Air compressor to achieve a certain energy saving can also make the air compressor to achieve energy saving effect, Atlas air compressor manufacturers sorted out six kinds of energy saving schemes, you can use as a reference:
1, choose energy-saving motor。Compared with the ordinary motor, the overall design is optimized, and high-quality copper winding and silicon steel sheet are selected to reduce various losses, the loss is reduced by 20%~30%, and the efficiency is increased by 2%~7%;The investment payback period is generally 1 to 2 years, and some months。In contrast, the efficiency of the high-efficiency motor is 0. 0 higher than that of the J02 series motor.413%。Therefore, it is imperative to replace the old motor with an efficient motor。
2, appropriate selection of motor capacity to achieve energy saving。The state has made the following provisions for the three operation areas of the three-phase asynchronous motor: the load rate between 70% and 100% is the economic operation area;The load rate between 40% and 70% is the general operating area;The load rate below 40% is a non-economic operation zone。Improper selection of motor capacity will undoubtedly lead to waste of electric energy。Therefore, the use of appropriate motor, improve the power factor, load rate, can reduce power loss, save energy。3, using magnetic slot wedge instead of the original slot wedge。The magnetic slot wedge mainly reduces the no-load iron loss in the asynchronous motor, and the no-load additional iron loss is generated in the stator and rotor core by the harmonic magnetic flux caused by the tooth slot effect in the motor。The high frequency additional iron loss induced by stator and rotor in the core is called pulse vibration loss。In addition, the stator and rotor teeth are sometimes aligned and sometimes staggered, and the magnetic flux of the tooth cluster on the tooth surface changes, which can induce eddy currents in the tooth surface line layer and produce surface loss。Pulse vibration loss and surface loss are called high-frequency additional loss, they account for 70% to 90% of the motor stray loss, and the other 10% to 30% is called the load additional loss, which is generated by the leakage flux。Although the use of magnetic slot wedge will reduce the starting torque by 10% to 20%, the iron loss of the motor with magnetic slot wedge can be reduced by 60k compared with the motor with ordinary slot wedge, and it is very suitable for the transformation of the motor with no-load or light-load start。
4, using Y/△ automatic conversion device。In order to solve the waste of electric energy when the equipment is light loaded, Y/△ automatic conversion device can be used to achieve the purpose of power saving without replacing the motor。Because in the three-phase AC network, the voltage obtained by the different connections of the load is different, the energy absorbed from the grid is also different。
5, motor power factor reactive power compensation。The main purpose of reactive power compensation is to improve power factor and reduce power loss。The power factor is equal to the ratio of active power and apparent power, usually, the low power factor will cause the current to be too large, for a given load, when the supply voltage is certain, the lower the power factor, the greater the current。Therefore, the power factor is as high as possible to save energy。
6, winding motor liquid speed regulation。Liquid resistance speed regulation technology is developed on the basis of the traditional product liquid resistance starter。The purpose of stepless speed regulation is still to change the size of the plate spacing to adjust the resistance。This makes it have good starting performance at the same time, it is long-term power, bringing heating and heating problems, due to the use of a unique structure and reasonable heat exchange system, its working temperature is limited to a reasonable temperature。Liquid resistance speed regulation technology for winding motor，It has the advantages of reliable operation, easy installation, large energy-saving range, easy maintenance and low investment，It spread quickly，For some speed accuracy requirements are not high，The speed range is not wide，And do not frequently speed the winding motor，Such as fans, water pumps and other equipment of large and medium-sized winding asynchronous motors using liquid speed regulation effect is remarkable。
