Outlet pressure of the water supply network is determined according to user needs. The traditional way is to use constant pressure water towers, high-water tank, pressure tank and other facilities to achieve. In recent years, with the frequency control technology matures, its remarkable energy efficiency and reliable and stable control, has been widely used in water supply systems. Box no negative pressure water equipment system for the implementation of variable speed pump motor, based on water consumption and water pressure change is detected by the computer, computing, automatically change the pump speed to maintain a constant pressure in order to meet the water requirements, is the most advanced and reasonable saving water supply system. Compared with the traditional towers, water tanks, pressure tanks and other water supply, whether it is investment, stability of operation of the economy, or the system, reliability, automation and other areas have advantages: (1) energy efficient. Compared with the traditional way of water supply box no negative pressure water equipment can save 30% -60%. (2) small footprint, less investment, high efficiency. (3) flexible configuration, high degree of automation, functional, flexible and reliable. (4) a reasonable run, due to the decline in the average speed of the day, the average torque shaft and wear reduction, pump life will be greatly improved. (5) Since the pump can achieve soft start and soft stop, and eliminate water hammer effect (water hammer effect: direct start-up and shutdown, the kinetic energy of the liquid is suddenly increased, resulting in a great impact on the network, there is a great destructive). (6) easy to operate, saving time and effort. Box no negative pressure water equipment principle box no negative pressure water supply equipment to the pipe network (or user of water flow) to set parameters to automatically adjust the pump motor speed by computer control the output frequency to achieve the pipe network closed-loop pressure regulator (PID), the water supply system automatic constant steady pressure to the set value: that the water increases, the frequency increases, the pump speed to accelerate, the amount of water corresponding increase; when the water was reduced, the frequency decreases, slowing pump speed, water quantity is reduced accordingly, thus ensuring efficient users of water pressure and water requirements, while achieving improved water quality and water efficiency purposes, "how much water, how much water is available"; adoption The device does not need to build high water tank, water towers, water quality and no secondary pollution, is an ideal modern construction of water supply facilities. Box no negative pressure water equipment range of applications related to industry: Design Institute, which, fire stations, property companies, fire and other professional construction unit residential quarters, office buildings, hotels, restaurants, shopping malls, supermarkets, subways, stadiums and so on.
