Abstract
The utility model is an automatic electronic water pump, comprising an electric machine, a pump and an electronic control circuit. In the pump cavity are provided with a pressure sensor and a temp sensor respectively connected with the corresponding output terminals of the electronic control circuit, which are electrically connected with the electric machine via a relay. On the housing are arranged a LCD screen and an input button respectively connected with the display output terminal of the electronic control circuit and the set input terminal. The electronic control circuit is a single-chip computer circuit and the in the power wire of the electric machine is provided with a transformer, the output terminal of which is connected with the corresponding output terminal of the single-chip computer circuit. The pressure sensor and the control circuit can control accurately the pressure and regulate the pressure conveniently by the input button. Moreover, the electric machine can protect itself automatically in overheating and overloading because of the effect between the temp sensor with the transformer and the control circuit.
Description
Technical field
The utility model relates to water pump, particularly to the improvement of electric water pump.
Background technique
The electric water pump that uses in order to realize automatic control, is provided with pressure controller in pipeline at present, the low and setting value when hydraulic pressure, and pressure controller is connected the power supply of pump motor, pump working; When hydraulic pressure reaches the setting value upper limit, pressure controller cuts off the power supply of pump motor, and water pump quits work, and realizes the purpose of control automatically.But prior art can't realize control automatically in situations such as motor appearance heating, overloads, and owing to be by mechanical adjustment pressure, to low, the adjusting trouble of control accuracy of hydraulic pressure.
The model utility content
The utility model purpose be to provide the control of a kind of hydraulic pressure accurately, regulate easyly, and situations such as heating, overload occur at motor and realize the water pumps of control automatically, with convenient use.
Scheme of the present utility model is: electronic automatic water pump, comprise motor, the pump housing and electronic control circuit, in pump chamber, be provided with pressure transducer and temperature transducer, be connected with the respective input of electronic control circuit respectively, the output terminal of electronic control circuit is electrically connected with motor through relay, on housing, also be provided with liquid crystal display panel and input button, be connected with set input with the demonstration output terminal of electronic control circuit respectively.
Described electronic control circuit adopts single chip circuit.
The power line of motor is provided with mutual inductor, and the output terminal of mutual inductor is connected with the respective input of single chip circuit.
The utility model has the advantages that: owing in pump chamber, be provided with pressure transducer and temperature transducer,, can realize the accurate control of pressure, and adjust, when motor overheating, can protect automatically in addition by the input button is convenient by control circuit; The power line of motor is provided with mutual inductor, by control circuit, can realize overload protection.Compared with prior art, the utlity model has hydraulic pressure control accurately, regulate easy, the advantage of protection automatically.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is a structure sectional view of the present utility model.
Fig. 2 is an electric theory diagram of the present utility model.
Mark among the figure: 1 pump housing, 2 impellers, 3 pressure transducers, 4 temperature transducers, 5 motors, 6 control circuit boards, 7 control panels, 8 input buttons, 9 power supplys, 10 single chip circuits, 11 liquid crystal display panel, 12 relays, 13 mutual inductors.
Embodiment
As shown in Figure 1, embodiment's electronic automatic water pump comprises motor 5, the pump housing 1 and electronic control circuit, is provided with pressure transducer 3 and temperature transducer 4 in the exhalant canal of pump chamber.
In housing, be provided with control circuit board 6, also be provided with control panel 7 on the surface of shell.
In conjunction with Fig. 2, embodiment's control circuit adopts single chip circuit 10, be installed in jointly in the control circuit board 6 with power supply 9, relay 12 etc., pressure transducer 3 is connected with single chip circuit 10 corresponding pressure, temperature input end respectively with temperature transducer 4, the output terminal of single chip circuit 10 is electrically connected with motor 5 through relay 12, the power line of motor 5 is provided with mutual inductor 13, and the output terminal of mutual inductor 13 is connected with the current sample input end of single chip circuit 10.
Single chip circuit is common known technology, and its working principle no longer describes in detail.
During work, pressure transducer 3 and temperature transducer 4 in the exhalant canal of pump chamber are input to single chip circuit 10 with signal, in order to detect the temperature of hydraulic pressure and motor, when being lower than under the setting value, hydraulic pressure prescribes a time limit, single chip circuit 10 output signals, by 5 work of relay 12 control motors, water pump draws water.
Prescribe a time limit when hydraulic pressure is higher than on the setting value, single chip circuit 10 stops output signal, and motor 5 quits work.
Too high when motor 5 temperature, temperature transducer 4 is input to single chip circuit 10 with signal, and single chip circuit 10 stops output signal, and motor 5 quits work, and plays a protective role.
When motor 5 overloads, mutual inductor 13 is input to single chip circuit 10 with signal, and single chip circuit 10 stops output signal, and motor 5 quits work, and plays a protective role.
By the effect of each sensor and mutual inductor and single chip circuit, realized the automatic work of water pump, made things convenient for use.
