To make the hydraulic filter work better, its maintenance is also necessary. So, do you know how to maintain the hydraulic filter? What are the misunderstandings of maintenance that you don't know?
Maintenance misunderstanding of hydraulic filter
- Open and clean it every day
In the general environment, the hydraulic filter may not need to be cleaned every day. If it is disassembled too frequently, it is easy to mix dust and wear the cylinder and other accessories. The internal structure of the paper dry filter is composed of multi-layer fibers, and the spatial three-dimensional structure realizes greater pollution acceptance and higher filtration accuracy through three-dimensional orientation. Through the professional test of the engine manufacturer, the filtering effect of the new filter is sometimes not as good as that of the old filter. Generally, the filtering effect of a 60% stolen filter is the best. Because part of the dust occupies the air inlet channel of the filter, it can prevent the dust with smaller particles from entering the filter. So don't rush to clean the filter every day. It's best to wait until the filter alarms.
- Pay attention when cleaning the hydraulic filter
Don't beat the filter hard. Expect the cleaner the better. Since the filter is a little stolen, the filtering effect is better. Why toss back and forth? It can't hurt the filter paper? When blowing, it blows from inside to outside. In turn, it helps. The dust that was originally prevented is blown in. Do not clean the filter with other solvents.
- The circuit or indication of the air filter alarm must work normally
Some customers may think it doesn't matter whether these two thin wires are connected or not. Just observe the air filter by yourself. It's easier to connect it and it's better for the machine. In case of blockage or abnormal alarm, there will be insufficient power and black smoke.
What are the requirements for the use of hydraulic filters in hydraulic accessories?
- Reasonably determine the efficiency of filters at all levels. The key points for determining the efficiency of filters are: the performance requirements of final filters, the efficiency specifications of pre-filters should be reasonable, and the maintenance of primary filters and precision filters should be convenient.
- Increase the filter area. The filter has a large filter area, can contain more dust, and has a long service life. Moreover, the filtering area is large, the speed of airflow through the material is low, and the resistance of the filter is small.
- Adjust the efficiency of filters at all levels. The filtration efficiency of the pre-filter is low. You can block the dust in the pre-filter by adjusting the filtration efficiency of the pre-filter.
- The additional effect of the filter should not be emphasized.
- Climatic factors affect the filtering effect. If the filter is used in a large number of willows, corresponding measures should be taken in the air conditioning design, such as changing the height of the air inlet or adding a protective net at the air inlet. If the measures are improper, there is only one move left: change the filter frequently in the floating season.
- It's difficult to clean the filter thoroughly unless the technology is not promoted. Even if the filter is not cleaned thoroughly, it's best not to wash it thoroughly.
