Ikhwalithi Enhle I-Solenoid Valve 121-1491 Izingxenye Zephampu Zokulawula I-VE ye-Caterpillar Excavator CAT320B 320C

Ama-valve e-Solenoid e-off state, ikhoyili ngeke ibe namandla, ngeke kube nokusetshenziswa kwamandla, ngakho-ke ikhoyili ngeke ishise. Futhi ngomfutho ophakathi namandla entwasahlobo kanye nezinye izici, noma ngenxa yamandla okumunca aphakathi nendawo akwanele ukubangela ukumuncwa kwensimbi okuguquguqukayo nokumile, kukhoyili iveza isimo esinamandla, ikhoyili izokhiqiza inani elithile lokumunca, futhi i-iron core eguquguqukayo izothola ukumuncwa kuka-electromagnetic kanye nomphumela wokudonsa unomphela uzibuthe womthelela wokunqoba amandla asentwasahlobo kanye nengcindezi ephakathi nendawo kanye nokumuncwa kwe-iron static, okuzoholela ekuvulekeni i-valve, kanye nembobo ye-valve yomzimba. Vula umlomo wevalvu womzimba wevalvu, ngaphansi kwesimo sokunqamula amandla ekhoyili, i-solenoid valve, i-static iron core ebonisa isimo sokumunca, kanye ne-solenoid valve ukuze ugcine i-valve evulekile ezinzile. Ku-valve ye-solenoid yokuvala, ikhoyili izokhiqiza i-reverse yamanje, inkambu kazibuthe ekhiqizwe inkaba yensimbi ehambayo ibheke kolunye uhlangothi, ngaphansi kwendima yokunyanyiswa kobungqingili izokwehlisa ngempumelelo umgogodla wensimbi onyakazayo ku-iron emile. Umnyombo wokukhanga, okuholela ekuhlukaniseni ama-cores ensimbi ahambayo futhi amile, ukuze i-valve ivalwe umlomo we-valve womzimba.

Ukuze uvikele ukusebenza okuzinzile kwe-valve ye-solenoid, ukugwema ngokuphumelelayo ukuvela kokushisa kwekhoyili nezinye izinkinga, emsebenzini we-valve ye-solenoid kufanele inake ukugcinwa kokuphathwa, ngokusebenza, ukwenza amaphuzu alandelayo:

Okokuqala, ku-valve ye-solenoid yomshayeli, ngokusho kwezidingo zokucaciswa ukuhlola ingcindezi ehlukile epayipini, uma ingcindezi yokuhlukanisa incane kakhulu izobangela ukuthi i-solenoid valve ayikwazi ukusebenza kahle. Uma ingcindezi yokuhlukanisa incane kakhulu, kufanele sikhethe ama-valve e-solenoid asebenza ngokuqondile. Uma ukucindezela okuhlukile kukhulu kakhulu, kuzoholela ekuphakameni kwenani lokuklama kwe-valve ye-solenoid, ayikwazi ukuqinisekisa ukusebenza kwayo okujwayelekile, ngalesi sikhathi ukusebenzisa i-valve ye-solenoid ephezulu.

Okwesibili, izimo eziningi ngaphansi kwe-valve ye-solenoid zifakwe ngokuvundlile, uma uhlangothi lokufakwa luzokwenza ukuthi i-valve ivalwe ngokuqinile futhi ibangele ukuvuza kwangaphakathi nezinye izinkinga. Kulokhu, gwema ukukhweza ohlangothini ngangokunokwenzeka.

Okwesithathu, uma i-valve ye-solenoid isikhathi eside, izoholela ku-piston kanye nesihlalo se-valve phakathi kokubekwa uphawu akwanele, esimweni esinjalo kufanele siphinde sigaye indawo yokubeka uphawu ye-piston, bese isihlalo se-valve sigaya.

Okwesine, emsebenzini wephrojekthi, ukuhlola i-valve ngaphambi nangemva kwe-gauge ye-pressure gauge, ukuqinisekisa ukuthi ukucindezela kokusebenza akuphakeme kunenani lokucindezela elilinganiselwe, ingcindezi yokusebenza ehlukile kufanele ilawulwe ebangeni elifanele lokucindezela okulinganiselwe okulinganiselwe. , emsebenzini wengcindezi iphakeme kunengcindezi ehleliwe noma iphakeme kunengcindezi ehlukanisiwe elinganiselwe, kufanele simise ukusetshenziswa kwama-valve e-solenoid, futhi ngokuhamba kwesikhathi, ngaphambi nangemva kwama-valve okwenziwa ngesandla, ukugwema i-solenoid valve. ukuqhuma nokuvuza nezinye izindaba.

Okwesihlanu, ngemva kokufakwa kwamavalvu e-solenoid, ukwenza isenzo sokuhlola abezindaba izikhathi eziningana, ngemva kokunquma okujwayelekile kwawo ngaphambi kokuba asetshenziswe.

Okwesithupha, ukuhlanza ama-angstroms aphansi, ukucutshungulwa ngesikhathi ku-valve ngaphakathi nangaphandle kanye nasendaweni yokumunca izikhali endaweni engcolile eyinsalela, ukugwema ukulimala endaweni evalayo.

Okwesikhombisa, i-valve ye-solenoid ekusebenzeni kokumisa ukuvala i-valve ngaphambi kwe-valve manual, isikhathi eside ngaphandle kwe-valve ye-solenoid bese iphinda isebenze isikhathi, kuyadingeka ukuhlola ngokuvumelana nezinkambiso, ekushintsheni okujwayelekile isicelo esinengqondo.
