Why does the motor of the hydraulic press heat fault analysis

Let's analyze the reason why the motor of the hydraulic press will heat up the fault

First, the motor overload analysis, use the clamp meter to measure the normal electrical flow of the motor, if the electrical flow of the load operation of the motor appears large and small, it may be the hydraulic pressure is increased; If the current is relatively large when it is just started, and the current of the hydraulic system is too high when it does not start running, it means that the motor has a problem.

Second, check whether the bearing of the motor of the hydraulic system is stuck and the rotor is swept, because when there is such a failure, under normal circumstances, the operating technician can hear the sound.

Third, the voltage fluctuation of the external power grid becomes larger, and it is immediately clear when the multimeter is used to detect it. Perhaps the hydraulic pump resistance is large and the motor does not match the pump and the motor insulation drops and is installed after disassembly for moderate reasons.

Four, the oil press motor heating trip this situation mainly has the following points:

1. The pressure regulation of the relief valve of the hydraulic press is too high, and the overload is followed by the dull pump.

2, the relief valve spool stuck valve core center oil hole blockage or relief valve damping hole blockage caused by overpressure does not overflow.

3, the pump outlet check valve is installed back or the valve core is stuck and the pump is stuffy.

4. Motor failure.

The above points are the reasons why the motor of the hydraulic press heats up and the resulting impact.
