Kev siv npauj npaim valve hauv kev ua haujlwm hauv qab no, kev pom zoo xaiv ntawm npauj npaim valve:
① Yuav tsum tau throttling, tswj thiab tswj qhov ntws;
② slurry media thiab xov xwm uas muaj cov khoom siv;
③ yuav tsum tau luv luv ntawm lub valve qauv;
④ yuav tsum tau qhib ceev ceev thiab kaw lub sijhawm;
⑤ Cov sij hawm sib txawv me me.
Nyob rau hauv ob txoj hauj lwm hloov, shrinkage ntawm cov channel, tsis tshua muaj suab nrov, cavitation thiab vaporization tshwm sim, ib tug me me npaum li cas ntawm to atmospheric abrasive media, koj muaj peev xwm xaiv npauj npaim li qub.
Nyob rau hauv tshwj xeeb tej yam kev mob ntawm throttling kev cai los yog sealing nruj, los yog hnav thiab tsim kua muag, tsis tshua muaj kub thiab lwm yam kev mob ntawm kev siv npauj npaim li qub, yuav tsum tau siv ib tug tshwj xeeb tsim ntawm hlau nyuaj foob nrog regulating ntaus ntawv ntawm peb eccentric los yog ob chav eccentric npauj npaim li qub.
Cov yam ntxwv ntawm npauj npaim valve
Npauj npaim valve sealing nplhaib cov khoom siv feem ntau yog siv roj hmab, yas, tab sis kev siv kub ua haujlwm tsawg; xws li kev siv cov hlau los yog lwm yam khoom siv kub-resistant los ua cov sealing nto, tuaj yeem siv rau qhov kub thiab txias.
Vim yog npauj npaim valve npauj npaim phaj txav nrog kev so, yog li feem ntau ntawm npauj npaim valve tuaj yeem siv rau kev tshaj tawm nrog cov khoom raug tshem tawm, raws li lub zog ntawm lub foob kuj tuaj yeem siv rau cov hmoov thiab granular media, nws yuav tsum tau muab sau tseg tias cov multi-theem hlau nyuaj foob npauj npaim valve tsis muaj feem xyuam rau tus mob no, vim hais tias ib zaug cov hais mus rau hauv lub non-metallic interlayer, nws yuav cuam tshuam rau sealing kev ua tau zoo, thiab txawm ua puas lub sealing nto.
Npauj npaim valve qauv ntev thiab tag nrho qhov siab yog me me, ceev qhib thiab kaw ceev, nyob rau hauv lub siab qhib, muaj ib tug me me kua kuj, thaum qhib mus txog 15 degree ~ 70 degree, thiab yuav ua tau yooj yim khiav tswj, npauj npaim valve qauv qauv yog lub feem ntau haum rau zus tau tej cov inch loj li qub.
