Ukuhlaziywa kwengcindezi yengcindezi ye-valve valve nokuqedwa

Ukugeleza kwamanje nge-electromagnet ephelele kukhulu kakhulu, kepha ingcindezi namanje ayikabheki, noma ingcindezi edingekayo ayikwazi ukubhekwa ngalesi sikhathi ukumelana kwamakhoyili kwe-electromagnet, uma kungaphansi kwenani elishiwoyo, khona-ke umjikelezo wangaphakathi we-electromagnet coil aphukile; Uma i-electromagnet coil ukumelana ijwayelekile, khona-ke ukuxhumana kwe-amplifier ebanzi kunciphisiwe. Ngalesi sikhathi, i-electromagnet ebanzi kufanele ithathelwe indawo, futhi ukuxhumana kufanele kuxhumeke, noma ikhoyili ye-rewound kufanele ifakwe.

Lapho isinyathelo sokucindezela siyashintsha, ukuguquguquka kwengcindezi kwe-amplitude encane kuhlale njalo, futhi isizathu sokungazinzi kwengcindezi ebekiwe ikakhulukazi ukuthi kukhona ukungcola okuphakathi kwe-electromagnet kanye nengxenye eqondisayo (umhlahlandlela), ovimbela ukunyakaza komgogodla. Ngaphezu kwalokho, ingxenye eshelelayo ye-spool eyinhloko inamathele ngokungcola, okuvimbela ukunyakaza kwe-spool eyinhloko. Ngenxa yemiphumela yalokhu kungcola, i-hysteresis iyanda. Esikhundleni se-hysteresis, ingcindezi ayizinzile futhi ingcindezi iyashintshashintsha njalo. Esinye isizathu ukuthi ukugqokwa kwe-Iron Core kanye ne-pair ye-Magnetic Sleeve, igebe liyanda, kanye nengcindezi elungisiwe (ngenani elithile lamanje) alizinzile.

Ngalesi sikhathi, i-electromagnet ye-valve ne-applearef ingahlukaniswa ukuze ihlanze, futhi ukungcoliswa kwamafutha e-hydraulic kungahlolwa. Uma kwedlula iziqondiso, uwoyela kufanele uguqulwe; Ngokuthola ngokweqile okubangelwa ukugqokwa kwe-Iron Core, okuholela ekuphakameni kwamandla we-hysteresis, okuholela ekumisweni kwengcindezi engazinzile, ububanzi obungaphandle be-core core, ububanzi be-iron core kufanele bukhuphuke ukuze bulondoloze kahle umkhono wokuqondisa.

Impendulo yengcindezi isviggish futhi ingcindezi ishintsha kancane ngoba umoya ku-electromagnet engxenye awukhishiwe; I-orifice engaguquki kanye ne-orifice eyi-calve ephambili (noma i-arpass orfice) yokudonswa kwe-electromagnet core ivinjelwe ukungcola, kanye nokuhamba komongo we-electromagnet oyisisekelo kanye ne-main valve core kuvinjelwe ngokungadingekile; Ngaphezu kwalokho, kufakwa umoya ohlelweni, okuvame ukwenzeka lapho imishini isifakiwe bese iqala ukusebenza noma lapho umoya uxutshwe ngemuva kokuvalwa kwesikhathi eside.
