Filter Press Maintenance Matters

- Nov 16, 2018 -

1. Debug the normal filter press before feeding, and check the whole machine before each shift. The mechanical compression transmission parts and the reduction gear box must be filled with lubricating oil; the hydraulic pressure is used to check the oil storage capacity of the fuel tank and the working pressure of the hydraulic station. The hydraulic oil is generally replaced once a year. When the replacement is made, the hydraulic system should be fully cleaned and the working pressure of the hydraulic station Less than the maximum working pressure of the cylinder, but the minimum can not be lower than the allowable value of the filtration pressure. If it is too small, it will cause a large leakage, and the assembly will be damaged.

2. It is forbidden to start the work in the case where the filter plate is less than the specified quantity, so as to avoid damage to the machine. Check the arrangement of the filter plates before feeding. The filter cloth should not be folded to prevent large leakage. After the cake is unloaded, the filter plates must be tightly packed and aligned.

3. After all normal, the filter plate can be pressed and filtered. 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 will be easily deformed. The concentration should be uniform. There must be no mixed materials; after the cake is unloaded, the filter cloth and the filter plate must be rinsed clean, and the residue is not allowed to be stuck in the sealing surface or the feeding channel, otherwise the smoothness of the feed and the sealing of the filter plate will be affected, so that the sides of the filter plate Unbalanced pressure causes damage to the filter plate.
