1, the power consumption of ordinary air compressor is seriously wasted, and energy is mainly wasted in the following aspects:
1) the power consumption at loading time:
After the pressure reaches the required working pressure, the normal control mode determines that the pressure will continue to rise until the unloading pressure. During the pressurization process, more heat and noise will be generated, resulting in the loss of electric energy. On the other hand, the pressure of a high-pressure gas before it enters a pneumatic component or equipment needs to be reduced by a pressure reducing valve, which also requires energy consumption.
2) power consumption during unloading:
When the unloading pressure is reached, the air compressor opens the unloading valve automatically, making the motor idle, causing serious energy waste. The power consumption of the air compressor during unloading accounts for about 30%-50% of the full load. It can be seen that the traditional air compressor has obvious energy-saving space.
2, the consumption of power frequency startup power:
Although the main motor of air compressor is started by Y - delta voltage reduction, the starting current is still very large, which will easily cause instability of power grid and threaten the operation safety of other electrical equipment. For self power plants, several times the rated current impact may lead to other equipment abnormalities.
3, the pressure is unstable, the degree of automation is low.
The traditional air compressor has a low degree of automation, and its output pressure is regulated by controlling the loading and unloading valves and regulating valves. The regulating speed is slow, the fluctuation is large, the precision is low, and the output pressure is unstable.
4, equipment maintenance is large.
Air compressor power frequency starting current is large, up to 5 ~ 8 times rated current, working mode determines the loading and unloading valve must be repeated action, components easy to aging, power frequency high-speed operation, bearing wear, equipment maintenance.
5. Loud noise.
Continuous high-speed operation of power frequency, excessive pressure over the required working pressure, repeated loading and unloading, will directly lead to high noise in power frequency operation.
