Cov ntsaws ruaj ruaj ob sab yog tsim los kom ntseeg tau tias cov ntsaws ruaj ruaj ua haujlwm tau zoo tshaj plaws. Cov ntsaws ruaj ruaj ob sab yuav luag tshem tawm cov kua lossis roj tawm hauv cov twj tso kua mis lossis cov khoom sib tov. Cov ntsaws ruaj ruaj ob sab muab kev nyab xeeb thiab txo qis kev ua raws li cov pa phem ntawm lub twj tso kua mis uas tsis ua tau nrog cov ntsaws ruaj ruaj ib leeg. Nws yog ib qho tseem ceeb uas yuav tsum twj lossis sib tov cov tshuaj txaus ntshai lossis tshuaj lom.
Ob chav mechanical seals feem ntau siv rau hauv cov khoom siv hluav taws xob, tawg, lom, granular thiab lubricating. Thaum siv nws, nws xav tau lub kaw lus sealing auxiliary, uas yog, cov kua cais tawm raug ntxig rau hauv qhov chaw sealing ntawm ob qho kawg, yog li txhim kho cov roj nplua nyeem thiab txias ntawm lub mechanical seal. Cov khoom twj tso kua mis uas siv ob chav mechanical seal yog: fluorine yas centrifugal twj tso kua mis lossis IH stainless hlau tshuaj twj tso kua mis, thiab lwm yam.
