Qhov zais cia ntawm kev saib xyuas ntawm steel bar quenching thiab tempering ntau lawm kab

Hlau pas quenching thiab tempering ntau lawm kab yuav tsum muaj cov neeg ua haujlwm puv sijhawm ntawm lub sijhawm zoo tib yam. Cov neeg ua haujlwm yuav tsum nkag siab txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov khoom siv hluav taws xob, paub txog cov txheej txheem kev ua haujlwm, thiab kev paub txog kev saib xyuas dav dav. Thaum lub sijhawm ua haujlwm, lawv yuav tsum tau tshawb xyuas qhov ntsuas kub tsis zoo thiab lub suab nrov txawv txav. Txawm hais tias cov dej-txias qhov dej ntws tawm, seb lub qhov hluav taws xob cua txias ntawm txhua qhov channel tsis raug thaiv, txawm hais tias cov lus qhia ntawm ntau yam twj paj nruag yog qhov qub, thiab ua cov ntaub ntawv raws li cov kev cai, feem ntau xyuas cov thyristor qhov hluav taws xob sib npaug, qhov tsis kam-capacitance. Kev nqus cov kab hluav taws xob tsis zoo, thiab tsis tu ncua xyuas kev kho nrog oscilloscope Choj tso zis waveform, nruab nrab zaus tso zis waveform (xyuas seb lub kaum sab xis ntawm txhuas yog qhov qub), thiab inverter thyristor waveform (xyuas dynamic voltage equalization). Kuj xyuam xim rau kev ua haujlwm zoo ntawm kev tu txhua hnub. Tsis tas li ntawd, txhua txhua rau lub hlis mus rau ib xyoos lossis qhov kawg ntawm ib qhov project, yuav tsum tau ua raws li kev saib xyuas tsis tu ncua. Cov ntsiab lus yog raws li nram no.

1. Kev tu vaj tse sab hauv thiab sab nraud, suav nrog kev tu thiab tshuaj xyuas ntau yam ntawm cov pob qij txha, ntxuav cov relays, contactors, cov neeg sib cuag thiab cov hlau cores, hloov cov dej ntws, tshem tawm cov nplai ntawm cov dej txias, thiab hloov cov kav dej aging thiab deteriorated.

2. Tshawb xyuas cov rwb thaiv tsev thiab ntsaws lub capacitor rau cov roj to lossis hloov nws.

3. Ntsuas lub waveform ntawm txhua thyristor (ntawm lub teeb load, rated load thiab rated zog), thiab soj ntsuam seb nws cov yam ntxwv tau hloov.

4. Kev tshuaj xyuas tag nrho ntawm kev tswj xyuas Circuit Court thiab lub zog ua haujlwm, suav nrog kev ntsuas ntawm ntau theem ntawm waveform, ntsuas qhov ntsuas hluav taws xob, kev tshuaj xyuas theem hloov ntawm rectifier trigger pulses, thiab kev tiv thaiv kev ua haujlwm kev tshuaj xyuas kev ntseeg tau.

5. Ntsuas lub inverter tso zis waveform thiab xyuas seb cov npoo kev nyab xeeb puas tau hloov pauv loj.

6. Calibrate meters thiab tiv thaiv relays.

7. Ntsuas qhov hluav taws xob sib npaug sib npaug thiab tsis kam-capacitance absorption tsis kam ntawm txhua thyristor.

8. Tighten qhov txuas bolts ntawm cov khoom siv hluav taws xob thiab cov ntsia hlau los kho cov terminals thiab cov khoom siv.
