Excavator hydraulic pombi 585-9230 485-5747 proportional solenoid valve

Proportional solenoid valve imhando nyowani yeautomatic control actuator ine akawanda magadzirirwo emhando. Yakajairika ndiwo muviri mukuru uye vharafu yekutyaira. Iyo spool muvharuvhu yekutyaira inogadzirwa kuita imwe taper. Zvadaro, iyo yakasanganiswa yekutarisa yekuchinjisa mudziyo uye mudziyo wekutyaira unoshandiswa kudzora pakarepo huwandu hwemafuta, kuitira kuti uwane chinangwa chekudzora zvisina kunanga huwandu hwemafuta evhavha huru. Iyi sumo pfupi inotevera ichasuma basa reiyo proportional solenoid valve uye nheyo yekushanda yeproportional solenoid valve.

Hunhu hwe proportional solenoid mavharuvhu

1) Inogona kuona iyo isina nhanho gadziriso yekumanikidza uye kumhanya, uye kudzivirira iyo yekukanganisa chiitiko kana iyo inowanzo kuvhurika vheji inodzoserwa kumashure.

2) Remote control uye chirongwa chekudzora chinogona kuitika.

3) Kuenzaniswa nekudzora kwepakati, sisitimu inorerutswa uye zvikamu zvakaderedzwa zvakanyanya.

4) Inofananidzwa ne hydraulic proportional valve, idiki muhukuru, chiedza muhuremu, chiri nyore mukugadzirisa uye yakaderera mumutengo, asi kukurumidza kwayo kupindura kunononoka kudarika hydraulic system, uye inonzwawo kugadzirisa kuchinja.

5) Simba shoma, kupisa kwakadzika, ruzha rushoma.

6) Pachange pasina moto uye pasina kusvibiswa kwezvakatipoteredza. Haina kukanganiswa nekushanduka kwekushisa.

Nheyo ye proportional solenoid valve

Inobva pamusimboti we solenoid switch valve: kana simba rakagurwa, chitubu chinodzvanya simbi yesimbi yakanangana nechigaro, kuvhara vharafu. Kana iyo coil ichinge yasimbiswa, simba remagetsi rinobuda rinokunda simba rechirimo uye rinosimudza core, nekudaro richivhura vharuvhu. Iyo proportional solenoid valve inoita shanduko kune chimiro che solenoid on-off valve: simba rechirimo uye simba remagetsi rinoenderana pasi pechero coil ikozvino. Saizi yekoiri yazvino kana saizi yesimba remagetsi inokanganisa kurova kweplunger uye kuvhurwa kwevharuvhu, uye kuvhurwa kwevharuvhu (kuyerera mwero) uye coil ikozvino (chiratidzo chekudzora) zvine hukama hwakakodzera mutsara. . Direct acting proportional solenoid mavharuvhu anoyerera pasi pechigaro. Iyo yepakati inoyerera pasi pechigaro chevharuvhu, uye kutungamira kwayo kwesimba kwakafanana nemagetsi emagetsi, asi zvakapesana nechisimba chechirimo. Nokudaro, zvakakosha kuisa huwandu hwehuwandu hwehuwandu hunoenderana nehuwandu hwekushanda (coil current) mumamiriro ekushanda.
