Excavator Main Control Valve PC200-8 PC220-8 Kuchengetedza Valve 723-90-7601

Kusunungura vhezheni inoshanda nheyo: kusunungura vharuvhu rekuyamura kunoumbwa nevharo rekuzorora uye tarisa vharuvhu. Kana iyo kudzvanywa kwesiti inosvika pakuvandudza kwekuvhura kwevharuvhu rekuyamura, vharuvhu rekuyamura rakavhurwa uye pombi haina kutsigirwa. Kana kurudziro yehurongwa inodonha kusvika pakuvhara kudzvanywa kweiyo vheji yekuyamura, iyo yekuyamura vharuvhu inovhara uye pombi mitoro muhurongwa.
Iyo isina kuburitsa vharavha ndeye vhesi iyo inogona kugadzira iyo hydraulic pombi isina pasi pemamwe mamiriro. Iko kusunungura vharuvhu kunowanzove neValve vhezheni ine maviri-nzira-nzira vheji (kazhinji solenoid vharuvhu), iyo inoshandiswa kuisa iyo huru yekumanikidza kwehurongwa (pombi) kana chisiri kusunungurwa. Kana mafuta ekumanikidza azapwa (nenzira mbiri-mbiri-nzira yekuchinja shanduko), mafuta ekumanikidza anodzoserwa zvakananga kuzora zero, kuti azadzise hupenyu hwekutonga kwemafuta uye kuderedza kushandiswa kwesimba.
Ndezvechiitiko chakabatanidzwa chiuno mune chiuno. Kudzvinyirira kuderedza vharuvhu kunoshandiswa kugadzirisa kudzvinyirirwa kunodiwa neyectuator, iyo inoteedzana muchiuno uye kazhinji hazvigone kushandiswa muchinjinhi.

Ruzivo rwakatambanudzwa:
Rudzi rwekusunungura vharuvhu:
Pfungwa
Iyo yekuburitsa chiteshi uye kumanikidza vharuvhu kunoiswa zvakasiyana. Kana taburukirwa, ripo imwe neimwe iri muchinhu chisina kwayakarerekera, uye nemafuta kubva mumafuta anodzoserwa kumashure kuchiteshi chemafuta kuburikidza neVheni yega yega, uye iyo yekuisa mafuta chiteshi inomhanya nekudzokera kwese kwevharanda. Kana imwe yemagavariro iri kushanda (ndiko kuti, iyo inoburitsa ndima yekubviswa), iyo mafuta kubva mumafuta anopinda mutambi anodzora kubva pakudzoreredza kwevhudzi renzira, uye kudzvinyirirwa kunogumira nevharo yekumanikidza mune nhamba.
Kusunungura mhando
Iko kusunungura vharuvhu uye vharuvhu rekuchengetedza rakabatanidzwa kuti vagadzire vharuvhu-hwekumanikidza vharuvhu, iro riri kuturika vharuvhu uye vharuvhu rekuchengetedza, uye dzimwe nguva vharuvhu rakawandisa. Munguva yekuburitsa, ndima yekudzora yemafuta inopfuura nepakati pegwenzi yega yega, iyo yakafanana neyekuburitsa mafuta epasi.
