Umsesane wamanzi wase-china ukhetho lwempompo enodaka
Okokuqala, misela uhlobo lwe-china ye-slurry pump uhlobo olufunwa kakhulu yigesi esebenzayo, i-exhaust gas pressure, okanye i-vacuum degree ingaba. Xa impompo isebenza , kufuneka ubeke ingqalelo kule miba mibini ilandelayo :
1 njengoko kufuneka kwindawo ephezulu , eqhuba iqondo levacuum kwindawo ??enoxinzelelo olubalulekileyo okanye olubalulekileyo lokukhupha .
2 Kuphephe ukubaleka kwindawo ekufutshane nevacuum okanye uxinzelelo olukhulu lokukhupha . Ukusebenza kule ndawo , kungekuphela nje ukungasebenzi kakuhle , kodwa nokusebenza ngokungazinzi kakhulu, ukulungele ukungcangcazela kunye nengxolo. Kwimpompo ye-slurry yase-china ephezulu, ukusebenza kule ndawo , ngokuqhelekileyo i-cavitation iya kwenzeka, okubangelwa uphawu olucacileyo lwale nto yingxolo kunye nokungcangcazela kwimpompo. I-Cavitation inokubangela umonakalo kumzimba wempompo, i-impeller kunye nezinye iindawo , ukuze ipompo ingasebenzi.
Ngokwalo mgaqo, xa i-china efunekayo impompo ye-slurry okanye i-gas pressure ayiphezulu, i-priority ekhethiweyo kwimpompo yesigaba esisodwa. Ukuba iqondo le-vacuum okanye uxinzelelo oluphezulu lokukhupha, iimpompo zenqanaba elinye zihlala zingenako ukudibana, okanye zifuna impompo enkulu yerhasi isephantsi kweemeko eziphezulu ze-vacuum, ezifuna igophe elithe tyaba lokusebenza kwi-vacuum ephezulu, ukhetho lwempompo ezimbini. Ukuba ngaba ivacuum ifuneka kwi -710mmHg nangaphezulu, iringi yamanzi ekhethwayo – impompo yomoya enkulu okanye iringi yamanzi – iyunithi yokucoca iingcambu njengezixhobo zokufunxa.
Ukuba kuphela iimpompo ze-slurry zase-china zikhoyo, ukhetho lwempompo esebenzayo enye ingcono. Ngenxa yokuba isakhiwo sompompo obambeleyo silula, kulula ukwenza nokugcina, kunye neemeko eziphantsi kwe-vacuum cavitation resistance resistance. Ukuba kuphela i-compressor yegesi enkulu yokusetyenziswa, ngoko sebenzisa impompo esebenza kabini ngokufanelekileyo. Ngenxa yokuba igesi yempompo esebenza kabini, ubungakanani obuncinci, ubunzima obulula, amandla e-radial ukufumana i-automatic balance shaft ayiqhelekanga ukuphuka kokukhathala, ubomi obude bempompo.
Okwesibini, inkqubo efunekayo ukukhetha impompo yegesi , ngokungqinelana nempompo yohlobo olukhethiweyo lokuqala emva kwempompo, kodwa nangokwegesi efunekayo ukuze inkqubo isebenzise iimodeli zempompo. Malunga ne-china i-slurry yokupompa isantya sokukhetha kunye nexesha lokukhutshwa lingabalwa ngokubhekisela: Ifomula ye-vacuum.
