Description
Technical field
The utility model relates to a kind of water pump, particularly relates to a kind of pump equipment with current-limiting protection function.
Background technique
Field needs a large amount of water resources pourings, is a necessary selection with pumping for water pump.When pump working overlong time, electric current is excessive causes short circuit; In the process of drawing water, be easily extracted into handstone, because power transmission is excessive, water pump will be burnt out when water pump is blocked do not turn by handstone, cause damage.After outdoor water tank has been expired, water has outbound flowed, and enclosed water tank, water is beaten always, and water completely also continues to beat, and the pressure in water tank can be very large, very easily suffocates and causes motor to burn out.
Model utility content
In order to overcome above-mentioned technical problem, the utility model provides a kind of pump equipment with current-limiting protection function.
The utility model is achieved in that a kind of pump equipment with current-limiting protection function, and it comprises water pump, current-limiting protection device, and described water pump comprises power supply, motor, shell, and described current-limiting protection device comprises limiting protector and voltmeter; One end of described limiting protector is electrically connected one end of described power supply via described motor, the other end of described power supply is electrically connected the other end of described limiting protector, and described voltmeter is parallel to described power supply; Described voltmeter is fixed on the outside of described shell.
As the further improvement of such scheme, described limiting protector is safety fuse cutout.
As the further improvement of such scheme, described limiting protector is air valve.
As the further improvement of such scheme, described voltmeter is fixed in the outer top surface of described shell.
As the further improvement of such scheme, described limiting protector is housed in described shell.
As the further improvement of such scheme, described voltmeter is fixed in the outer lateral side of described shell.
As the further improvement of such scheme, above described shell, be provided with handle.
The utility model is by design current-limiting protection device, entering water pump once foreign material such as having handstone when water pump is worked in field causes water pump idle running to draw water, the limiting protector of current-limiting protection device just disconnects, and Pump Failure obtains protection, thus prevents water pump from burning out; In addition, enclosed water tank, also continue to fetch water if water is completely rear, water tank internal pressure will be caused too high, cause the motor of water pump to dally, therefore limiting protector also just disconnects, and can not produce situation motor being burnt out because water tank is suffocated and occur.
On the other hand by observing voltmeter, just can know and see voltage condition intuitively, that operate water pump is generally the general lower peasant of educational level, they probably not to know on earth by current-limiting protection, or say not energising, the true cause of Pump Failure can not be made clear, but it is just different after having had voltmeter, as long as power-on voltage table must have index, therefore whether index is had by observing voltmeter, whether just can very easy to doly know by current-limiting protection, and observe voltmeter and whether have index to be just that illiteracy will also can accomplish, therefore but the utility model structure is simple very practical, through overtesting, receive the warm welcome of vast farmers friend, but technology not necessarily want superb must from the practical standpoint of peasant, could be promoted in vast farmers friend and apply like this.
Accompanying drawing explanation
The structural representation with the pump equipment of current-limiting protection function that Fig. 1 provides for the utility model better embodiment.
Fig. 2 is the electrical block diagram of the pump equipment in Fig. 1 with current-limiting protection function.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See also Fig. 1 and Fig. 2, the pump equipment of current-limiting protection function that what the utility model better embodiment provided have comprises water pump 1 and current-limiting protection device.Water pump 1 comprises power supply (not shown), motor 5 (in order to make those skilled in the art understand circuit diagram easily, representing in fig. 2 with conventional tag M), shell 2.Described current-limiting protection device comprises limiting protector K and voltmeter 3, (in order to make those skilled in the art understand circuit diagram easily, representing in fig. 2 with conventional tag V).
One end of limiting protector K is electrically connected one end of described power supply via motor 5, the other end of the other end electrical connection limiting protector K of described power supply, described voltmeter 3 is parallel to described power supply.Described voltmeter 3 is fixed on the outside of described shell 2.
When water pump 1 works in field, once have the foreign material such as handstone to enter water pump 1, when causing water pump 1 idle running to draw water, the limiting protector K of current-limiting protection device just disconnects, and water pump 1 power-off obtains protection, thus prevents water pump 1 from burning out; In addition; when water tank is enclosed water tank; also continue to fetch water if water is completely rear; water tank internal pressure will be caused too high; the motor 5 of water pump 1 is caused to dally; therefore limiting protector K also just disconnects, and water pump 1 power-off obtains protection, can not produce situation motor 5 being burnt out because water tank is suffocated and occur.
The voltmeter 3 be fixed on the outside of shell 2 is very useful, by observing voltmeter 3, just can know and seeing voltage condition intuitively.Operation water pump 1 be generally the general lower peasant of educational level, they probably do not know on earth by current-limiting protection, or say and be not energized, and can not make the true cause of water pump 1 power-off clear.But it is just different after having had voltmeter 3; as long as power-on voltage table 3 must have index; whether therefore whether there is index by observing voltmeter 3, just can very easy to doly know by current-limiting protection, and observe voltmeter 3 and whether have index to be just that illiteracy will also can accomplish.Therefore but the utility model structure is simple very practical, through overtesting, receive the warm welcome of vast farmers friend, but technology not necessarily wants superb from the practical standpoint of peasant, could must being promoted in vast farmers friend and applying like this.
Limiting protector K can be safety fuse cutout, can be also air valve, preferably adopt air valve, so just need not break as safety fuse cutout and will change, only need unshorting factor, just can recover air valve and connect.Limiting protector K is preferably housed in described shell 2, avoids the external world to touch impaired.
Described voltmeter 3 is fixed in the outer lateral side of described shell 2, and such placement can not be damaged voltmeter 3 by pressure.Described voltmeter 3 can be fixed in the outer top surface of described shell 2, also can be fixed in the outer lateral side of described shell 2, only otherwise damaged by pressure by water pump 1.Conveniently move or carry water pump 1, shell 2 can also be provided with handle 4 above.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
