Abstract
The utility model discloses a kind of water pump water shortage protective device, solve the problem that water pump dallies in water-stressed conditions.The technical scheme used: a kind of water pump water shortage protective device, is arranged on the lateral surface of the pump housing, including housing; it is characterized in that, housing is axially arranged along water pump, is provided with two electrodes separated in housing; electrode electrically connects with water pump controller, and enclosure interior communicates with the external world.This water pump water shortage protective device simple in construction, cost are low, and stability in use is good.
Description
Technical field
This utility model relates to a kind of water pump, especially relates to a kind of scarce for being directed at water pump at water head site water level decreasing
During water, water pump is provided the device of protection.
Background technology
Water pump is when pump water operation, when the water in pond or well is taken out to the greatest extent, and water pump only can dally, and this not only wastes electricity
Can, but also water pump can be easily caused damage because water pump idle running heats up.The water with water-shortage protection device of existing commercial type
Mostly with a kind of electron pressure switch in pump, this pressure switch is for detecting the hydraulic pressure in water pump, relatively low at hydraulic pressure
In the case of, pressure switch can disconnect the power supply of water pump.On the one hand this pressure switch involves great expense, and result in this with lacking
The water pump of water conservation device holds at high price；On the other hand, this pressure switch fragile and cause lost efficacy.
Utility model content
This utility model technical issues that need to address are: provide a kind of novel water pump water shortage protective device, this protection
Apparatus cost is low, using effect good.
The technical scheme that this utility model is taked: a kind of water pump water shortage protective device, is arranged on the lateral surface of the pump housing, bag
Include housing, it is characterised in that housing is axially arranged along water pump, in housing, be provided with two electrodes separated, electrode and water pump
Controller electrically connects, and enclosure interior communicates with the external world.Two electrodes contact with water simultaneously, under the electric action of water, and two electricity
Pole turns on, water pump controller conducting water pump, makes pump operation.Under exsiccosis, two electrodes are not turned on, water pump controller
Can not get coming from the signal of two electrodes, water pump quits work.
Electrode is cylindric.Cylindrical electrode is drawn materials conveniently, and electrode typically selects stainless steel, or copper material
Matter.
Arranging two strip holes on housing, two strip holes are the most corresponding with two electrode positions, and strip hole is used for water
Flow to and flow out.It is directly tactile with electrode fast connecting that this is easy to water.
The bottom of strip hole and housing bottom have certain distance.In the case of being provided with strip hole, will not be to housing
Intensity and durability cause big impact.
Housing bottom is uncovered, and water can flow to from the bottom of housing and flow out so that electrode can reflect water truly
Position situation.
Integrally formed with the gusset piece for being connected and fixed with the pump housing on housing side.Being provided for of gusset piece realizes shell
Fixing between the body pump housing.
The lower end of electrode and the bottom of housing have a certain distance.Distance between them is with during water pump real work
Safety level is corresponding, as long as electrode can sense real water level, water pump can trouble free service, it is ensured that pump working
Smoothness.
The beneficial effects of the utility model: water pump is provided with this water-shortage protection device, it is possible to the normal work for water pump carries
For ensureing, it is ensured that the service life of water pump.Utilizing two electrodes to come perception water level, simple in construction, cost is low.These two electrodes
Perception direct to water level, it is possible to reflect the truth of water level well, the stability in use of this water-shortage protection device is good.
Accompanying drawing explanation
Fig. 1 is the front view of the water pump with this water-shortage protection device.
Fig. 2 is the left view of the water pump with this water-shortage protection device.
Detailed description of the invention
Seeing in figure, this water pump water shortage protective device arranges on the lateral surface of pump body, for being electrically connected with water pump controller
Connect, when two electrodes are all plugged in water, it is possible to turn on pump working by water pump controller, and insert at two electrodes the most simultaneously
When receiving in water, when that is to say water level deficiency, water pump controller is cut off the electricity supply, water air pump inoperative.
This water pump water shortage protective device includes that housing 1, housing 1 are working of plastics, integrally formed with gusset piece 4 on housing 1, and connection
Fishplate bar 4 is fixed on the lateral surface of the pump housing by trip bolt, and then realizes the fixing of housing 1 and water pump.It is spacious bottom housing 1
Mouthful, housing 1 is axially arranged along water pump.
The lateral surface of the pump housing is provided with two columned electrodes 3 separated, the water pump that electrode 3 is set with in water pump
Controller is connected.These two electrodes 3 are positioned at housing 1, are provided with two strips corresponding with electrode 3 position on housing 1
Hole 2, that is to say that an electrode 3 is positioned at the inner side of a strip hole 2.The bottom of strip hole 2 and electrode 3 and housing 1 has necessarily
Distance, electrode 3 is for being hung on the pump housing, and the lower end of electrode 3 also has a certain distance with the bottom of housing 1.
Claims (3)
1. a water pump water shortage protective device, is arranged on the lateral surface of the pump housing, including housing, it is characterised in that housing is along water
Pump is axially arranged, is provided with two electrodes separated in housing, and electrode electrically connects with water pump controller, and enclosure interior is with extraneous
Communicating, electrode is cylindric, arranges two strip holes on housing, and two strip holes are the most corresponding with two electrode positions, long
The bottom of cylindrical void and housing bottom have certain distance, and housing bottom is uncovered.
Water pump water shortage protective device the most according to claim 1, it is characterised in that integrally formed with being used on housing side
The gusset piece being connected and fixed with the pump housing.
Water pump water shortage protective device the most according to claim 1 and 2, it is characterised in that the lower end of electrode and the end of housing
Portion has a certain distance.
