I-slurry volume loss runtime I-Slurry iyasebenza, ingcindezi yepompo yamanzi emzimbeni wonke ayilingani, indawo yokucindezela okukhulu, kukhona indawo yokucindezela okuphansi. Njengoba izidingo zesakhiwo, kunezikhala eziningi emzimbeni wephampu, lapho igebe elizungeze uhla lokucindezela, uketshezi luzogeleza lusuka endaweni yokucindezela okukhulu luye endaweni enengcindezi ephansi, le ngxenye yendawo yokucindezela okukhulu koketshezi ibuyele phakathi. isifunda sokucindezela okuphansi, ngenkathi sigeleza ngokusebenza kwamandla kutholakala lapho i-impeller, kodwa hhayi ukusetshenziswa okuphumelelayo, kodwa ukujikeleza komzimba wepompo, ngoba igebe lokunqoba ukumelana nokudliwa, lokhu kulahlekelwa kwamandla kubizwa ngokuthi ukulahlekelwa kwevolumu.
Njengoketshezi oluphuma engxenyeni ye-impeller empompini ebuyela emuva, olungakhishelwa ngaphandle kwepompo, izinga lokugeleza lokuphuma kwephampu Q lesilinganiso sangempela sesilinganiso sokugeleza nge-impeller Q 'kube kuncane.
Ukuhlukaniswa kwevolumu yokulahleka
(1) lapho umnyango we-impeller, i-impeller kanye nomzimba wepompo kunegebe elincane lokuvala. Ingcindezi engaphakathi komgodi wokungenisa umoya wepompo kunophezulu, ngakho-ke kukhona igebe elincane elisuka oketshezini lwesitoko ngophawu libuyela ekuphumeni kwe-impeller inlet. Le ngxenye yoketshezi njenge-impeller yebhidi ephumelelayo isetshenziswa ngokuphumelelayo, futhi ukulahlekelwa kuwukunqoba ukumelana kwegebe lophawu. Ngokuvamile, le ngxenye yokulahlekelwa kwamandla ibizwa ngokuthi ukulahlekelwa kwe-seal ring leakage. Amanzi atholakalayo ageleza ngomshini wefomula yokubala inani lokuvuza kwendandatho yokuvala q1 (m ^ 3 / s): uketshezi olomile noma uketshezi olunoketshezi oluhambisana nephampu yokusanhlamvu, imvume yendandatho yophawu kufanele ibe nkulu kunenani elikuThebula 2 -1 kancane. Igebe lendandatho yokuvala uphawu l linganqunywa ngokuya ngesakhiwo esithile.
(2) Ngokuvamile ibhalansi ye-centrifugal axial force kuzo zombili izikhungo, njengembobo yokulinganisa (Umdwebo 2-11) kanye ne-balance plate nokunye. Nakuba ingxenye yoketshezi etholakala ku-impeller yamandla, kodwa ayisetshenziswanga kahle futhi idliwe ukuze kunqobe ukumelana nokulinganisa indlela, nayo eyingxenye yokulahlekelwa kwevolumu ekulahlekeni kwamandla. Ekwamukelweni kokubala kwe-multi-stage pump balancing disc yenani lokuvuza kwamanzi kuzoxoxwa ngakho eSahlukweni VII. On inani ukuvuza ngokusebenzisa imbobo ibhalansi kungenziwa cishe by the formula (2-13), kuba khona ibhalansi imbobo futha ukusebenza kahle ngokuvamile 3-6%.
Ngaphezu kwalokho, iphampu enezigaba eziningi, ngaphezu kwalezi zigaba ezimbili ezingenhla, iyingxenye yokulahlekelwa kwevolumu yokuvuza, ayikho ingxenye yokuvuza kokulahlekelwa kwevolumu yokuvula. Kumaphampu ezigaba eziningi ngokuvamile kukhona ipuleti yokuhlukanisa izinga, njengoba izinga loketshezi ngemva kwepuleti lokuhlukanisa ingcindezi liyahlukahluka,umkhiqizi wepompo ye-slurryngakho ingxenye yoketshezi idlula ezingeni ibuyela egebeni lepuleti phakathi kohlangothi lwe-impeller lwe-pre-clearance, igebe lokuvuza phakathi kwezinga loketshezi, phakathi kwe-impeller kanye ne-guide vane backlash ngemva kokuxubana noketshezi olusuka ku-impeller, guide vanes kanye namaqabunga e-ABM, kodwa futhi ngegebe lezinga phakathi kwe-impeller emuva ku-pre-backlash, njalonjalo. Njengoba le ngxenye ye-liquid ingadluli ku-impeller, ayithinti ukugeleza kwepompo, ngakho-ke le ngxenye yokulahlekelwa kwamandla ayikona ukulahlekelwa kwevolumu.
