Pressure water supply equipment is to water distribution systems in an automatic adjustment device, both to ensure that the required pressure in the water supply system, there are certain to adjust the volume, it has a similar function with towers or high water tank, and it is also known as the water tower pressure tank. Pressure water supply equipment utilizing the compressibility of air, water pump in the direct water supply system, set up a pressure tank and pump connected to the water supply network. When the water is less than pump out the water, the tank water level rises, which compressed air pressure rises when the pressure reaches limit pressure controller automatically cut off the power supply, water pumps stop working. At this point the air pressure in the tank to continue to pressure the tank into the water supply network. With the tank water level falling, the pressure drop reaches the lower limit of the pressure controller automatically when the power is turned back pumps, pressure tank and pipe network for water supply, and so forth until the cycle of uninterrupted water supply pipe network requirements. When the pump stops working, fill the tank in the water level drops, the outside air through the suction valve into the tank qi, to be pressed into the pressure tank when the pump starts, to automatically qi purposes. Water supply equipment, water supply equipment principle works: works of water supply equipment constant pressure water supply equipment principle is to automatically adjust the number of pump units and run a water pump speed changes according to the user, so that the pump outlet pressure remains constant. Water supply equipment, water supply equipment principle when a user less than a water pump out the water, the control system according to changes in water has a water pump to adjust the operating frequency, when the water increases the pressure drop in the pipe system, when the pressure sensor to detect to signal to the computer control unit, run by computer to determine, issue commands to the inverter to control the pump motor, the speed is accelerated to ensure that the system pressure constant, whereas when the water was reduced to slow down the pump speed to maintain a constant pressure . When the water is greater than a water pump, the first pump is switched to frequency operation, the second pump start frequency adjustment operation, when the water is greater than two pumps out water, it will automatically stop one or two sets of pump operation . Throughout the operation, the water supply equipment supply equipment principle remains constant pressure system, the pump is always working in the high zone, both to ensure constant water supply equipment principle user, but also saves energy. How much water users is constantly changing, so the water supply shortage or excess supply situation have occurred. The imbalance between the supply of water and concentrated reflection on the water pressure, water that is more and less water, the pressure is low; less water and more water, the pressure. Maintain a constant water pressure, can maintain a balance between water supply and water, too much water that the water for a long time, the water supply came from less, thereby improving the quality of water supply.

Water supply equipment principle Product Overview Over the years, the town municipal water supply pipe network pressure to meet the ordinary low-rise buildings are set in their water supply water pressure, so that the majority of buildings are urban secondary pressurized water supply must meet the building The water demand. China's urban secondary pressurized water supply has gone from "reservoir + booster pump + water tower water supply", "reservoir + + high pressure pump tank water supply", "reservoir + booster pump + pressure Tank water supply "and" cisterns or storage tanks + pressurized water supply equipment principle water supply unit "four stages of development, has entered the" no negative pressure water pipe network overlying water supply pressurized crew "New Era . Currently, in the field of domestic secondary water towns, in addition to the "reservoir + booster pump + water tower water supply" to basically disappeared, the other three second pressurized water supply have to use, but with "reservoir or storage tank + pressurized water supply equipment principle water supply unit, "which, while no negative pressure water pipe network layers ways is just beginning, is gradually replacing other water ways and become urban secondary pressurized water system mainstream. In addition to "negative pressure water pipe network layers mode", the other four water supply have a common feature, that is, the second pressurized water supply system have cisterns or storage tanks. For ease of description, the content will be collectively referred to herein below its reservoir water supply. In this type of water supply, at work and the first municipal water pipe network pressurized vent into the pool, and then pressurized by pumping pressurized equipment into the water supply network from the pool. Although the above water supply to meet the demand of water pressure, but there are sources of secondary pollution and energy waste problem difficult to solve. With the development of society, energy supply has become tighter, build energy-saving society are growing; on the other hand, continued to improve living standards for drinking water quality requirements is also rising; in addition, water shortages have been a threat to urban residents The problem of drinking water, water prices continue to increase; urban construction land with growing tension rising land prices. Because of these reasons and their own lack of existing water supply, water supply problems in the current increasingly prominent, has been unable to meet the needs of social life. Community energy, water, health, safety, pollution-free new water supply demands more urgent. In this context, negative pressure water pipe network layers came into being.
