Oil-injected horizontal scroll air compressor

Abstract

The invention discloses a horizontal vortex air compressor for oil injection, which comprises an oil gas barrel, a cooler, an oil filter and a host part, wherein the oil gas barrel is connected with the host part, the cooler is connected with the oil gas barrel, the cooler is connected with the host part through the oil filter, the host part comprises a frame, a spindle, a rotary vortex part and a fixed vortex part, the fixed vortex part is provided with an exhaust passage and an air suction passage, the horizontal vortex air compressor for oil injection is characterized in that a supporting component capable of supporting the rotary vortex part movably is arranged between the opposite side of a scroll of the rotary vortex part and the frame, the supporting component pushes the rotary vortex part to be always tightly jointed with the fixed vortex part in a moving process under the action of the pressure at the back side, and the rotary vortex part and the fixed vortex part are axially sealed through the supporting component. According to the invention, the leakage phenomenon of a compression chamber through a tiny clearance can be completely solved, efficiency and performance of the compressor are improved, the quality of the air at the air outlet is enhanced, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to the technology of oil-injected horizontal scroll air compressors. Background technique [0002] The orbiting scroll of the scroll air compressor and the scroll of the fixed scroll mesh to form multiple compression chambers. During the movement of the orbiting scroll, each compression chamber gradually shrinks and moves to the middle, thereby realizing the compression of gas , and finally discharged through the exhaust port opened in the center of the fixed scroll. [0003] Such as figure 1 , when the air is compressed in the compression chambers, the pressure inside each compression chamber gradually increases, generating a force that axially separates the orbiting scroll 102 from the fixed scroll 101 . In a general scroll air compressor, in order to prevent the axial separation of the orbiting scroll 102 and the fixed scroll 101, a support portion 105 supporting the en...

AI Technical Summary

Problems solved by technology

However, the thickness of the oil film produced by the sprayed lubricating oil is not enough to make up for the above-mentioned small gap. The leakage of each compression chamber in the upper part of the compressor is intensified, and the problem of reduced efficiency of the compressor has not been completely improved

In the case of increasing the amount of lubricating oil injected, the burden on the oil-air separator is increased, and the separation effect of the oil-air separator on the oil droplets contained in the air is reduced, resulting in a decrease in the quality of the air at the air outlet. cause environmental pollution
