4)Up to 8 periods of pressure control, and each period
5)Can be set to any arbitrary pressure setting control and realize time switch function;
6)Pipe network pressure monitoring, alarm; pump grounding, loss phase and so on perfect protection.
6.Structural features
1)Advanced technology: use of computer control to control the cabinet according to the pressure to achieve intelligent constant pressure variable water supply;
2)Energy efficient: the system can set pressure on demand, the system automatically adjusts the pump speed according to the set pressure and the number of pumps running, so that the equipment are running in the best state of energy efficient;
3)Stable water supply pressure : the system to achieve closed-loop control, can automatically adjust the difference between the set pressure and system pressure , maintain the pressure constant.
4)Stable Operation :
The system is controlled automatically by the inverter and inverter intelligent controller, the operation is extremely simple; extend the life time of motor pump. Each pump is soft starter . eliminating the impact of the starting current. Each pump cycle start, so that the standby pump will not rust or wear for using a long time
5)Perfect protection function:
Have short circuit ,over-current, over-voltage ,overload protection and other protection function, pump will stop working and alarm output automatically if the pump run failure; The system has a self-test fault ,diagnosis fault, memory display fault automatically start standby pump and other functions.
6)Small flow sleep function:
Can be connected with a small pump attached . the cabinet can shutdown the main pumps if the system is running in the night or other small flow conditions . start the subsidiary pump, to avoid the waster caused by big power pumps.
7)Operation function: The frequency inverter and the controller programming and parameter setting are convenient and simple, easy understanding .
8)Manual automatic switching function: have manual switch control, you can ensure the safety and continuous operation of equipment.
7.Constant pressure water supply principle:
When water supply automatic control system is working , through the high sensitivity pressure transducer which is installed in the water supply network. The equipment detect the water supply network's pressure change when water level changes.
Continuously transmission the frequency inverter's change signal. After judging by microcomputer and comparing the setting pressure, send one changing frequency command to the controller. The controller change the pump motor speed and the number of running by changing the frequency automatically adjust the peak water consumption to ensure the water supply network pressure constant and meet the needs of users 'water.
