First principle conversion type air compressor Transformation: frequency converter, pressure transmitter, motor, screw rotor and other equipment pressure closed loop automatic control motor speed control system, so that the gas tank air pressure stable in the set range, the constant pressure control. Through the comparison of the feedback pressure and the set pressure, the output of the inverter can be controlled in real time, so as to adjust the speed of the motor, and the air pressure in the gas storage tank is stable on the set pressure.

Talk about the benefits of frequency conversion:

1, saving energy

Comparison of air compressor air compressor inverter control and traditional control, energy saving is the most meaningful, Zhenhui air compressor air condition according to the demand to supply is the most economical.

According to the 24 hours a day, a year to run the calculation of the day, when the electricity saving rate of 5%, a year can save electricity 37*5%*24*360=15984 degrees, each power level of 0. 5 yuan, a year can save $7992 a year and a half to recover investment. When the electricity saving rate of 20%, a year saving 63936 degrees, saving $31968, six months to recover investment.

2, reduce operating costs

The operation cost of the traditional compressor is composed of three parts: initial purchase cost, maintenance cost and energy cost. The energy cost accounts for about 77% of the compressor running cost. By reducing the cost of energy 10%-40%, coupled with the frequency conversion after the impact of the device to reduce the maintenance and maintenance of the volume also follow the reduction, so the operating costs will be greatly reduced.

3, to improve the accuracy of pressure control

Variable frequency control system with accurate pressure control. The air pressure output of the compressor is matched with the air quantity required by the user air system. The output gas of the inverter control compressor changes with the change of motor speed. Because of the precision of frequency control motor speed, so it can make the pressure change in the pipe network in the 3pisg range of change, that is, 0.2bar range, effectively improve the quality of the working conditions.

4, extend the service life of the compressor

Starting from 0HZ inverter compressor, soft start Zhenhui air compressor, no peak current, smooth start; its starting time can be adjusted, thereby reducing the electrical and mechanical parts of the compressor start impact, enhance the reliability of the system, to prolong the service life of compressor.

5, the noise of the air compressor

According to the requirements of the working condition of the compressor, the speed of the motor is obviously slowed down, so the noise of the compressor can be reduced effectively.

In the constant pressure control system, the inverter will according to the network instantaneous consumption changes and automatically adjust the speed of the running number of air compressor air compressor station, the pipeline pressure keeps constant pressure, so as to achieve the energy saving of air compressor consumption and improve the supply quality, and realize the automatic control process, and to Zhenhui inverter compressor of overpressure, overload, overcurrent, undervoltage protection, automatic alarm.
