Injection molding machine hydraulic pressure sensor failure causes and solutions

Injection molding machine hydraulic pressure sensor failure causes and solutions

Injection Molding Machine Hydraulic Pressure Sensor is a very important part of the injection molding machine, used to measure the pressure of the hydraulic oil circuit. In the working process of the injection molding machine, the failure of the pressure sensor will directly affect the working efficiency of the injection molding machine, and even lead to the seriousness of the injection molding machine can not work normally. Therefore, it is important to thoroughly investigate the causes of the failure of the pressure sensor of the injection moulding machine.

 

Causes of Failure Molding Machine Hydraulic Pressure Sensor

Incorrect mounting position:

The installation position of the pressure sensor has an important influence on the operating effect. If the pressure sensor is installed in an inappropriate position, it may cause the hydraulic oil circuit not to reach the actual value due to the size of the pressure. In this case, it is necessary to adjust the injection molding machine.

 

Faulty electrical connection

Injection molding machine hydraulic pressure sensor must transmit electrical signals when measuring the pressure of the hydraulic circuit. If there is a problem in the signal transmission process, it will cause the pressure sensor to fail. Therefore, the user must regularly check that the electrical connection of the pressure sensor is normal.

 

Failure assessment

If the molding machine hydraulic pressure sensor fails, the pressure value of the hydraulic oil circuit will not be properly measured, resulting in the injection molding machine not working normally. Users can avoid this failure by replacing or repairing the pressure sensor.

 

Solutions

Check and adjust the mounting position

To avoid improper installation of the pressure sensor, users must carefully check the installation manual of the injection molding machine and select the correct installation position according to the requirements. If in doubt, contact the manufacturer for advice.

 

Check the electrical connection

Users must check that the electrical connection of the pressure sensor is normal. If problems are found, check that the wiring is not disconnected or damaged, or contact the manufacturer for repair.

 

Replacing or Repairing the Pressure Sensor

If the plastic injection molding machine pressure sensor fails, you can replace or repair it. If replacing, make sure you use the same model as the original manufacturer and follow the installation instructions carefully. When repairing, you must find a professional manufacturer for repair.
