Chimiro chekutanga uye nheyo yekushanda yevhavha yekuyamura Mu hydraulic transmission system, iyo hydraulic valve inodzora chiyero chemafuta inonzi pressure control valve, inonzi inonzi pressure valve. Izvo mavharuvhu aya akafanana ndeokuti anoshanda pamusimboti wekuti kudzvanywa kwemvura kunobata pane spool uye simba rechirimo zvakaenzana. Kutanga, chimiro chekutanga uye nheyo yekushanda yevhavha yekuyamura
Basa guru revhavha yekuyamura nderokupa nguva dzose kumanikidzwa kana kuchengetedza kuchengetedza kwe hydraulic system.
(A) basa uye zvinodiwa zvevhavha yekuyamura
1. Basa revhavha yekuyamura mu hydraulic system kuchengetedza kudzvinyirira nguva dzose ndiko kushandiswa kukuru kwevhavha yekuyamura. Inowanzo shandiswa mu throttling speed regulation systems, uye kuyerera kwekudzora mavharuvhu anoshandiswa kugadzirisa kuyerera mukati mehurongwa, uye kuchengetedza kudzvanywa kweiyo system kunogara kuripo. Mavharuvhu ekuyamura ekudzivirira kuwandisa anowanzo kunzi mavharuvhu ekuchengetedza.
2. Hydraulic system yekuyamura valve performance zvinodiwa
(1) High pressure yakarurama
(2) Kunzwa kwakanyanya
(3) Basa racho rinofanira kunge rakatsetseka uye risina kuzununguka uye ruzha
(4) Kana vharuvhu yakavharwa, chisimbiso chinofanira kuva chakanaka uye kubuda kunofanira kuva kuduku.
(2) Chimiro uye nheyo yekushanda yevhavha yekuyamura
Inowanzo shandiswa vharafu yekuyamura zvinoenderana nechimiro chayo uye yekutanga maitiro ekuita inogona kuderedzwa kune yakananga acting mhando uye mutyairi mhando mbiri.
1. Direct acting relief valve Iyo yakananga inoshanda yekuyamura vharuvhu inotsamira pamafuta ekumanikidza muhurongwa kuti aite zvakananga pane spool uye kuenzanisa simba rechitubu kudzora kuvhura nekuvhara chiito che spool. Ivhavha yekuyamura inoshandisa kudzvinyirirwa kunodzorwa sechiratidzo chekushandura kuwanda kwekumanikidzika kwechitubu, nokudaro kushandura nzvimbo yekuyerera yevhavha yevhavha uye chiyero chekuyerera kwechigadziro kuti chizadzise chinangwa chekugara uchimanikidza. Kana iyo system yekumanikidza inokwira, iyo spool inokwira, iyo inoyerera nzvimbo yevhavha port inowedzera, chiyero chekufashukira chinowedzera, uye kudzvinyirira kwehurongwa kunoderera. Mhedzisiro yakaipa yemhinduro yakaumbwa nechiyero uye kufamba kwe spool mukati mevhavha yekuyamura ndiyo musimboti weiyo inogara ichimanikidza kuita, uye zvakare ndiyo nheyo yekutanga yekushanda yeanogara achimanikidza mavharuvhu.
