What are the benefits of submersible pump frequency conversion control?

Deep well submersible pump is a fountain, drinking water conveying, senior irrigation, hot springs, transportation facilities, etc., deep well submersible pump excellent performance and is widely applied in various fields. Submersible pump according to the working condition of selection, some work conditions of a submersible electric pump to complete the 80 – meter – high water and 40 meters water supply facilities, how under the limited conditions can meet the two conditions at the same time? Under this pricing with frequency conversion control system.

Many deep well pump, selection of deep well submersible pump without constant pressure control, but the water pump water directly, when water load reduction (user) less water, pipe network pressure will rise, often cause the place such as blowout, valve and joint to cost a lot of water, also increase the maintenance cost, in particular, many rural USES is reinforced plastic pipe, may be more likely to cause detonation tube.

Way of constant pressure water supply has a water tower water supply and air pressure and variable frequency constant pressure water supply three ways of water supply, variable frequency constant pressure water supply control mode is the least investment, is also the most energy saving control mode, no covering problem and pressure of water supply for the water tower water supply pump is frequent start-stop problems, practical inspection, variable frequency constant pressure water supply control mode is the best way of constant pressure control. To save energy, reduce the cost of water supply.

Can let the deep well pump and frequency control in the water, reduce the speed of water pump, and decreases in the consumption of electricity of deep well pump is square torque load, the power and speed of the direct ratio three times, when the droop is 60% of the rated speed, the power is 21.6% of the rated, can save 78% of its electricity, in addition, using frequency control of motor speed, can improve the power factor, the active power, reactive power into practice has proved that controlled by frequency conversion power saving rate is at least 30% increase the service life of pump.

Second, the inverter has a strong protection function, the water pump overload, over-current, stall, under voltage, over voltage and other causes of damage of the pump in a timely manner to protect, not cause the pump to burn out.

Inverter make pump soft start when starting, the pump from 0 speed according to the acceleration time and slowly increase the speed, in this way, to reduce the impact of the large current when starting the pumps, also reduced the pump on the extremely rapid startup wear between.

Pump stop inverter to pump according to deceleration time, gradually stop, in this way, reduced because of a sudden stop, water entrapped in the network to form water hammer, the water pump caused great damage.

Practice has proved that using frequency constant pressure control can increase the service life of the pump more than double, also can effectively reduce the number of maintenance of the pump.

Three, intelligent control automatic operation:

The PID closed-loop regulating water supply equipment, constant pressure of high precision, small water pressure fluctuations. With overload, short circuit, over-current and automatic protection function, equipment operation is stable, reliable and easy to use and maintain. Stop water pump, timing function such as automatic water pump operation, can realize no one duty. Remote monitoring system can be built, and real-time monitor the running status of equipment.
