Ukulahleka kwevolumu nokuvimbela ukulahleka kwephampu ye-slurry
Ukulahlekelwa kwevolumu i-centrifugal china slurry futha seal ring ukuvuza ukulahleka, ukulahlekelwa ibhalansi phakathi kwezikhungo kanye nezinga lokuvuza kokulahlekelwa kokuvuza.
Ukulahleka kokuvuza kwendandatho yophawu
Ku-inlet ye-impeller, indandatho yokuvala umsebenzi wepompo ye-china slurry, ngoba izindandatho zokuvala ezinhlangothini zombili kukhona umehluko wokucindezela, uhlangothi lokucindezela kwe-impeller outlet cishe luyingxenye eyodwa yokucindezela kwe-impeller inlet, ngakho-ke kuyoba khona njalo. ingxenye yoketshezi olusuka ku-impeller iye ekuvuzeni kwe-impeller inlet. Le ngxenye yoketshezi olutholakala emandleni we-impeller , kodwa uketshezi aluthunyelwanga, ngaleyo ndlela kuncishiswe inani lamanzi e-china slurry pump . Wonke amandla asetshenziswe ukunqoba ukuvuza kweringi ye-liquid seal endaweni yokumelana .
Ngokusobala, uma ubukhulu bendandatho yophawu bukhulu i-Dw , iba buthaka kakhulu ezinhlangothini zombili zomehluko wengcindezi, kuyanda inani lokuvuza. Kumaphampu e-china slurry, ukuze kwehliswe inani lokuvuza ukuze kuthuthukiswe ukusebenza kahle kwephampu ye-china slurry kufanele kuvunyelwe esimweni lapho igebe lendandatho yokuvala liyancipha. Ngokuvamile kulinganiselwa ukuthi ingqikithi yobubanzi bendandatho yophawu lokuvula ingu-0.002, njengoba i-Dw = 200 mm, imvume isiyonke ingu-0.40 mm. Lapho ihlanganiswa, indandatho yophawu ngokuyimfihlo ayinkulu kakhulu, ngaphandle kwalokho, inani lokuvuza lizokhula . Ezinye izinyathelo ezibalulekile ezisetshenziselwa ukukhulisa ukumelana kwendlela yendandatho yophawu lokunciphisa inani lokuvuza , ukwandisa ukumelana kwendandatho yophawu kwenziwa ??ye-maze, i-zigzag, njll. ukwandisa ukumelana endleleni .
Ukuvuza kwendandatho yophawu , futhi kwezinye izimo kungase kubangele ukuphazamiseka kwe-impeller inlet , ngakho umklamo kufanele wakhe indandatho yophawu ngokunengqondo .
Okwesibili, ukulahleka kokuvuza kwendlela yebhalansi
Eziningi ze-centrifugal china slurry futha, izikhungo zesici zokulinganisa i-axial thrust: njengezimbobo zokulinganisa, ukulawula ibhalansi, idiski yebhalansi. Njengoba kunezinhlangothi ezimbili zokulinganisa indlela yokuhlukanisa ingcindezi , kanjalo nengxenye yokuvuza koketshezi olusuka endaweni yokucindezela okukhulu kuya endaweni yokucindezela okuphansi . Cishe u-5% ukunciphisa imbobo yokuvuza kungalinganisa ukusebenza kahle kwephampu ye-china slurry. Ezikhungweni ze-disc zebhalansi, ukuvuza kubala u-3% wokugeleza komsebenzi, kodwa ezinye ze-high-pressure china slurry pump zikhulu kunalokhu; ukuze kuncishiswe ukulahleka kokuvuza kungancishiswa ibhalansi yediski ububanzi D ngaphandle kokuphazamisa isimo esiphikisayo ' .
Okwesithathu, ukulahlekelwa kokuvuza kwe-interstage
Kuphampu ye-slurry ye-volute ye-multi-stage yase-china, ukuhlukaniswa kwezinga ezinhlangothini zombili ze-pressure plate ranges, ngakho-ke kukhona ukulahleka kokuvuza, ngokuya ngohlelo lwama-ejensi ahlukene, izinga lokucindezela ezinhlangothini zombili zamapuleti e-spacer lingase libe eliyinhloko, eyesibili noma ephakeme , izigaba eziningi ziyahluka, bese kuba nokuvuza okunzima kakhulu phakathi kwezinga lokuhlukanisa, ngakho-ke lapha kusetshenziswa kakhulu phakathi kophawu olunyathelwe.
Ngaphezu kwalokho, esigabeni sephampu ye-china enezigaba eziningi, kukhona ukuvuza okuphakathi kwezigaba . Kodwa lokhu ukuvuza phakathi kwezinga okukhulunywe ngalo ngaphambili kuhlukile, ngoba le ngxenye yoketshezi ayivuzi nge-impeller , ayiyona yokulahlekelwa kwevolumu . Lapha, izinga lokucindezela elizungeze ipuleti lokuhlukanisa, elicindezelwe umthelela wokusabalalisa we-vanes wengxenye ye-impeller-side kanye negebe lokumunca (elilingana ne-centrifugal impeller) elidalwe. Endimeni yengcindezi ehlukile , ukuvuza kwezikhawu zeleveli yoketshezi ebhodini ngaphambi kokungena ku-impeller gap backlash , nangamavanes omhlahlandlela, iqabunga le-ABM (ama-inhalation guide vanes ) kanye nokubuyela phakathi kwegebe phakathi kwezinga, phinda inqubo. Yize izinga lokuvuza kwephampu ye-china enezigaba eziningi lingeyona eyokuncipha kwevolumu , kodwa kungukugeleza okuyindingilizi ukuya ekusetshenzisweni kwamandla kwephampu ye-china slurry. Ngaphezu kwalokho, ingxenye ye-liquid ngokusebenzisa i-vanes yomhlahlandlela, i-vane throat izobangela ukwehla kwesigaba sesiphambano esisebenzayo (okungukuthi, ukuvuza koketshezi kuthatha ingxenye ye-cross-section ), kuzokwandisa izinga lokugeleza lapha, okubangela ukulahlekelwa okwengeziwe kwe-hydraulic. . Ngokusho "kwesisekelo sokuklama iphampu ye-centrifugal china," incwadi emayelana : iphampu ye-china enezigaba eziningi, ngesilinganiso sokugeleza esingu-20 l / s, igebe eliphakathi kwezinga liyancipha lisuka ku-0.75 mm liye ku-0.25 mm, ukuvuza okuphakathi kwesiteji q ukwehla ngo-0.7 amalitha / isekhondi. ngenxa yokuncipha kwe-q, ukugeleza okudlula kuma-vanes kuyancishiswa, kunciphisa izinga lokugeleza kwe-vane emphinjeni, ukunciphisa ukulahlekelwa kwamanzi kuma-vanes, futhi ngenxa yokuthi q kunciphisa isivinini esihlobene se-impeller uketshezi kushiya i-slot yomhlahlandlela. uhlangothi luncishisiwe, ngaleyo ndlela kunciphisa ukulahlekelwa kwe-friction ye-disc impeller, ngakho-ke ukusebenza kahle kwepompo ye-china slurry kuthuthukiswa cishe ngo-5%.
