As a common filtration equipment, plate and frame filter press is widely used in various industries, such as chemical industry, environmental protection, food, etc. However, during use, if the pressure is too high, there may be some safety hazards. This article will analyze the causes of excessive pressure in the plate and frame filter press, the possible consequences, and preventive measures to ensure the safe operation of the equipment.
1. The reason for the excessive pressure of the plate and frame filter press.
1.Hydraulic system failure: The hydraulic system is the core part of the plate and frame filter press, if the hydraulic system fails, such as oil pump damage, overflow valve failure, etc., it will lead to abnormal increase in system pressure.
2.Filter plates are not tightly arranged: The filter plates are the main component of the plate and frame filter press, and if the filter plates are not arranged tightly, it will cause the filter press to be subjected to additional pressure during the closing process, which will make the system pressure too large.
3.Clogged pipes: Clogged filter press pipes can lead to obstruction of material delivery, resulting in an abnormally high system pressure.
4.Abnormal operation: During use, if the operator operates improperly or violates the rules, such as overpressure operation, etc., it will also lead to excessive pressure of the plate and frame filter press.
Second, the possible consequences caused by excessive pressure of the plate and frame filter press.
1.Equipment damage: Long-term high-pressure operation will cause excessive load on the various components of the plate and frame filter press, resulting in equipment damage and shortening the service life.
2.Leak Accidents: Excessive pressure can cause seals to fail, causing leakage accidents and posing a threat to the safety of operators.
3.Environmental pollution: Leakage may cause pollution to the surrounding environment and damage the ecological environment.
4.Production Interruption: Equipment damage or leakage accidents can lead to production interruptions and financial losses for businesses.
3. Measures to prevent excessive pressure of plate and frame filter press.
1.Regularly inspect the hydraulic system: Regularly inspect the hydraulic system to ensure that key components such as oil pumps and relief valves are working properly.
2.Filter plate maintenance: Regularly check the arrangement of the filter plate, adjust or replace the damaged filter plate in time to maintain its tightness.
3.Pipe cleaning: Clean the filter press pipes regularly to prevent clogging.
4.Operator training: Strengthen the training of operators to ensure that they can use the plate and frame filter press correctly and safely.
5.Install safety protection devices: Install safety protection devices on the filter press, such as overpressure protection devices, etc., to automatically cut off the power supply or alarm when the pressure is too high.
6.Formulate safety operation procedures: formulate and implement safety operation procedures, standardize the operation behavior of operators, and avoid overpressure operation.
7.Regularly test the status of the equipment: regularly conduct a comprehensive inspection of the plate and frame filter press, and find and deal with the hidden dangers in time.
8.Establish equipment maintenance files: Establish equipment maintenance files, record the repair and maintenance of equipment, and facilitate the overall management of equipment.
IV. Conclusions. The potential safety hazards of excessive pressure of plate and frame filter press cannot be ignored. In order to ensure the safe operation of the equipment and the normal production of the enterprise, a series of preventive measures should be taken, such as regularly checking the hydraulic system, training operators, installing safety protection devices, etc. At the same time, equipment management should be strengthened, the safety awareness of operators should be improved, and the occurrence of safety accidents should be fundamentally avoided.
