebenza ngayo. Ngaphandle kokuqonda "isizathu," kunzima ukuchaza ukubaluleka kwayo okanye ukusombulula ingxaki kwinkqubo enengxaki ngokufanelekileyo.

Eyona njongo iphambili yevalvu yonyawo kukubamba iprime yepompo. Ifezekisa oku ngokusebenza njengevalvu yokujonga evumela ukuhamba kwicala elinye kuphela—ukungena kumbhobho, kungekhona ukuphuma kuwo.

Cinga ngayo njengomgcini-sango ezantsi kombhobho wakho wokufunxa. Umbindi wayo nayiphi na ivalvu yenyawo yiivalvu yokujongaindlela yokusebenza. Ngaphakathi kwiivalvu zethu zePntek, kukho iflephu okanye ibhola encinci, edla ngokubanjwa sisipringi. Xa ipompo ivula, idala ukufunxa. Olu xinzelelo lokufunxa lunamandla ngokwaneleyo ukutsala iflephu livuleke, livumela amanzi ukuba angene kumbhobho. Amanzi ke aqukuqela aye kwipompo aze aphume aye kwinkqubo yakho. Xa ipompo icima, ukufunxa kuyanyamalala. Ngoku, ubunzima bekholamu yonke yamanzi kumbhobho butyhala umva kwiflephu. Olu xinzelelo, ludibene nesipringi, luvala iflephu ngoko nangoko. Oku kubamba amanzi kumbhobho. Eli nyathelo lilula liyinjongo epheleleyo: ukuqinisekisa ukuba xa ufuna ukuqala ipompo kwakhona, inamanzi alungele ukuhamba, ukuthintela ukuba yome.

Yeyiphi engcono, ivalvu yentsimbi okanye yePVC?

Uyazibona zombini iivalvu zebrass kunye nezePVC foot. Kufuneka wazi ukuba zeziphi oza kuzicebisa, kuba ukukhetha izinto ezingafanelekanga kunokukhokelela ekuboleni, ekungcoleni, okanye kwiindleko ezongezelelweyo ezingeyomfuneko kubathengi bakho.

Akukho nanye kwezi zilungileyo kuzo zonke iindawo; ukhetho olungcono luxhomekeke kwisicelo. I-PVC ingcono kakhulu ekumelaneni nokugqwala, ukuhambelana kweekhemikhali, kunye nexabiso. I-Brass ingcono kwizicelo zoxinzelelo oluphezulu kunye neemeko ezifuna ukuqina okuphezulu komzimba.

Lo ngumbuzo endihlala ndiwuxoxa noBudi kuba abathengi bakhe bajongene neemeko ezahlukeneyo. Kubathengi bakhe abaninzi kwezolimo, ukulima iintlanzi, okanye ukuhanjiswa kwamanzi ngokubanzi, ndisoloko ndicebisa i-PVC. Isizathu silula: ukugqwala. Amanzi e-Indonesia, ingakumbi amanzi angaphantsi komhlaba, anokuba neeminerali ezingcolisa isinyithi ngokuhamba kwexesha. I-brass inokugqwala kancinci okanye ihlupheke ngenxa yokususwa kwe-zinc, ekugqibeleni iyeke ukusebenza. I-PVC yiplastiki, ngoko ke ayichaphazeleki ngokupheleleyo kukugqwala nokugqwala. Iya kuhlala ixesha elide kwezi ndawo. Ikwalula kakhulu kwaye ayibizi kakhulu. Nangona kunjalo, ukuba umthengi ujongene noxinzelelo oluphezulu kakhulu okanye kwimeko apho ivalvu inokutshayiswa okanye ikhuhlwe ngamatye (njengakumsinga ohamba ngokukhawuleza), ngoko ukuqina komzimba kwe-bronze kunokuba lolona khetho lungcono. Kodwa malunga ne-90% yezicelo zokumpompa amanzi eziqhelekileyo, i-PVC inikezela ngexabiso elifanelekileyo kunye nobomi obude benkonzo.

Iivalvu zeenyawo zePVC vs. Brass

Uphawu	Ivalvu yeenyawo zePVC	Ivalvu yeenyawo zeBrass
Ukumelana nokugqwala	Igqwesile	Kulungile, kodwa kunokubola
Ixabiso	Iphantsi	Phezulu
Ubunzima	Kukhanya Kakhulu	Inzima
Ukumelana neekhemikhali	Igqwesile	Imbi
Uvavanyo loxinzelelo	Ilungele ukusetyenziswa ngokwesiqhelo	Ilungele kakhulu uxinzelelo oluphezulu
Eyona ilungileyo	Imithombo, unkcenkceshelo, amatanki, amachibi	Ukusetyenziswa kwemizi-mveliso okunoxinzelelo oluphezulu

Ngaba ipompo ingasebenza ngaphandle kwevalvu yeenyawo?

Unomthengi ofuna ukunciphisa iindleko aze abuze ukuba angalishiya na ivalvu yonyawo ngaphandle. Kufuneka umnike impendulo ecacileyo malunga neengozi ezibandakanyekayo kwesi sigqibo.

Ewe, ipompo ye-centrifugal ingasebenza ngaphandle kwevalvu yeenyawo, kodwa ayilunganga kakhulu. Iya kulahlekelwa yiprime yayo ngalo lonke ixesha ivala, nto leyo edinga ukuphinda iprime ngesandla rhoqo kwaye ibeke emngciphekweni wokonakala okukhulu kwepompo.

Ndingamxelela lo mthengi ukuba ukuzama ukonga iidola ezimbalwa kwivalvu yeenyawo kunokumbangela ukuba ahlawule amakhulu eedola kwimpompo entsha. Nantsi into eyenzekayo ngaphandle kwevalvu yeenyawo. Ipompo iyabaleka, ize ime. Onke amanzi kumbhobho wokufunxa abuyela equleni ngoko nangoko. Ngexesha elizayo xa uvula ipompo, umbhobho ugcwele umoya. I-impeller yepompo iyajikeleza nje, ayikwazi ukudala ukufunxa. Oku kubizwa ngokuba "kukubaleka komile." Amanzi ahamba ngepompo ayimveliso nje kuphela; ikwayinto epholisayo kunye ne-lubricant yeempompo zokufunxa. Xa ipompo yomile, ezi mpompo zishushu kakhulu ngokukhawuleza. Zinokunyibilika okanye ziqhekeke ngaphantsi komzuzu, zibangele umonakalo ongapheliyo kunye nokuvuza. Indlela ekuphela kwayo yokuyenza isebenze kwakhona kukugalela amanzi ngesandla kumgca wokufunxa ide igcwale. Ukwenza oku rhoqo yingxaki enkulu eyonakalisa ngokupheleleyo injongo yenkqubo yokufunxa ezenzekelayo.

Isiphelo
