Kev ceev faj rau kev saib xyuas ntawm High Pressure Common Rail Diesel Generator

Cummins diesel generator chaw tsim tshuaj paus qhia koj txog kev paub txog kev tu: kev ceev faj rau kev saib xyuas ntawm high voltage common rail diesel generator.

1. Kev siv txhua hnub

Lub high-pressure common rail diesel generator feem ntau yog nruab nrog preheater.Thaum nws pib nyob rau hauv qhov kub thiab txias ib puag ncig, lub preheating mus yuav tsum tau qhib ua ntej.Thaum lub teeb pom kev ntawm lub preheater qhib, nws qhia tias lub preheater pib ua haujlwm.Tom qab ib lub sij hawm ntawm preheating, lub tshuab hluav taws xob diesel tuaj yeem pib tom qab qhov ntsuas qhov ntsuas ua ntej tawm.Qhov taw qhia preheating kuj muaj lub tswb ua haujlwm.Yog hais tias lub preheating qhov taw qhia flashes thaum lub sij hawm ua hauj lwm ntawm ib tug ntau rail diesel generator, nws qhia tau hais tias lub diesel generator tswj qhov system tau ua tsis tiav thiab yuav tsum tau kho kom sai li sai tau.

Tsis txhob siv cov dej kub siab los yaug cov roj txhaj tshuaj ntawm cov tshuab hluav taws xob sib xyaw ua ke, vim tias tom qab cov dej nkag mus rau hauv lub tshuab hluav taws xob tswj, sensor, actuator thiab nws cov connector, lub connector feem ntau rusted, ua rau "mos txhaum" uas yog. nyuaj nrhiav hauv kev tswj hluav taws xob.

Lub tshuab hluav taws xob tswj, sensor thiab actuator ntawm high-voltage common rail diesel generator yog tshwj xeeb tshaj yog rhiab heev rau voltage.Txawm hais tias lub roj teeb muaj lub zog me ntsis, nws yuav cuam tshuam rau kev ua haujlwm ntawm lub tshuab hluav taws xob tswj.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum khaws lub peev xwm ntawm lub roj teeb kom txaus.Yog tias kev kho vuam tau ua tiav ntawm lub high-voltage common rail diesel generator, lub cable ntawm lub roj teeb yuav tsum tau disassembled, lub connector ntawm ECU yuav tsum tau txiav, thiab nws yog qhov zoo tshaj kom tshem tawm cov precision hluav taws xob tswj chav tsev.Hluav taws xob tswj chav nyob, sensors, relays, thiab lwm yam yog cov khoom siv hluav taws xob tsawg, thiab cov overvoltage generated thaum vuam yog yooj yim heev rau hlawv cov khoom siv hluav taws xob saum toj no.

Tsis tas li ntawd, kev ua haujlwm tom ntej tsuas yog tuaj yeem ua tiav tom qab lub tshuab hluav taws xob siab dav dav dav dav siv hluav taws xob tau kaw tsawg kawg 5min, txhawm rau tiv thaiv tus kheej raug mob los ntawm kev txhaj tshuaj roj siab.

2. Kev ntsuas tu

Lub tshuab hluav taws xob siab dav dav dav siv hluav taws xob muaj cov kev cai nruj heev rau cov khoom siv roj, thiab cov ntsiab lus ntawm sulfur, phosphorus thiab impurities tsawg heev.High quality lub teeb diesel roj thiab cav roj yuav tsum tau siv.Cov roj diesel tsis zoo yog ib qho yooj yim ua rau muaj kev cuam tshuam thiab hnav tsis zoo ntawm cov roj injectors.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tsis tu ncua tso dej thiab cov av hauv cov roj-dej separator, thiab tsis tu ncua los yog hloov cov lim dej thiab cov roj lim.Nyob rau hauv kev pom ntawm qhov zoo ntawm cov diesel siv los ntawm domestic generator teeb yog nyuaj rau tag nrho cov uas yuav tsum tau ntawm high-pressure common rail diesel generator, nws yog pom zoo kom siv tshwj xeeb diesel additives ntxiv rau cov roj tank thiab ntxuav cov roj mov. system tsis tu ncua.

Ua ntej disassembling cov roj txhaj tshuaj, los yog thaum lub nozzle ntawm cov roj txhaj tshuaj qhov chaw (xws li roj injector, roj xa yeeb nkab, thiab lwm yam) pom tias muaj stained nrog plua plav, nws raug nquahu kom siv cov khoom siv plua plav nqus cov plua plav ib puag ncig. , thiab tsis txhob siv lub tshuab nqus cua siab, lub tshuab nqus dej siab los yog ntxuav ultrasonic.

Lub tshuab hluav taws xob tu chav thiab cov cuab yeej yuav tsum tau ceev kom huv si kom tsis txhob muaj plua plav.Nyob rau hauv lub chav tsev tu lub tshuab hluav taws xob teeb tsa, cov khoom thiab cov fibers uas ua rau cov roj txhaj tshuaj tsis raug tso cai, thiab cov tshuab vuam, cov tshuab sib tsoo thiab lwm yam khoom siv uas tuaj yeem ua rau cov roj txhaj tshuaj tsis raug tso cai.

Cov khaub ncaws ntawm cov neeg ua haujlwm saib xyuas yuav tsum huv, thiab tsis pub nqa cov plua plav thiab hlau chips.Nws tsis raug tso cai hnav khaub ncaws fluffy kom tsis txhob muaj kuab paug rau cov roj txhaj tshuaj.Ntxuav tes ua ntej ua haujlwm tu.Kev haus luam yeeb thiab noj mov yog txwv tsis pub thaum lub sijhawm ua haujlwm.

3. Disassembly, cia thiab thauj cov khoom.

Tom qab lub high-pressure common rail diesel generating set khiav, nws yog txwv tsis pub disassemble lub high-pressure common rail txhaj system.Thaum tshem tawm lossis txhim kho cov roj xa rov qab cov yeeb nkab ntawm cov roj twj tso kua mis siab, quab yuam raws lub axial kev taw qhia kom tsis txhob khoov.Txhua lub txiv ntseej yuav tsum tau nruj rau lub zog torque thiab yuav tsum tsis txhob puas.Tom qab cov khoom siv roj tau muab tshem tawm, txawm tias lub sijhawm luv luv, lub hau tiv thaiv huv yuav tsum tau hnav tam sim ntawd, thiab lub hau tiv thaiv tuaj yeem raug tshem tawm ua ntej reassembly.Cov khoom siv ntawm kev siv hluav taws xob ntau lub tshuab hluav taws xob yuav tsum tau muab tshem tawm ua ntej siv, thiab lub hau tiv thaiv yuav tsum tau muab tshem tawm ua ntej sib dhos.

Thaum khaws cia thiab thauj cov khoom siv hluav taws xob ntau lub tshuab hluav taws xob, cov roj injector, cov roj twj tso kua mis siab sib dhos, cov roj tsheb sib dhos thiab lwm yam kev txhaj tshuaj yuav tsum hnav lub kaus mom tiv thaiv, thiab cov roj injector yuav tsum qhwv nrog ntawv roj.Cov khoom yuav tsum raug tiv thaiv los ntawm kev sib tsoo thaum lub sij hawm thauj mus los.Thaum noj thiab tso lawv, lawv tsuas yog kov lub cev ntawm qhov chaw.Nws yog txwv tsis pub kov cov pob qij txha ntawm lub qhov hluav taws xob thiab qhov hluav taws xob cov kav dej thiab cov qhov nozzle ntawm cov roj injector, kom tsis txhob muaj kuab paug rau lub siab-siab rail txhaj tshuaj system.
