Changji box no negative pressure water equipment Walter Water Equipment Co., secondary water supply equipment solutions expert! Box no negative pressure water equipment principle: constant frequency of equipment put into use, the water pipe network of water into the water tank, the tank to exclude air from the vacuum to eliminate, to be filled with water, remove the vacuum automatically turns off. When the water pipe network pressure to meet the requirements of the water, the system consists of a bypass valve from the users directly to the water pipe network; when the water pressure in the pipe can not meet the water demand, the system pressure signal from the remote pressure gauge back to the inverter controller pump operation, and automatically adjust the speed according to the size of water pressure water supply, if the running speed of the pump reaches the power frequency, start another pump frequency operation. Pump water, if the water pipe network is greater than the pump flow, maintain normal water supply system; water peak, if the water pipe network is less than the pump flow, water tank water as a supplemental source of water supply is still normal at this time, vacuum to eliminate air from entering the water tank, the tank vacuum destruction, to ensure that the water pipe network does not produce negative pressure, the water peak, the system has returned to normal supply state. When the water pipe network without water, resulting in declining water tank level, level detector will signal back to the inverter controller, the pump automatically shut down to protect the water pump, water tank can store and release energy, to avoid frequent pump starts. Box no negative pressure water equipment Features: 1. Constant equipment less investment, no pool, no disinfection. 2. Constant devices are small, small footprint, easy installation. 3. Energy efficient, fully used water pipe network pressure, forcing triple laminated, low power consumption, low running costs. 4. All stainless steel runner, sealed with pressure steady flow compensation system, completely isolated from sources of pollution, clean and green. 5. The constant pressure device stable and will not cause pressure fluctuations municipal pipe network. 6. The automatic control operation, unattended design. 7. superior protection, automatic fault display, alarm. 8. Analog screen human-machine dialogue can always check, set and adjust operating parameters. 9. bypass design, automatic switch, power off the water. 10. High life. Life constant frequency of high equipment operating efficiency can be increased more than three times the life of the pump. Box overlying water supply equipment advantages: 1, municipal water supply pipe network does not affect the box overlying water supply equipment directly connected to the water pipe line, through the pressure sensor tube pressure feedback to the inverter, the inverter according to the setting good pressure values ??of the ideal value and safety equipment and frequency control start and stop the pump unit, the use of non-negative frequency of water supply equipment does not impact on the surrounding users. 2, saving water tanks overlying water supply equipment for all type seal structure, the complete elimination of the pipe run, run, drip, drain phenomenon; no pool equipment, water tanks, saving cleaning the pool, the water tank. 3, energy saving box overlying water supply equipment is in series with the municipal pipes, you can take advantage of municipal water pressure and improve the water pump can only add pressure difference, power equipment, low operating costs. 4, saving investment Box overlying water supply equipment can take advantage of the pipeline pressure, pump selection is small, saving equipment investment; do not need to set up the pool, water tank, can reduce the corresponding costs; equipment operation and no secondary pollution, no water investment. 5, control instruments and line no damage; 6, after the transmission frequency counter, non-first-mover drive parameters; 7, open the pump discharge valve, excluding gas; 8, the system first starts or maintenance, repairs, starter should open the inlet valve, close the outlet valve; check whether the system has spilled around the drain. If diarrhea should be started after the leak excluded; box overlying water supply equipment operating environment: 1, ambient temperature: 5 ~ 50 ℃; Relative humidity: ≤90%, non-condensing. 2, non-corrosive significant ambient air pollution gases, water vapor, dust and so on. 3, Box overlying water supply equipment installation places the maximum altitude of 1000m. Agents basic conditions: 1. highly recognized Walter company's development philosophy, willing to work with us to create great cause together. 2. love to drainage, water supply industry sales career, have a good working attitude. 3. There is a good social relationship or have their own marketing team, with good development potential market credibility 4. good operating conditions stable company priority. 5. voluntarily accept and comply with the company, "agency agreement" by the provisions. 6. With rich resources given priority.
