Russian Why Does the Hydraulic Automatic Filter Press Not Maintain Pressure?
The hydraulic automatic filter press is a commonly used filtering equipment that uses a hydraulic system to squeeze and separate filter materials. However, when using a filter press, sometimes the pressure is not maintained. This article will discuss the reasons why the hydraulic automatic filter press does not maintain pressure and the corresponding treatment methods.
Why Does the Filter Press Not Maintain Pressure?
Hydraulic system failure
The pressure-maintaining function of the filter press relies on the normal operation of the hydraulic system. If there is a fault in the hydraulic system, such as leakage, pump failure, or valve blockage, stable pressure cannot be maintained, resulting in no pressure maintenance.
The hydraulic pump is an important component that provides pressure to the hydraulic system. If the hydraulic pump fails, the seal is worn or internally clogged; it will not be able to provide sufficient pressure, resulting in failure to maintain pressure.
Hydraulic valves control the pressure and flow of the hydraulic system. If the valve is faulty, such as stuck, blocked, or improperly adjusted, the pressure will not be maintained stably.
Material blockage or material property changes
When the solid particles in the material are too many or too fine and block the pores of the filter plate or filter cloth, the hydraulic system cannot exert sufficient pressure, resulting in no pressure maintenance. Some materials may change during the filtration process, such as viscosity increase, temperature change, etc., which may cause the hydraulic system to be unable to maintain the original pressure.
Hydraulic oil quality issues
Problems such as hydraulic oil contamination, gas dissolution, or excessive oil temperature may affect the normal operation of the hydraulic system, resulting in failure to maintain pressure.
Wrong operation
The operator may perform improper operations or misoperations, such as setting the wrong pressure parameters, opening the wrong valve, operating too fast, etc. These errors may result in failure to maintain pressure.
How to Handle the Failure of Automatic Pressure-Maintaining Filter Press?
Check hydraulic system
First, you need to check whether there is a fault in the hydraulic system, check whether the hydraulic pump, hydraulic cylinder, valve, and other components are working properly, and repair or replace the faulty components.
Check the hydraulic system for leaks, carefully inspect hydraulic lines, connections, and seals to find leaks, and repair or replace damaged components. Make sure the hydraulic system seals are intact to prevent hydraulic oil leakage.
Make sure the hydraulic oil is free from contamination, gas dissolution, or overheating. Replace the hydraulic oil when necessary and perform necessary oil treatment.
Clean filter media
If the filter material is clogged and does not maintain pressure, the filter material needs to be cleaned. Appropriate cleaning methods can be adopted, such as flushing with clean water or reverse blowing to remove clogged solid particles.
Adjust operating parameters
According to the changes in the properties of the filtered materials, the operating parameters should be adjusted appropriately. For example, parameters such as pressure, temperature, and filtration speed can be adjusted to adapt to changes in materials to maintain stable pressure.
Regular maintenance
The hydraulic automatic pressure-maintaining filter press requires regular maintenance, such as cleaning the hydraulic system, replacing hydraulic oil, checking valves, etc. Regular maintenance.
