1. the mechanical pressure transmission parts and reduction gear box of the van type filter press must be filled with lubricating oil; Hydraulic pressure is used to check the fuel storage capacity of the fuel tank and the working pressure of the hydraulic station. The hydraulic oil is usually changed once a year. During replacement, the hydraulic system shall be fully cleaned, and the working pressure of the hydraulic station shall be less than the working pressure of the cylinder, but the small value shall not be less than the allowable value of the filter pressure. If it is too small, it will cause a large amount of leakage and the components will be damaged.
2. when the number of filter plates of the van type filter press is less than the specified number, it is forbidden to start operation to avoid damaging the machine. Check the arrangement of filter plate before feeding. The filter cloth shall not be folded to prevent large leakage. After the filter cake is unloaded, the filter plates must be tightly packed and aligned.
3. press and filter the filter plate after everything is normal. The filtration pressure and temperature must be within the specified range. If the filtration pressure is too high, it will cause leakage. The filtration temperature is too high. Plastic filter plate is easy to deform. The concentration shall be uniform. No mixed materials; After the filter cake is unloaded, the filter cloth and filter plate must be washed clean, and the residue is not allowed to stick to the sealing surface or the feeding channel, otherwise the smoothness of the feeding and the sealing performance of the filter plate will be affected, and the unbalanced pressure on both sides of the filter plate will damage the filter plate.
