After March, more and more topics have been talked about energy conservation and environmental protection. Even if there is no hard document issued by the central government, energy conservation and emission reduction should be the responsibility of every enterprise and every citizen. In order to fulfill our commitment to energy conservation and emission reduction to the world, we have taken a series of measures to increase energy conservation and emission reduction, including air compressors for high-power consumption equipment.

However, due to the continuous update and application of new technologies in the direction of energy conservation and emission reduction, the potential of ZEGA screw air compressor equipment in energy conservation has been gradually tapped.

　　Ruisheng electromechanical air compressor mainly promotes energy-saving and silent ZEGA screw air compressor, has done air compressor energy-saving solutions for many energy-consuming enterprises, with unique core technology and many years of energy-saving industry operation experience, service organizations all over the country. The following Ruisheng Electromechanical analyzes the operating principle and performance characteristics of the power-saving system of the air compressor:

　　Operation principle of ZEGA screw air compressor power-saving system:

　　In view of the many problems existing in the traditional air compressor air supply control method, the application of intelligent power-saving protection system for constant pressure air supply control is a good choice. When adopting this scheme, the pressure of the pipe network is taken as the control object, and the pressure transmitter YB converts the pressure P of the gas tank into an electrical signal and sends it to the PID intelligent regulator, compares it with the pressure setting value P0, and calculates according to the size of the difference according to the established PID control mode, generates a control signal and sends it to the intelligent power-saving protection system, and controls the output power of the motor through the system, so that the actual pressure P is always close to the set pressure P0. At the same time, the scheme can increase the mains and power-saving switching function, and retain the original control and protection system, in addition, after adopting the scheme, the air compressor motor from static to rotating work can be soft start by the power-saving system, avoiding the starting impact current and the mechanical impact of starting to the air compressor.

　　Performance characteristics of air compressor power-saving system:

　　(1) The power factor is increased from 0.7~0.8 to more than 0.96, which greatly reduces the reactive current, reduces the line loss, and improves the quality of the power grid and the efficiency of power supply. For power supply equipment, it is equivalent to playing a role in increasing capacity;

　　(2) Soft start, smooth starting without impact. On the one hand, this can reduce the impact on the motor and the power grid when starting, which not only protects the motor, prolongs its service life, but also increases the installed capacity of the system for the power grid;

　　(3) Make the upper and lower limit control mode of air compressor pressure into constant pressure control, so that the output of the air compressor system accurately matches the required power, reduces the unnecessary high energy consumption loss in areas with high pressure, avoids inefficient working state when unloading or no-load operation, and the power saving rate can reach 10~30%;

　　(4) There is no need to adjust the power-saving equipment in production, the whole process is automatically tracked and controlled, and there are a variety of (overcurrent, overload, overvoltage, underage, etc.) protection functions, which are simple, safe and convenient;

　　(5) THE EQUIPMENT NOISE IS REDUCED BY ABOUT 10DB, THE EQUIPMENT ACTION IS MORE STABLE, AND THE ENVIRONMENT IS IMPROVED;

　　(6) The bypass/energy-saving conversion function is convenient for users to switch between energy-saving and bypass operation status at any time to ensure stable operation.
