Embodiment 1

[0033] When the existing processing casing is applied to the compressor, it does not help much to improve the compressor surge phenomenon and the stability margin of the compressor. With the development of time, the gas turbine requires the compressor to have a high pressure ratio and a high load. How to improve the stability margin of the compressor has always been a difficult problem restricting the performance improvement of the gas turbine. Therefore, a solution different from existing processing casings is urgently needed.

[0034] Such as Figure 1-Figure 5 As shown, a slanted hole type processing casing includes a casing body 1 and several air holes 2 arranged on the casing body 1, that is, the present invention provides a slanted hole type processing casing, which uses the air holes 2 to guide The blocked gas on the flow channel of the compressor pushes the blocked gas below to flow to the rear of the flow channel, reducing the influence of the blocked gas on the flow...

Embodiment 2

[0056] In this embodiment, on the basis of embodiment 1, the use of the inclined-hole processing casing described in embodiment 1 is described: a compressor includes the above-mentioned inclined-hole processing casing.

[0057] Through the oblique hole processing casing with simple structure and good workmanship, the gas above the compressor flow channel is sucked into the additional chamber 4, and then sprayed out to push the stagnant gas under the flow channel to replenish the active flow and improve the entire flow. The blockage of the channel makes the gas flow in the channel more smooth. In this way, it not only reduces the influence of stagnant gas on the stability of the flow channel, but also improves the utilization rate of the gas, reduces the negative impact of the compressor due to the change of the rotational speed, and can greatly improve the performance of the compressor. Stability margin.

Abstract

The invention belongs to the technical field of processing casings, and in particular relates to an oblique hole type processing casing and a compressor, wherein, an oblique hole type processing casing includes a casing body and several air holes arranged on the casing body, Wherein, the inner side of the casing body is provided with a compressor, and the outside of the casing body is provided with an outer casing, and the outer casing is buckled on the casing body and forms an additional cavity between the two; the air hole runs through the casing body and The inner side of the casing body is connected with the additional cavity, so that the gas inside the casing body circulates through the additional cavity. An air compressor, comprising the oblique hole type processing casing. A slant-hole processing casing and compressor use the pores to guide the blocked gas on the compressor flow channel, and push the blocked gas below to flow to the rear of the flow channel, reducing the influence of the blocked gas on the flow field characteristics of the compressor , to increase the stability margin of the compressor. At the same time, the slanted hole processing casing has the characteristics of low technological requirements, low processing cost and high applicability.

Description

technical field [0001] The invention belongs to the technical field of processing casings, and in particular relates to an oblique hole type processing casing and an air compressor. Background technique [0002] A compressor is a machine that works on the airflow through rotating blades to increase the pressure of the airflow. The front part of the impeller blade of the compressor is curved and called the guide wheel, and its function is to guide the gas into the working impeller without impact and reduce the impact loss of the air flow. The compressor impeller of the small supercharger generally integrates the guide wheel and the working impeller. There is a diffuser at the outlet of the impeller of the compressor, so that the kinetic energy obtained by the gas in the impeller can be converted into pressure as much as possible. The casing of the compressor has inlets and outlets for airflow. The inlet is generally arranged axially, and the flow channel is slightly tapere...
