Common troubleshooting of hydraulic oil filter

Specific analysis of the shortcomings of the hydraulic oil vacuum filter:

(1) Damage to filter plate: 

1. Manufacturing quality of the filter plate; 

2. In the diaphragm pressing method, the diaphragm filter oil machines and the processing quality of the internal steel lining should be considered at the same time. 

3. Whether the selection of filter plate material matches the head of the feed pump.

Under normal conditions, the pressure at both ends of the filter plate of the hydraulic filter is in a balanced state. When the two ends of the filter plate are in different filtration stages, that is, one side is filtering and the other side is hydraulic squeezing, a pressure difference is formed at both ends of the filter plate, thereby damaging the filter plate. 

The reasons are: 

1. After the initial filtration of the filter press, the feed pump stops for a long time halfway, and the filter cake in the semi-mobile state in the filter chamber sinks to varying degrees; 

2. During the unloading process, the amount of mud remaining at both ends of the filter plate is greatly different.

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

(2) Spraying between filter plates: 

During the filtering operation of the automatic vacuum oil filter, spraying occurs between the filter plates. 

The reasons are: 

1. The thrust plate is not pressed, or the pressing force of the hydraulic cylinder is too small. 

2. The filter cloth is damaged; 

3. The filter cloth is folded on the pressing surface of the filter plate frame; 

4. The two end beams have different degrees of lateral bending (horizontal direction).

The hydraulic oil vacuum oil filter can quickly remove water, gas, impurities and harmful components in the lubricating oil,l such as acetylene, hydrogen, methane, ammonia, etc., and restore the function of lubricating oil. The hydraulic oil vacuum oil filter can effectively ensure the normal operation of the oil system equipment and avoid accidents. 

The hydraulic oil vacuum oil filter is equipped with three-stage filtration, which is simple and sensitive, easy to operate, does not require filter paper, does not pollute the site, and can not only effectively filter out harmful impurities in the oil, but also is particularly suitable for long-distance, high-lift refueling and oil pumping in the power sector. This equipment does not have a decolorization function and can only purify impurities in the oil. 

The hydraulic oil vacuum filter adopts a deep, high-precision DFH double rectangular filtration system that combines the latest multi-layer stainless steel mesh filtration and composite polymer adsorption, which has strong dirt holding capacity and high filtration accuracy.
