Lapho Iphampu Iqala, Ingabe Kufanele Sivale I-Valve Yokuphuma Noma Cha?

Lapho Iphampu Iqala, Ingabe Kufanele Sivale I-Valve Yokuphuma Noma Cha?

Ngokuvamile, qala i-iphampu ye-centrifugal, ngokusho kokucaciswa kufanele kube, igumbi lokuqala lokupompa eligcwele okuphakathi, vala i-valve yokuphuma, bese uvulafutha, inhloso iwukuthi: ngakolunye uhlangothi ukuvimbela ukuqala kwamanje umonakalo omkhulu kakhulu ku-motor;Ngakolunye uhlangothi, vimbela ukulahlekelwa okusheshayo kwengcindezi ngemva kokuqalafutha, Imiphumelafuthai-cavitation.Kodwa izinkinga eziningi azikwazi ukwenziwa jikelele!

Ngokugeleza okuphansi nekhanda eliphansiamaphampu, ukuvala noma ukuvala i-valve yokuphuma akuyona inkinga.

Kokukhuluamaphampu, i-outlet ivame ukuvulwa kancane ukuvimbela umehluko wengcindezi phakathi kwangaphambili nangemuva kwe-valve ngemva kokuqala, futhi i-valve yokuphuma akulula ukuyivula, ngakho-ke ukuvulwa kwe-valve yokuphuma kuvulwa kancane.

Abanyeamaphampu centrifugalizovula kancane i-valve yokuphuma ngenxa yokushisa kanye nezinye izidingo.

Uma ihambisana nokumunca, ukuvala ngokugcwele i-valve yokuphuma, bese uvula i-valve (hhayi i-self-priming pump), kodwa futhi uvule i-valve yokukhipha ipompo.

Kwezinye izimo ezikhethekile, i-valve yokuphuma ayikwazi ukuvulwa, isibonelo, i-propylene ewuketshezi, uma i-valve yokuphuma ivula kuqala, i-propylene iyahwamuka, iphampu ngeke ikwazi ukucindezela, ngakho-ke kufanele ivalwe kuqala, iphampu futhi bese uvula ngokushesha i-valve yokuphuma.

Okungenhla kukhona amaphampu centrifugal.Kwezinye izinhlobo zamaphampu, isimo simi kanje :

1. Izici ezinkulu zokuqalisa ukugeleza kwepompo ye-axial flow-i-valve evuleke ngokugcwele

Amandla we-shaft wokugeleza kwe-axialfuthainkulu kakhulu esimweni sokugeleza okunguziro, okungama-140 % ~ 200 % wamandla alinganiselwe we-shaft, futhi amandla mancane kakhulu esimweni sokugeleza okuphezulu.Ngakho-ke, ukuze kuncishiswe ukuqala kwamanje, izici zokuqala zamandla we-shaft kufanele zibe ukuqala kokugeleza okukhulu (okungukuthi, ukuqala kwe-valve evulekile ngokugcwele).

2. Izici zokuqalisa zephampu yokugeleza okuxubile-ukuqalisa kwe-valve evuleke ngokugcwele

Amandla we-shaft wokugeleza okuxubilefuthaesimweni sokugeleza okuyiziro siphakathi kwalokhu okubili okungenhlaamaphampu, okungu-100 % ~ 130 % wamandla alinganiselwe.Ngakho-ke, izici zokuqala zepompo yokugeleza okuxubile kufanele futhi zibe phakathi kwalokhu okubili okungenhlaamaphampu, futhi kungcono ukuqala ngokuvula i-valve egcwele.

3. Izici zokuqalisa zephampu ye-vortex evule ngokugcwele ukuqala kwe-valve

Amandla we-shaft we-vortexfuthainkulu kunazo zonke esimweni sokugeleza kwe-zero, okungama-130 % ~ 190 % wamandla alinganiselwe we-shaft.Ngakho-ke, kufana nokugeleza kwe-axialfutha, izici zokuqalisa zepompo ye-vortex kufanele zibe ukuqala kokugeleza okukhulu (okungukuthi, ukuqala kwe-valve egcwele).
