Frequency control cabinet features

[Abstract]:
Compared with traditionally-controlled motors, inverter-controlled motors have the most practical significance in terms of energy conservation.
1, save energy
 
Compared with traditionally-controlled motors, inverter-controlled motors have the most practical significance in terms of energy conservation. The motor operating conditions that are supplied according to water injection and fuel delivery requirements are economical operations, which can save 48.8% of electricity.
 
2. Lower operating costs
 
The operating cost of traditional motors consists of three components: initial procurement costs, maintenance costs, and energy costs. Among them, energy costs account for approximately 77% of motor operating costs. Through the reduction of energy costs by 44.3%, coupled with the reduction of impact on the equipment after the frequency conversion start, maintenance and repair volumes also follow, resulting in greatly reduced operating costs.
 
3, improve the accuracy of pressure control
 
Variable frequency control system has precise pressure control capability. Match the pressure output of the motor with the amount of water required by the system. The output of the variable frequency control motor changes as the motor speed changes. Due to the increased precision of the frequency conversion control motor speed, it can maintain the system pressure change of the pipe network in the range of 3pisg, which is within the range of 0.2bar, effectively improving the quality of working conditions.
 
4, extend the service life of the motor
 
The inverter starts the motor from 0Hz, and its start acceleration time can be adjusted, thereby reducing the impact on the electrical and mechanical parts of the motor at the start, enhancing the reliability of the system and prolonging the service life of the motor. In addition, the frequency conversion control can reduce the current fluctuation when the unit starts. This fluctuating current will affect the power supply of the power grid and other equipment. The inverter can effectively reduce the peak value of the starting current to the minimum.
 
5, reduce the noise of the motor
 
According to the operating conditions of the motor, after installing the variable frequency speed regulation, the motor operation speed is obviously slowed down, so the noise during operation of the motor is effectively reduced.
