Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and examples, but not as a limitation to the present invention.

[0018] exist figure 1 In the shown structure, a kind of centrifugal counter-rotating ram compressor designed by the present invention includes an intake system, a transmission device, an impeller and a casing 5; the intake system mainly includes a gas filter device, an intake fairing 3, an inlet Air flow control device, guide wheel, etc., according to the needs, the air intake system and the impeller can be integrated into the design of the small compressor. The transmission device can be set according to specific application requirements, including connecting parts, shafts, speed change mechanisms, etc., which can realize the matching of the speed of the power device and the rotating parts (such as impellers, etc.). The impeller is a circular rotating part, which can be open or closed. It is composed of a...

Abstract

The invention belongs to the technical field of gas supercharging and relates to a centrifugal contra-rotating ram compressor which comprises a gas inlet system, a transmission device, an impeller and a housing, wherein a punching wheel which reversely rotates along with the impeller is arranged on a position, at the radial outer side of the impeller, between the impeller and a pressure expander or between the impeller and a gas collecting tube; and the punching wheel and the impeller are separately connected with a power device through the transmission device. According to the centrifugal contra-rotating ram compressor, the punching wheel is arranged in a gas flow channel for further supercharging gas, so that gas pressure higher than that of an existing centrifugal compressor can be obtained, and therefore, a pressure ratio is effectively increased, efficiency of the compressor is improved, and the range of application of the compressor is expanded.

Description

technical field [0001] The invention belongs to the technical field of gas boosting, and relates to a compressor, in particular to a centrifugal counter-rotating stamping compressor. Background technique [0002] In a broad sense, a compressor generally refers to a mechanical device that can increase the gas pressure. It works on the gas through a mechanical device to increase the gas pressure. It is used for pneumatic equipment, tire inflation, painting, spraying, plasma cutting, pneumatic tools, etc. It is widely used in various industries. [0003] At present, there are many types of compressors, which are mainly divided into two categories: positive displacement type and rotor power type. Increase the speed of the gas to increase the dynamic pressure of the gas, and then convert the dynamic pressure into static pressure; the positive displacement compressor is divided into piston type, diaphragm type, scroll type, screw type compressor, etc., and the rotor power type co...
