Technical field
The utility model relates to water pump, particularly to the improvement of portable electric water pump.
Background technique
Present hand held, electric water pump, it is the simple combination of pump and motor, its structure comprises motor, the pump housing and the housing that has handle, the motor and the pump housing are installed in the housing jointly, impeller in the pump housing is connected with the rotating shaft of motor, the driven by motor wheel rotation is used for water lift or to water pressurization operation.Because portable water pump is usually used in some nonspecific purposes, and working environment is changeable, as water, water lift etc. in water lift, the river in water lift, the pond, lake in the flushing, well, because inhale that journey varies in size, the influence of factors such as water-outlet quantity size variation and water source changed condition, existing portable water pump does not have automatic controller, thereby cause output unstable, and need often to regulate, cause and use inconvenience.
Summary of the invention
The utility model purpose is to provide a kind of portable water pump with automatic controller, uses with convenient.
Scheme of the present utility model is: a kind of portable water pump, the motor and the pump housing are installed in the housing that has handle jointly, impeller in the pump housing is connected with the rotating shaft of motor, in the pump housing, be provided with sensor, be provided with control panel at surface of shell, sensor and control panel respectively be located at housing in the control circuit input end be electrically connected, the control circuit output terminal is electrically connected with motor, sensor comprises pressure transducer and temperature transducer; Be provided with modulating valve between the water intake of the pump housing and pump chamber; Be provided with damping cavity between the pump chamber of the pump housing and water outlet, be provided with the damping ball in the damping cavity.
The utility model has the advantages that: owing to be provided with sensor in the pump housing,, regulate the working state of motor,, reach the purpose of automatic control simultaneously by control panel input setup parameter by the effect of control circuit.In addition, be incorporated into the modulating valve between the mouth of a river and pump chamber and the effect of the damping ball in the damping cavity, make the waterflow stabilization of output, evenly, improved using effect.
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 housing, 2 control circuits, 3 control panels, 4 motors, 5 pump housings, 6 impellers, 7 water outlets, 8 modulating valve, 9 water intakes, 10 pump chambers, 11 damping cavity, 12 damping balls, 13 sensors.Wherein 41 is machine shafts; The 61st, impeller shaft; The 81st, the valve body of modulating valve, 82 valve plugs, 83 springs; The 131st, pressure transducer, 132 temperature transducers.
Embodiment
As shown in Figure 1, embodiment's portable water pump comprises motor 4, the pump housing 5 and the housing 1 that has handle, motor 4 is installed in the housing 1 jointly with the pump housing 5, impeller 6 is located in the pump chamber 10 of the pump housing 5, impeller shaft 61 is connected with the rotating shaft 41 of motor 4, is provided with sensor 13 in the damping cavity 11 in the pump housing 5, is provided with control panel 3 on housing 1 surface, respectively be located at housing 1 in control circuit 2 input ends be connected, control circuit 2 output terminals are connected with motor 4.Motor 4 impeller 6 are rotated, and water is sucked from water intake 9, discharge from water outlet 7, and present embodiment adopts four-stage pump, to produce high hydraulic pressure.Control circuit 2 is according to the parameter of sensor 13 and the setting value of control panel 3 inputs, the work of control motor 4.
Be provided with modulating valve 8 between the water intake 9 of the pump housing 5 and the pump chamber 10, modulating valve 8 comprises valve body 81, valve plug 82, spring 83, is shaped on conical internal cavity in the valve body 81, is provided with valve plug 82 and spring 83 in the inner chamber.When the water pressure difference inside and outside the pump chamber 10 was big, valve plug 82 was open, and inflow increases; Pressure difference hour, valve plug 82 are by spring 83 jackings, and inflow reduces, and help the water outlet stable water pressure of pump.
7 of the pump chamber 10 of the pump housing 5 and water outlets are provided with damping cavity 11, are provided with damping ball 12 in the damping cavity 11, and water flows into damping cavity 11 from pump chamber 10 after being pressurizeed by impeller 6, under the effect of inertia of damping 12 balls, have guaranteed that water velocity is equably from water outlet 7 outputs.
Referring to Fig. 2, sensor 13 comprises pressure transducer 131 and temperature transducer 132, and the input end with control circuit 2 is connected respectively.Control circuit 2 adopts known single chip circuit, because control circuit 2 is common employing pressure, temperature controlled prior art, its working principle no longer is described in detail here.
During work, when water outlet 7 is closed or stopped up, hydraulic pressure raises, and control circuit 2 automatic control motors 4 quit work; When water intake 9 lacks of water, water outlet 7 hydraulic pressure are low excessively, and control circuit 2 also automatic control motor 4 quits work; Overheated when motor 4, by temperature transducer 132 perception, control circuit 2 automatic cut-off motors 4 power supplys prevent to burn.
By control panel 3, can set the delivery pressure value, the various working staties of electric pump also show on control panel 3.
By single chip machine controlling circuit, water pump can be realized automatic control, has made things convenient for use.In addition,, make the waterflow stabilization of output, evenly, improved using effect in conjunction with the effect of the damping ball in modulating valve and the damping cavity.
