Suab nrov thiab kev vibration
Lub suab nrov thiab kev vibration yog cov cim qhia ntawm cov kua dej ntws los yog cavitation hauv lub valve. Tej zaum koj yuav hnov cov hlau nplaum, hssing, lossis rattling suab. Cov teeb meem no tuaj yeem txo qhov kev ua haujlwm ntawm lub cev thiab ua kom cov khoom siv ua kom nrawm dua. Feem ntau ua rau muaj xws li cov roj paug, huab cua nyob rau hauv hydraulic system, los yog xoob installation. Kev lim roj tsis tu ncua thiab ua tib zoo sib dhos tuaj yeem txo cov teeb meem no.
-
Hluav taws xob los yog Solenoid Malfunction
Rau cov solenoid- ua haujlwm cov lus taw qhia li qub, hluav taws xob tsis ua haujlwm tuaj yeem tiv thaiv kev ua haujlwm zoo. Cov tsos mob muaj xws li tsis yog- cov valves teb lossis ua haujlwm tsis sib xws. Ua rau muaj xws li burnt- tawm solenoids, xoob xaim, los yog qhov hluav taws xob tsis raug. Ua kom muaj kev txhim kho kom zoo thiab zam kev siv lub sijhawm ntev ntawm solenoid coils tuaj yeem tiv thaiv cov teeb meem no.
Yuav Ua Li Cas Diagnose Directional Valve Issues
