High-pressure diaphragm Filter Press, also known as high-pressure filter cake machine, is a common solid-liquid separation equipment and is widely used in chemical industry, environmental protection, metallurgy and other fields. It drives the formation and separation of the filter cake through pressure, and has the advantages of good filtration effect and simple operation. However, in order to ensure the normal operation of the high-pressure diaphragm filter press and extend its service life, daily maintenance is very important.

1. Cleaning and maintenance 1. After the power is safely cut off, use a wet cloth or a dust blower to clean the inner and outer surfaces of the high-pressure diaphragm filter press, especially the filter plate, filter frame and other parts to ensure that there is no dust and impurities. 2. Regularly clean the solid residue on the filter cloth and filter plate. Use a clean brush or dust blower to gently brush it, be careful not to damage the filter cloth.

2. Replacement of filter cloth 1. After long-term use, the filter cloth will be worn, damaged, etc., and needs to be replaced in time. 2. Before replacing the filter cloth, make sure that the high-voltage diaphragm filter press is in a safe shutdown state and disconnect the power supply. 3. Remove the top and bottom blue of the filter press, remove the old filter cloth, and clean the surface of the filter plate and filter frame. Then install the new filter cloth onto the filter plate and filter frame and make sure it is secure. 4. After changing the filter cloth, test run according to the normal operating procedures and confirm that there are no abnormalities before using it.

3. Inspection and replacement of seals 1. The seals of high-pressure diaphragm filter presses are generally made of rubber, and are prone to aging, hardening and other conditions after long-term use. They need to be inspected and replaced in time. 2. When checking the seal, first turn off the power and ensure that the high-voltage diaphragm filter press is shut down. Then check whether the seal has cracks, deformation, etc. If problems are found, they need to be replaced immediately. 3. When replacing the seal, pay attention to selecting seals of the right size and material, and install them correctly to ensure that the sealing effect is good.

4. Lubrication and maintenance 1. The sliding parts of the high-pressure diaphragm filter press must be regularly filled with lubricating oil to ensure the normal operation of the equipment. 2. Before adding lubricating oil, clean the dust and impurities around the lubricating point to ensure no pollution. 3. When filling lubricant, fill in the manner and amount specified in the equipment instruction manual and be careful not to overdo it.

5. Inspection and maintenance of hydraulic systems 1. Since the high-pressure diaphragm filter press is operated by hydraulic drive, the normal operation of the hydraulic system is crucial to the stability and reliability of the equipment. 2. Regularly check the filter element, oil filter and other components in the hydraulic system, and clean or ｒｅｐｌａｃｅ damaged parts. 3. Pay attention to check the quality of the hydraulic oil. If the oil is found to be deteriorated or contaminated, ｒｅｐｌａｃｅ the hydraulic oil in time. 4. When the machine is shut down, drain the residual oil in the hydraulic system in time to keep the system clean.

The daily maintenance of high-pressure diaphragm filter press includes cleaning and maintenance, filter cloth replacement, seal inspection and replacement, lubrication maintenance, and hydraulic system inspection and maintenance. Through correct maintenance measures and methods, the normal operation of the high-pressure diaphragm filter press can be ensured and service life can be extended, production efficiency can be improved, maintenance costs can be reduced, and the economic benefits and sustainable development of the enterprise can be contributed to the economic benefits and sustainable development of the enterprise.
