Excavator solenoid valve TM70202 24V hydraulic twj tso kua mis proportional solenoid valve

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm solenoid valve:

Lub solenoid valve siv lub tshuab hluav taws xob los thawb lub valve tseem ceeb los tswj cov kev taw qhia ntawm cov cua compressed, yog li tswj cov kev taw qhia ntawm pneumatic actuator hloov.

Nws qhov zoo dua yog kev ua haujlwm yooj yim, yooj yim kom ua tiav cov chaw taws teeb tswj.
Electromagnetic directional valve raws li cov kev xav tau sib txawv tuaj yeem ua tiav ob txoj hauv kev, ob txoj kev tsib thiab lwm yam.

Cov electromagnet siv los khiav lub solenoid valve tau muab faib ua AC thiab DC:
1. Qhov voltage ntawm AC electromagnet feem ntau yog 220 volts. Nws yog tus cwj pwm los ntawm lub zog pib loj, lub sijhawm luv luv thiab tus nqi qis. Txawm li cas los xij, thaum lub valve core yog daig lossis qhov nqus dej tsis txaus thiab cov tub ntxhais hlau tsis tau nqus, lub tshuab hluav taws xob yog qhov yooj yim los hlawv vim tam sim no ntau dhau, yog li kev ntseeg tau ntawm kev ua haujlwm tsis zoo, cuam tshuam ntawm kev ua, thiab lub neej. qis.
2, DC electromagnet voltage feem ntau yog 24 volts. Nws qhov zoo yog kev ua haujlwm txhim khu kev qha, tsis yog vim cov spores daig thiab hlawv tawm, lub neej ntev, me me, tab sis lub zog pib me dua li AC electromagnet, thiab thaum tsis muaj DC fais fab mov, yuav tsum muaj cov khoom siv kho kom zoo.

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.
