Walter pipe network overlying water supply equipment Equipment Co. Merchants national agency, secondary water supply equipment sailing toward the beautiful areas of the pipe network overlying water supply equipment is a new energy-efficient water supply equipment. Department of overlying water supply pipe network equipment using the most advanced microcomputer control technology, the combination of the inverter and the motor pump mechatronic high-tech energy supply unit. Pipe network overlying water supply equipment to pump water end users of water pressure or flow) to set the parameters by computer control of the inverter output frequency and thus adjust the pump motor speed, closed-loop pipe network users to adjust the water pressure, water supply The system automatically constant steady pressure to the set value: the amount of water increases, the frequency increases, the pump speed to speed up; when the water was reduced, the frequency decreases, the pump speed slows down. This ensures that the entire network users always have enough water pressure (the pressure is consistent with the user-defined) and water (with the use of water changes the user changes) pipe network overlying water supply equipment is an original water pipe network Based on the pressure again pressurized water supply equipment. According to the "water supply equipment Promotion Center," the information on it can only broke the previous non-pressure water pressurized misunderstanding, and fluid flow through the state's control to ensure that the equipment limit supercharger. Does not generate pressure on the pipe network. Users install the front pipe network overlying water supply equipment, solve the water pressure in the pipe due to the user's problem is not restricted to meet the needs of users distal high terrain. First, the effect of the water supply pipe network system in the Water Distribution Network is an important component of some of the city water supply system, responsible for delivery to the user, distribution of water mission, to the satisfaction of users of water and water pressure requirements. Because surface water distribution network to distribute a wide interval length, high demand for raw materials, equipment tubewell water tower construction steps and thus a higher share of its water supply system funded share of the total contribution of 60% -80%, in the absence of The total contribution of the water tower equipment has insignificant effect. In the water distribution process needs to spend a lot of energy, energy supply companies, 90% for primary and secondary hydraulic pumping station promotion, which accounts for some 30 percent of water consumption cost of - 40%. Together, the operating condition of the water distribution network directly affects the water pressure and water, affecting the quality of service. Thus, the distribution pipe network occupies an important position in the water supply system. Second, the placement method pipe placed pipe network with echoes township master plan, which is very close contact. In describing to the water supply network, should fit the following criteria: the need to pipe the water spread throughout the region, in quantity, water quality and water than the terms of the user's needs can be satisfied, guarantee safe and reliable water supply; pipeline attack when individual problems scale without water should be minimized; for Rural pipeline construction program should be in place, leaving room for the pipe network to carry out stage; resettlement frequency without tower water supply networks should try to make the shortest line to reach the same intentions. Selection of pipe to be appropriate to the construction simplicity, low cost as a criterion. Overlying water supply pipe network equipment manufacturers (1), water protection, when the tank water level drops below the set level, the system automatically shut down to protect. Level controller performance stable and reliable. (2), automatic reset function, power recovery after power outage or water recovery system starts automatically. (3) failure shielding pump failure pump operating procedures after exit shielded by the standby pump takes over.
