Cov ntsiab lus yuam kev ntawm solenoid valve

1. Lub solenoid valve tsis ua haujlwm li qub tom qab muaj zog

Xyuas seb puas muaj qhov txuas tsis zoo hauv lub hwj chim cable → Reconnect lub cable rau lub connector.
Xyuas seb lub hwj huam mov voltage puas nyob rau hauv ± kev khiav hauj lwm ntau yam -→ ib txwm txoj hauj lwm ntau yam,
Seb lub kauj yog unwelded → re-welded,
Coil luv Circuit Court → Hloov coil,
Txawm hais tias qhov kev ua haujlwm siab sib txawv tsis tsim nyog → Kho qhov sib txawv ntawm qhov sib txawv → lossis hloov qhov tsim nyog solenoid valve,
Cov kua dej kub siab dhau lawm → hloov qhov tsim nyog solenoid valve,
Cov impurities ua rau lub ntsiab valve tseem ceeb thiab txav cov tub ntxhais ntawm lub solenoid valve daig → huv, yog tias lub foob puas lawm, hloov lub foob thiab nruab lub lim.
Cov kua viscosity loj dhau, qhov zaus siab dhau lawm thiab lub neej tau mus txog → hloov cov khoom.

2, solenoid valve tsis tuaj yeem kaw
Lub foob ntawm lub ntsiab spool lossis hlau txav core yog puas → Hloov lub foob,
Seb cov kua dej kub thiab viscosity siab dhau → hloov lub solenoid valve ntawm qhov chaw nres nkoj,
Cov impurities nkag mus rau lub solenoid valve spool lossis txav core → rau tu,
Caij nplooj ntoos hlav lub neej yog nce los yog deformed → hloov,
Choke qhov sib npaug qhov blockage → tu ncua sij hawm,
Lub sijhawm ua haujlwm siab dhau lawm lossis lub neej tau mus txog → hloov khoom lossis hloov kho cov khoom.

3. 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.
