Reversing valve rau pneumatic system tsis ua hauj lwm

Cov kev ua txhaum ntawm lub thim rov qab valve muaj xws li: lub valve tsis tuaj yeem thim rov qab lossis rov qab ua haujlwm qeeb, cov pa xau, lub solenoid tsav valve muaj qhov tsis raug, thiab lwm yam.

(1) Lub reversing valve tsis tuaj yeem thim rov qab los yog qhov rov qab ua haujlwm qeeb, uas feem ntau tshwm sim los ntawm lubrication tsis zoo, lub caij nplooj ntoos hlav daig lossis puas, roj lossis impurities daig hauv qhov zawv zawg, thiab lwm yam hauv qhov no, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas. seb lub lag luam ntawm cov roj pos huab tshem tawm yog qhov qub thiab seb cov viscosity ntawm cov roj lubricating puas tsim nyog. Yog tias tsim nyog, hloov cov roj lubricating, ntxuav qhov zawv zawg ntawm qhov rov qab valve, lossis hloov lub caij nplooj ntoos hlav thiab thim rov qab.

(2) Tom qab siv rau lub sijhawm ntev, lub thim rov qab tuaj yeem hnav lub nplhaib tseem ceeb ntawm lub nplhaib thiab kev puas tsuaj ntawm lub qia thiab lub rooj zaum ntawm lub rooj zaum, ua rau cov pa tawm hauv lub valve, kev ua haujlwm qeeb ntawm lub valve lossis tsis ua haujlwm ntawm kev thim rov qab. . Lub sijhawm no, lub nplhaib sealing, qia thiab lub rooj zaum valve yuav tsum tau hloov, lossis hloov lub valve yuav tsum tau hloov.

(3) Yog hais tias lub inlet thiab tso qhov ntawm lub solenoid pilot valve yog thaiv los ntawm sludge thiab lwm yam sundries, lub sealing tsis nruj, lub movable hlau core yog thaiv, thiab lub Circuit Court yog faulty, thiab lwm yam., lub reversing valve yuav tsis tau. rov qab li qub. Rau thawj peb kis, ntxuav cov sludge thiab impurities ntawm tus tsav valve thiab cov tub ntxhais hlau txav tau. Circuit Court txhaum feem ntau muab faib ua kev tswj Circuit Court txhaum thiab electromagnetic coil txhaum. Ua ntej kuaj xyuas qhov txhaum hauv Circuit Court, tig lub pob qhov rooj ntawm qhov rov qab valve rau ob peb zaug kom pom seb lub thim rov qab tuaj yeem hloov cov kev taw qhia ib txwm nyob rau hauv qhov ntsuas huab cua. Yog tias nws tuaj yeem hloov cov kev taw qhia ib txwm, lub Circuit Court yog faulty. Thaum lub sij hawm soj ntsuam, qhov voltage ntawm lub solenoid kauj tuaj yeem ntsuas los ntawm qhov ntsuas kom pom tias qhov ntsuas hluav taws xob tau mus txog. Yog tias qhov hluav taws xob qis dhau lawm, ntxiv xyuas cov khoom siv hluav taws xob hauv kev tswj xyuas hluav taws xob thiab cov kev sib txuas mus ncig mus ncig. Yog tias qhov hloov pauv tsis tuaj yeem hloov pauv cov kev taw qhia ib txwm nyob rau hauv qhov ntsuas hluav taws xob, xyuas seb qhov txuas (plug) ntawm lub solenoid coil puas xoob lossis qhov sib cuag tsis muaj zog. Txoj kev yog tshem tawm lub ntsaws thiab ntsuas qhov ntsuas tus nqi ntawm lub kauj (feem ntau ntawm ntau pua ohms thiab ntau txhiab ohms). Yog tias tus nqi tiv thaiv loj dhau los yog me me, nws txhais tau hais tias lub solenoid puas thiab yuav tsum tau hloov.
