Lubrication enhancing slip sheet for rolling rotor compressor

Abstract

The invention discloses a lubrication enhancing slip sheet for a rolling rotor compressor. The slip sheet comprises a slip sheet body. The bottom of the slip sheet body is a smooth curve. A transverseairflow channel and a longitudinal airflow channel which are communicated are arranged inside the slip sheet body, the transverse airflow channel forms a high pressure side exhaust opening and a lowpressure side exhaust opening at the two friction faces of the slip sheet body, the end, away from the transverse airflow channel, of the longitudinal airflow channel is bent towards one side of the friction face where the high pressure side exhaust opening is formed and forms a high pressure air inlet, and the portions, corresponding to the high pressure side exhaust opening and the low pressureside exhaust opening, of the slip sheet body are each provided with an outlet groove. High pressure gas containing oil mist in the high pressure cavity of the compressor is introduced into a gap between the limiting groove and the slip sheet through the transverse airflow channel and the longitudinal airflow channel of the slip sheet, the lubricating effect of the slip sheet is enhanced, the mechanical efficiency of the compressor is improved, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of sliding vanes, in particular to an enhanced lubricating sliding vane for rolling rotor compressors. Background technique [0002] As the core component of the air conditioning system, the compressor completes the cooling or heating operation by compressing the refrigerant from the low pressure area to the high pressure area. With excellent performance, the rolling rotor compressor occupies a large proportion in small and medium power air conditioners. The rolling rotor compressor drives the eccentric rotor to rotate by the electric motor. Continuously compress the gas in the low-pressure chamber to the high-pressure chamber and discharge it through the exhaust valve. When the rotor rotates, the sliding vane reciprocates in the limit groove of the cylinder under the action of the rotor and the spring force. When the slider is moving at high speed, due to the small gap between the limit groove and the sli...

AI Technical Summary

Problems solved by technology

When the slider is moving at high speed, due to the small gap between the limit groove and the slider, the lubrication conditions are poor, and heat is generated. At the same time, there is mixed friction or even dry friction between the slider and the cylinder, resulting in the sliding and The wear of the limit groove of the cylinder is intensified, and in severe cases, the gap between the two will increase, which will eventually lead to the jamming of the sliding vane and the rotor, which will eventually affect the mechanical efficiency
