Okubaluleke kakhulu ukunquma ukuthi kanjani auphawu lomshiniimisebenzi incike ebusweni bezimpawu eziphendukayo nezimile.Vala ubusoama-lapped ayisicaba kangangokuthi akunakwenzeka ukuthi uketshezi noma igesi igeleze kuwo.Lokhu kuvumela i-shaft ukuthi ijikeleze, kuyilapho uphawu lugcinwa ngomshini.Okunquma inani lesikhathi isigxivizo esizosigcina ukukhetha inhlanganisela yento yophawu efanele yohlelo lokusebenza.Ubuso bophawu oluqinile lwesevisi yokuhubhuka, i-Carbon Vs.I-Ceramic yamanzi alula (noma i-anti-freeze esimweni sezinhlelo zokusebenza zezimoto).Ikhabhoni vs.I-Silicon Carbide yezinhlelo zokusebenza eziningi zokunciphisa ukusetshenziswa kwamandla futhi inikeze impilo ende.Kuzinhlelo zokusebenza ezibucayi kuvame ukutuswa izigxivizo eziphindwe kabili zemishini.
Yonke enye indlela evuzayo ngaphakathi kwesigxivizo somshini ivinjiwe ngokusetshenziswa kwe-gasket, i-o-ring, wedge (Irabha, i-PTFE noma i-Flexible Graphite).Esinye isici esibalulekile se-mechanical pump seal yindlela yokulondoloza uphawu.Iziphethu (ezizodwa noma eziningi), izimbongolo zensimbi noma ama-elastomer acindezelwe nje asetshenziselwa ukunikeza amandla adingekayo ukuze kuqhubeke ukucindezela ubuso bophawu ndawonye.Umthwalo otholwa ubuso be-seal uklanywe ngomklamo wophawu.Ukukhethwa kokuthi yini engcono kakhulu kuncike ekushiseni, kanye nemvelo yalokho okuvalwa (i-viscosity, abrasiveness, isisindo (ingabe i-slurry?)).
Ama-Mechanical seal akhelwe amaphampu amaningi, ama-mixer nama-agitator asetshenziswa ekulungisweni.Ezimweni eziningi imiklamo iye yafakazelwa ukuthi iyasebenza eminyakeni eminingi yokusetshenziswa.Kwezinye izimpawu kufanele zakhelwe ukuthuthukisa izimfuno zezimboni.Idizayini yophawu oluyisisekelo olujikelezayo yobuso obushintshayo iyasebenziseka ukuze isebenze uhla olubanzi lwezinhlelo zokusebenza zokuvala kufaka phakathi ama-compressor.Izigxivizo zemishini ezijwayelekile zingafanelana nezidingo eziningi emazingeni okushisa angama-500 degrees F kanye nesivinini se-shaft sibe ngu-3600 RPM.Ukukhethwa kohlobo lophawu lwesibili kuvame ukunquma izinga lokushisa namakhono amakhemikhali ophawu.Inhlanganisela yezinto ezisetshenziswa ebusweni obuphendukayo nobumile ichaza ukumelana nokudubuka, kanye nokumelana namakhemikhali.Inhlanganisela yobuso be-Seal izophinde inqume inani lamandla asetshenziswa iphampu, i-mixer, i-agitator noma i-compressor.Ubuso be-seal bungalinganiswa ukuze buvumele ukuvaleka kwengcindezi ephezulu.Izigxivizo ezilinganiselayo zingavala izingcindezi ezingaphezu kuka-200 psi, noma zisetshenziswe ezigabeni eziningi zokucindezela okuphezulu noma izinsizakalo eziqinile zoketshezi.OEM mechanical sealsinganikezwa ukuze kuhlangatshezwane nezicelo ezifunwa kakhulu zezimboni uma kucatshangelwa ingcindezi, izinga lokushisa, isivinini noma uketshezi.
