How to keep filter press in high working efficiency?

To increase the service life of the plate and frame filter press, daily maintenance is essential, but what annoys many users is how is the correct method of maintaining the plate and frame filter press?

First, it is forbidden to start the factory when the filter plate is less than the specified quantity, so as not to damage the machine parts. Check the arrangement of the filter plate before feeding, the filter cloth must not be folded to prevent large leakage; after the cake is unloaded, the filter plate must be arranged closely and tightly arranged.

Second, after all is normal, the filter plate can be pressed and filtered. The filter pressure and filter temperature must be within the specified range. Excessive filter pressure will cause leakage. If the filter temperature is too high, the plastic filter plate is easily deformed and suspended when feeding. The liquid should be uniform in concentration. There must be no impurities; after unloading the cake, the filter cloth and filter plate must be rinsed clean, and the residue should not be allowed to stick in the sealing surface or the feed channel, otherwise it will affect the smoothness of the feed and the seal ability of the filter plate, resulting in two sides of the filter plate Unbalanced pressure causes deformation and damage to the filter plate.

Third, the normal plate and frame filter press can only be fed before commissioning, and the whole machine should be fully inspected before each shift. The mechanical compression transmission components and the reduction gearbox must be filled with lubricating oil; the hydraulic compression should check the oil storage capacity of the oil tank and the working pressure of the hydraulic station. The hydraulic oil is generally replaced once a year. When replacing, the hydraulic system should be cleaned once, the hydraulic station working pressure is less than the maximum working pressure of the oil cylinder, but the minimum cannot be lower than the allowable value of the filtering pressure. If it is too small, it will cause large leakage and damage the machine parts.

Fourth, the selection of the filter cloth must meet the filtering technical requirements of the filter paddle. The new filter cloth of the plate and frame filter press should be shrunk before the production. 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 feed hole cloth should be close to the wall of the cylinder, otherwise it will cause unclear filtration, low filtration rate, and the cloth cylinder is broken, which will not achieve the expected results of the filtration purpose.
