Description

technical field [0001] The invention belongs to the field of air compression equipment, and in particular relates to a hybrid-driven air compressor. Background technique [0002] An air compressor is a device that uses a motor to compress gas in a compression chamber and make the compressed gas have a certain pressure. Air compressors provide air sources for all pneumatic components in factories, especially in textile, chemical, power and other industrial fields, which have become essential key and core equipment, especially screw air compressors are widely used in almost all industrial fields , Become the mainstream product of compressed air. However, the energy consumed by the air compressor is huge.

Problems solved by technology

However, the energy consumed by the air compressor is huge. At present, although the frequency converter is used to control the air compressor, the speed regulation performance of the air compressor is improved and the energy consumption is reduced, but in terms of response speed, energy recovery, peak load, etc. there are still shortcomings

There are several deficiencies in the existing air compressors: the power required by the air compressor is very large, which makes the volume of the main drive motor in the air compressor large, and the reasonable amount of the main drive motor inside the air compressor The layout becomes inconvenient, or even impossible, and the air compressor sometimes needs to be in low-speed and high-torque operating conditions. Due to the constraints of the current motor output torque, it is necessary to add a reducer to realize this function, which makes the main motor as a whole. The volume is further increased; the main motor of the air compressor is controlled by a frequency converter, the response of the starting and braking process is slow, and it takes a long time to complete; the main motor needs a lot of power when starting, and the working process starts and stops frequently. The service life of the main motor is greatly reduced, and when the air compressor brakes, its kinetic energy is often converted into heat energy, resulting in a large energy waste; the air compressor will have a peak load when starting or working, which will make the main The motor generates a lot of current and heat in a short time, which seriously damages the main motor and reduces the service life of the main motor
