Excavator solenoid valve TM70402 24V hydraulic twj tso kua mis proportional solenoid valve

 Excavator electromagnetic nyem valve txhaum thiab kev daws teeb meem:

1. Qhov system siab hloov pauv

Cov laj thawj tseem ceeb ntawm kev hloov pauv siab yog:
① Cov ntsia hlau kho lub siab ua rau cov txiv ntoo xauv kom xoob vim kev co, ua rau lub siab hloov pauv;
② Hydraulic roj tsis huv, muaj plua plav me me, kom lub ntsiab spool zawv zawg tsis hloov pauv. Ua rau kev hloov pauv tsis tu ncua. Qee zaum lub valve yuav jam;
③ Lub ntsiab valve spool tsis du, ua rau lub qhov damping raug thaiv thaum nws dhau los;
(4) Lub conical nto ntawm lub ntsiab valve tseem ceeb tsis nyob rau hauv kev sib cuag nrog lub khob hliav qab ntawm lub rooj zaum valve, thiab nws tsis zoo grinded;
⑤ Lub qhov damping ntawm lub ntsiab valve tseem ceeb heev thiab tsis ua lub luag haujlwm damping;
Tus tsav valve kho lub caij nplooj ntoos hlav dabtsi yog khoov, ua rau muaj kev sib cuag tsis zoo ntawm lub spool thiab lub khob hliav qab, hnav tsis sib xws.
Txoj kev daws teeb meem:
① Ntxuav cov roj tank thiab cov kav dej tsis tu ncua, thiab lim cov roj hydraulic nkag mus rau hauv cov roj tank thiab cov kav dej;
(2) Yog tias muaj cov lim dej hauv cov raj xa dej, cov khoom lim thib ob yuav tsum tau ntxiv, lossis qhov pom tseeb ntawm cov khoom thib ob yuav tsum tau hloov pauv; Disassemble thiab ntxuav lub valve Cheebtsam thiab hloov cov roj hydraulic huv;
③ Kho lossis hloov qhov tsis tsim nyog;
④ Txo qhov damping aperture kom tsim nyog.

g, roj hmab nplhaib hnav thiab tsis hloov raws sijhawm.

Lub kaw lus siab tsis tuaj yeem nce ntxiv

Yog vim li cas 1:
① Lub qhov spool tseem ceeb damping yog thaiv, xws li lub rooj sib txoos ntawm lub ntsiab spool tsis huv, cov roj yog qias neeg dhau los yog sib dhos nrog cov khib nyiab;
② Kev sib dhos tsis zoo, kev sib dhos tsis zoo thaum lub sijhawm sib dhos, kev hloov kho tsis zoo ntawm qhov sib txawv ntawm cov li qub, lub ntsiab spool daig nyob rau hauv txoj haujlwm qhib, kev sib dhos tsis zoo;
③ Lub ntsiab spool reset caij nplooj ntoos hlav yog tawg los yog khoov, kom lub ntsiab spool tsis tuaj yeem rov pib dua.
Txoj kev daws teeb meem:
① Disassemble lub ntsiab valve tu damping qhov thiab rov sib dhos;
② Lim lossis hloov cov roj;
③ Tighten lub valve cap fastening ntsia hlau los hloov lub caij nplooj ntoos hlav tawg.

Ua rau 2: Tus tsav valve yog faulty
① Lub caij nplooj ntoos hlav kho tau tawg lossis tsis thauj khoom,
② Taper valve lossis steel pob tsis raug ntsia,
③ Lub taper valve yog tawg. Kev daws: Hloov cov khoom puas los yog hloov cov khoom kom rov ua kom lub valve ua haujlwm li qub.

Ua rau 3: Cov chaw taws teeb tswj chaw nres nkoj solenoid valve tsis tau siv rau (ib txwm qhib) lossis lub swb valve yog daig
Kev daws: Txheeb xyuas cov kab hluav taws xob kom pom tias cov khoom siv hluav taws xob txuas nrog; Yog hais tias ib txwm, nws qhia tau hais tias lub swb valve yuav daig, thiab cov faulty qhov chaw yuav tsum tau kho los yog hloov.
