. . According to the basic laws of fluid mechanics, it can be known that the fan and water pump load is a typical square torque load. Its main characteristics are: the rotation speed, torque and load power have the following relationship:. That is, the torque is proportional to the square of the speed and the power is proportional to the cube of the speed. Usually, fans and pumps are selected based on their full load requirements. In actual applications, they do not work at full load most of the time, so as long as the average speed drops slightly, the load power will drop quickly, thereby achieving energy saving effects. However, when using the direct starting method of the motor, the speed cannot be adjusted because the commonly used windshields and valves are used to adjust the air volume or flow. This not only causes a waste of energy, but also causes impact on the power grid, vibration of the equipment, and water hammer due to the excessive starting current. Frequency converters are used to adjust the speed. The speed can be conveniently controlled according to actual process needs. For example: when the motor speed is % of the rated speed, the load power is the cube of the rated power (%), which is about %. This shows that the speed is reduced by 20% and the energy saving is more than 40%. At the same time, closed-loop constant voltage control can be easily realized and the energy-saving efficiency will be further improved. The use of frequency converters avoids the impact on the power grid during startup, reduces equipment failure rates, eliminates vibration and water hammer, prolongs the service life of equipment, and also reduces the capacity requirements and reactive power losses of the power grid. .
