Mutyairi akashanda vharafu yekuyamura Migodhi michina yekuyamura vharafu RSDC-LAN

Mavharuvhu ekuyamura ekufambisa anowanikwa mune zvakasiyana siyana.Iyo yakajairwa-chikamu chetatu-yakaomesesa chimiro chekuyamura vharafu, iyo inoumbwa nezvikamu zviviri: pilot vharafu uye huru vharafu.

Iyo taper pilot vharafu, gomba rekunyorovesa (yakagadziriswa throttle hole) pahombe yevharuvhu uye kudzvanywa kunodzora chitubu pamwe chete zvinoumba mutyairi hafu-bhiriji chikamu chekumanikidza negative mhinduro yekutonga, iyo ine basa rekupa iyo huru nhanho yekumanikidza kumanikidza mushure mevharuvhu yekutyaira. kudzora kudzvinyirira kukamuri yepamusoro yevharuvhu huru spool.Iyo huru spool ndiyo muenzanisi weiyo huru control loop.Chiso chepamusoro chinoshanda sesimba rekuraira reiyo main spool, nepo kumucheto kwepasi kunoshanda sekumanikidza kuyera pamusoro peiyo huru loop uye kuita sesimba remhinduro.Simba rinoguma rinogona kutyaira spool, kugadzirisa saizi yechiteshi chekufashukira, uye pakupedzisira kuzadzisa chinangwa chekutonga nekugadzirisa kudzvanywa kweiyo inlet pressure P1.

YF mhando nhatu-chikamu concentric mutyairi wekuyamura vharafu chimiro Mufananidzo 1-(- taper vharafu (pilot vharafu); 2 - Cone chigaro 3 -vhavhavhavhavhavha; 4 - Muviri wevharuvhu; 5 - gomba rinonyorovesa; 6 - guru revharuvhu; 7 - Main chigaro 8 - chitubu chikuru chevhavha 9 - kudzvinyirira (pilot valve) 10 - kugadzirisa zviputi;

Hydraulic system cartridge valve zvakanakira:

①Hapana yakakwirira-kumhanyisa kudzosera maitiro:

iyi ndiyo inonyanya kutemwa nemusoro mune yakakwirira-simba hydraulic system.Nekuti iyo cartridge vharafu ndeye compact conical valve chimiro, vhoriyamu yekudzora idiki kana ichichinja, uye hapana "positive chivharo" pfungwa ye slide valve, saka inogona kuchinjika nekumhanya kukuru.Nekutora mamwe matanho ezvikamu zvechikamu chemutyairi uye kuchinjika kune yekuchinja nyika kutonga panguva yekuchinja maitiro, iyo inodzosera maitiro inogona kuderedzwa zvakanyanya panguva yekuchinja.

② Nekuvimbika kwakanyanya kwekuchinja:

iyo general cone valve yakaoma kukonzeresa chiito chakashata nekuda kwetsvina, kuderera kwekumanikidza kudiki, kupisa kudiki, uye spool ine chikamu chekutungamira kwenguva refu, iyo isiri nyore kubudisa skew yakanamatira phenomenon, saka chiito chakavimbika.

③Nekuti iyo cartridge logic valve yakamisikidzwa kumba nekune dzimwe nyika, ingave iri standard standard ISO7368, Germany DIN 24342 neChina (GB 2877 standard) yakaratidza saizi yekumisikidza yakajairwa pasirese, inogona kuita kuti zvikamu zvecartridge zvevagadziri vakasiyana zvishanduke, uye haisanganisi chimiro chemukati chevhavha.Izvi zvakare zvinopa iyo hydraulic valve dhizaini basa rekusiya yakakura scope yekusimudzira.
