ZAXIS240-3 Reverse proportional solenoid valve excavator zvikamu hydraulic pombi

Electromagnetic proportional valve kushanda musimboti uye kuona:

Valve control yekuyerera inogona kukamurwa kuva marudzi maviri:
Imwe ndeye switch control: ingave yakavhurika zvizere kana kuvharwa zvakazara, mwero wekuyerera ungave wakakura kana diki, hapana nzvimbo yepakati, seyakajairwa magineti emagetsi kuburikidza nemavharuvhu, mavharuvhu ekudzosera emagetsi, electro-hydraulic reversing valves.
Imwe yacho inoramba ichidzora: chiteshi chevhavha chinogona kuvhurwa zvichienderana nekudiwa kwechero dhigirii rekuvhura, nekudaro kudzora saizi yekuyerera kuburikidza, mavharuvhu akadaro ane manyorero ekutonga, senge throttle mavharuvhu, asi zvakare anodzorwa nemagetsi, senge proportional. mavharuvhu, servo mavharuvhu.
Saka chinangwa chekushandisa proportional valve kana servo valve ndeye: kuwana kuyerera kwekutonga nemagetsi kutonga (zvechokwadi, mushure mekuchinja kwemaitiro kunogonawo kuwana kudzvinyirira kutonga, nezvimwewo), sezvo iri throttling control, panofanira kuva nekurasikirwa kwesimba, servo. vharafu nemamwe mavharuvhu akasiyana, kurasikirwa kwayo kwesimba kwakakura, nekuti inoda kumwe kuyerera kuchengetedza basa reiyo pre-stage control oil circuit.

Chimiro uye nheyo yekushanda ye solenoid valve

Iyo solenoid valve imhando yekuchinja inokwanisa kudzora mvura zvichienderana nekuchinja kweiyo voltage yedunhu rekutonga, uye inogona zvakare kugadzirisa kuyerera nekushandura saizi yevolti. Solenoid valve inowanzo shandiswa mumvura, gasi kuyerera kwekutonga, kutendeuka uye kudzvinyirira kutonga, chinhu chakakosha otomatiki chikamu.
Solenoid vharafu inonyanya kuumbwa nemuviri wevharuvhu, vharuvhu core, valve stem, solenoid coil, iron core, regulator uye zvimwe zvikamu. Muviri wevharuvhu chimiro chakabudikira, chine musoro wekubatanidza ne groove kana gomba, rinoshandiswa kubatanidza pombi yemvura, uye iyo electromagnetic coil uye regulator yakaiswa kunze: spool ndiyo chikamu chikuru chekutonga ikozvino, basa rayo. ndiko kubvuma kutonga ikozvino, kuitira kuti hunde yevhavha ifambe, nokudaro ichishandura dhigirii yekuvhura yevhavha; Hunde yevharuvhu ndiyo shaft inobatanidza core yevharuvhu nevhavha, iyo inoshandiswa kufambisa simba rekushanda rinodzorwa neelectromagnetic coil; Iyo solenoid coil ndiyo yakakosha mudziyo wekudzora kuyerera kweiyo solenoid valve, uye yayo inoshanda voltage uye simba rinogona kudzorwa zvinoenderana nezvinodiwa zvekutonga system mumhepo yedunhu. Iyo iron core ndeye magineti mune iyo electromagnetic coil, iyo inogona kuwedzera simba remagineti yecoil, nekudaro ichiwedzera kugona kwekuvhura nekuvhara; Iyo regulator chishandiso chekuona kuyerera kwemutemo, iyo inoziva chinangwa chekutonga nekushandura saizi yezvino.
