The Reason Why The Filter Plate Cannot Be Opened After The Filter Press Is Compressed

There may be some problems with the use of the filter press, such as the filter plate cannot be opened after being tightened. There are many reasons for this phenomenon, which may be problems in the control system, the compressing system and other aspects. It is necessary to gradually find the cause before taking the previous measures to solve it. The following are some possible causes of this phenomenon and the corresponding solutions.

Overcompacted Materials

The materials are over-compacted during the processing process, making them difficult to loosen. This may be caused by the properties of the materials (such as viscosity), excessive pressure on the filtered materials, or improper operation.

Solution: Adjust the compression degree of the filter material. If the material is too compacted, you can adjust the compression force appropriately and reduce the compression pressure.

Hydraulic System Problems

Insufficient oil in the hydraulic system will cause the filter press not to operate properly, especially when compressing and loosening. In addition, blockage of the hydraulic oil circuit will prevent the oil pressure from being transmitted normally, thus affecting compressing and loosening. Damage to the hydraulic pump or control valve may also cause the system not to operate normally, affecting the tightening or loosening of the filter press.

Solution: First, check the oil level in the hydraulic oil tank and add hydraulic oil to the normal range. Secondly, check the oil circuit of the hydraulic system and clean or replace blocked parts. Finally, the hydraulic pump and valves must be checked and repaired or replaced if necessary.

Cloth Blockage or Damage

The filter cloth of the filter press may become clogged, or the material may adhere, causing the filter press equipment to get stuck during operation.

Solution: Check the filter cloth or filter plate for solid particles, sticky substances, damage, or aging. If so, clean or replace them in time to reduce adhesion and make the filter plate easier to open.

Failure of the Compression System

The compression plate or other moving parts may become stuck due to long-term use or poor lubrication, which may cause the filter plate to be unable to open.

Solution: Check the movement of the compression plate and clean and lubricate the tracks to ensure the parts move smoothly.

Control System Failure

A control system failure, such as circuit board damage or abnormal control signal transmission, can also cause the filter press to fail to operate normally.

Solution: Check the control panel, line connections, and sensors to confirm whether there are any faults and repair or replace the faulty parts on time.

A Pressure Sensor or Setting Problem

A damaged pressure sensor will cause the system to be unable to detect the correct pressure value, thus affecting the loosening operation of the filter press. If the pressure setting value is too high or too low, it may also affect the normal operation of the filter press.

Solution: Check the condition of the pressure sensor and calibrate or replace it if necessary. Also, check and adjust the pressure setting to ensure it is within a reasonable range.

Based on the analysis of the above possibilities, you can basically determine the problem and help you solve it. If the problem still cannot be solved, you can consult a professional technical engineer or consult your supplier.
