Kev Saib Xyuas Thiab Disassembly/Assembly Of Self-Priming Pumps

Lub twj tso kua mis no muaj cov qauv yooj yim, txhim khu kev qha, thiab ruaj khov. Nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, nquag disassembly rau kev txij nkawm feem ntau tsis tsim nyog; kev txhaum tuaj yeem kho tau yooj yim thaum lawv tshwm sim.
1. Cov cheeb tsam tseem ceeb uas yuav tsum tau saib xyuas thaum lub sijhawm tu:
A. Rolling bearings: Cov no yuav tsum tau hloov thaum hnav mus txog ib theem tom qab ua haujlwm ntev.
B. Pem hauv ntej thiab nram qab foob nplhaib: Cov no yuav tsum tau hloov thaum hnav mus txog ib theem.
C. Mechanical seal: Feem ntau, lub tshuab foob yuav tsum tsis txhob muab tshem tawm rau kev tshuaj xyuas tshwj tsis yog tias muaj qhov tshwm sim. Yog hais tias qhov dej xau tseem ceeb tshwm sim ntawm qhov chaw nres nkoj hauv qab ntawm cov kabmob, lub tshuab foob yuav tsum tau muab tshem tawm thiab tshuaj xyuas. Kov cov khoom siv foob nrog kev saib xyuas thaum sib dhos thiab disassembly; xyuas kom cov chaw mating huv si, tiv thaiv daim iav- zoo li ua tiav ntawm qhov chaw nyob ruaj ruaj thiab rotating rings, thiab nruj me ntsis tsis txhob cuam tshuam los yog khob. Cov dej xau feem ntau yog tshwm sim los ntawm kev sib tw lossis khawb ntawm qhov sib txhuam ntawm daim iav -zoo li lub ntsej muag. Kev kho yog lapping lub ntsej muag kawg ntawm kev sib txhuam khub los kho daim iav tiav. Lwm qhov laj thawj ntawm kev xau yog kev teeb tsa tsis raug, deformation, lossis kev laus ntawm O- nplhaib; Nyob rau hauv tas li ntawd, lub nplhaib O- yuav tsum tau hloov thiab lub unit reassembled.
2. Pump disassembly thiab sib dhos ua ntu zus:
A. Tshem tawm lub cev muaj zog los yog txiav lub coupling.
B. Tshem tawm cov kabmob vaj huam sib luag; xyuas cov radial clearance nruab nrab ntawm lub impeller thiab lub nplhaib sealing pem hauv ntej, thiab xyuas lub impeller txiv ntoo kom looseness.
C. Tshem tawm cov txiv ntoo impeller, rub tawm lub impeller, thiab xyuas cov radial clearance ntawm lub impeller thiab lub nplhaib seal tom qab.
D. Loosen lub tshuab foob cov ntsia hlau, rub tawm lub nplhaib sib dhos, thiab tshuaj xyuas cov mating ntawm lub nplhaib tig thiab nyob ruaj ruaj ntawm lub ntsej muag nrog rau qhov xwm txheej ntawm O- nplhaib foob.
E. Unscrew lub coupling lub teeb screws thiab rub tawm lub coupling.
F. Tshem tawm cov kabmob kawg, tom qab ntawd tshem lub twj tso kua mis thiab cov kabmob.
G. Reassemble lub twj tso kua mis los ntawm kev ua raws li cov kauj ruam nyob rau hauv rov qab kev txiav txim.
