Description
Technical field
The utility model relates to the automobile air conditioner compressor field, is specifically related to be equipped with in the gas-entered passageway compressor air inlet bonnet of filter screen.
Background technique
Automobile air conditioner compressor is the core component of automotive air-conditioning system, the main effect of compressor in the refrigeration system the inside is that the low-temp low-pressure gas compression that sucks from gas-entered passageway is become high temperature and high pressure gas, for whole refrigeration cycle provides power, therefore, the automobile air conditioner compressor refrigerant cycle power producer of automobile refrigerating system especially.Air intake filter is not set in the gas-entered passageway of existing automobile air conditioner compressor bonnet, the compressor inhaled air reruns to relief opening through continuous pressure treatment, the fibril of in this process, following a part of compressor cold oil possibly or even being inhaled into together with air, impurity such as fine particle flow together and form the viscous mixture, enter the circulatory system of air-conditioning, not only can the deterioration cooling machine oil, more can cause insufficient lubrication, moving element wearing and tearing in the cylinder, adhesion, or even card cylinder, reduce the working efficiency and the working life of air conditioner, had a strong impact on machine run safety.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of compressor air inlet bonnet that has the inherent filtration device, and the air-filtering that this bonnet can will enter compressor avoids airborne granular foreign material to enter in the cylinder of compressor, cause air outlet hole to stop up, compressor is scrapped.
Have the compressor air inlet bonnet of inherent filtration device, comprise rear cover assembly, rear cover assembly is provided with gas-entered passageway, is provided with filter screen in the gas-entered passageway, and gas-entered passageway lower end and sidewall are provided with air outlet hole, and filter screen is between air outlet hole and inlet hole.
Tighten fixing with the annulus of hard around the described filter screen.
The inlet end of described gas-entered passageway is provided with step, and annulus is stuck in the step.
Described annulus and gas-entered passageway equal diameters, annulus is fixed with glue and gas-entered passageway wall.
Evenly be provided with at least two fixing rods around the described annulus, the other end of fixing rod is the hook of excurvation, and hook colludes the edge at the suction port of air inlet through hole.
Described annulus is fixed in the annulus cover, and the outer surface of annulus cover evenly is provided with raised points, and the internal surface of gas-entered passageway is provided with the projection circle that two circles are close to, and raised points can be clamped between the two circle projection circles.
Described annulus is arranged with the semicircular handle that expansion force is arranged.
Described handle is detachable or rotatable the connection with the annulus cover.
After this bonnet is installed with automobile air conditioner compressor, during use, ambient air is inhaled into the process of cylinder from gas-entered passageway, air passes through filter screen, airborne large particle is stayed on the filter screen, after avoiding large particle to enter cylinder, stop up the little air outlet hole of cylinder, cause automobile air conditioner compressor integral body to scrap, particulate matter on filter screen more for a long time, filter screen take out is changed, or take out clean out after, be installed in the gas-entered passageway again, if filter screen can not take out, available suction means sucks out particulate matter, can repeat repeatedly to use, and has prolonged the working life of compressor.
