After the chamber filter press has been used for a long time, its operational efficiency and work quality will be affected, so it should be regularly maintained. Regarding how to maintain the chamber filter press, we have sorted out the following points.

1. The feeding operation can only be done after debugging the normal chamber filter press, and the whole machine should be checked before each shift. It is necessary to add enough lubricating oil to mechanically press the transmission parts and the reduction box; for the hydraulic press, check the oil storage capacity of the oil tank and the operating pressure of the hydraulic station. The hydraulic oil is usually replaced once a year. When replacing, the hydraulic system should be cleaned once and the hydraulic station is operated. The pressure is lower than the maximum working pressure of the oil cylinder, but the minimum pressure cannot be lower than the allowable value of the filter pressure. If it is too small, it will cause large leakage, and if it is too large, it will damage the parts.

2. It is forbidden to start the operation when the number of filter plates is less than the specified number, so as to avoid damage to the parts. Check the placement of the filter plate before feeding, and the filter cloth should not be folded to avoid large leakage.

3. The slurry, washing liquid, or compressed air valve must be activated according to the operating procedure, and cannot be activated together. The compressed air pressure cannot exceed the filtering pressure during the squeeze.

4. The selection of the filter cloth for the chamber filter press must meet the filtration technical requirements of the filter paddle. The new filter cloth should be shrunk before manufacturing, and the opening diameter should be smaller than the filter plate aperture. When matching the filter plate, the cloth hole and the plate hole should be relatively concentric. The feeding hole cloth should be close to the cylinder wall, otherwise, there will be problems such as unclear filtration, low filtration rate, and rupture of the cloth cylinder, and the expected effect of filtration will not be achieved.

5. When moving the filter plate, the force should be even and appropriate, and no bumping or beating is allowed to avoid damage to the sealing surface and the filter wrench handle. After a period of use, the filter cloth will become hard and its function will be reduced. For this reason, regular inspections are required. If it is found that there is a phenomenon that affects the filtration rate, it can be neutralized and cleaned with a correspondingly low concentration of weak acid and weak alkali to restore the function of the filter cloth. If it cannot be recovered, it will be replaced in time.

6. After everything is normal, you can press the filter plate for pressure filtration. The filtration pressure and filtration temperature must be within the specified range. If the filtration pressure is too high, it will cause leakage. If the filtration temperature is too high, the plastic filter plate is easy to deforms. The concentration is uniform and there should be no impurities.

7. In the early stage of pressure filtration, the filter is turbid. When a layer of the filter cake is formed on the filter cloth, the filtrate will become clear. If the filtrate has been turbid or changed from clear to mixed, it may be that the filter cloth is damaged or the cloth hole and the plate hole are wrong. At this moment, the valve should be closed or the feeding should be stopped to replace the filter cloth.

The above is about the maintenance method of the transmission part of the chamber filter press, I hope it will be helpful to everyone.
