When the water to meet the water pressure and water requirements, secondary water supply equipment through the bypass valve from the users directly to the water supply pipe network; when the pressure of the water pipe network can not meet the requirements of the water, the system pressure sensor (or pressure controller, electric contact pressure gauge) is given from the pump signal to start the pump running. When the water pump, if the water pipe network is greater than the pump flow, the system to maintain normal water supply, water peak, if the water pipe network is less than the pump flow, adjust the tank's water supply as a supplementary source of water still, at this time, by vacuum to eliminate air into the conditioning tank, eliminating the negative pressure water pipe network, water peak period, the system returns to normal state. If the water supply shortage or disruption of water supply pipe network which led to declining water level regulator tank, liquid level controller gives the pump stop signal in order to protect the water pump. At night and a small flow of water through a small expansion tank water pump to prevent frequent start. No negative pressure water equipment, key technology for the intelligent control system (inverter type) and adjust the vacuum tank to eliminate. Intelligent control system core part is the preparation and design of the Siemens programmable controller software by the senior professional and technical engineering staff are fully prepared in accordance with the operational characteristics of well pump frequency in the years water supply project on the basis of experience, the device has an intuitive interface, easy to operate reliable, stable performance, high intelligence and many other features. The key technology is the vacuum tank is adjusted to eliminate the program, the pipe network superimposed fully rely on the vacuum to eliminate the tank when the tank water is taking timely elimination of the vacuum tank, the tank so as to achieve a smooth internal and external pressure, thus not municipal pipe network resulting in negative effects, does not affect the normal municipal water pipes other users. Negative pressure water supply equipment to eliminate technical basic instructions: Frequency of secondary water supply equipment using computer technology and efficient vacuum processing technology overlying water supply as follows: The secondary water supply equipment through the vacuum compensation system and a fully enclosed structure to achieve a directly connected in series with the water pipe network, and to overcome the adverse effects on the pipe network. The secondary water supply equipment through the pipe network pressure gauges, vacuum degree and level signal vacuum suppressors and steady flow compensator steady flow detection device acquisition compensation within the real-time feedback via computer control vacuum suppressors and steady flow compensation Special equipment movement, suppression of negative pressure generated, ensure that the device does not affect the distribution network. When the municipal pipe network without water, the pump unit can still work, automatically shut down until the steady flow limit pressure compensator pressure drop to the electrical contacts are set automatically after boot runoff. When a power outage, water pump stopped working, water can enter the user network via straight lines. When an incoming call automatically turn the unit back to normal water supply. No negative pressure water supply equipment advantages description: 1. no negative pressure water equipment prices saving can be achieved saving 20% ??-40%, to achieve green electricity. 2. No negative pressure water equipment, small footprint, less investment, high efficiency. 3. No negative pressure water supply equipment prices, flexible configuration, high degree of automation, functional, flexible and reliable. 4. Because no negative pressure water equipment directly from the governor HBH constant pressure water supply, reduce the secondary pollution of the original water supply to prevent the infection source of many infectious diseases.
