Sib piv nrog cov npauj npaim li qub, lub zog hluav taws xob uas siv hluav taws xob npauj npaim tuaj yeem tsis tsuas yog tswj tau nyob deb, tab sis kuj tseem muaj kev sib khi ruaj khov. Qhov tseem ceeb nyob hauv qhov tshwj xeeb ob chav eccentric qauv, uas tswj kev ruaj ntseg ntawm hluav taws xob npauj npaim valve, thiab kev sib khi tsis dhau qhov uas muaj ib txwm npauj npaim valve. Ib qho ntxiv, txoj kab uas hla ntawm lub pob tw ntawm lub npauj npaim hluav taws xob tau kaw nrog lub graphite compression sealing lub nplhaib kom tiv thaiv lub npauj npaim los ntawm kev xau. Ib qho ntxiv, vim tias lub npauj npaim hluav taws xob tau tsav los ntawm lub zog hluav taws xob, kev ua haujlwm tau zoo dua qub piv nrog phau ntawv tsav. Yog li ntawd, qhov ua tau zoo ntawm lub tshuab hluav taws xob txhim kho kev ua haujlwm tau zoo ntawm kev lag luam.
