Description
Technical Field
The utility model belongs to the technical field of engineering machinery, relates to an air filter, and particularly relates to a system for monitoring the blocking degree of the air filter of an engine of the engineering machinery.
Background
The air filter is an important component on the engine of the engineering machinery and is used for filtering air entering the engine and blocking dust in the air. The working environment of a working machine is often very dusty, so that the filtering capacity of the air filter determines the working life of the engine to a certain extent.
Factors that determine the filtering capacity of the air cleaner include the quality of the filtering material, the degree of maintenance of the air cleaner, and the time to replace the air cleaner.
In the aspect of quality of the filter material, the good filter adopts the filter material with strong filtering capacity, the capacity of preventing dust from entering the engine is strong, but the cost is higher, and is generally multiple times or more than ten times of the inferior air filter, so that the situation of being good in next generation often occurs, and the service life of the engine is shortened.
In the aspect of the maintenance degree of the air filter, because the working environment of the engineering machinery is large in dust, the dust on the air filter is blown off by compressed air in a reverse direction every day or every two days, so that the dust filtering capacity of the air filter is improved, and therefore whether equipment users blow off the dust on the air filter regularly and the cleaning degree of the air filter determine the filtering capacity of the air filter.
In the aspect of the time of changing air cleaner, if air cleaner's filter material had been damaged, can lead to dirty air directly to pass through the filter, or air cleaner has blockked up, also can lose filter capacity, consequently, these two kinds of situations appear, all in time need change new air cleaner, consequently change air cleaner's moment very important, change early, improve equipment use cost, change late, dirty air gets into the engine, influences the life-span of engine. In actual work, regardless of the working environment of the engineering machinery, the air filter is forcibly replaced by adopting a 'fixed interval date', and the 'fixed interval date' maintenance method has the defect that the replacement interval time of the air filter is too long for equipment constructed in an environment with heavy dust (such as an opencast coal mine), so that the service life of an engine is influenced; conversely, for equipment constructed in clean air environments (e.g., urban environments), the air filter change interval may be too short, increasing equipment use costs.
In conclusion, how to detect the capacity of the air filter and remind personnel to clean and replace the air filter is an urgent problem to be solved in actual work.
