I-Excavator solenoid valve 198-4607 i-hydraulic pump proportional solenoid valve

I-proportional solenoid valve iwuhlobo olusha lwe-actuator yokulawula okuzenzakalelayo enezinhlobo eziningi zokuklama. Okujwayelekile umzimba oyinhloko kanye ne-valve yomshayeli. I-spool ku-valve yomshayeli yenziwa i-taper ethile. Khona-ke, idivayisi edidiyelwe yokuqapha ukufuduka kanye nedivayisi yokushayela isetshenziselwa ukulawula umthamo wamafutha osheshayo, ukuze kufezwe inhloso yokulawula ngokungaqondile umthamo wamafutha we-valve eyinhloko. Isethulo esifushane esilandelayo sizokwethula umsebenzi we-proportional solenoid valve kanye nomgomo wokusebenza we-proportional solenoid valve.

Izici ze-proportional solenoid valves

1) Ingabona ukulungiswa okungenazinyathelo kwengcindezi nesivinini, futhi igweme into ethinta umthelela lapho i-valve yokushintsha evame ukuvuleka ihlehliswa.

2) Isilawuli kude nokulawulwa kohlelo kungenziwa.

I-3) Uma kuqhathaniswa nokulawula okuphakathi, uhlelo lwenziwa lula futhi izingxenye ziyancipha kakhulu.

I-4) Uma kuqhathaniswa ne-valve ye-hydraulic proportional valve, incane ngosayizi, ilula ngesisindo, ilula ngesakhiwo futhi inezindleko eziphansi, kodwa isivinini sayo sokuphendula sihamba kancane kakhulu kunesistimu ye-hydraulic, futhi iyazwela ekulayisheni izinguquko.

5) Amandla aphansi, ukushisa okuphansi, umsindo ophansi.

6) Ngeke kube khona umlilo futhi akukho nokungcoliswa kwemvelo. Akuthintwa kancane ukushintsha kwezinga lokushisa.

Isimiso se-proportional solenoid valve

Isekelwe esimisweni se-valve yokushintsha i-solenoid: lapho amandla enqanyulwa, intwasahlobo icindezela umgogodla wensimbi ngokuqondile esihlalweni, ivala i-valve. Lapho ikhoyili inikwa amandla, amandla kazibuthe aphumayo anqoba amandla asentwasahlobo futhi aphakamise umongo, ngaleyo ndlela avule ivalvu. I-proportional solenoid valve yenza izinguquko ezithile esakhiweni se-solenoid on-off valve: amandla asentwasahlobo namandla kazibuthe kagesi abhalansi ngaphansi kwanoma iyiphi ikhoyili yamanje. Ubukhulu bekhoyili yamanje noma usayizi wamandla kazibuthe kagesi buzothinta ukushaywa kwe-plunger nokuvulwa kwevalvu, futhi ukuvulwa kwevalvu (izinga lokugeleza) kanye nekhoyili yamanje (isignali yokulawula) inobudlelwano obuhle bomugqa. . Amavalvu e-solenoid asebenzayo aqondile ageleza ngaphansi kwesihlalo. I-medium igeleza ngaphansi kwesihlalo se-valve, futhi isiqondiso saso samandla siyafana namandla kazibuthe kagesi, kodwa okuphambene namandla asentwasahlobo. Ngakho-ke, kuyadingeka ukusetha isamba samanani okugeleza amancane ahambisana nobubanzi bokusebenza (ikhoyili yamanje) esimweni sokusebenza. Lapho amandla ecishiwe, i-valve ye-Drake liquid proportional solenoid iyavalwa (ngokuvamile ivaliwe).

Umsebenzi we-proportional solenoid valve

Ukulawulwa kwe-throttle yezinga lokugeleza kufinyelelwa ngokulawulwa kukagesi (yebo, ukulawulwa kwengcindezi kungabuye kufezwe ngezinguquko zesakhiwo, njll.). Njengoba ilawula i-throttle, kufanele kube nokuphelelwa amandla.
