For example, a water pump motor with a power of 55kW, when its speed is adjusted to 8% of the original speed, its power consumption is 28kW/h, and the power saving rate is 48%. But if the speed is adjusted to the original 5%, the power consumption becomes 6 kilowatts per hour, and the power saving rate reaches 87%. 2 Adopting power factor compensation for energy saving, reactive power will not only heat the equipment and increase the wear of the wires, but the most important point is that the reduction of the power factor leads to the reduction of the active power of the power grid, thus resulting in a large amount of reactive power. It is consumed in the line, resulting in a reduction in the use efficiency of the equipment, and the waste phenomenon is very serious. After using the frequency conversion speed control equipment, the filter capacitor inside the frequency converter can further reduce the reactive power loss and obtain the active power of the grid. Increase. 3 Use the soft start method to save energy. Because the motor is started by Y/D start or direct start, the starting current is four to seven times the rated current, which will cause a serious impact on the power supply grid and electromechanical equipment. The requirements for the capacity of the power grid are also very high. A relatively large current will be generated when starting, and the damage to the valve and baffle during vibration is also very large, and it is also very detrimental to the service life of pipelines and equipment. . The use of the frequency conversion device uses the soft start function of the frequency converter to make the starting current start from zero, and the value will not exceed the rated current, so the impact on the power grid and the requirement on the power supply capacity are also greatly reduced, so that the valve And the service life of the equipment is also greatly extended.

BOD is an indicator of environmental protection. The calculation method of the biochemical oxygen demand is as follows: BOD (mg/L)=(D1-D2)/PD1: the initial dissolved oxygen of the diluted water sample (mg/L) D2: the diluted water sample is cultured in a 2℃ constant temperature incubator After 5 days, dissolved oxygen (mg/L) P=water sample volume (mL)/final volume of diluted water sample (mL) The ratio of biochemical oxygen demand to chemical oxygen demand can indicate how much organic pollutants are in the water It is difficult for microorganisms to decompose. Organic pollutants that are difficult for microorganisms to decompose are more harmful to the environment. Different from COD (Chemical Oxygen Demand, ChemicalOxygenDeman: COD, Chemical Oxygen Demand is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample.
