How to Adjust the Pressure Gauge of the Filter Press

The filter press pressure gauge usually refers to the indicator of the working pressure of the filter press. The adjustment of the pressure gauge mainly involves two aspects: one is to adjust the working pressure range of the system to meet the requirements of separation of different materials; the other is to monitor the working pressure changes of the system to ensure the normal operation of the filter press.

When adjusting the pressure gauge, it is usually necessary to determine the working pressure range based on the properties of the material, the model and specifications of the filter press, and the actual production needs. Generally speaking, the working pressure range of the filter press is between 0.4-1.2MPa, and the specific value needs to be determined according to the actual situation.

Specific Adjustment Steps

Close the feed valve of the filter press, start the hydraulic system, and keep the filter press in a pressure-maintaining state;
Observe the reading of the pressure gauge, and adjust the overflow valve or pressure-reducing valve, so that the reading of the pressure gauge meets the requirements;
Open the feed valve, let the material enter the filter press, observe the pressure changes, and adjust in time if there is any abnormality;
Repeat the above steps until the working pressure is stable within the required range.

Precautions for Adjusting the Pressure Gauge

Safety first: When adjusting the pressure gauge, ensure that the operator is familiar with the operating procedures and safety precautions of the filter press. During the adjustment process, avoid overpressure or excessive pressure fluctuations to avoid equipment damage or casualties.

Accuracy requirements: The reading of the pressure gauge should be accurate and reliable to ensure the accuracy of the adjustment. If the reading is abnormal or the error is large, the pressure gauge should be calibrated or replaced in time.

Consider the material characteristics: Different materials have different separation requirements, so the working pressure range should be reasonably selected according to the properties of the material (such as viscosity, particle size, density, etc.). For example, for materials with high viscosity, the working pressure can be appropriately increased to ensure a normal filtering effect.

Pay attention to equipment maintenance: When adjusting the pressure gauge, you also need to pay attention to the maintenance of the equipment. Regularly cleaning the filter press, checking whether the hydraulic system and pipelines are normal, and other measures can help improve the stability and service life of the equipment.

Accumulation of practical experience: In actual operation, operators need to continuously accumulate experience and flexibly adjust the pressure gauge according to actual conditions. Through the accumulation of practical experience, you can better grasp the performance characteristics and working rules of the filter press, and improve work efficiency and separation effect.

Causes and Solutions for Pressure Gauge Needle Skipping

Causes:

Friction between the pointer and the surface glass or scale
Bend of the central gear shaft
Damage at the meshing point of the two gears
The movable screw between the connecting rod and the fan gear is not flexible

Solutions:

Straighten the pointer and adjust the spacing
Straighten the gear shaft or replace the output shaft
Cleaning the gear
Thinning the connecting rod thickness

Conclusion

The adjustment of the pressure gauge of the filter press is an important part of ensuring the normal operation of the equipment and meeting production needs. In actual operation, attention should be paid to safety, accuracy, equipment maintenance and other issues, and practical experience should be accumulated according to actual conditions. If your filter press has abnormal pressure, you can describe the specific problem in detail, and I can help you solve it more accurately.
