Automatic conversion water supply equipment maximum use of the existing municipal water pipe network pressure on municipal pipe network does not produce negative pressure, replace the old tank with a stainless steel tank or non-vacuum tank to reduce the water secondary pollution. It is a new generation of energy-saving products in the field of water supply. Hotline: 18774929287 Jingli Advisory QQ:? 2485882859 Changsha automatic conversion water supply equipment Product Overview: Changsha automatic conversion water supply equipment to take full advantage of existing water pipe network pressure, the use of frequency control technology for water pressure of the secondary elevated energy saving, new generation of water sanitation equipment, water supply equipment Changsha automatic frequency works: through steady flow conditioning tank will pump coupled to the water line, when the pressure of the water pipe network can not meet the water requirements, the system is given by the pressure sensor from the pump signal to start the pump constant pressure to run, when to water pressure is lower than the protection of water supply network set value (does not affect the surrounding users), close the inlet valve, the steady flow regulator tank water as a supplemental water peak After a period when the system pressure is greater than the value of the protection device, magnetic water valve is opened, water enters the steady flow adjustment tank, the device continues to function normally. Changsha automatic conversion water supply equipment is a new frequency of the device, in the municipal water system in series pipe network pressure insufficient, the outlet pressure detected by the sensor with the set value, calculated the need to increase the pressure value, determine the number of units in operation and the pump motor speed. JBW series of automatic conversion water supply equipment Changsha limit use of the original pressure of the municipal water pipe network, municipal pipe network does not produce negative pressure, replace the old tank with a stainless steel tank or non-vacuum tank to reduce the water secondary pollution. It is a new generation of energy-saving products in the field of water supply. Hua Xu automatic conversion water supply equipment Changsha is our professional and technical personnel in the frequency of water supply equipment developed on a direct connection with the water pipe network, and the water pipe network does not produce any negative secondary pressurized water supply equipment In the original, based on pressure, pressure difference how much make up. Make full use of water pipe network pressure water directly or indirectly, to avoid secondary pollution energy waste and water quality, he canceled the reservoir and rooftop water tanks, significant savings in infrastructure investment and shorten the construction period. Automatic conversion water supply equipment Changsha Composition 1, the working pump, commonly used single-stage or multi-stage horizontal or vertical water pump. 2, from small pumps and small pressure tank: zero flow even longer duration in a small flow, more energy is set. 3, frequency control cabinet: frequency control cabinet is a core part of the frequency control water supply equipment, generally by the press pump power supply manufacturers matching supply. 4, annex: including connecting pipes, and valves, check valves, safety valves (when there is little pressure tank), pressure gauge, pressure switch and the base and so on. General equipment assembled by the manufacturer assembled supply. Automatic conversion water supply equipment Changsha main function 1, automatic completion of more than one water pump soft-start, frequency to frequency operation, and the entire operation process is stopped. 2, according to changes in water into more than one pump start and stop. 3, LED pressure setpoint and the actual pressure value display. 4, LED frequency indicator, frequency exception indicates, the electrical fault condition display. 5, protection features: undervoltage protection, overvoltage, overload, short circuit protection, stall prevention, burning to prevent. Hua Xu Changsha automatic frequency conversion water supply equipment product performance and features: 1, high degree of automation, intelligent operation: Changsha 华旭生 water production equipment by the intelligent control of the central processor, work the pump, the standby pump operation, automatic switching process conduct, fault alarm, the user can intuitively and quickly find out the cause of the fault from the display. Using PID closed-loop regulation, high precision constant pressure, small pressure fluctuations. By setting various functions truly unattended. 2, reasonable control: Changsha automatic conversion water supply equipment using more than one pump cycle soft start control, start on the grid to reduce the direct impact and interference, the main pump starts working principle is: first open the first stop, the first stop first opportunity equal, help extend the life of the unit. 3, full-featured: Changsha automatic conversion water supply equipment overload, short circuit, overcurrent and other automatic protection function, the device is stable, reliable, easy to use and maintain. Having a water pump stops, the timing automatically switches pump operation and other functions. In terms of regular water supply system, the control unit can be set within the system timer switch control, timer switch pumps. Manual, automatic, single-step (only when there is a touch screen) three kinds of work, in order to meet the needs of different working conditions. 4, remote monitoring (optional features): Asahi Changsha, Changsha automatic conversion water supply equipment products in the full study abroad, on the basis of user needs, combined with professional and technical personnel for many years experience in automation and design of water supply equipment intelligent control system, system, water pressure, liquid level remote on-line monitoring, monitoring, through the powerful configuration software can monitor and record operating conditions of the system, real-time information feedback. Data collection for statistical and processing provides the entire network database management system, for query and analysis. And remote operation can be carried out via the Internet, monitoring, fault analysis and information sharing. 5, health energy: to replace the traditional roof tank water supply, elimination of secondary pollution. Changing the motor speed reaches the user pipe network pressure constant, the energy efficiency of up to 60%, the normal flow of water pressure can be controlled within ± 0.01Mpa by frequency control. 6, intelligent inverter controller (optional): each pump unit alone intelligent inverter controller, to maintain constant pressure in the flow under extreme change, the pump working state pipe network pressure fluctuations when switching smaller, more water quality with high energy and better (than regular water supply equipment saving more than 30%). Small footprint, easier installation, shorten the construction period. This control method is particularly suitable for power, flow changes, frequent starting place.

It is pressure formed by the position of the height to the water supply and, therefore, must build tall towers or build water storage tank in the building roof. Because of the volume of the water tower and water tank it is certain, at peak water often can not meet the water requirements. At the same time, because of its water storage capacity, forming a large load on the roof, and increases the load-bearing structure of the building occupied floor area. In addition, water storage tanks and water towers, increasing the chance of contamination of water is secondary. Pressure water supply equipment: water tank pressure water supply equipment is not set up on the roof, do not separate building cooling towers, water pump and tank equipment set up only in the basement or some spare place. Using pressure water to meet the water requirements. Pressure tank pressure water supply equipment is in place towers or high water tank, use pressure-tight pressure tank into the pressure pipe network, the advantage of flexibility, build faster, less contaminated, seismic and other beneficial; drawback is the volume and investment, pressure changes, low operating efficiency, the need to air compressor inflated. Therefore, more power-consuming, high maintenance costs.
