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. It can save electricity and reduce water supply cost.
Frequency conversion control can make submersible pump in water consumption, 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.
Frequency converter has strong protection function, the pump overload, over current, stall, undervoltage, overvoltage and other factors that cause pump damage timely protection, not cause the pump to burn out. The frequency converter makes the water pump start soft, that is, the water pump from 0 speed according to the acceleration time, slowly increase the speed, so as to reduce the pump when starting the big current impact, also reduce the pump when starting the rapid start of wear.
When the pump stops, the inverter makes the pump stop step by step according to the deceleration time. In this way, it reduces the water hammer formed by the water stuck in the pipe network due to sudden stop, which causes great damage to the pump. It has been proved that using frequency conversion constant voltage control can increase the service life of water pump by more than one time and effectively reduce the maintenance times of water pump.
Intelligent control automatic operation: the water supply equipment adopts PID closed-loop regulation, with high constant pressure accuracy and small fluctuation of water pressure. With overload, short circuit, over current and other automatic protection functions, the operation of the equipment is stable, reliable, convenient to use and maintenance. It has the function of water shortage stopping pump, timing automatic switch submersible pump running, etc. Remote monitoring system can be established to monitor the operation of equipment in real time.
