Problems solved by technology

[0009] However, the above structure has the following disadvantages: when the gas rotating at high speed with the impeller 20 passes through the end of the baffle plate v in a static state, the baffle plate interacts with the pressure generated by the flowing gas, which not only produces high-frequency noise, but also passes through the baffle plate v. The gas flowing between v and the baffle v is unstable, so isolation occurs at the end of the baffle v, narrowing the actual passage through which the gas can flow
[0013] Although the tubular diffuser body 40 of this structure has superior performance, because the plurality of scraping channels 41 formed through the diffuser body 40 not only form a certain inclination angle, but also have different cross-sectional sizes of each part, it is difficult to process and increases the cost. manufacturing cost

Embodiment Construction

[0026] The diffuser structure of the turbocompressor of the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments: Figure 4 Shows a turbocompressor compression part provided with a diffuser structure of the turbocompressor proposed in the present invention. The compression part of the turbocompressor is provided with a compression chamber 10 penetrating with the suction passage F inside the housing 100 , and a rotatable impeller 20 is inserted into the compression chamber 10 . The impeller 20 is connected to a motor provided inside the housing 100 through a rotating shaft 30 .

[0027] The compression chamber 10 is composed of the following structures: an inducing impeller 1 connected through the suction channel F to allow gas to enter, an impeller insertion space 2 connected to the inducing impeller 1 and capable of being inserted into the rotating impeller 2, and a volute 4 formed around the impeller ins...

Abstract

A diffuser structure of turbine compressor is composed of inducing vane wheel, vane wheel, channel, spiral casing, casing, and the main body of diffuser, which is positioned in the channel to communicate the vane wheel space with spiral casing. The ring-shaped main body has a certain thickness and width. Multiple open channels in the diffuser are connected to the internal and external surfaces of its main body. It can improve the gas compressing performance of turbine compressor.

Description

technical field [0001] The invention relates to the field of turbo compressors Background technique [0002] Generally speaking, compressors for compressing fluids are divided into the following types according to their compression methods: rotary compressors, reciprocating compressors, scroll compressors, turbo compressors, etc. The compressor is composed of a closed container, a motor installed inside the closed container to generate driving force, and a compression part that compresses gas using the driving force of the motor. [0003] In a turbo compressor, an impeller rotated by an electric motor is located in the compression chamber, and gas is sucked in and compressed by the rotation of the impeller. [0004] figure 1 The compression part of the turbo compressor is shown. As shown in the figure, the compression part of the turbo compressor is provided with a compression chamber 10 which is connected through a suction passage F inside the shell 100 . A rotatable imp...
