Excavator solenoid valve 25-220994 hydraulic twj tso kua mis proportional solenoid valve

Tus qauv solenoid valve yog ib qho tshwj xeeb tswj solenoid valve, nws txoj cai tswj yog tswj kev qhib lub valve los ntawm sab nraud cov tswv yim hais kom ua teeb liab, thiaj li hais tias qhov kev tswj ntws thiab siab ib txwm tswj kom zoo ib yam li cov lus txib teeb liab. Nws siv "txoj haujlwm tawm tswv yim" thev naus laus zis, uas tuaj yeem hloov kho txoj haujlwm ntawm lub valve kom raug raws li lub suab tswj cov teeb liab, thiaj li ua tiav cov kev tswj kom raug, yog li nws tau siv dav hauv kev tswj hwm hydraulic kom raug.

Lub hauv paus ntsiab lus tseem ceeb ntawm lub proportional solenoid valve yog hais tias lub flow tswj teeb liab thiab tswj lub zog yog siv los ua lub zog qhov chaw ntawm lub electromagnetic coil, thiaj li hais tias lub electromagnet tswj qhov qhib ntawm lub valve, yog li qhov qhib ntawm lub valve yog roughly proportional rau lub valve. qhov loj ntawm qhov kev tswj cov teeb liab. Raws li qhov sib txawv khiav, txhua txoj haujlwm tswj muaj qhov sib txawv ntawm tus nqi, uas yog pub rov qab mus rau tus tswj ntws, tus tswj ntws tuaj yeem kho lub valve me ntsis raws li cov zis tawm ntawm tib qhov loj li qhov ntws ntawm no.
Yuav kom ua tiav cov kev cai tswj kom meej.

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

(2) Hom hluav taws xob

(3) electrohydraulic
