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] like 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 fi...

Embodiment 2

[0056] In this embodiment, on the basis of embodiment 1, the use of the oblique-hole processing casing described in embodiment 1 is described: a compressor includes the above-mentioned oblique-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 treatment casing, and particularly relates to an inclined hole type treatment casing and a gas compressor, the inclined hole type treatment casing comprises a casing body and a plurality of gas holes formed in the casing body, the gas compressor is arranged on the inner side of the casing body, an outer casing is arranged on the outer side of the casing body, and the gas holes are formed in the gas holes. The outer casing is buckled on the casing body, and an additional cavity is defined between the outer casing and the casing body; the air hole penetrates through the casing body and is communicated with the inner side of the casing body and the additional cavity, so that air on the inner side of the casing body circularly flows through the additional cavity. The gas compressor comprises the inclined hole type treatment casing. According to the inclined hole type treatment casing and the air compressor, the air holes are used for guiding unblocked air on the flow channel of the air compressor and pushing the unblocked air below to flow towards the rear part of the flow channel, so that the influence of the unblocked air on the flow field characteristics of the air compressor is reduced, and the stability margin of the air compressor is improved. Meanwhile, the inclined hole type treatment casing has the advantages of being low in process requirement, low in machining cost and high in 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...
