Air compressor industry power saving application scheme

For the power-saving application scheme of the air compressor industry, this article mainly summarizes from two aspects, one is the working principle of the air compressor, and the other is an overview of the power-saving application scheme of the air compressor industry.

The working principle of the air compressor: the compressor is directly driven by the electric motor to make the crankshaft rotate, and the connecting rod is driven to make the piston reciprocate, causing the cylinder volume to change. Due to the change of the pressure in the cylinder, the air enters the cylinder through the air filter (muffler) through the intake valve. During the compression stroke, due to the reduction of the cylinder volume, the compressed air passes through the exhaust valve, and passes through the exhaust pipe. The direction valve (check valve) enters the air storage tank, and when the exhaust pressure reaches the rated pressure of 0.7MPa, it is controlled by the pressure switch and automatically stops. When the pressure of the air storage tank drops to 0.5--0.6MPa, the pressure switch is automatically connected and activated.

Air compressor industry power saving application scheme:

Compressors include air-conditioning and refrigeration mainframes and air compressors. Their operating characteristics are that they operate continuously 24 hours a day under two conditions of loading and unloading, and do not stop 365 days a year. One of the most power-consuming motors ;At present, the constant voltage control method adopts two control methods: speed regulation and non-speed regulation.

No speed control.
