Analysis of common faults of oil filter
Common problems in oil filter machines are damage to the filter plate and spray between the filter plates. The following is a separate analysis for different problems:
(1) Filter plate damage
Damage to the filter plate of the chamber filter press is a common problem. If the number of filter plates is large, the following elements should be analyzed:
1 production quality of the filter plate;
2 In the splitting and pressing method, the amount of the Chongqing oil filter and the processing quality of the internal steel lining should be considered together.
3 Whether the selection of the filter material and the lift of the feed pump match;
Under normal conditions, the pressure on both sides of the filter plate is in equilibrium. When the two sides of the filter plate are in different filtration stages, that is, one side is filtered and the other side is hydraulically kneaded, a pressure difference is formed on both sides of the filter plate, and then the filter plate is damaged. The reason:
After the filter press starts to filter, the feed pump is parked halfway for a long time, and the filter cake in the semi-active state of the filter chamber exhibits different degrees of sinking;
2 During the unloading process, the amount of mud remaining on both sides of the filter plate is greatly different;
3 The filter hole of the filter plate is blocked.
(2) Spraying between filter plates
Active vacuum Chongqing oil filter in the filtration operation, the phenomenon of spraying between the filter plates, the reasons:
The thrust plate is not pressed or the pressing force of the hydraulic cylinder is too small.
The filter cloth is damaged;
On the pressing surface of the filter board frame, the filter cloth is folded;
The two sides of the beam show different degrees of lateral tortuosity (horizontal direction); Chongqing oil filter manufacturers
The solution is to carefully arrange the residual filter cake (especially the lower part) on the pressing surface of the filter plate during unloading, and perhaps flush the filter plate in time to ensure the cleaning surface of the filter plate is clean; tie the filter cloth to ensure it is flat Sex.
