Pump efficiency yog nyob ntawm plaub yam: kua viscosity, iav clearance, siab sib txawv thiab twj rotating ceev. Qhov qis dua cov kua viscosity, qhov yooj yim dua nws yuav dhau los ntawm qhov muab seam. Nyob rau hauv lub twj tso kua mis Hairuite, lub seam no yog lub iav clearance. Lub siab sib txawv tuaj yeem tsav cov kua dej ntawm qhov ceev los ntawm qhov kev tshem tawm no yam tsis muaj kev cuam tshuam ntawm lub twj tso kua mis tig ceev. Yog li ntawd, qhov ntim sab hauv no ruaj khov nyob rau hauv ib lub sijhawm. Qhov tseeb ntawm cov kua dej sib npaug ntawm qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov tso tawm sab hauv.Yog tias lub twj tso kua mis nrawm, qhov ntws yuav nce ntxiv. Txawm li cas los xij, vim hais tias lub ntim ntim sab hauv yog ruaj khov, lub twj tso kua mis efficiency zoo dua. Ib yam li ntawd, yog lub twj tso kua mis ceev txo, lub twj tso kua mis efficiency txo.
Vim lub iav clearance, lub iav twj tso kua mis yog xaiv ib tug semi-kaw zoo tshem tawm twj tso kua mis. Thaum ua ntawv thov rau metering uas tsis muaj viscosity kua, qhov khiav thiab rotating ceev tsis muaj ib txoj kab ncaj nraim. Raws li rau tsawg dua 5 viscosity kua thiab nquag pib twj, peb pom zoo kom txhim kho ib-txoj kev li qub los yog hloov li qub ntawm lub qhov hluav taws xob.
