The actual power consumption of the pump load is basically proportional to the third power of the speed. When the average flow rate required by the user is small, the fan and pump use frequency control to reduce their speed, and the energy-saving effect is very obvious. However, the traditional fan and pump use baffles and valves for flow regulation, the motor speed is basically unchanged, and the power consumption changes little. According to statistics, the electricity consumption of fans and pump motors accounts for 31% of the national electricity consumption and 50% of the industrial electricity consumption. It is very important to use variable frequency speed regulating device on this kind of load. At present, the application of more successful constant pressure water supply, various types of fans, central air conditioning and hydraulic pump frequency control.

The controller detects this contact and calculates the position of (X, V), then operates in a manner that simulates a mouse. Resistive touch screen is not afraid of dust, water and dirt, and can work in harsh environments. However, because the outer layer of the composite film is made of plastic material, the anti-knock property is poor, and the service life is affected to a certain extent. Resistive touch screen uses pressure sensing to control, its surface is a layer of plastic, the bottom is a layer of glass, can withstand the interference of harsh environmental factors, but the feel and light transmission is poor, suitable for wearing gloves and can not be directly touched by hand occasions.
