Description
Technical field
The present invention relates to the automobile air conditioner compressor field, be 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 Function 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 circulation 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 air that compressor sucks reruns to relief opening through continuous pressure treatment, the fibril of in this process, following possibly a part of compressor cold oil or even being inhaled into together with air, the impurity such as fine particle flow together and form the viscous mixture, enter the circulatory system of air-conditioning, not only can deteriorated cooling machine oil, more can cause insufficient lubrication, moving element wearing and tearing in the cylinder, adhesion, or even card cylinder, reduce working efficiency and the working life of air conditioner, had a strong impact on the machine security of operation.
Summary of the invention
In order to solve the problem of above-mentioned existence, the present invention discloses a kind of compressor air inlet bonnet with 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.
Compressor air inlet bonnet with the inherent filtration device comprises rear cover assembly, and 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 and annulus cover are detachable or are rotatably connected.
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, when the particulate matter on the filter screen is more, filter screen take out is changed, or take out clean out after, be installed in again in the gas-entered passageway, if filter screen can not take out, available suction means sucks out particulate matter, can repeatedly use, and has prolonged the working life of compressor.
