1. The frequency conversion speed regulation method adopts the frequency conversion speed regulation method to reduce the shaft power output of the air compressor motor. Before the transformation, when the pressure of the air compressor reaches the set pressure, it will automatically unload; after the transformation, the air compressor will not unload, but reduce the gas production during the compressor by reducing the speed, and maintain the required air network. minimum pressure. Here are two places to save energy:
(1) Reduce the power consumption caused by the sudden change of the compressor from the unloading state to the loading state.
(2) The operating frequency of the motor is reduced to below the power frequency, which reduces the output power of the motor shaft. Both of the above two methods reduce the energy consumption of the air compressor during operation to varying degrees, but the air compressor generates such a large amount of heat energy during the working process that it is dissipated into the air in vain, but in a very long time It cannot be said that it is not a great pity that it has not received the general attention of users within a period of time.
2. Centralized control method
Adopt centralized control mode for multiple air compressors. The number of air compressors is automatically controlled according to the gas consumption. Before the transformation, the number of air compressors turned on is fixed.
(1) If the air consumption is further reduced, the air compressor with good performance will automatically stop. In the case of (1), the air compressor consumes electricity even when it is unloaded. After the transformation, the corresponding number of air compressors can be stopped, and the number of operating units is reduced, which undoubtedly saves electricity.
(2) When the gas consumption is reduced to a certain amount, the air compressor reduces the gas production by reducing the loading time.
3. Air compressor heat recovery
Air compressor heat recovery is a very environmentally friendly way to save energy.
How heat recovery device works
The high-temperature oil of the air compressor transfers heat to the cooling water through the heat exchanger, and the cooling water is heated and then flows into the heat preservation water storage tank, so that the purpose of heat energy recovery can be achieved.
4. Using the air compressor energy-saving controller, this product is developed with high-quality materials and components and the latest microcomputer fuzzy control technology. And it has the functions of multi-channel collection of air compressor temperature and ambient temperature as well as customer gas consumption, automatic identification and control of downtime and other functions.
