Okufanele ukwenze uma ikhanda le-self priming pump likhethwe liphezulu kakhulu

Ukukhetha ikhanda eliphezulu for theiphampu yokuzenzelaayisebenzisi nje amandla eqile kuphela, kodwa ingase futhi ithinte isikhathi sokuphila sepompo elizikhiphayo. Ukubhekana nalesi simo, qala ngokunikeza isixazululo esisekelwe kumgomo wokusebenza wephampu:

1. Amaphampu e-Centrifugal self priming. Uma iphampu yokumunca ngokwayo isekelwe kumgomo we-centrifugal, empeleni iyiphampu ephakathi nendawo ekwazi ukuzimunca yona ngokwayo. Ukukhetha ikhanda eliphezulu kungaba yingozi enkulu empompini.

(1) Ukusika i-impeller yepompo ezizenzelayo: Uma inhloko yamanje yepompo eziziqhumisayo iphezulu kakhulu futhi ichezuka ngokuphawulekayo esidingweni sangempela, futhi ngokubala, uma ukusebenza kahle kwepompo namandla e-shaft kungaqinisekiswa finyelela uhla olufanele, indlela eshesha kakhulu ukusika i-impeller ye-self-priming pump. Ukusika ngokweqile kwe-impeller kuzonciphisa ukusebenza kokuzidonsa kwepompo.

(2) Ukulungisa amapharamitha wokusebenza: Uma kungenakuphazamiseka ukufaka esikhundleni se-impeller, ungazama ukulungisa imingcele yokusebenza yepompo yokudonsa ngokwakho, njengokunciphisa isivinini ngokuguqulwa kwemvamisa, ukunciphisa ikhanda ngezinga elithile. Kodwa le ndlela izophinde inciphise izinga lokugeleza kwepompo, futhi kungenzeka ukuthi kunqunywe ngokusekelwe kuhlobo oluthile lwepompo kanye nezimo zokusebenza.

(3) Ukwandisa ingcindezi emuva: Ngokukhuphula umfutho wangemuva wepompo, njengokuvala ama-valve athile aphumayo, izinga lokugeleza kwepompo elizikhiphayo lingavinjelwa, ngaleyo ndlela kuncishiswe ikhanda ngokwezinga elithile. Kodwa le ndlela ingase iholele ekwehleni kokusebenza kwephampu.

(4) Ukulungiswa kwemvume:Amaphampu emfucumfucu azithungelayongama-impellers avulekile noma avulekile anganciphisa imingcele yepompo ngokulungisa imvume eqondile phakathi kwe-impeller kanye nepuleti elingagugi. Ukwenyuswa kwemvume kuzophinde kwehlise izinga lokumunca kanye nezinga lokugeleza kwephampu, ngaleyo ndlela kuthinte ukusebenza kahle okuphelele kwepompo.

2. Iphampu yokuzilungiselela yona enamandla omthamo wevolumu. Uma inhloko yepompo yokufuduka enhle ikhethwe iphezulu kakhulu, ngaphandle kokucindezela okukhulu kokuphumayo, ngokuvamile ayinawo umthelela okhuphukile epompo. Ngokuphambene namaphampu ayi-centrifugal, iphampu yokususa evumayo isebenzisa ikhanda eliphansi kanye nomthwalo wemoto omncane.

Kufanele kuqashelwe ukuthi ngaphambi kokwenza noma yiziphi izinguquko noma ukushintshwa, umuntu kufanele aqale aqonde isimiso sokusebenza nezici zokusebenza zepompo eliziqhumisayo, futhi akhethe isixazululo esifanele ngokusekelwe esimweni sangempela. Khonamanjalo, ukuze kuqinisekiswe ukuphepha nokusebenza ngempumelelo komsebenzi, kuyanconywa ukuthi uxhumane nochwepheshe bephampu noma onjiniyela ukuze uthole isiqondiso nosizo.
