Frequency constant pressure water supply control panel


Summarize:

ZHB series frequency constant pressure water supply control cabinet is the development of a new generation of energy-saving water supply products. Its core is the exchange frequency conversion technology and the microcomputer control technology. Use closed-loop control system. The control panel can automatically adjust the pump speed and the number of units running, so that the pressure of the water supply network to maintain the required pressure and flow, so as to improve the quality of water supply and energy efficient purposes. The control cabinet can replace the high water-level tank, water tower and other facilities and valve adjustment and other measures to improve the degree of water supply and drinking water quality, to prevent secondary pollution, is an ideal modern water supply products.


Model description:

ZHB-G/S―□―□


Main specifications:

Environment temperature: -10℃~50℃

Control way: exit constant

pressure regulating precision: <±0.01MPa

Altitude: less than 1km

Power: Three phase four line 380V±10%

Vibrates: <0.5G


Application:

Living area, high-rise buildings water supply, hotels, restaurants and large-sized structures' water supply and fire fighting water; district heating water supply system and air condition's hot water circulation system; water pumping stations, pipeline system; industrial production and water recycling water of industrial boiler water supply system; sewage treatment system; old water supply (pressure water tower high water-level water supply) transformation; agricultural irrigation, sprinkler irrigation and music fountain.


Product Features:

3 sets of the main pumps + 1 small pump, a variety of control modes optional;

Control mode selectable;

Flexible addition and subtraction pump control logic;

Flexible sleep pump control function;

Regular rotation control, can effectively prevent the rust of the pump;

Up to 8 periods of pressure control, and each period

Can be set to any arbitrary pressure control and timer switch function;

Pipe network pressure monitoring, alarm; pump grounding, lack of and so on perfect protection.


Advanced technology:

the use of computer control to control the cabinet according to the pressure to achieve intelligent constant pressure variable supply water supply;


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 running in the best state of energy efficient;


Water supply pressure is steady:

The system achievea closed-loop control, can automatically adjusts the pressure set and system pressure difference, the pressure to maintain a constant;


Operation is stable:

The system is controlled automatically by the inverter or inverter intelligent controller, the operation is extremely simple;


Extended motor pump life:

The pumps are soft start, eliminating the impact of the starting current. The pump loop start, so that the standby pump will not rust or wear in a long time.


Perfect protection function:

With short circuit over-current over-voltage overload protections and others, pump operation such as failure, pump will stop working and alarm output automatically; the system has a self-test fault memory fault display automatically to start standby pump and other functions;


Small flow sleep function:

Can be connected with a small pump attached to the system running at night or other small flow conditions, automatically shut down the main pump, open the subsidiary pump, for avoiding the waste caused by high-power pump.


Operation function:

The frequency changer and the controller programming and the establishment are convenient and simple, easy to grasp;


Hand automatic switching function:

with manual switch control, you can ensure the safety of continuous operation of equipment;


Constant pressure water supply principle:

When water supply automatic control system works, the equipment constantly transfers transmission signal to the high sensitivity pressure transducer which is installed in the water supply network and detect the water supply network's pressure change when water-level changes, after the computer to determine and compare with the setting pressure, to issue the command to the controller, the controller pump,motor’s speed and enable units by changing frequency, automatically adjust the peak water consumption to ensure that the water supply network pressure constant to meet the user’s needs of water.


Ordering Information:

Frequency constant pressure water supply control cabinet specifications are numerous, all aspects of high technical requirements. Please be sure before order.
