Automatic negative pressure water equipment Overview: automatic negative pressure water equipment is the AC frequency control technology and computer control technology being applied to the pump automatic control equipment, and combined with the water pump unit mechatronic devices. Its core equipment AC variable frequency control cabinet combines advanced computer control frequency conversion technology, advanced computer control technology and advanced PID control microcomputer programmable controllers and other current international advanced technology. Automatic negative pressure water supply pipe network equipment based on the instantaneous change in pressure and flow parameters, automatically change the number of units and run the pump speed to achieve constant pressure variable water supply loop regulation, so as to improve the company's quality and efficient energy-saving purposes. Automatic negative pressure water equipment works: no basic working principle of automatic negative pressure water equipment are adjusted automatically run the pump station number and a water pump speed changes according to the user, so that the pump outlet pressure remains constant. When a user less than a water pump out the water, the system according to changes in water has a variable speed pump is running, when the water increases the pressure drop in the pipe system, when the pressure sensor to detect the signal transmitted 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, so that the pump speed slows down to maintain constant pressure. When the water is greater than a water pump, the first pump is switched to frequency operation, the second pump start frequency control operation, when the water is less than two pumps out water, can automatically stop one or two pumps run. Throughout the operation, and always maintain the same constant pressure system, the pump is always working in the university area, both to ensure constant water supply users, but also saves energy. Equipped with full equipment without operator. Automatic negative pressure water equipment features: 1, no need to build the pool, energy, capital: HBW-automatic negative pressure water equipment economic health, energy-saving effect is remarkable, proved: using intelligent non-negative steady flow of water supply equipment saving more than 50% of the new pool costs, compared with other water supply equipment, can save 20% to 40%. 2, easy installation, saving floor space: HBW-automatic negative pressure water equipment can configure the horizontal steady flow can also configure the vertical steady flow tank. Both steady flow tank has different characteristics: horizontal steady flow can occupy a small space: vertical steady flow can occupy a small area, steady flow tank manufacturing and testing are in line with the provisions of GB150 "steel pressure vessel", the inner wall of the tank using an advanced "841 epoxy polyamide food container wall paint", corrosion, in line with national standards of food hygiene safety. 3, versatile and adaptable: HBW-automatic negative pressure water equipment can be used for domestic water supply, fire water, can be configured to any type of pump, when the device is used for fire when the fire should be equipped with dedicated pumps.
