Problems solved by technology
[0002] In the past, the maintenance of the reinjection well was very backward. Only after the water overflowed from the reinjection well, the reinjection well was maintained. The result was too late. The improper and untimely maintenance of the reinjection well made it difficult to ensure the reinjection water. The amount reaches the original design value, and even makes recharging impossible in severe cases

Embodiment Construction
[0007] figure 1 Among them, the cumulative pumping time T1 of the pump should be much longer than the downtime of the pump, that is, the cumulative time T of stop-work-stop of the hoisting well flushing pump 2 . at T 2 The working times of the hoisting well cleaning pump should not be less than 3 times, and the working time of each time can be determined according to the time taken by the hoisting well washing pump from the start of pumping to the time when the pumped water does not contain mud, sand and dirt. When the pumping capacity of the pump is small, its working time should be set longer, assuming that the pumped water before shutdown is relatively clean, free of mud, sand and impurities; when the pumping capacity of the well pump is large, the working time can be set shorter. It is also subject to the fact that the extracted water is free of mud, sand and impurities. The interval time between start-up and downtime of the hoist well flushing pump should not be less t...

The invention relates to a control circuit for return self-cleaning of a recharge well of a water source heat pump, which solves the automatic timing flushing problem of the recharge well. The invention comprises a pumping well water pump controller, a cycle time timer, an interrupted switching-on and switching-off timer, a return water pump controller in the recharge well and a necessary peripheral circuit. The invention is provided with an actuating unit which can set the accumulated working time of a suction pump, the time for stopping operation of the suction pump, the working time for flushing and the interval time of flushing for two times, and operates according to set time procedures together with the suction pump and a return flushing pump. The control circuit is characterized by simple system, low cost, reliable operation and obvious flushing effect, and is suitable for self-cleaning of the recharge well of the water source heat pump.
Description
technical field [0001] The invention belongs to the field of program automatic control, in particular to a control circuit for automatic backwashing of water source heat pump recharge wells. It is suitable for the automatic maintenance of the reinjection well, and can automatically complete the hoisting and cleaning of the reinjection well, ensuring the reliability of the reinjection and prolonging the life of the reinjection well. Background technique [0002] In the past, the maintenance of the reinjection well was very backward. Only after the water overflowed from the reinjection well, the reinjection well was maintained. The result was too late. The improper and untimely maintenance of the reinjection well made it difficult to ensure the reinjection water. The amount reaches the original design value, and even makes recharging impossible in severe cases. Seriously affected the promotion of energy-saving and environment-friendly products such as water source heat pumps,...
