Embodiment 1

[0037] Such as Figure 1 to Figure 2As shown, a mobile single-screw compressor, the specific mechanism includes: 1. Star wheel; 2. Screw; 3. Compressor air inlet; 4. Compressor shell; 5. Oil separation device; Valve installation hole; 7. Compressor exhaust hole; 8. One-way valve; 9. Oil pool; 10. Oil suction pipe; 11. Compressor oil outlet hole; 12. Compressor oil inlet hole.

[0038] It consists of a screw 2 and two star wheels 1. The two star wheels 1 in the figure are arranged symmetrically, and the other star wheel is on the other side of the screw rod. The one-way valve is built in the compressor shell and connected to the air outlet after the meshing and compression of the screw 2 and the star wheel 1 to prevent the backflow of the gas in the high-pressure chamber, and to protect the compressor and drive the compressor motor. An oil separation device 5 is arranged inside the compressor housing 4, which can separate the gas-liquid two-phase matter from the one-way valve...

Abstract

The invention provides a movable type single screw compressor and belongs to the technical field of compressors. The movable type single screw compressor is composed of a screw and two star wheels inan engaged mode. A one-way valve is placed in a compressor shell and connected with an air outlet located after engagement compression of the screw and the star wheels, air in a high-pressure cavity is prevented from flowing back, and the effect of protecting the compressor and a compressor driving motor is achieved. An oil separation device is arranged in the compressor shell and can achieve an oil-gas coarse separation function by conducting collision separation on gas-liquid two-phase materials coming out of the one-way valve. Oil in an oil pool in the compressor is filtered via an oil suction pipe through an externally connected oil filter base (with a temperature control valve) and then injected into a compressor oil inlet hole, and the effects of lubricating and sealing the compressor are achieved.

Description

technical field [0001] The invention relates to the field of air compression and the field of locomotive power gas, in particular to a mobile single-screw compressor, which belongs to the technical field of compressors. Background technique [0002] At present, mobile gas consumption systems based on compressors are widely used, such as locomotive air brake systems, electro-pneumatic equipment and other mobile pneumatic equipment gas systems. The mobile gas system requires reliable stability under high-speed motion, and its reliability directly affects the safe operation of the entire equipment. [0003] At present, most of the existing mobile power gas systems are based on piston and twin-screw air compressor systems, but these two systems have problems such as complex structure, high cost, unbalanced force and low reliability. Single-screw compressor has the characteristics of simple structure, small size, light weight, high reliability, low noise, low operating cost and ...
