What are the reasons for the heating of the hydraulic press motor

The hydraulic press consists of two parts: the main engine and the control mechanism. The main part of the hydraulic press includes the body, the master cylinder, the ejector cylinder and the liquid filling device. The power mechanism is composed of oil tank, high pressure pump, low pressure control system, motor and various pressure valves and direction valves. Under the control of the electric device, the power mechanism realizes the energy conversion, adjustment and transmission through the pump and the cylinder and various hydraulic valves to complete the cycle of various process actions.

What is the cause of motor heating when using hydraulic press equipment? Jianlong hydraulic machinery Xiaobian to analyze:

1, overload, use the clamp meter to measure the normal electrical flow of the motor, if the electrical flow of the motor load is occasionally large and occasionally small, it may be the hydraulic pressure of the hydraulic press 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.

2. 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, our operation technicians can hear the sound.

3, the voltage fluctuation of the power grid becomes larger, and it will be immediately clear with a multimeter detection. Perhaps the hydraulic pump resistance is large and the motor and pump do not match with the motor insulation and the motor is reduced after disassembly for moderate reasons, but the motor heat of the four-column hydraulic press system is mostly caused by these reasons.
