vharafu yekuyamura

Relief valve i hydraulic pressure control valve, iyo inonyanya kuita basa rekugara kudzvinyirira, kudzvinyirira mutemo, kuburitsa system uye kuchengetedza kuchengetedza mu hydraulic equipment. Muhuwandu hwepombi throttling regulation system, iyo pombi yehuwandu inopa kuyerera nguva dzose, kana iyo system inomanikidza inowedzera, kuyerera kwekuda kunoderedzwa, panguva ino vharafu yekuyamura inovhurwa, kuitira kuti yakawandisa idzokere kutangi, kuve nechokwadi kuti. iyo yekuyamura valve inlet pressure, kureva kuti, pombi yekubuda kwepombi inogara iripo. Ivhavha yekuyamura yakabatanidzwa mumutsara pakudzoka kwemafuta ekudzoka, uye kugadzikana kwezvikamu zvinofamba zvemashure ekumanikidzwa kwevhavha yekuyamura kunowedzera. Basa rekuburitsa rehurongwa nderekubatanidza solenoid valve ine diki yekuyerera inoyerera munhevedzano pachiteshi chekudzora chevhavha yekuyamura. Kana magineti emagetsi apihwa simba, chiteshi chekudzora chirikure chevharuvhu yekuyamura chinopfuura nepakati petangi remafuta. Panguva ino, pombi ye hydraulic inosunungurwa uye valve yekuyamura inoshandiswa sevhavha yekudzikisa. Basa rekuchengetedzwa kwekuchengetedza, kana chirongwa chiri kushanda zvakanaka, valve yakavharwa, chete kana mutoro unopfuura muganhu wakatarwa, kuwandisa kunozarurwa, uye kuchengetedzwa kwepamusoro kunoitwa, kuitira kuti kudzvinyirira kwehurongwa kurege kuwedzera.

Komatsu excavator Ivhavha inoshanda musimboti
Iyo ls valve yeKomatsu excavator inoreva kuyerera kwevhavhavha mu hydraulic system, iyo inogona kudzora kuyerera uye kudzvanywa kwemvura mu hydraulic system. Mumachera eKomatsu, iyo nheyo yekushanda yevharuvhu ye1s inonyanya kusanganisira zvinhu zviviri, zvinoti kuyerera kwekudzora uye kudzora kudzvinyirira.
1. Flow control
Kuyerera kunodzora tsoka kunodzora kuyerera kwemvura mu hydraulic system nekugadzirisa kuvhurwa kwevhavha ye1s. Apo Komatsu excavator inoda kugadzirisa kukurumidza kwe hydraulic cylinder, kuyerera kwemvura kunogona kudzorwa nekugadzirisa kuvhurwa kwevhavha ye1, kuitira kuti uwane kukurumidza kutonga kwe hydraulic cylinder. Iyo ls valve inodzora nzvimbo yekuyerera kwemvura nekugadzirisa gap pakati pe spool nechigaro, nekudaro ichidzora kuyerera kwemvura.
2. Kudzora kudzvinyirira
Kudzora kudzvinyirira kunoreva kudzora kushanda kwesimba re hydraulic system nekugadzirisa kudzvanywa kwe ls valve. MuKomatsu vanochera, iyo hydraulic system inoda kuchengetedza imwe dhizaini yekushanda kuti ive nechokwadi chekuti imwe neimwe hydraulic chikamu chinogona kushanda zvakajairika. ls valve inodzora kurasikirwa kwekumanikidza kwemvura inoyerera kuburikidza nepakati pevhavha nekugadzirisa kuvhurwa kwegomba rekunyorovesa, kuitira kudzora kushanda kwesimba rehurongwa.
