Description

Technical Field

[0001] The utility model belongs to the field of compressors, and in particular relates to a centrifugal compressor with self-adjusting flow rate. Background Art

[0002] A centrifugal compressor is a common power mechanical device used to compress gas to a higher pressure state. It pushes the gas into a contracted space through the centrifugal force of high-speed rotation, where the pressure is increased. This type of compressor is commonly used in air compressors, refrigeration systems, and air conditioning systems.

[0003] When existing centrifugal compressors are used in industrial processing, the air intake volume of the compressor is often required to be adjusted to achieve energy saving and emission reduction under low efficiency because the air intake volume required by the compressor under different efficiencies is different. Existing compressors often control the opening and closing of the compressor air intake port through a throttle valve, and the structure of the throttle valve is limited, and it is usually difficult to flexibly and accurately control the air intake flow of the compressor, which greatly affects the power consumption of the compressor during use. In addition, the drive motor of the compressor is large in size, so it often produces large vibrations during use, which easily causes noise and affects the hearing of the user.

[0004] Therefore, in view of the problem that the above-mentioned centrifugal compressor is difficult to flexibly adjust its intake flow rate according to the needs of the compressor working efficiency, and it is easy to make loud noise when in use, a centrifugal compressor with self-adjusting flow rate is developed. By adding an intake regulating structure, a rotating ball valve processing and a shock-absorbing and buffering structure to the centrifugal compressor, the noise generated by the device when in use can be greatly reduced, and the intake flow rate of the compressor can be flexibly adjusted according to the needs of the user, thereby improving the energy-saving and emission-saving effects of the device. Utility Model Content
