Pump frequency changer, also known as the pump frequency conversion controller, the traditional booster method is the water tower, high water tank or pressure tank booster equipment, its equipment investment cost is high, and must be higher than the actual water pump height Pressure to increase the amount of water, the results tend to increase the pump shaft power and energy loss, but also easily lead to secondary water pollution. With the pump inverter, better control of water pressure, and now to say that the pump inverter works and wiring methods. Pump inverter schematic Pump inverter working principle Pump inverter automatic control system work, the device installed in the water supply pipe network through the high sensitivity of pressure sensors to detect changes in the water supply pipe network pressure changes, and constantly transmit to the inverter Change the signal through the microcomputer to determine the operation and set the pressure comparison, the controller issued a command to change the frequency, the controller by changing the frequency to change the pump motor speed and the number of units enabled to automatically adjust the peak water consumption to ensure water supply Pipeline pressure constant, to meet the needs of users of water.
Every great bicycle starts with a solid platform: the frame. Our frame is designed to be strong and sturdy. Ever since the very beginning, we understand the importance of frame, and we know what it means to a bicycle, so we spent years of time and put great effort in it, now we can proudly say that we are able to design and make any frame that our customer request.
