Electromagnetic valve coil rau XGMA 815 excavator qhov chaw

Dab tsi ua rau electromagnetic coil corrosion

1.Lub high-frequency electromagnetic coil terminals yog tag nrho cov to vim tsis zoo sealing, thiab corrosion ntawm lub terminals muaj nyob rau hauv lub zoo theem, thaum lub electrode tsis zoo.

2.Yog li ntawd, nws tuaj yeem txiav txim siab tias qhov tsis zoo ntawm kev sib khi ntawm solenoid valve coil thiab dej seepage yog thawj qhov laj thawj rau corrosion ntawm lub davhlau ya nyob twg. Txawm li cas los xij, vim tias qhov kev ua haujlwm tsis zoo ntawm qhov chaw, nws yog qhov nyuaj kom tsis txhob muaj kev cuam tshuam ntawm cov thee ntawm lub kauj, yog li tsis muaj kev lees paub tias tsis muaj dej ntawm lub coil davhlau ya nyob twg.

3.Vim tias muaj ntsev ntawm lub davhlau ya nyob twg thiab ntsev hauv dej, nws ua raws li cov tshuaj electrolyte;

4.Yog li ntawd, cov tshuaj tiv thaiv galvanic tau nthuav tawm.

5.Txawm hais tias tus ncej tsis zoo, nyob rau hauv tus txheej txheem ntawm ntsaws rau hauv lub kaw electromagnetic coil, ib tug loj tus naj npawb ntawm cov khoom siv hluav taws xob ntws mus rau hauv tus ncej tsis zoo, thiab cov corrosion tam sim no nyob rau saum npoo ntawm qhov chaw nres tsheb tsis zoo poob mus rau xoom lossis zero. , uas inhibits qhov tseeb cov nyhuv ntawm lub davhlau ya nyob twg poob electrons, thiab ces lub corrosion ntawm lub davhlau ya nyob twg yog inevitable.

6.Qhov no tseem hu ua pipeline cathodic tiv thaiv nrog rau tam sim no ntxiv.

7.Raws li rau theem zoo, qhov xwm txheej yog qhov sib txawv, thiab nws dhau los ua kev mob siab rau anodic oxidation nyob rau hauv "Cathodic Protection Law of Pipeline at the Sacrifice of Anodic Oxidation".

8.Yog li ntawd, txawm hais tias lub cev lub cev ntawm tooj liab tsis yog tiag tiag, nws yuav corroded sai sai, thiab lub davhlau ya nyob twg yuav tawg, ua rau muaj teeb meem kaw.

9.Siv lub multimeter los ntsuas qhov resistor ntawm solenoid valve. Yog hais tias muaj ib tug resistor nyob rau hauv lub kauj, nws yuav tsum nyob ib ncig ntawm 100 ohms! Yog hais tias qhov infinite resistor ntawm lub kauj qhia tias nws tawg, lub solenoid valve coil tuaj yeem ua hluav taws xob thiab cov khoom hlau tuaj yeem muab tso rau ntawm lub relay, vim hais tias cov relay muaj cov khoom sib nqus los nyiam cov khoom hlau tom qab 220 volt electromagnetic coil txuas rau. Yog tias cov khoom hlau tuaj yeem nqus tau, nws qhia tau hais tias lub kauj yog qhov zoo, thiab qhov kev paub rov qab qhia tau tias lub kauj tawg. Qhov teeb meem nyuaj ntawm solenoid valve coil yog tias koj txoj haujlwm tsis raug ntawm kev ua haujlwm voltage lossis lub sijhawm ua rau overheating thiab hlawv, uas yog ntau dua. Tom qab ntawd, vim nws qhov tsis zoo, qhov kev sib txuas ntawm cov txheej txheem sab hauv coil tsis zoo kov, thiab tom qab ntawd qhov kev sib txuas yog luv luv vim muaj kev vibration tsis tu ncua lossis tam sim no ntws. Cov tshuaj feem ntau yog nyob ntawm cov khoom koj siv. Yog tias nws tsis raug kaw los yog riveted, nws tuaj yeem zoo ib yam li qhov sib pauv hloov kho qhov muag ntawm DC contactor. Txwv tsis pub, tsuas yog yuav muaj kev hloov pauv tag nrho.
