E320B yekuchera vharafu yekuyamura 171-0030 E320 vharafu vharafu huru

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.

Relief valve, hydraulic pressure control valve. Iyo inonyanya kutamba basa rekugara kumanikidza kufashukira uye kuchengetedza kuchengetedza mu hydraulic michina. Constant pressure overflow effect: Muhuwandu hwepombi throttling regulation system, pombi yehuwandu inopa chiyero chekuyerera. Kana iyo system pressure ichiwedzera, kuyerera kudiwa kunoderera. Panguva ino, vharuvhu yekuyamura inovhurwa, kuitira kuti kuyerera kwakawandisa kudzoke kumashure kwetangi, kuve nechokwadi kuti iyo yekuyamura valve inlet pressure, ndiko kuti, pombi yekubuda kwepombi inogara iripo (gomba revhavha rinowanzovhurwa nekudzvinyirira kushanduka) . Izvo zvinhu zviri nyore kugadzira ruzha mumidziyo ye hydraulic zvinowanzoonekwa semapombi nemavharuvhu, uye mavharuvhu anonyanya kutungamirwa nemavharuvhu ekuyamura uye emagetsi anotungamira mavharuvhu. Pane zvinhu zvakawanda zvinounza ruzha. Ruzha rwevhavha yekuyamura ine marudzi maviri: velocity ruzha uye mechanical ruzha. Ruzha rwevelocity ruzha rwunonyanya kukonzerwa nemafuta vibration, cavitation uye hydraulic shock. Iro mechanical sound inonyanya kukonzerwa nekukanganiswa uye kuputika kwezvikamu muvharuvhu.
