Four methods for checking the failure of hydraulic pipe bending machine
1) Understand the operation status of hydraulic system of hydraulic pipe bending machine: whether the hydraulic system of the pipe bending machine is working normally; whether the hydraulic pump has abnormal phenomenon; the time and result of detecting the cleanliness of the hydraulic oil; the cleaning and replacement of the filter element; Whether the hydraulic components have been adjusted; whether the sealing components have been replaced; what abnormalities have occurred in the hydraulic system of the bending machine before and after the failure; in the past, what problems occurred in the system, how to remove them, etc., temperature rise, oscillation, crawling and The tightness of the joint determines whether the working condition of the moving parts of the hydraulic system of the bending machine is normal.
2) Look at the actual operation of the hydraulic system of the hydraulic pipe bending machine, and observe whether there are problems in the system pressure, speed, oil, leakage, oscillation, etc.
3) Listen to the sound of the hydraulic system of the bender, such as: impact sound; pump noise and abnormal sound; determine whether the hydraulic system works normally.
4) Touch the temperature rise, oscillation, crawling and the tightness of the joint to determine whether the working condition of the moving parts of the hydraulic system of the bending machine is normal.
