Ikhoyili ye-electromagnetic valve yezingxenye ze-excavator ze-XGMA 815

Yini ebangela ukugqwala kwekhoyili kagesi

1.Amatheminali amakhoyili amaza kagesi aphezulu wonke ayavuza ngenxa yokuvaleka kahle, futhi ukugqwala kwamatheminali kuba sesiteji esihle, kuyilapho i-electrode eyinegethivu injalo.

2.Ngakho-ke, kunganqunywa ukuthi ukuvaleka kahle kwekhoyili ye-solenoid valve kanye nokugeleza kwamanzi yizizathu eziyinhloko zokugqwala kwetheminali. Kodwa-ke, ngenxa yezimo zokusebenza ezimbi kakhulu lapho, kunzima ukugwema umthelela wamalahle kukhoyili, ngakho-ke asikho isiqiniseko sokuthi awekho amanzi endaweni yekhoyili.

3.Ngenxa yokuba khona kukasawoti endaweni yokugcina nosawoti emanzini, usebenza njengesixazululo se-electrolyte;

4.Ngakho-ke, ukusabela kwe-galvanic kuvezwa.

5.Mayelana nesigxobo esinegethivu, ngesikhathi sokuxhuma ikhoyili kagesi evalayo, inani elikhulu lezinto zikagesi ligelezela esigxotsheni esinegethivu, kanti ukugqwala kwamanje okungaphezulu kwetheminali enegethivu kwehlela kuqanda noma eduze kweqanda. , okuvimbela umphumela wangempela wetheminali yokulahlekelwa ama-electron, bese ukugqwala kwetheminali kungenakugwema.

6.Lokhu kubizwa nangokuthi ukuvikelwa kwe-pipeline cathodic nge-current eyengeziwe.

I-7.Ngokuqondene nesiteji esihle, isimo siphambene, futhi siba i-anodic oxidation ezinikele ku-"Cathodic Protection Law of Pipeline at the Sacrifice of Anodic Oxidation".

8.Ngakho-ke, ngisho noma izinto ezibonakalayo zethusi zingacacile, zizogqwala ngokushesha, futhi i-terminal izoqhekeka, okuholela ekuvaleni kwenkinga.

9.Sebenzisa i-multimeter ukukala i-resistor ye-solenoid valve. Uma kukhona okuphikisayo kukhoyili, kufanele kube ngu-100 ohms! Uma i-resistor engapheli yekhoyili ibonisa ukuthi yephukile, ikhoyili yevalve ye-solenoid ingafakwa ugesi futhi imikhiqizo yensimbi ingafakwa esikhungweni esidluliswayo, ngoba i-relay inezici kazibuthe ukuze ihehe imikhiqizo yensimbi ngemva kokuba ikhoyili ye-electromagnetic engu-220 volt ixhunyiwe. Uma umkhiqizo wensimbi ungamuncwa, kubonisa ukuthi ikhoyili yinhle, futhi ulwazi oluphambene lubonisa ukuthi ikhoyili iphukile. Inkinga enzima yekhoyili ye-solenoid valve ukuthi ukusebenza kwakho okungalungile ku-voltage yokusebenza noma isikhathi kuholela ekushiseni ngokweqile nasekushiseni, okuvame kakhulu. Khona-ke, ngenxa yekhwalithi yayo ephansi, indawo yokuxhuma ikhoyili yesakhiwo sangaphakathi ayithinteki kahle, bese indawo yokuxhuma ifinyezwa isikhashana ngenxa yokudlidliza okuvamile noma ukugeleza kwamanje. Isixazululo ngokuyinhloko sincike emikhiqizweni oyisebenzisayo. Uma ingavalwanga ngokuphelele noma ifakwe i-riveted, ingase ifane nekhoyili yokushintshanisa optical ye-DC contactor. Uma kungenjalo, kuzoba noshintsho oluphelele kuphela.
