Product features
1, the use of programmable controller, flexible program, high accuracy, strong reliability, many functions, fast response.Direct control of variable frequency governor.Follow the change of water consumption according to the set pressure, adjust the speed of the pump motor and the number of pumps at any time, make the equipment run on the set parameters, achieve the purpose of energy saving.
2. Large units are equipped with pressure stabilizing pump or pressure stabilizing tank. When the water consumption is small to a certain value, the main pump can stop running to reduce the mechanical wear of the pump motor and save energy.
3, the water pump are soft start, prolong the life of equipment, eliminate the impact of starting current on the power grid.
4, according to the change of water consumption, the pump cycle frequency conversion operation, first start first stop, so that the pump balance work.When one pump is running for six or twenty-four hours, it automatically switches over to another.
5. This equipment is characterized by double constant pressure control, and it can be used in the same set of equipment for living and fire fighting, saving investment for users.And one machine dual use, greatly improve the use efficiency.
6. The equipment has the advantages of compact structure, small occupation area, quick installation, low investment, stable operation and no pollution.
Energy-saving principle
There are two ways of constant speed and variable speed in the operation of water supply pumps, which can adjust the flow according to the requirements of water supply users.When running at constant speed, throttle regulation is generally adopted, which has the disadvantage of low efficiency and large energy consumption.During variable speed operation, the pump speed can be changed during operation to adjust the output flow rate to adapt to the change of water consumption, and ensure the constant pressure of pipe network, and the pump always works under the condition of high efficiency.When water consumption is reduced, the pump runs at a lower speed.Because the pump shaft power is proportional to the third power of the speed.When the speed drops, the shaft power drops greatly, so the variable speed adjustment flow rate is the most economical and reasonable in improving mechanical efficiency and reducing energy consumption.
