Hydraulic motor application knowledge? When applying full load operation, pay attention to the operating torque of the hydraulic motor. Because the hydraulic motor start torque is lower than the rated torque, if ignored, will make the running organization can not work normally.
Because the mooring back pressure type of the independent variable motor of the hydraulic press is higher than the atmospheric pressure, the discharge pipeline of the motor only has an independent fuel tank, which cannot be connected with the return pipeline of the hydraulic motor.
Because the hydraulic motor of the crane always has oil seepage, so when the hydraulic motor is closed to brake, it will still appear relatively slow rolling. When braking for a long time, anti-rotation braking should be installed independently.
Common faults of hydraulic motors in the whole process of application, causes and how to solve XWM1 series hydraulic motors?
Invalid: the hydraulic motor cannot start, the working pressure increases, and the built-in relief valve is in poor position. After overhauling or replacing the relief valve, the working pressure will increase.
Cause: Bearing steel ball hydraulic motor negative pressure braking can not be removed, to remove the throttle valve blocking on the working pressure channel;
The negative pressure brake is not relieved, and the valve core is loaded up and down in reverse; When braking under negative pressure, friction or protection pieces are fixed; When braking under negative pressure, the brake piston rod is fixed;
The key position of the gate valve is not good: the valve core is stuck and the throttle valve is blocked.
Method: clear or replace the blocking of throttle valve; XSM7 series hydraulic motor valve core to the appropriate position; Replace the friction plate, protective plate; Repair or replace the diameter of the brake piston rod; Check, repair or replace the piston rod, rolling boots, sliding boots, pump gallbladder, separation plate, etc. Repair or replace.
Invalid: motor start is weak, set pressure is all right, but brake pedal is released late. Gate valve poor position, core stuck. The anti-brake equipment is removed, but the startup is slow, and the oil viscosity is too high in the work.
Cause: Negative braking is not completely relieved; Waste into the overflow valve; The roller is burned.
Methods: To investigate the plugging of throttle valve; Clean overflow valve, check or replace high pressure gate valve face; Check CA70 series hydraulic motors for overhaul or replacement of rolling parts.
