Liaoyang centrifugal pump frequency control cabinet 
 Do not envy the spring flowers blooming, do not envy the summer sun radiance, do not envy the fall of the flower Yepiao Ling, do not envy the spring snow is long, throughout the year, the wonderful, all have variable frequency Shanghai spring ginger * water supply equipment to accompany the single set of equipment, sales of professional R & D quality and cheap Shanghai spring ginger Liaoyang centrifugal pump frequency conversion control cabinet per hour water supply quantity 50000M3 / H, can be used for large, supporting the transformation of small, medium and tap water; can be used for enterprise institutions, residential areas, rural production and living, office water. The water tower equipment works: no water tower equipment put into use, the water pipe network of water into the water supply tank, tank, air eliminator exclusion from the vacuum, to be filled with water, vacuum to eliminate automatically turns off. When the pressure of the water pipe network to meet the water requirements, the system users by-pass check valve water pipe network water supply; when the pressure of the water pipe network can not meet the water demand, the system pressure signal from the remote pressure gauge back to the inverter controller pump operation, and automatically adjust the speed constant pressure water supply, depending on the size of the water consumption if the operation of the pump to the power frequency speed, start another pump frequency operation. Pump water supply if the water pipe network of water is greater than the pump flow, the system to maintain a normal water supply; water peak, the water pipe network of water is less than the pump flow, the water supply tank of water as a supplemental source of water still water, this into the water supply tank by the vacuum to eliminate air tank vacuum destruction to ensure that the water pipe network does not produce negative pressure after the water peak, the system return to normal water supply. Liaoyang centrifugal pump frequency conversion control cabinet, look for the spring ginger brand.
