Kev sib piv cov txheej txheem - cov qauv thiab cov txheej txheem ua tiav ntawm lub pob valve pin yuav yooj yim heev, tab sis yog tias xav tau kev saib xyuas tom qab siv ntev, nws yuav nyuaj dua rau kev rhuav tshem lub qhov thiab lub phaj valve. Nws tsis yooj yim rau tshem tawm lub qia valve vim tias cov pins feem ntau ntaus yog piled thiab nias nrog lub zog nias. Lub pob valve tsis muaj pin yuav nyuaj heev hauv cov qauv thiab thev naus laus zis vim muaj ntau txoj hauv kev sib kis torque, tab sis kev saib xyuas tom qab thiab kev rhuav tshem yooj yim dua thiab yooj yim dua rau kev saib xyuas.
Kev sib piv ruaj khov - Cov npauj npaim valve nrog cov pins ruaj khov dua li cov uas tsis muaj pins vim lawv tau kho nrog cov pins. Cov qauv tsis muaj pins cuam tshuam rau qhov tseeb ntawm kev ua haujlwm vim yog kev hnav ntawm qhov chaw sib txuas ntawm lub qhov thiab lub rooj vag tom qab kev ua haujlwm ntev.
Kev Sib Piv Txog Kev Sib Txuas - Thaum kawg, cia peb saib qhov kev sib piv ntawm cov nyhuv sib txuas. Muaj ib zaj lus hais tias thaum siv lub npauj npaim valve nrog tus pin, cov khoom nruab nrab yuav nkag mus rau hauv qhov chaw uas tus pin raug pinned rau ntawm lub phaj valve thiab lub qia valve. Qhov txaus ntshai zais cia los ntawm qhov no yog tias tus pin raug corroded thiab tawg tom qab lub sijhawm ntev, ua rau lub valve tsis ua haujlwm, lossis teeb meem ntawm ejector xau lossis sab hauv xau hauv cov kav dej.
Hauv kev xaus lus, piv rau lub qhov rooj valve uas muaj pinned thiab lub qhov rooj valve uas tsis muaj pinned, txhua tus qauv tsim muaj nws tus yam ntxwv thiab qhov zoo, thiab peb tsis tuaj yeem hais tias qhov twg zoo dua. Tsuav yog peb xaiv cov khoom tsim nyog tshaj plaws rau peb cov peev nyiaj thiab peb cov xwm txheej ua haujlwm, nws yog cov khoom zoo rau peb.
