What are the common problems of coalescing dehydrated oil filter?

Coalescing dehydrating oil filter is to solve the problem of excessive water content in various oils. The dehydration technology of "coalescing separation" is used to filter the particle impurities and emulsified water in the oil, and free water does not damage the quality of the product. For the oil containing a lot of water, the separation effect is more obvious.

(1) The filter plate is damaged.

Because under normal conditions, the pressure on both sides of the filter plate is in a balanced state. If the two sides of the filter plate, one side is filtration, the other side is hydraulic extrusion, then the two sides of the filter plate will form a pressure difference, thus damaging the filter plate.

1, the manufacturing quality of the filter plate, which requires us to pay attention to the quality of the oil filter when we buy the oil filter;

2, filter plate type selection and feed pump head matching;

3. In the diaphragm press, whether the quantity of diaphragm plate oil filter and the processing quality of internal steel lining are considered at the same time.

4. In the process of unloading, the amount of residual mud on both sides of the filter plate differs greatly;

5. After starting filtration, the feeding pump stops for a long time, and the filter cake in the semi-flowing state in the filter chamber will sink to different degrees;

6. The feed hole of the filter plate is blocked.

(2) There is spraying phenomenon between filter plates

1. The press surface of the filter plate frame may fold the press cloth;

2. Press cloth is damaged;

3, both sides of the beam appear different degrees of lateral bending;

4, the thrust plate is not pressed or the pressing force of the hydraulic cylinder is small.

The above is to introduce the common problems of coalescing dewatering oil filter. In the daily use process, it should be checked regularly. If problems are found, maintenance should be conducted in time, so as to extend its service life.
