Background technique
The electric water pump that uses at present in order to realize automatic control, is provided with pressure controller in pipeline, during lower than setting value, pressure controller is connected the power supply of pump motor, pump working when hydraulic pressure; When hydraulic pressure reaches the setting value upper limit, pressure controller cuts off the pump motor power supply, water pump quits work, and realize the purpose of control automatically, but there is following drawback in this control: at first, the words that water pressure fluctuations is larger, water pump will frequently be between open and close, and the energy consumption waste is large, and affects the working life of water pump, secondly, the pressure controller degree of regulation is lower; Again, the situation realization controls automatically such as heating appear at body, and by mechanical adjustment pressure, low to the hydraulic pressure control precision, regulate bothering and installing complexity.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of to control accurately and the integrated water pump sensing controler little to the water pump loss for the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of integrated water pump sensing controler, comprise pump sensor and be located at the electron pressure switch of pump sensor one side, it is characterized in that described pump sensor comprises housing and is located at the pressure transducer that is used for large flow control in housing and the thermistor sensing mechanism that is used for Small Flow Control, aforesaid housing has water output connector, water supply connector and lead riser, aforesaid lead riser inner end is connected with pressure transducer and thermistor sensing mechanism, and the outer end is connected with electron pressure switch.
A kind of integrated water pump sensing controler, comprise pump sensor and be located at the frequency-variable controller of pump sensor one side, it is characterized in that described pump sensor comprises housing and is located at the pressure transducer that is used for large flow control in housing and the thermistor sensing mechanism that is used for Small Flow Control, aforesaid housing has water output connector, water supply connector and lead riser, aforesaid lead riser inner end is connected with pressure transducer and thermistor sensing mechanism, and the outer end is connected with frequency-variable controller.
When hydraulic pressure during lower than setting value, pump working, during at the above small flow of setting value, pressure transducer quits work when hydraulic pressure, the work of thermistor sensing mechanism, water pump can also work on; When lack of water and current overload, water pump quits work.
Further, described thermistor sensing mechanism comprises the first thermistor, the second thermistor and heater, aforesaid the first thermistor and the second thermistor interval setting, and aforesaid heater contacts setting with the first thermistor.
Further, a side of described housing has the smooth face that arranges of supplied for electronic pressure switch or frequency-variable controller installation.
Compared with prior art, the utility model has the advantage of: pressure transducer and thermistor sensing mechanism Integral design, to work in coordination with and complete accurate control, the assurance water pump is stably worked under state, is conducive to reduce energy consumption and extends the water pump life time.
