Abstract
The utility model discloses a water pump with a water-shortage protection device, which comprises a pump body and a motor connected with the pump body. The motor is connected with a reset switch through a power cord, the motor and the reset switch are connected with a thermal protector component through the power cord, the thermal protector component is mounted outside or inside the pump body, and the motor is protected through the thermal protector component. The water pump is designed with the internal thermal protector component, an idling circuit of the water pump is protected, and overheating of the water pump caused by various reasons such as pipe blocking and the like is avoided, safety of the water pump is improved, service life of the water pump is prolonged, and the water pump has high practical value.
Description
Technical field
The utility model relates to a kind of water pump, particularly a kind of water pump that has the excessive low water level protection device.
Background technique
The ground water pump in use usually owing to a variety of causes such as water pipe obstructions, causes water pump not take out water; Make pump motor be in the no-load running state, and the water that stay in the water pump this moment is under the effect of high-speed rotating impeller, high-speed motion in water pump; Huge energy changes into heat energy; Cause the temperature of residuary waters to rise rapidly, reach very high-temperature, the normal use of harm water pump material and part; Even cause serious accident, therefore be necessary to design the technology that makes new advances to address the above problem.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides the water pump that has the excessive low water level protection device.
The utility model solves the technological scheme that its technical problem adopted:
A kind of water pump with the excessive low water level protection device; Comprise the pump housing and with the joining motor of the pump housing; Said motor is connected with reset switch through power line; Be connected with the heat protector assembly through power line between said motor and the reset switch, this heat protector assembly is installed in the outside or the inboard of the pump housing, plays the effect of protection motor through the heat protector assembly.
In order to make the operator can know in time that water pump is unusual, said heat protector assembly is connected in parallel to warning light.
The user observes for ease, and warning light is integrated to be installed in the reset switch.
In order to protect the heat protector assembly, said heat protector assembly is provided with copper pipe outward, and copper pipe plays the effect that the water temperature in the water pump is transmitted to fast the heat protector assembly simultaneously, and heat protector assembly and copper pipe are fastening through the heat conduction sealer.
In order further to improve reliability, said heat protector assembly is the thermistor-type heat protector.
The beneficial effect of the utility model is: this water pump is through the design of built-in heat protector assembly; Realize the protection of water pump idler circuit; Avoided helping to improve the Security and the working life of water pump, had good practical value because a variety of causes such as water pipe obstruction cause the water pump superheating phenomenon.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of heat protector assembly external in the utility model;
Fig. 2 is the built-in structural representation of heat protector assembly in the utility model;
Fig. 3 is the circuit connection diagram of the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3.A kind of water pump with the excessive low water level protection device, comprise the pump housing 4 and with the pump housing 4 joining motors 1, wherein motor 1 plays and drives the effect that water pump draws water, motor 1 can adopt general single phase motor, installs additional can mate the 220V/110V power supply behind the electric capacity 11 and use.Said motor 1 is connected with reset switch 3 through power line, is connected with heat protector assembly 2 through power line between said motor 1 and the reset switch 3, and this heat protector assembly 2 is installed in the outside or the inboard of the pump housing 4, plays superheat protecting function.In order to guarantee that said heat protector assembly 2 is thermistor-type heat protectors, i.e. the heat protector of PTC heating, the heat protector of comparing other type more can adapt to the Environmental Conditions of water pump.The said heat protector assembly 2 outer copper pipes 6 that are provided with, heat protector assembly 2 is fastening through the heat conduction sealer with copper pipe 6, and copper pipe 6 plays the effect that protection heat protector assembly 2 is transmitted to the water temperature in the water pump heat protector assembly 2 simultaneously fast.
In order to make the operator can know in time that water pump is unusual, said heat protector assembly 2 is connected in parallel to warning light 5, these warning light 5 integrated being installed in the reset switch 3.When temperature just often, heat protector assembly 2 is connected, warning light 5 can not lighted owing to resistance is in by short-circuit condition greatly, and breaks off when triggering temperature when heat protector assembly 2 reaches, warning light 5 is lighted with regard to being in normal on-state.
When real work, when water pump is in (when residuary waters is arranged) under the no-load running state, heat protector assembly 2 is when reaching predetermined temperature; Circuit is cut off in action, and water pump is out of service, and warning light 5 lights simultaneously; Remind operator's fault to take place, heat protector assembly 2 under the effect of heater band, maintaining heat protector assembly 2 temperature-resistant; And can not automatically reset, after the operator fixes a breakdown, break off the protection special use reset switch 3 is set; Heat protector assembly 2 begins to cool down, and reaches reset temperature and automatically resets, and water pump begins normal operation then.
The utility model is through the design of built-in heat protector assembly 2; Realize the protection of water pump idler circuit; Avoided helping to improve the Security and the working life of water pump, had good practical value because a variety of causes such as water pipe obstruction cause water pump body and the motor 1 overheated damage that causes water pump.
