Abstract

The invention relates to the technical field of electromechanical equipment and compressors and provides a roller compressor of a novel structure. The roller compressor is characterized in that an outer ring sleeve and an inner ring sleeve in a compressor shell are arranged concentrically, a roller is arranged between the outer ring sleeve and the inner ring sleeve, the roller is tangent with theinner wall of the outer ring sleeve and the outer wall of the inner ring sleeve at the same time, a swing column is arranged in an arc surface groove between the outer ring sleeve and the inner ring sleeve, the outer ring sleeve or the flowing-in end of the compressor shell is provided with a main air inlet, an air inlet is formed in the portion close to the flowing-in end of the roller, the flowing-out end of the roller is provided with an exhausting hole and a one-way valve, the outer ring sleeve or the flowing-out end of the compressor shell is provided with an exhausting hole and a one-wayvalve, and the flowing-out end of the compressor shell is provided with a main exhausting opening. The roller compressor can be widely applied to an air compressor, a natural gas compressor, an air blower, a refrigerating compressor, an air source heat pump compressor, a vacuum pump, an oil conveying pump, a pneumatic motor, a hydraulic motor and the like.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, and relates to a positive displacement compressor, in particular to a compressor and a pump, such as an air compressor, a refrigeration compressor, a heat pump compressor, a vacuum pump, and an oil delivery pump. It can also be used as air motor or hydraulic motor. Background technique [0002] At present, the more commonly used compressors are piston compressors, rolling rotor compressors, screw compressors and scroll compressors. The main disadvantages of piston compressors are: large inertial force and low speed, so the machine is relatively heavy, especially when the displacement is large, and the vibration of the whole machine is large. The structure is complicated, there are many wearing parts, and the maintenance workload is heavy. Discontinuous exhaust, air pressure pulsation, easy to produce air column vibration. The noise is loud, so it can only be placed outdoors...

AI Technical Summary

Problems solved by technology

The main disadvantages of piston compressors are: large inertial force and low speed, so the machine is relatively heavy, especially when the displacement is large, and the vibration of the whole machine is large

Loud noise, can only be placed outdoors to isolate noise

The main disadvantage of the rolling rotor compressor is that there is a lot of residual gas after the compression, and the volumetric efficiency is low. Once the structure of the fixed center distance is worn, there will be obvious leakage between the rotor and the cylinder wall, which limits its working life and efficiency improvement

The main disadvantages of the screw compressor are: complex helical surface processing is difficult, equipment investment is large, cost is high, production efficiency is low, the precision of the helical surface profile is low, the contact area of ​​the sealing line is small, the sealing performance is poor, and lubricating oil is required for cooling and sealing , the exhaust system needs an oil and gas purifier, and the auxiliary system is complex

However, the scroll compressor requires a complex positioning system, and its complex scroll surface is difficult to process, and the equipment required is large in investment, high in cost, and low in production efficiency, which cannot meet market demand.

The current exhaust method of the concentric ring roller compressor is to rely on the upper part of the pendulum to communicate with the exhaust hole on the top of the casing for exhaust. The pressure of the exhaust port acts on the pendulum to compress the inner ring sleeve, resulting in a large Pressure and resistance will accelerate the heating and wear of the pendulum, and it is also easy to leak air from the top gap

In addition, the rounded corners inside the drum are difficult to process, which makes it difficult to guarantee the sealing performance and the manufacturing cost is also high
