Analysis on Energy Saving of Air Compressor

An air compressor is a device that uses an electric motor to compress gas in a compression chamber and make the compressed gas have a certain pressure. In various industries, it is responsible for providing air source for all pneumatic components and various pneumatic valves in the factory. The largest energy consumption of air compressors is electrical energy consumption, which accounts for 77% of the total consumption, followed by maintenance costs, which account for 18% of the total consumption, while equipment investment only accounts for 5% of the total cost. The power consumption of the air compressor is amazing. An air compressor can cost as little as tens of thousands of yuan, and as many as millions, but the purchase cost is only 5%, which shows that its power consumption figures are huge. Therefore, only by finding the reason for the energy consumption of the air compressor and solving it in a targeted manner, energy efficiency can be improved. rate of compressor

The main aspects of air compressor energy consumption:

1. Control method: Since the air compressor does not rule out the possibility of running for a long time under full load, the motor capacity can only be determined according to the maximum demand when selecting the model, which causes the air compressor system margin to be generally too large. Traditional air compressors use star-delta step-down start, but the current can still reach 2 to 3 times the rated current when the power frequency starts, and the impact is large, which will affect the stability of the power grid. Moreover, most air compressors run continuously. As the motor of general air compressors cannot achieve speed reduction according to changes in pressure demand, the motor output power matches the actual pressure demand on site, resulting in a low air consumption. To run without load, resulting in a huge waste of electrical energy. According to statistics, air compressors account for almost 15% of the power consumption of large industrial equipment (fans, water pumps, boilers, etc.). Problems with the control method of loading and unloading air supply; through energy consumption analysis, the control method of loading and loading makes The pressure of the compressed gas changes back and forth between Pmin~Pmax, and Pmin is the lowest pressure value, that is, the lowest pressure that can ensure the user's normal work. Under normal circumstances, the relationship between Pmin and Pmax can be expressed by the following formula: CP max=(1+8) Pmin is a percentage, and its value is roughly between 10% and 25%. If frequency conversion technology is used If the air supply volume can be adjusted continuously, the pressure of the pipe network can always be maintained at a sufficient air supply pressure, that is, near Pmin. It can be seen that the energy wasted by the air compressor under the control mode of loading and unloading air supply is mainly in two parts (rate of compressor):

(1) The energy consumed when the compressed air pressure exceeds Pmin. After the pressure reaches Pmin, the original control method determines that its pressure will continue to rise (until Pmax). This process is also an energy-consuming process.

(2) Adjust when unloading The energy consumed by the unreasonable method. Normally, when the pressure reaches Pmax, the air compressor reduces the pressure and unloads by the following method: close the intake valve to make the motor in an idling state, and at the same time pass the excess compressed air in the separation tank through the vent valve Vent, this adjustment method will cause a big energy wave.

2. Gas leakage: only 10% of the electric energy consumed by the air compressor is converted into compressed air, and the remaining 90% is converted into heat energy. It can be seen that compressed air is ten times more expensive than electricity, but often we all ignore it. With this in mind, in most factories, the sound of air leakage can be heard everywhere, but no one pays any attention. This kind of leakage not only increases noise, but more importantly, leakage causes energy waste and reduces air output. Increased costs, large needles, large winds, and leakage, especially pipeline leakage, will save a lot of energy if the leakage problem is solved. rate of compressor
