Brief Introduction

 

High frequency drive is mainly used to adjust the working frequency of the equipment, reduce energy loss, and can start the equipment smoothly, reduce the damage to the motor when the equipment is started directly with high current. At the same time with analog input (speed control or feedback signals), PID control, pump switching control (for constant pressure), communication functions, macro functions (for different occasions with different parameter settings), multi-section speed and so on. High frequency drive can be widely used in industrial and agricultural production and all kinds of buildings for water supply, drainage, fire fighter, sprinkler network pressurization and HVAC hot and cold water circulation and other occasions of automatic control.

 

For high frequency drive controlled motors and traditional motors, energy savings is the most obvious advantage. In accordance with the water injection and oil demand of the motor, it can save 48.8% of the power.

 

The operating cost of a conventional motor consists of three items: initial purchase cost, maintenance cost and energy cost. Energy costs account for approximately 77% of motor costs. Through the energy cost reduction of 44.3%, coupled with the frequency conversion after the start of the impact on the equipment to reduce the maintenance and repair also followed by a reduction in the amount of running costs will be greatly reduced.

 

The high frequency drive has precise pressure control capability. Match the pressure output of the motor with the amount of water injection required by the system. The output of high frequency drive motor changes with the change of motor speed. Because of the increased precision of the frequency conversion control motor speed, it can keep the system pressure change of the pipeline network within the range of 3pisg change, that is, within the range of 0.2bar, which effectively improves the quality of the working condition.

 

The high frequency drive starts the motor from 0HZ, and its starting acceleration time can be adjusted so as to reduce the impact on the electrical and mechanical parts of the motor during starting, enhance the reliability of the system, and extend the service life of the motor. In addition, high frequency drive can reduce the current fluctuation when the unit starts, this fluctuation current will affect the power grid and other equipment power, high frequency drive can effectively reduce the peak of the starting current to a minimum.

According to the requirements of the working conditions of the motor, after the installation of high frequency drive, the motor running speed is obviously slowed down, so it effectively reduces the noise of the motor when running.
