Excavator solenoid valve 25-220992 hydraulic twj tso kua mis proportional solenoid valve

Hom proportional valve
Kev faib tawm raws li kev tswj hwm lub valve yog hais txog kev faib tawm raws li kev hloov pauv hluav taws xob thiab tshuab hluav taws xob hauv kev tswj hwm lub valve ntawm proportional valve, thiab cov khoom siv hluav taws xob muaj ntau hom xws li proportional electromagnet, torque motor, DC. servo motor, thiab lwm yam.
(1) Electromagnetic hom
Hom electromagnetic hais txog lub proportional valve siv ib tug proportional electromagnet raws li ib tug hluav taws xob-mechanical conversion element, thiab proportional electromagnet converts lub input tam sim no teeb liab mus rau hauv lub zog thiab displacement mechanical teeb liab tso zis. Tom qab ntawd tswj lub siab, ntws thiab kev taw qhia tsis.
(2) Hom hluav taws xob
Hom hluav taws xob yog hais txog lub proportional valve siv DC servo lub cev muaj zog raws li lub tshuab hluav taws xob hloov hluav taws xob, thiab DC servo lub cev muaj zog yuav nkag mus rau cov teeb liab hluav taws xob. Hloov mus rau rotating motion ceev, thiab tom qab ntawd los ntawm cov ntsia hlau ntsia hlau, iav khib los yog iav CAM txo cov cuab yeej thiab hloov mechanism, tso zis quab yuam thiab hloov chaw, ntxiv kev tswj ntawm hydraulic tsis.
(3) electrohydraulic
Hom electro-hydraulic hais txog lub proportional valve nrog cov qauv ntawm lub cev muaj zog torque thiab nozzle baffle raws li kev tswj theem. Muab cov cim hluav taws xob sib txawv rau lub cev muaj zog torque, thiab tso tawm qhov hloov pauv los yog lub kaum sab xis los ntawm kev sib txuas nrog nws (qee zaum lub armature ntawm lub cev muaj zog yog lub baffle), hloov qhov kev ncua deb ntawm lub baffle thiab lub nozzle, kom cov roj ntws tsis kam. ntawm lub nozzle hloov, thiab ces tswj cov input parameters.
