Life of constant pressure frequency conversion water supply equipment 
 Product Overview: 
 Relaxation Springs series of automatic intelligent sets of water supply equipment is a new no-tower water supply equipment, efficient, stable and easy to maintain, it mainly consists of the pump unit, the booster regulator device and control device composed of three parts. Pump unit to determine the water supply capacity of the equipment; play an accumulator regulator booster regulator device to cope with a small amount of water and normal pipeline leakage, reduce the pump start and stop times to achieve the purpose to extend the life of the equipment, booster regulator device achieving an indispensable part of automated water supply; stable operation of the control system coordination system; when water consumption increases, the pipe network pressure drop, the pump automatically starts the water supply. 
 Automatic water supply equipment according to the different ways of automatic functions can be divided into the atmospheric pressure automatic water supply equipment and Constant Pressure Water Supply Equipment, characteristics vary widely in the domestic water supply, building fire, production, water supply and spray kinds of field. 
 The pump is water supply equipment, water supply equipment to achieve the guarantee of its basic functions. Matching pumps for water supply equipment according to relevant national standards, can be a different flow, head of the pumps. In accordance with the different water needs, the product can be 1 to 4 or more pumps operating in parallel, can also be a pump unit with a separate set of booster regulator (flow) pump as main pump switch in the small flow range run in order to improve efficiency, to further save energy and reduce water supply costs. 
 The constant pressure frequency conversion water supply equipment of life (fire) is a frequency conversion technology, programmable control technology in a new generation of mechatronic automatic water supply equipment. 
 The equipment consists of imported AC inverter, industrial-grade programmable logic controller, digital PID regulator, imports of low-voltage electrical appliances, pressure sensors, liquid level controller and pump and other closed loop to adjust the frequency control water supply system. The system can change according to the instantaneous pressure of the pipe network, and automatically adjust the speed of a pump motor and multiple pump motor starting and stopping, to meet the requirement of constant pressure variable water supply or transformer variable water supply, so that the pressure of the end of the water supply network remains constant, making the entire water supply system to always maintain the best condition of the energy efficient. 
 Application of this equipment in the water supply system can be removed from the traditional water supply facilities, water towers, high water tanks and other facilities (equipment), and significant energy saving effect is a key state to promote the application of new technology energy-saving products. 
 Product Features: 
 1, compact structure, small size, small footprint, without the construction of high water tank or water tower, investment, quick to install, easy centralized management; 
 2, imported frequency converter and related components, reasonable design, simple operation, reliable performance, and fully automatic operation; 
 3, with a variety of fault display and available for inspection records undervoltage, overvoltage, overload, short circuit, phase loss, water dry automatic protection shutdown protection function, safe to use, easy to maintain; 
 Free to set the pressure of the pipe network, according to the actual amount of water to adjust the pump speed, so that it is always in the efficient functioning of the state; of multiple low-power pump pumps instead of high-power pump better suited to traffic dramatic changes, to avoid "in Malaysia car pull "phenomenon, the energy saving effect is more significant. Compared with the constant speed pump water, eliminating the overpressure and the return of reactive power losses, energy-saving rate of 20 to 50 percent; 
 5 by the inverter or soft starter pumps soft start soft stop, so that the power grid and pipe network from the impact. The water hammer phenomenon and greatly reduce equipment operating noise and extend the life of the related equipment; 
 6, more than one pump a variety of cyclic operation mode, the pump run time, to avoid a water pump is idle and rust; 
 7, the water supply directly to the user, the secondary pollution of water; 
 8, the variety specification is complete and can be any supporting a wide range of applications; 
 9, the control program, according to user need to implement a variety of control methods. Timer switch system, fire linkage, low flow and zero flow, for example: automatic shutdown sleep, centralized management of the host computer; 
 Atmospheric water supply of 10, the pipe network can be avoided exposed piping Donglie; may need to be adjusted to the equipment supply pressure to meet the water pressure of the water peak of building top-level requirements. 
 Main purposes: 
 A high-rise urban residential area, enterprises and other domestic water. 
 2, various types of industrial water (such as cooling water circulation requires constant pressure water supply of water for production). 
 3, all kinds of water plants, sewage treatment plants, airports, agricultural irrigation and drainage stations and sprinkler station. 
 4, environmental protection, water treatment, penetration analysis systems, production lines processing systems, industrial plant cleaning. 
 5, oil pipelines, oil depots, oil port of constant pressure oil system. 
 6, renovation of water supply system (pressure tanks, water towers, high water tank). 
 7, industrial boilers regulated supply system, hot water supply system. 
 8, a variety of fire-fighting facilities. 

 Working conditions: 
 Pressure tank working pressure: 0.6MPa, 1.0MPa, 1.6MPa. 2, the pressure tank fire storage volume greater than: 150L, ??300L, 450L. 3, the regulator of the pressure tank water volume greater than 50L. 4, pressure tank buffer the volume of water differential pressure of 0.02 ~ 0.03MPa regulated water volume differential pressure of 0.05 ~ 0.06MPa. 5, pressure ratio: ab value of 0.6 ~ 40 ℃.
