Phau Ntawv Qhia Txog Kev Kho Mob rau YWZ9-300/E50 Electro-Hydraulic Nruas Nruas

Kev saib xyuas kom zoo ntawm YWZ9-300 / E50 ua kom lub neej ua haujlwm ntev, kev ua haujlwm ruaj khov, thiab kev nyab xeeb ua haujlwm. Hauv qab no yog ib qho kev npaj kho mob uas suav nrog kev kuaj xyuas txhua hnub, kev saib xyuas lub sijhawm, kev saib xyuas cov khoom tseem ceeb, thiab kev daws teeb meem:

1. Kev tu txhua hnub (ua ntej & Tom qab ua haujlwm)

Tsom ntsoov rau kev soj ntsuam ceev kom txheeb xyuas cov teeb meem pom tseeb thiab tiv thaiv tsis ua haujlwm thaum lub sijhawm ua haujlwm:

Tshawb xyuas cov roj to hauv E50 thruster, hydraulic hoses, thiab kev sib txuas. So kom huv si tam sim ntawd thiab ua kom xoob fittings; hloov cov ntsaws ruaj ruaj / hoses puas yog tias xav tau.

Tshawb xyuas lub nres lub cev, qib mechanism, thiab mounting bolts rau looseness, deformation, los yog corrosion. Rov kho cov bolts rau lub zog tshwj xeeb (220–250 N·m rau M16, 350–400 N·m rau M20) yog tias xoob.

Txheeb xyuas qhov kev sib tw nres thiab tso tawm. Xyuas kom tsis txhob muaj suab nrov txawv txav (xws li, squealing, sib tsoo) lossis jamming thaum ua haujlwm; xyuas tias lub thruster thawb pas nrig txuas / retracts linearly.

Saib xyuas lub nruas nres qhov chaw rau hnav, khawb, los yog overheating (discoloration qhia tias overheating). Ntxuav cov plua plav / cov khoom khib nyiab ntawm lub nruas thiab cov ntaub ntawv nrog cov txhuam kom qhuav (tsis txhob dej los yog roj).

2. Periodic Maintenance (Classified by Cycle)

2.1 Kev tu txhua lub lim tiam

Ntsuas tus nres tshem tawm (nruab nrab ntawm kev sib txhuam hauv ob sab phlu thiab nruas) nrog lub caliper. Qhov kev tshem tawm ib txwm yog 0.3-0.5 hli; siv lub tshuab tsis siv neeg hnav los kho yog tias nws siab tshaj 1 hli.

Tshawb xyuas cov kev sib txhuam hauv ob sab phlu rau hnav. Hloov cov ntaub yog tias qhov seem thickness tsawg dua los yog sib npaug li 5 hli (tsawg kawg hnav txwv) lossis yog tias muaj cov kab nrib pleb, roj paug, lossis hnav tsis sib xws.

Lubricate lub pob khawm, cov ntsiab lus pivot, thiab lub zog thawb lub pas nrig nrog siab - roj roj (kev ua haujlwm kub: -20℃txog 200 degree) kom txo tau kev sib txhuam thiab tiv thaiv kev sib tsoo.

2.2 Kev Kho Ib Hlis

Txheeb xyuas E50 thruster's hydraulic roj theem ntawm lub iav pom. Sau nrog ISO VG46 anti- hnav roj hydraulic yog tias qib qis dua "MIN" cim; Hloov cov roj yog tias nws pom huab, tsis muaj xim, lossis muaj cov impurities.

Tshawb xyuas lub thruster lub cev muaj zog thiab hluav taws xob sib txuas. Xyuas kom cov xaim yog nruj thiab rwb thaiv tsev, thiab lub thermal tiv thaiv (155℃trigger) ua haujlwm. Ntxuav cov plua plav ntawm lub cev muaj zog kom tsis txhob muaj cua sov.

Tshawb xyuas cov disc springs ' elasticity. Hloov cov springs yog tias lawv pom qhov deformation, qaug zog tawg, lossis tsis ua kom rov zoo tag nrho (muaj feem cuam tshuam rau braking torque).

2.3 Kev Kho Lub Plaub Hlis

Ntxuav lub nruas nres lub ntsej muag nrog cov ntawv xuab zeb zoo kom tshem tawm cov xeb, glazing, lossis kev sib txhuam cov khib nyiab. Tshawb xyuas lub nruas deformation (kawg runout Tsawg dua lossis sib npaug rau ± 0.3 hli, radial runout Tsawg dua lossis sib npaug rau ± 0.2 hli); hloov lub nruas yog tias deformation tshaj qhov txwv.

Tshawb xyuas hydraulic hoses rau kev laus, tawg, los yog bulging. Hloov cov hoses uas tau siv rau ntau tshaj 2 xyoos los yog qhia txog kev puas tsuaj (lub siab tawg ntau dua lossis sib npaug li 45 MPa).

Kuaj lub braking torque nrog lub torque meter. Kho lub E50 thruster lub hydraulic siab (12-16 MPa) yog tias lub torque nyob sab nraud ntawm 2000-3150 N·m.

2.4 Kev Kho Txhua Xyoo (Comprehensive Overhaul)

Tshem cov thruster cov roj hydraulic kom tiav, ntxuav cov roj tank thiab lim (10 μm precision), thiab rov ua dua tshiab ISO VG46 roj. Hloov cov roj lim lim yog tias nws txhaws lossis muaj kab mob.

Disassemble lub nres lub cev los tshuaj xyuas cov khoom siv sab hauv: hloov FKM cov ntsaws ruaj ruaj, tshawb xyuas cov kauj ruam rau kev khoov, thiab txheeb xyuas qhov tsis siv neeg hnav khaub ncaws ua haujlwm.

Ua kom muaj kev nyab xeeb tag nrho: simulate lub hwj chim tsis ua hauj lwm kom paub meej tias thaum muaj xwm ceev braking tsawg dua los yog sib npaug li 0.5 vib nas this, sim PLC interlock system (yog tias nruab), thiab xyuas kom muaj kev txwv kev hloov pauv (tso / hnav) ua haujlwm ib txwm.

3. Lub Ntsiab Tseem Ceeb Kho Kom Zoo

3.1 Friction Linings

Tsis txhob muaj roj lossis roj paug (txo kev sib txhuam coefficient); ntxuav tam sim ntawd yog tias muaj kab mob, thiab hloov yog tias nqus tau tshwm sim.

Hloov cov ntaub hauv ob sab kom ntseeg tau tias lub zog tsis sib xws; torque lub hauv ob sab phlu kho bolts rau 15-20 N·m.

3.2 E50 Electro-Hydraulic Thruster

Tsis txhob overload lub thruster (rated thrust: 50 kN, stroke: 50 mm). Xyuas lub valve nyem (max siab tsawg dua los yog sib npaug rau 18 MPa) kom tsis txhob muaj qhov hydraulic system overpressure.

Ntxuav lub thruster lub lim cua tsis tu ncua kom ua kom muaj cua zoo; hloov lub lim yog tias txhaws.

3.3 Nruas Nruas

Zam kev ua haujlwm siab ntev - qhov kub thiab txias (max deg kub tsawg dua lossis sib npaug li 200 degree) txhawm rau tiv thaiv lub nruas warping.

Khaws cov nruas cia rau hauv qhov chaw qhuav kom tsis txhob xeb; nruab nrog qhov nruab nrab kom zoo (kev sib txawv Tsawg dua lossis sib npaug ntawm ± 3 hli txheeb ze rau qhov chaw nres tsheb).
