As we all know, air compressors are widely used in industrial production. In factories of all walks of life, they are responsible for supplying air to the factory and providing air sources for all pneumatic components. As a large-scale industrial equipment, the air compressor itself consumes a lot of electricity. In many factories, it accounts for 20% of the electricity consumption. It is a veritable electric tiger. The purpose of air compressor energy-saving transformation is to reduce air compressor energy consumption and save air compressor operating costs for enterprises.

  1. Energy-saving transformation of air compressors is imperative

 

In fact, the air compressor does not need continuous power supply to work all the time. The air compressors in most factories are running continuously, because the motor itself of the general air compressor cannot slow down according to changes in pressure demand, so that the motor output power matches the actual pressure demand on site. This is As a result, the air compressor still has to run without load when the air consumption is small, which causes a huge waste of electrical energy. Moreover, traditional air compressors use star-delta step-down starting, but when starting at power frequency, the current can still reach 6 to 7 times the rated current, causing a large impact and affecting the stability of the power grid.

  1. Frequency conversion energy saving

 

The power supply frequency is adjusted through the frequency converter, and the gas production volume of the compressor is reduced by reducing the rotation speed, so that the gas network pressure is constant within a certain range to meet the gas consumption standard, thereby achieving energy saving. The disadvantage of using this method is that the frequency converter needs to be replaced regularly, and when the gas loading rate is above 80%, the frequency converter itself will lose energy, and the energy consumption will be higher at this time.

This energy-saving method is to use the air compressor to stop the machine when unloading, saving power consumption during shutdown. At present, the most common air compressor power saver on the air compressor market – air compressor energy-saving drive all-in-one machine, with a small starting current, can maximize the air compressor while protecting the motor and machine head and ensuring the user’s safe air consumption. Unloading and downtime save energy.

  1. Permanent magnet frequency conversion energy saving

In terms of the energy-saving method of the frequency converter, the motor is upgraded to a permanent magnet electromechanical, and the motor efficiency is increased by 7%-9%, further improving the energy-saving rate based on the energy saving of the frequency converter. The price of a permanent magnet motor is about 1.5 times that of a variable frequency motor and about 2 times that of an ordinary motor. The initial cost will be higher.

 

Therefore, before carrying out energy-saving transformation of air compressors, you must pay careful attention, ask and check more, and find the most suitable transformation method.
