Understand What Are the Electrical Spare Parts of Hydraulic Press

Electrical spare parts of hydraulic press play a vital role in its normal operation, involving control system, electrical drive and monitoring equipment. Common electrical spare parts include motors, contactors, relays, frequency converters, cables, power switches, button switches, encoders and sensors. Checking the running state of electrical spare parts regularly and replacing damaged parts in time can not only improve the reliability of hydraulic press, but also reduce the failure rate and ensure the smooth production.

Electrical Spare Parts: Controller

Programmable logic controller (PLC)

PLC is the core electrical spare part of the electrical control system of hydraulic press. It can control various actions of hydraulic press according to pre-written programs, such as pressure control, speed control, sequence control and so on. In complex hydraulic press operation, PLC electrical spare parts can accurately coordinate the actions of multiple actuators. For example, in the stamping hydraulic press for automobile parts, PLC can control the descending speed, stamping pressure and return speed of the punch to ensure that each stamping process meets the technological requirements.

When PLC breaks down, it is necessary to replace the whole module or some key components inside it, such as CPU (Central Processing Unit) chip and input/output (I/O) module. These spare parts can restore the normal function of PLC and ensure the automatic control of hydraulic press.

Industrial computer (industrial control computer)

The electrical spares of industrial computer are used for running monitoring software and data processing, providing an intuitive operation interface for operators and facilitating parameter setting, state monitoring and fault diagnosis of hydraulic press. In the production line of large-scale hydraulic press, the industrial computer can display the pressure, oil temperature, displacement and other parameters of the hydraulic press in real time and record the production data.

Electrical Spare Parts: Sensors

The electrical spare parts of the pressure sensor are used to measure the pressure in the hydraulic system and convert the pressure signal into an electrical signal and feed it back to the control system. For example, in the injection hydraulic press, the pressure sensor can monitor the cavity pressure in the injection process in real time to ensure the quality of plastic products.

Spare parts are mainly sensor probes and signal conversion circuits. When the probe of the sensor is damaged, it may lead to inaccurate pressure measurement; If there is a problem in the signal conversion circuit, the feedback electric signal will be abnormal, which will affect the judgment of the control system on pressure.

The spares electrical of displacement sensor are used to measure the displacement of piston or other moving parts of hydraulic cylinder, which is very important for accurately controlling the working stroke of hydraulic press. For example, in the hydraulic press of bending machine, the displacement sensor can accurately control the bending angle.

Its spare parts include induction head, signal line, etc. The damage of the sensor head will lead to the failure of displacement measurement, and the failure of the signal line will make the displacement signal unable to transmit normally.

Electrical spare parts of temperature sensor are mainly used to monitor the temperature of hydraulic oil. During the continuous operation of hydraulic press, the high temperature of hydraulic oil will affect the performance of hydraulic system, and the temperature sensor will transmit the temperature signal to the control system so as to take cooling measures.

Common spare parts are heat-sensitive components. When they are damaged, the temperature display will be abnormal or the cooling system cannot be triggered.
