    There are many ways to operate a filter press, and you can not just ask for trouble and ignore the right steps:
    1, the filter is prohibited in the filter plate less than the required number of cases of plant work, so as not to damage the parts. Check the filter plate before feeding the situation, filter cloth can not have a folding phenomenon, to prevent the occurrence of greater leakage; unloading cake after the filter plate must be tightly arranged neatly arranged.
    2, the normal operation of the filter press before the work, each class before the work to make a comprehensive inspection of the machine.
    3, filter press compression parts and gear box must be added enough oil;
    4, the filter press is too high will cause leakage, filtration temperature is too high plastic filter plate is easy to deformation, the concentration of the suspension to be uniform
    5, the choice of filter cloth must meet the filtration technology requirements of the filter, the new filter cloth should be shrunk before the production, opening diameter should be less than the filter plate diameter, matching filter plate hole and plate hole should be relatively concentric, Cloth should be attached to the wall, otherwise it will cause, filter unclear, low filtration rate, cloth tube rupture, fail to achieve the desired purpose of filtering.
    6, the filter press in the early filter, the filter is more turbid, when the filter cloth to form a layer of filter cake after the filtrate will become clear. If the filtrate has been turbid or clear mixed, it may be broken cloth or cloth hole and plate hole deviation, this time to close the valve or stop the feed to replace the filter cloth. The filter plate allows a small amount of leakage caused by the capillary phenomenon of the filter cloth.
    The operation of the filter press shall not have mixed objects, otherwise it will affect the flow of the feed and the sealing of the filter plate, and thus the pressure on both sides of the filter plate is unbalanced, resulting in deformation of the filter plate.
