The frequency pump adopts AC frequency conversion speed regulation technology. The actual output power of an AC appliance is related to the power frequency: the lower the frequency, the smaller the actual output power.

Our daily water use is irregular, that is, the amount of water used is large and small. In this state, if a power frequency-controlled water pump is used, no matter how much water you consume, it must output at rated power. However, if the frequency pump is used, it is very different. When the water consumption is relatively small, the speed of the pipeline pressure relief is relatively slow. At this time, the processor will give the frequency converter a signal of the working frequency after comparing and calculating according to the feedback signal. When the inverter works at this frequency. When the water consumption changes, it will work at other frequencies through fast calculation (the frequency increases or decreases according to the water consumption, the greater the water consumption, the higher the frequency), and so on.

To sum up, whether the frequency pump can save energy depends on your actual water consumption. If you turn on the water to the maximum every time, the effect will not be obvious. If the water consumption is relatively small each time, the effect is very obvious, and the energy saving is as high as 50% or more. The working principle of the frequency converter is to reduce the frequency of the motor power supply, thereby reducing the speed of the water pump and providing a low-power working mode that meets the needs. Similarly, if the frequency of the water pump motor is forcibly handled, forcibly reducing the frequency of the water pump motor can only achieve the effect of energy saving, but cannot meet the working conditions, then what is the effect of energy saving? To give a relatively simple example: such as the inverter air conditioner in our daily life, if the temperature control of the air conditioner is lowered, electricity can be saved, but if the set temperature and gear position are lowered, it cannot meet the needs of heating, although it saves energy, but the working point is not reached, that is to say, it is possible to save energy by frequency conversion of the motor, but it is necessary to consider whether it can meet the requirements of the working point at low power.

More often, the main purpose of using variable frequency water pumps is not to save energy. The main function is constant pressure water supply, the use of variable frequency water pump to pressurize the pipeline, no matter when the pipeline outlet pressure is relatively constant.
