Description

A filter for cylinder air intake

technical field

The utility model belongs to the technical field of fluid filtration, in particular to a filter for cylinder air intake.

Background technique

A cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The air in the engine cylinder converts heat energy into mechanical energy through expansion, and the gas is compressed by the piston in the compressor cylinder to increase the pressure. The casing of the turbine, rotary piston engine, etc. is usually also called the cylinder, and the corresponding valve is driven by the cylinder. The flue exhausts smoke, and the working environment is harsh. Therefore, when the air in the working circuit of the cylinder is taken in, it needs to filter out the corresponding impurities in the air through a filter, but it still has the following disadvantages in actual use:

When the cylinder intake filter is working, the air is directly filtered through the filter element. After the air is filtered, a lot of dust will be filtered out. When the machine is turned off, the dust will accumulate on the filter surface of the filter element. , resulting in a decrease in the filtration efficiency of the filter element;

When the filter for air intake of the cylinder is working, after the filter element has been used for a period of time, the overall filtering performance of the filter element will drop significantly. Continued use will cause the pressure in the working air circuit of the cylinder to drop, which will affect the working sensitivity of the cylinder, and the filter element needs to be replaced. The cycle of replacing the filter element is short, and the cost of replacing the filter element is relatively high.
