Abstract
The utility model provides a miniature air compressor which is installed on LR100 serial engines produced by the China First Tractor Manufacturing Plant and is used as an air supply source in the air braking of an automobile or a tractor. The utility model is characterized in that an air inlet valve and an air discharge valves adopt a reed valve structure, an unloading valve is arranged in an air inlet cavity (11), and the unloading valve is composed of an unloading valve plunger (10), a spring (8) and a spring seat (7) which are arranged in a stepped hole (9) which is arranged on a cylinder head (5). Compared with an original air compressor, the utility model has the advantages of high work efficiency, strong reliability, and long service life.
Description
The utility model provides a kind of micro-air compressor, is installed on the LR100 Engine Series that Chinese first tractor plant produces to be used for the Pneumatic braking device air supply source.
The existing air compressor that is installed on the LR100 Engine Series, the structure of inlet and outlet valve generally is to adopt tabular valve block---spring structure, because the air compressor rotating speed height that the LR100 Engine Series requires, the vibration natural frequency of former air valve structure can not adapt to, and valve block can not exist the volumetric efficiency of air compressor very low (below 40%) with the moving up and down and in time open and close of piston, inefficiency, the delivery temperature height, the life-span is short, and shortcomings such as poor reliability, deficiency in economic performance.
The utility model is exactly the improvement invention of carrying out in order to overcome above-mentioned shortcoming.
Solution of the present utility model is that advancing on the air compressor of LR100 Engine Series, heat-extraction system adopt the Reed Valve structure, and the volumetric efficiency of its air compressor is improved, and operating temperature reduces, and energy consumption descends.And be provided with the air inlet relief arrangement in the gas handling system of air compressor, and reduce power consumption and wearing and tearing, prolonged the life-span of air compressor.
Major character of the present utility model is to be close to valve plate (4) to locate to be provided with exhaust reed valve plate (6) on valve plate (4), is close to valve plate (4) and locates to be provided with air inlet reed valve plate (12) below valve plate (4).Air-inlet cavity (11) in cylinder cap (5), in be provided with cylinder lotus valve, it is made up of the unloading valve plunger (10), bullet (8), the bullet seat (7) that are contained in cylinder cap (5) shoulder hole (9), unloading valve plunger (10) is pressed in above the valve plate (4), and valve plate (4) locates to be provided with unloading hole (13) over against cylinder lotus valve plunger (10).Air compressor is contained on the LR100 Engine Series by the connection dish (1) of crankcase (15) one ends.
Below in conjunction with drawings and Examples the utility model is described in detail.
Description of drawings:
Fig. 1 is a plan view of the present utility model
Fig. 2 is a left view of the present utility model
Be a specific embodiment of the present utility model below.
As depicted in figs. 1 and 2, the utility model is contained on the LR100 Engine Series by the connection dish (1) of crankcase (15) one ends, motor drives bent axle (16) by gear (not drawing among the figure) and rotates, when bent axle (16) drivening rod (2), piston (3) when moving downward by top dead center, cylinder (14) internal pressure is lower than barometric pressure, under the barometric pressure effect, air inlet reed valve plate (12) is opened, the air compressor air inlet.Piston (3) runs to lower dead center, and intake process finishes.Along with bent axle (16) rotates, piston (3) is up, cylinder (14) internal pressure increases, air inlet reed valve plate (12) is closed, when pressure during greater than exhaust reed valve plate (6) pressure outside, exhaust tongue (6) is opened, and air compressor begins exhaust, pressurized air enters gas cylinder (drawing among the figure) by pipeline, when piston (3) exhaust process end when running to top dead center.Along with bent axle (16) is rotated further, repeat said process, realize the utility model work.
In order to reduce idle work consumption of the present utility model, in the air-inlet cavity (11) of cylinder cap (5), be provided with the unloading valve device.Cylinder cap (5) is gone up in the air-inlet cavity (11) and also is provided with shoulder hole (9), and its position is equipped with unloading valve plunger (10), spring (8), spring seat (7) etc. successively and is formed unloading valve over against the last unloading hole (13) of valve plate (4) in shoulder hole (9).Force unloading valve plunger (10) to compress valve plate (4) by spring (8) and seal unloading hole (13).When reaching set pressure 0.67～0.73MPa in the gas cylinder, pressurized air enters unloading valve by gas-tpe fitting (17), and unloading valve plunger (10) is lifted, and opens the unloading hole (13) on the valve plate (4), the interior gas of cylinder (14) is communicated with the air compressor off-load with atmosphere.Along with compressed-air actuated consumption, the gas cylinder internal pressure descends, and when reducing to 0.55-0.59MPa, unloading valve plunger (10) return under the effect of spring (8) compresses unloading hole (13) again, and air compressor recovers pump gas.When pump gas made gas cylinder pressure rise to set pressure, unloading valve repeated above-mentioned working procedure.
