Indandatho yamanzi yase-china yokukhetha iphampu ye-slurry
Okokuqala, thola uhlobo lwepompo yodaka lwase-china oludingwa kakhulu igesi esebenzayo, ingcindezi yegesi yokukhipha umoya, noma i-vacuum degree.Lapho iphampu isebenza , udinga ukunaka izici ezimbili ezilandelayo :
1 njengoba kudingekile endaweni ephezulu , esebenzisa idigri ye-vacuum endaweni ??yengcindezi ebucayi noma ebucayi yokukhipha .
2 Gwema ukugijima eduze ne-vacuum ephezulu noma ukucindezela okukhulu kokukhipha .Ukusebenza kule ndawo , hhayi nje ukungasebenzi kahle , kodwa futhi kusebenza engazinzile kakhulu, ejwayele ukudlidliza nomsindo.Ukuze uthole iphampu ye-china ephezulu ye-slurry, ukusebenza kule ndawo, ngokuvamile i-cavitation izokwenzeka, okuholela esibonakaliso esicacile salesi senzakalo umsindo nokudlidliza kupompo.I-Cavitation ingabangela umonakalo emzimbeni wepompo, i-impeller nezinye izingxenye , ukuze iphampu ingasebenzi.
Ngokwalesi simiso, lapho ipompo ye-china slurry edingekayo noma ingcindezi yegesi ingekho phezulu, okubalulekile okukhethiwe kupompo yesiteji esisodwa.Uma idigri ye-vacuum noma ingcindezi yokukhipha ephezulu , amaphampu esiteji esisodwa ngokuvamile awakwazi ukuhlangabezana, noma adinga iphampu yegesi enkulu ngaphansi kwezimo ze-vacuum eziphezulu , okudinga ijika eliphansi lokusebenza ku-vacuum ephezulu, ukukhetha kwephampu ezimbili.Uma i-vacuum idingeka ku-710mmHg noma ngaphezulu, iringi yamanzi ozikhethela yona – iphampu yomoya enkulu noma iringi yamanzi – Iyunithi yomshini wokukhipha izimpande njengemishini yokuhlanza.
Uma kuphela amaphampu e-slurry ase-china etholakala, ukukhethwa kwepompo elibambayo elilodwa kungcono.Ngoba ukwakheka kwephampu ebambe iqhaza eyodwa ilula, kulula ukuyikhiqiza nokuyigcina, kanye nezimo ezingaphansi kokumelana okuphezulu kwe-vacuum cavitation.Uma kuphela i-compressor yegesi enkulu esetshenziswayo, sebenzisa iphampu esebenza kabili efaneleka kakhulu.Ngoba igesi yepompo esebenza kabili , usayizi omncane , isisindo esilula, amandla e-radial ukuze uthole i-othomathikhi ye-balance shaft ayijwayele ukuphuka ngokukhathala, impilo ende yepompo.
Okwesibili, uhlelo oludingekayo ukukhetha iphampu yegesi , ngokusho kwepompo yohlobo olukhethiwe lokuqala emva kwepompo , kodwa futhi ngokusho kwegesi edingekayo ukuze uhlelo lusebenzise amamodeli wepompo.Mayelana nokukhethwa kwesivinini sokupompa kwe-china kanye nesikhathi sokukhipha singabalwa ngereferensi : Ifomula ye-Vacuum.
