Filter equipment failures

Mar 19, 2020

There are many problems encountered in the use of filter equipment, so how to resolve these problems?  The following editors introduce to us the common faults of filter equipment. The so-called short circuit of air filter equipment means that due to improper installation, the air filter is not tightly sealed, and air containing many impurities does not pass through the filter  The filter surface goes directly from the bypass into the cylinder.

 In this case, the air filter can no longer purify the intake air of the engine. The way to determine whether the air filter is short-circuited is to investigate the filter element once in a while. If the appearance of the paper filter element is always clean, the air  The filter does not work and there is a short circuit.

The key to avoiding short circuit of the air filter is to ensure that the device is sealed, that is, to prevent unfiltered air from entering the cylinder from the bypass.  When installing the air filter, it is necessary to pay attention to the following points: It is necessary to separate the two end faces of the paper filter element from the gasket and a good gasket. If the paper filter element is debonded between the two ends of the iron sheet, it should be replaced.

 The airfoil nut holding the air cleaner case should not be tightened too tightly to avoid deformation of the case.  Because the cover is stamped from a thin iron sheet, once the cover is deformed, the paper filter element will be broken; the connection between the air cleaner assembly and the engine intake pipe must be strong and tight to avoid air leakage.
