Yuav Ua Li Cas Lub Valve yuav tsum tau ua haujlwm thiab tswj xyuas thaum ua haujlwm

Lub hauv paus tswj xyuas thaum lub sijhawm ua haujlwm valve yog raws li hauv qab no:
① Khaws qhov chaw sab nraud thiab ua haujlwm ntawm lub valve kom huv si los tiv thaiv kev ncaj ncees ntawm cov xim valve. Lub valve nto, cov xov trapezoidal ntawm lub valve qia thiab valve qia txiv ntseej, lub valve qia txiv ntoo thiab zawv zawg ib feem ntawm kev txhawb nqa, nrog rau cov iav, cab iav thiab lwm qhov chaw yog ib qho yooj yim rau deposit ntau plua plav, roj thiab nruab nrab residue thiab lwm yam av, ua rau hnav thiab corrosion ntawm lub valve. Yog li ntawd, lub valve yuav tsum tau ceev kom huv si tsis tu ncua. Cov plua plav dav dav ntawm lub valve yog haum rau txhuam txhuam thiab compressed cua purging, thiab txawm tooj liab hlau txhuam yuav siv tau kom txog rau thaum cov txheej txheem nto thiab txuam nto qhia metallic luster, thiab cov xim pleev xim rau saum npoo qhia cov xim ntawm cov xim. Lub tshuab nqus dej yuav tsum muaj lub luag haujlwm tsawg kawg ib zaug ib zaug; Tsis tu ncua qhib lub tshuab ntxhua khaub ncaws thiab chav ntxiab hauv qab hlau ntsaws dej, lossis tshem tawm nws tsis tu ncua, kom tsis txhob thaiv lub valve nrog av.
② Khaws lub lubrication ntawm lub valve, lub trapezoidal xov ntawm lub valve qia txiv ntoo thiab zawv zawg ib feem ntawm kev txhawb nqa, txoj haujlwm bearing, lub meshing ib feem ntawm lub iav thiab cab iav pas nrig thiab lwm qhov chaw nrog cov kev ua ub no xav tau lubrication zoo kom txo tau. kev sib txhuam ntawm ib leeg thiab zam kev hnav ris tsho. Rau cov khoom uas tsis muaj roj khob lossis roj nozzles uas yooj yim puas los yog poob hauv kev ua haujlwm, lub lubrication system yuav tsum tau kho thiab dredging ntawm cov roj Circuit Court yuav tsum tau xyuas.
Lub lubricating qhov yuav tsum tau oiled tsis tu ncua raws li qhov xwm txheej tshwj xeeb. nquag qhib, qhov kub thiab txias li qub yog tsim rau refueling ib zaug txhua lub lim tiam mus rau ib hlis; Lub voj voog refueling ntawm li qub uas tsis nquag qhib thiab qhov kub tsis siab tuaj yeem ntev dua. Lubricants muaj xws li lub cev muaj zog roj, butter, molybdenum disulfide thiab graphite. Roj tsis haum rau qhov kub thiab txias li qub; Butter kuj tsis zoo haum, raws li nws melts ntawm kub kub thiab khiav tawm. Lub siab kub valve yog tsim rau ntxiv molybdenum disulfide thiab so graphite hmoov. Tawm mus rau sab nraud lubrication qhov chaw, xws li cov xov trapezoidal, cov hniav thiab lwm qhov chaw yog tias siv butter thiab lwm cov roj, nws yooj yim rau cov plua plav, thiab kev siv cov molybdenum disulfide thiab graphite hmoov lubrication tsis yooj yim rau cov kab mob. nrog plua plav thiab lubrication nyhuv zoo dua li butter, graphite hmoov tsis yooj yim rau coated ncaj qha, koj tuaj yeem siv cov roj me me los yog dej sib xyaw ua ke.
Lub ntsaws valve ntawm cov roj filling foob yuav tsum tau ntim cov roj thaum lub sijhawm teev tseg, txwv tsis pub nws yooj yim hnav thiab xau.
③ Khaws ob daim ntawv kom tiav thiab tsis zoo. Lub bolts ntawm flange thiab kev txhawb nqa yuav tsum ua kom tiav thiab tag nrho fastened. Tsis txhob plam lawv. Yog hais tias tus ceev ceev ntawm lub handwheel yog xoob, nws yuav tsum tau nruj me ntsis raws sij hawm kom tsis txhob hnav cov kev twb kev txuas los yog poob lub handwheel. Tom qab lub handwheel ploj lawm, nws tsis raug tso cai los hloov lub handwheel nrog lub phaj xoob, uas yuav tsum tau nruab rau lub sijhawm. Packing siab sib txawv tsis tso cai rau skew los yog tsis muaj qhov sib txawv preload. Yooj yim kom muaj kuab paug los ntawm nag, daus, plua plav thiab lwm yam av ib puag ncig, lub valve qia rau nruab ib lub hau tiv thaiv. Qhov ntsuas ntawm lub valve yuav tsum khaws cia kom zoo thiab raug. Valve foob, hau, pneumatic accessories, thiab lwm yam. yuav tsum ua kom tiav thiab tsis zoo. Lub tsho thermal rwb thaiv tsev yuav tsum tsis muaj dents thiab tawg.
Tsis tas li ntawd, lub valve tsis raug tso cai rau khob, txhawb nqa cov khoom hnyav lossis cov neeg sawv cev, kom tsis txhob qias neeg lub valve thiab ua rau lub valve puas. Tshwj xeeb, cov qhov rooj tsis yog hlau mesh thiab cam khwb cia hlau li qub yuav tsum raug txwv.
Tswj xyuas cov khoom siv hluav taws xob txhua hnub. Kev saib xyuas cov khoom siv hluav taws xob feem ntau tsis pub tsawg dua ib hlis ib zaug. Cov ntsiab lus ntawm kev saib xyuas yog: qhov zoo li yuav tsum huv, tsis muaj plua plav tsub zuj zuj, cov cuab yeej tsis muaj dej qab zib thiab roj; Lub sealing nto thiab taw tes yuav tsum ruaj thiab nruj. Tsis muaj qhov tshwm sim los; Lub lubricating ib feem yuav tsum tau refueled raws li cov kev cai, thiab lub valve qab lub txiv ntseej yuav tsum tau greased; Cov khoom siv hluav taws xob yuav tsum tsis zoo, tsis muaj qhov txhaum, tsis siv neeg hloov pauv thiab thermal relays yuav tsum tsis txhob mus, thiab qhov taw qhia lub teeb pom kev raug.
