The Way of Energy Saving for Air Compressor

An air compressor to solve gas leak and ways to save energy

First, the air compressor means to solve the gas leak and can save energy. According to authoritative testing, only the energy consumed by air compressor

10% converted to compressed air, while 90% converted to heat, electricity you can see ten times more than compressed air. However, in the minds of most people do not realize this, and it mainly as follows:

1.1 does not attach importance to management way of leakage in the trachea is a hidden leak first occurred, and only then were missing. When sending trachea hole 1 mm appears, the compressed air pressure 0.714Mpa, the leakage was 1.5 L / s, equivalent to loss of power of the compressor 0.4 kW. However, in most of the factories, everywhere can hear the voice of leaks, who go into it? Because there is no recognized power of your compressed air than ten times, so are used to it. Therefore, the air compressor energy to do the first leak is good governance.

1.2 The waste caused by improper use just one example here, the circuit board manufacturers, most of the plating line to be used for vibration to increase the capacity of the hole plating, and some manufacturers prefer use of air vibration to achieve this, everyone knows that make use of electronic vibration than a way to consume ten times more electricity. Through Table 1 to vibration and electrical vibration of the air to make a comparison between the pros and cons. From Table 1 we can see the air vibrating access to more than one media, and access to compressed air consumption is so large, and therefore vibration of energy than gas electric vibration is not surprising that more large. Therefore, energy-efficient air compressor while also avoiding improper use of gas way. Second, to take energy-saving technology can save energy.

Second, the way for energy saving compressor

Currently, energy-saving air compressor for a total of three methods, test set as follows:

2.1 centralized control

To focus on the multiple compressor control method. Situation under control with a gas station air compressor to run the number of transformation before the station opened a few compressors is fixed.

(1) When reduced to a certain amount of gas when the compressor is to reduce the load time by reducing gas production.

(2) If further reduction of gas consumption, performance, good air compressor will automatically shut down. In (1) of the case, the compressor even in the unloaded case is to consume electricity. After the transformation, will be turning off the corresponding number of compressor units, reducing the number of operating units, and will undoubtedly save electricity.

2.2 Frequency mode

Frequency approach taken to reduce air compressor motor shaft power output. Transformation before the pressure reaches the set pressure of the air compressor, which is automatically unloading; transformation, the compressor is not unloading, but by reducing the compressor speed to reduce the time of gas production, gas network needs to maintain minimum pressure. There are two places to energy conservation:

(1) reduce the compressor from unloading to loading state the power consumption caused by mutations in the process.

(2) lower motor operating frequency to frequency below the motor shaft output power reduction. Not more than two ways
