Lub proportional control valve yog tswj valve uas txuas ntxiv thiab proportionally tswj qhov ntws, siab thiab kev taw qhia ntawm hydraulic system raws li cov khoom siv hluav taws xob, thiab nws cov zis ntws thiab siab tsis tuaj yeem cuam tshuam los ntawm kev hloov pauv.
Piv nrog rau cov khoom siv hydraulic zoo tib yam, proportional li qub muaj cov yam ntxwv hauv qab no:
1. Cov teeb liab hluav taws xob yog qhov yooj yim rau kev xa tawm, thiab tuaj yeem paub cov chaw taws teeb tswj tau yooj yim.
2. Nws tuaj yeem ua haujlwm tsis tu ncua thiab proportionally tswj lub siab thiab ntws ntawm hydraulic system, ua tiav kev tswj ntawm txoj haujlwm, ceev, thiab quab yuam ntawm tus actuator, thiab txo qhov cuam tshuam thaum hloov siab.
3. Txo tus naj npawb ntawm cov khoom thiab ua kom yooj yim rau cov roj Circuit Court.
Nyob rau tib lub sijhawm, kev siv thiab kev saib xyuas ntawm electro-hydraulic proportional li qub yog tib yam li cov khoom siv hydraulic. Lawv muaj kev tiv thaiv ntau dua thiab txhim khu kev qha ntau dua li servo li qub.
