Problems solved by technology

This bypass backflow delays the separation of rotor blade tip airflow and blockage of blade slots, and expands the stable working boundary of the compressor. The slots of the existing processing casing are linear, which cannot meet the installation angle of the front and rear slots. Different Design Requirements
In the implementation, the installation angle of the rear section is often the best, and the installation angle of the front section is not suitable; or a compromise is made between the two, which deviates from the optimal state, thus reducing the effect of expanding the stable working range of the processing box

Abstract

The present invention discloses a processor case with non-rectilinear slot on it and adopts banana-shaped structure or structure of linear that connected with arc segments. A compressor includes a processor case, rotor blade, stator blade, dish of wheel, stator inner loop and axis; the processor case includes organic case body and process ring, wherein one end of the stator blade connects with the stator inner loop and the other end connects with the organic case body; one end of the dish of wheel connects with the rotor blade while the other end connects with the axis; the process ring connects with the organic case body; the invention is characterized in that a process cavity is formed inside the case body and the process ring; the rotor blade rotates and air draft flows in from the process ring and circulates inside the process cavity, then flows out from the process ring. The present invention changes structure of traditional cases, improves performance, expands stable work margin of the processor case, and can be applied on aerial engine shaft pressured gas flow development work and has a broad application prospect.

Description

technical field [0001] The invention relates to the fields of machinery and gas dynamics, and in particular provides a processing casing and a gas compressor. Background technique [0002] The function of the compressor handling casing is to improve the stable working margin of the compressor. It is composed of slots evenly distributed in the circumferential direction around the outer casing of the rotor blade tip and a resident chamber outside the slots. The gas in the flow path of the compressor enters the cavity through the rear section of the slot, flows forward, and then flows back to the main flow through the front section of the slot. This bypass backflow delays the separation of rotor blade tip airflow and blockage of blade slots, and expands the stable working boundary of the compressor. The slots of the existing processing casing are linear, which cannot meet the installation angle of the front and rear slots. There are different design requirements. In the impl...
