Ukulahleka komthamo kunye nokuthintela ukulahleka kwepompo ye-slurry
Ukulahleka komthamo we-centrifugal china slurry pump seal ring ukuvuza ukulahleka, ukulahleka kwebhalansi phakathi kwamaziko kunye nenqanaba lokuvuza kweelahleko zokuvuza.
A ukuvuza umsesane ilahleko
Kwi-inlet ye-impeller, ikhonkco lokutywina kwimpompo ye-slurry yase-china, ngenxa yokuba amakhonkco okutywina kumacala omabini kukho umahluko woxinzelelo, icala loxinzelelo lokuphuma kwe-impeller limalunga necala elinye loxinzelelo lwe-impeller, ngoko kuya kuhlala kukho. inxalenye yolwelo olusuka kwi-impeller outlet ukuya kwi-impeller inlet ukuvuza .Le nxalenye ye-liquid efunyenwe kumandla we-impeller, kodwa i-liquid ayithunyelwanga, ngaloo ndlela inciphisa inani le-china ye-slurry pump yamanzi.Onke amandla asetyenzisiweyo ukoyisa ukuvuza kweringi yetywina elulwelo kuxhathiso.
Ngokucacileyo, ubukhulu besangqa seringi yetywina Dw, kokukhona ihlwempuzekile kumacala omabini omahluko woxinzelelo, kokukhona ubuninzi bokuvuza.Kwiimpompo ze-china ze-slurry, ukwenzela ukunciphisa inani lokuvuza ukuphucula ukusebenza kwempompo ye-slurry yase-china kufuneka ivunyelwe kwimeko yokuvala i-gap yokutywina.Ngokuqhelekileyo uqikelelo lulonke oluqikelelweyo lwesangqa sesengi sesangqa esiyi-0.002, njenge-Dw = 200 mm, ukucocwa kukonke yi-0.40 mm.Xa zidityanisiwe, ikhonkco lokutywina ngokungqongqo lingabi likhulu kakhulu, ngaphandle koko, inani lokuvuza liya kwanda.Enye imilinganiselo ephambili esetyenziselwa ukunyusa ukuchasana kwendlela yokutywina yokunciphisa inani lokuvuza , ukwandisa ukuchasana komsesane wokutywina kwenziwa ?ye-maze, i-zigzag, njl. ukwandisa ukuxhathisa endleleni.
Ukuvuza kweringi yetywina , kwaye kwezinye iimeko kunokubangela ukuphazamiseka kwe-impeller inlet , ngoko ke uyilo kufuneka lube ngokufanelekileyo umsesane wokutywina .
Okwesibini, ilahleko yokuvuza kwendlela yokulinganisa
Kwiindawo ezininzi ze-centrifugal china slurry pump, i-axial thrust balancing feature amaziko: njengemingxuma yokulinganisa, ukulawula ukulinganisela, i-balance disc.Kuba kukho amacala amabini okulinganisa umlinganiselo woxinzelelo , kwaye ngoko ke inxalenye yokuvuza kwamanzi ukusuka kummandla woxinzelelo oluphezulu ukuya kwindawo yoxinzelelo oluphantsi .Malunga ne-5% ukunciphisa umngxuma wokuvuza kuya kulungelelanisa ukusebenza kwempompo yodaka lwaseChina.Kumaziko e-disc yebhalansi, ukuvuza kubangela i-3% yokuhamba komsebenzi, kodwa enye i-high-pressure china slurry pump inkulu kunale;ukuze kuncitshiswe ilahleko yokuvuza kungancitshiswa ibhalansi yediskhi yedayamitha D ngaphandle kokuchaphazela imeko echasene nobunzima ' .
Okwesithathu, ilahleko yokuvuza okuphakathi
Kwinqanaba le-multi-stage ye-china yepompo ye-slurry, isithuba somgangatho kumacala omabini oluhlu lweplate yoxinzelelo, ngoko ke kukho ilahleko yokuvuza, ngokuhambelana nokuhlelwa kwee-arhente ezahlukeneyo, inqanaba loxinzelelo kumacala omabini e-spacer plates ingaba yiprayimari, inqanaba lesibini okanye lesithathu, okukhona izigaba ezininzi zahluka, ngoko ke ukuvuza okuqatha phakathi kwenqanaba lesahlulelo, ngoko ke apha isetyenziswa ngokubanzi phakathi kwenqanaba letywina.
Ngapha koko, kwicandelo lempompo ye-slurry enamanqanaba amaninzi, kukho ukuvuza kwamanqanaba.Kodwa oku kuvuza phakathi kwenqanaba elikhankanywe ngaphambili lihlukile, kuba le nxalenye yolwelo ayivuzi nge-impeller, ayiyiyo yokulahleka kwevolumu.Apha, inqanaba loxinzelelo olujikeleze i-partition plate, lunyanzeliswa yimpembelelo yokusasazwa kwee-vanes zecandelo le-impeller-side kunye ne-gap yokufunxa (ilingana ne-centrifugal impeller) ebangelwa.Kwindima yoxinzelelo oluhlukileyo, ukuvuza kwezithuba zenqanaba lolwelo ecaleni kwebhodi ngaphambi kokungena kwi-impeller gap backlash, kunye ne-vanes yesikhokelo, igqabi le-ABM (i-inhalation guide vanes) kunye nokubuyela kwisithuba phakathi kwenqanaba, phinda inkqubo.Nangona inqanaba lokuvuza kwempompo ye-china yamanqanaba amaninzi ayiyoyelahleko yomthamo, kodwa kuqukuqelo olungqukuva ukuya kwimpompo yaseChina yokusetyenziswa kwamandla.Ukongeza, inxalenye yolwelo ngokusebenzisa i-vanes yesikhokelo, i-vane throat iya kubangela ukuba icandelo lomnqamlezo elisebenzayo liyancipha ( oko kukuthi, ukuvuza kolwelo kuthatha inxalenye yecandelo elinqamlezileyo ), kuya kwandisa umyinge wokuhamba apha, kubangela ilahleko ezongezelelweyo zehydraulic. .Ngokutsho kwe "centrifugal china slurry pump basis ," incwadi malunga : impompo ye-slurry ye-multi-stage china, kwinqanaba lokuhamba kwe-20 l / s, i-gap phakathi komgangatho wehla ukusuka kwi-0.75 mm ukuya kwi-0.25 mm, ubuninzi bokuvuza kwe-interstage q ukuhla kwe-0.7 ilitha / umzuzwana.ngenxa yokunciphisa i-q, ukuhamba okudlula kwii-vanes kuncitshisiwe, ukunciphisa izinga lokuhamba komqala we-vane, ukunciphisa ilahleko yamanzi kwi-vanes, kwaye ngenxa yokuba q ukunciphisa isantya esihambelanayo se-impeller ulwelo lushiya i-slot yesikhokelo. icala lincitshisiwe, ngaloo ndlela kunciphisa ukulahleka kwe-friction ye-disc ye-impeller, ngoko ke ukusebenza kwempompo ye-china slurry kuphuculwe malunga ne-5%.
