First, the normal filter filter plate can be debugged for feed operation and all machines should be viewed before each shift.Mechanical compression drive and deceleration gearbox require sufficient lubricant; hydraulic pressure is used to check the oil storage capacity of the tank and the operating pressure of the hydraulic station.Hydraulic oil is usually replaced every year, the hydraulic system shall always be clean and the hydraulic station operates.Pressure is less than the cylinder operating pressure, but not less than the filter pressure.If too small, it can cause numerous leaks and damage to the machine.
Second, when the filter plate is less than normal, starting operation is prohibited to avoid damage to the machine.Check the condition of the filter plate before feeding.Do not fold the filter cloth to avoid heavy leakage.
Third, the slurry, cleaning fluid or compressed air valve needs to be started according to the operation procedure, but not at the same time.The compressed air pressure during extrusion shall not exceed the filtration pressure.
Fourth, the selection of the filter cloth needs to meet the technical requirements of the filter filter.In this regard, the press is doing very well.Reduce it before making a new filter cloth.The diameter of the opening shall be less than that of the filter plate.When the filter plates cooperate, the holes should be between the cloth and the holes relatively concentric.The fabric of the inlet hole shall be close to the filter wall.Otherwise, the filter will be unclear and filtered.Low speed, fabric damage, etc., did not achieve the desired filtering effect.
fifth.When moving the filter plate of the filter, the force shall be uniform and appropriate, and shall not be impacted or impacted to avoid damage to the sealing surface and filter wrench.The filter cloth harden after a period of use and its function decreases.If changes in filtration rate are found, neutralization can be washed with corresponding low concentrations of weak acid and weak bases.If you cannot recover, you can change the recovery function in time.
Sixth, after being completely normal, the filter plate can be pressed and filtered.Filfiltration pressure and temperature need to be within the normal range.If the filtration pressure is too high, it causes leakage.If the filter temperature is too high, the plastic filter plate is easily deformed.The concentration is uniform with no impurities.
The press filter plate is turbid in the early stages of the press.When the filter cake forms a layer of filter cake, the filtrate becomes clarified.If the filter fluid is turbid or mixed through washing, the holes may be damaged and the holes in the plate.At this point, close the valve or stop the refueling filter.
