The common faults of the oil filter include the damage of the filter plate and the spraying between the filter plates, Angle steel punching machine The damage of the filter plate of the box type filter press is a common fault. If the number of damaged filter plates is large, the following factors should be analyzed: manufacturing quality of filter plates; Angle steel Punching machine 。 Whether the selection of filter plate material matches the lift of feed pump.

In the diaphragm pressing mode of angle steel punching machine, the quantity of diaphragm oil filter and the processing quality of internal steel lining should be considered at the same time. Under normal conditions, the pressure on both sides of the filter plate is in balance. When the two sides of the filter plate are in different filtering stages, that is, one side is filtering and the other side is hydraulic extrusion, the pressure difference between the two sides of the filter plate is formed, thus damaging the filter plate.

The reasons for the angle steel punching machine are as follows: during the unloading process, there is a large difference in the amount of mud left on both sides of the filter plate; After the filter press starts filtering, the feed pump of the angle punching machine stops for a long time halfway, and the filter cake in the semi flowing state in the filter chamber sinks to varying degrees; The feed hole of the filter plate of the angle steel punching machine is blocked.
