2, the water inlet water shortage is monitored arbitration functions automatically;

3, can start automatically after incoming call and water inlet water level recover again after having a power failure and resume operation;

When 4, seasoning oneself to cold the area use, the anti-function of freezing to death of water pump that can prevent to freeze and damage even water pump stops to supply water, still can be rotated slowly;

5, be suitable for the multiple sensors signal,, not limit by condition, use convenient as adopting resistance teletransmission pressure meter, electro connecting pressure gauge or pressure switch, pressure transmitter etc.;

6, the automatic detection alarm of water supply fault, too high as hydraulic pressure, hydraulic pressure is on the low side, low water stage termination of pumping etc.;

7, perfect motor defencive function is as: operating overload, short circuit, overheated, overvoltage, under-voltage etc.;

8, incorporate structure design, the deployment cost and the institute that have reduced equipment take up space;

9, according to situations such as hydraulic pressure and water supply volumes, the quantity of water pump is opened in decision, and the hydraulic pressure that can use place, the mouth of a river keeps constant, and good energy-conserving effect;

10, in the course of the work, double pump can have days off by turns, and is used alternatingly;

11, when one of them water pump breaks down, can control water pump by intelligent controller, to realize the automatic conversion of two water pumps.
