Qhov tseeb tshuab kev ua tau zoo ntawm cov roj hmab foob yuav tsum tau tshawb xyuas:
1. sealing kev ua tau zoo
Sealing kev ua tau zoo yog qhov tseem ceeb tshaj plaws rau kev sib khi thiab cov khoom siv sib khi. Tus nqi ntawm cov dej xau ntawm lub nplhaib sealing yog ib qho qhia los ntsuas qhov kev sib khi ua haujlwm. Nws tsis yog tsuas yog lub foob uas cuam tshuam rau kev ua tau zoo ntawm kev sib khi, tab sis tag nrho cov khoom siv sealing tom qab ntau cov ntsaws ruaj ruaj tau teeb tsa thiab ua ke nrog ntau lub ntsiab lus ntawm lub sealing coupling nto.
2. Eccentricity kuj
Ntawm no yog qhov eccentricity tsis kam ua haujlwm tom qab txiav txim siab qhov sib txawv qhov tseeb thiab siv qee qhov eccentric load.
3. Kev sib txhuam (tsawg kawg ua haujlwm siab)
Kev sib txhuam quab yuam hauv kev siv tswv yim yog ntsuas los ntawm qhov tsawg kawg nkaus ua haujlwm siab. Rau reciprocating dynamic seals, qhov kev sib txhuam pib yog ntau dua qhov kev sib txhuam dynamic, uas yog qhov nyuaj dua thiab cuam tshuam rau kev pib ua haujlwm. Nws yog qhov ua tau los ntsuas qhov kev sib txhuam sib khi nrog qhov tsawg kawg nkaus pib ua haujlwm siab. Yog li ntawd, rau dynamic seals, qhov tsawg kawg nkaus ua hauj lwm siab yog feem ntau muab.
4. Kev ua tau zoo
Qhov kev ua tau zoo yuav tsum muaj cov khoom sib khi kom ua tau raws li cov kev xav tau saum toj no raws li kev ua haujlwm tau teev tseg thiab ua haujlwm rau qee lub sijhawm, yog li qhov ntsuas no tseem qhia tau tias qhov kev sib khi feem ntau tau txais qhov tsawg kawg nkaus ua haujlwm siab.
