The air pumps traditionally used in air boosting are: 1. Piston compressors, due to their complex structure and discontinuous exhaust, have the following disadvantages: large volume, low efficiency, loud noise, unstable operation, and oily, etc. Disadvantages, mainly used in industry; 2. Due to the difficulty of sealing, the rotary compressor has the disadvantages of high noise, low efficiency, and oil content, and is mainly used in the refrigeration industry
3. Centrifugal compressors have disadvantages such as low power, low efficiency, and high noise due to their surge characteristics and the limitation of motor speed, and their application range is small.
In addition, the traditional compressor motor has a low speed. In order to obtain a higher speed, an indirect connection method (such as a pulley or a gear) is used to increase the speed. Therefore, the structure is complex, the volume is large, and the efficiency is low.
Therefore, the traditional compressor is difficult to meet the requirements of the fuel cell engine for the air pump in the vehicle

Abstract
The invention discloses a combination pump of a mechanical turbine. The combination pump is characterized by comprising a turbine compressed air assembly, a speed increaser, a high-speed motor and a controller; the turbine compressed air assembly is connected to the speed increaser; the motor and the speed increaser are coaxially and directly connected by adopting a coupler; and the controller is connected with the motor by a signal wire. The combination pump can be applied to a wind supply system of a fuel cell of a new-energy automobile, overcomes the constraint bottlenecks of the traditional air pump in the aspects of pressure, flow, efficiency, noise, vibration, cleaning and volume, and has wide prospects and favorable social and economic benefits in the application of new energy sources.
Description
technical field [0001] The invention relates to the technical field of air compressors, in particular to an air booster combined pump used in occasions where air needs to be boosted. Background technique [0002] In some special applications (such as vehicle fuel cell gas supply system), the air compressor requires a large flow volume ratio, clean output gas without oil, high efficiency, low noise, high response, long service life, etc. The air pumps traditionally used in air boosting are: 1. Piston compressors, due to their complex structure and discontinuous exhaust, have the following disadvantages: large volume, low efficiency, loud noise, unstable operation, and oily, etc. Disadvantages, mainly used in industry; 2. Rotary compressors, due to the difficulty of sealing, have the disadvantages of high noise, low efficiency, and oil, and are mainly used in the refrigeration industry. 3. Centrifugal compressors have disadvantages such as low power, low efficiency, and high ...
