Great summer, residential, hotels, high-rise buildings, schools, water constant pressure water supply cabinet 

 System function 

 WS series of constant pressure water supply control system uses a frequency conversion technology and advanced intelligent control logic supply, the process of change in the water pipe network pressure remain constant, and can maximize saving water and electricity. 

 WS series of constant pressure water supply control system is the adoption of global top 500 enterprises Emerson pump special frequency converter. This drive is a very mature product, the system is simple and reliable, not very complex in the middle of the connection, cable greatly reduced, all of the water control procedures and frequency control procedures all completed by the high-speed DSP, the inverter speed control process is completely water supply pressure in accordance with the feedback automatically, to an unprecedented coordination and harmonization, stability, system reliability through rigorous testing and inspection after numerous applications. 

 The system can automatically adjust the pump speed and the number of operating units, the pressure of the water supply network to maintain the required set pressure and flow, so as to improve water quality and energy efficient purposes. 

 The system can replace the high water tanks, water towers and other facilities, and valve control and other measures to improve water supply automation and quality of drinking water to prevent secondary pollution, is an ideal modern water supply facilities. 

 Features 

 1. Energy efficient 

 Set pressure on demand, according to changes in water consumption to adjust the pump speed and pump motor to run the number of units, the equipment transformer or variable flow with variable flow constant pressure water supply, so energy-efficient operation of equipment in the best condition to achieve real energy purposes. 

 2. Water pressure is stable 

 To achieve closed-loop control system can automatically adjust the set pressure and the pressure difference between the feedback system, so that pressure is kept constant. 

 3. Operation stability 

 Set pressure directly from the keyboard to set the drive, the operation is extremely simple. 

 4. Pump cycle starts 

 Each pump cycle starts, the pump will not be long without the frequent use of rust or wear. 

 5. Improve the protection 

 Short circuit, over current, over voltage, overheating, overload and other protection, pump operation, if any fault, automatically stop working and the alarm output; system with self, fault diagnosis, fault memory, fault display, automatic start standby pump etc. . 

 6. Small flow sleep function 

 Small pump can be connected with the subsidiary to make the system run at night or other low flow conditions, the automatic turn off the main pump, open the sub small pump to avoid opening the waste caused by high-power pumps. 

 7. With manual switch control, can guarantee the continuous operation of security equipment. 

 8. And the computer through the serial port can be connected, controlled by computer network diameter. 

 9. The only drive with a real-time clock in different time periods can run different pressures, timing start, stop, the maximum water saving. 

 10. Pool of low water level alarm stop, start automatically when the water level recovery, the pool of high water level alarm 

 Scope 

 1. Urban and rural residents living area, high-rise buildings, hotels, schools, hotels, restaurants and larger building domestic water supply and fire
