Pump, also referred to as water pump, is conveying liquid or the machinery making fluid pressurization.It sends the mechanical energy of prime mover or other external energy to liquid, and liquid energy is increased.Pump is mainly used to the liquid such as conveying water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal, also can conveying liquid, gas mixture and the liquid containing suspended solids.Former for power machine combines with the pump housing by kinetic pump exactly, and power equipment and the pump housing usually use coupling to come two and connect, and being in transmission connection of conventional Pump and Electromotor is motor shaft and pump assembly direct-drive or by contact-type shaft coupling transmission.But as the urea liquid in urea pump has corrosivity to common metal material, so urea pump does not allow the urea liquid of transport pump in the running of pump to outward leakage, but the organization plan pump housing of conventional pumps and transmission place of motor are necessarily connected, be difficult to meet urea pump usage requirement.Once urea liquid leaks into coupling position in these pumps, damage will inevitably be caused to coupling, greatly have impact on the working life of kinetic pump.When traditional coupling uses on kinetic pump simultaneously, excessive once the end resistance be connected with the pump housing, have the stall that can cause coupling and motor shaft, and the power of motor is still in lasting input, thus causes the heating value of motor to increase, motor is burnt out.
Model utility content
For above-mentioned problem, the purpose of this utility model is the kinetic pump magnetic coupling shaft joint providing a kind of two sections of coupling being connected to the pump housing and motor to be separated from each other.
The utility model solves the technological scheme that its technical problem adopts: this kinetic pump magnetic coupling shaft joint is used in kinetic pump, it comprises the pump magnetic coupler being disc-shape, the motor magnetic coupler that are loaded on enclosure, identical, the coaxial assembling relatively of the surface size of the two integrated disc portions; The axial portions of described pump magnetic coupler is by output shaft and the pivot joint of pump housing rotating part, described motor magnetic coupler is by the rotating shaft pivot joint of input shaft and motor, described input shaft, output shaft are separated from each other assembling, and described pump magnetic coupler outer wrap has the capsul separated with described motor magnetic coupler; On described pump magnetic coupler and the just right disk of described motor magnetic coupler, circumference is evenly equipped with same even number magnetic patch respectively; The magnetic line of force of the respective magnetic patch on described pump magnetic coupler and described motor magnetic coupler disk and disc shaft line parallel, the magnetic with the adjacent magnetic patch of dish is contrary, i.e. same magnetic interval assembling.
As preferably, described magnetic patch is fan-shaped, be assemblied in described pump magnetic coupler and described motor magnetic coupler disk separately in disc-shaped surface magnetic patch form toroidal.
As preferably, described magnetic patch is made up of rare earth magnetic steel.
As preferably, described capsul is just processed with pilot hole to the inner side of described motor magnetic coupler disc face axis, and the end that described output shaft stretches out described pump magnetic coupler is assemblied in described pilot hole.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
As shown in the embodiment shown in fig, this kinetic pump magnetic coupling shaft joint is used in kinetic pump, and it comprises the pump magnetic coupler 2 being disc-shape, the motor magnetic coupler 3 that are loaded on shell 1 inside, identical, the coaxial assembling relatively of the surface size of the two integrated disc portions; The axial portions of described pump magnetic coupler 2 is by output shaft 4 and the pivot joint of the pump housing 5 rotating part, described motor magnetic coupler 3 is by the rotating shaft pivot joint of input shaft 6 with motor 7, described input shaft 6, output shaft 4 are separated from each other assembling, and the described pump housing 5 and pump magnetic coupler 2 outer wrap have the capsul 8 separated with described motor magnetic coupler 3; On the disk that described pump magnetic coupler 2 is just right with described motor magnetic coupler 3, circumference is evenly equipped with same even number magnetic patch 9 respectively; The magnetic line of force of the respective magnetic patch 9 on described pump magnetic coupler 2 and described motor magnetic coupler 3 and disc shaft line parallel.With the magnetic i.e. same magnetic interval assembling on the contrary of the adjacent magnetic patch 9 of dish; As shown in Figure 2, black represents a magnetic face of magnetic patch 9, and white represents another magnetic face of magnetic patch 9.
This kinetic pump magnetic coupling shaft joint is mainly used in the kinetic pump that corrosion class solution transmits as urea liquid, this coupling two sections of being off, by magnetic force transmission, its working principle is, motor 7 drives described motor magnetic coupler 3 to rotate by input shaft 6, due to pump magnetic coupler 2, magnetic patch 9 on motor magnetic coupler 3 disk is spaced respectively, magnetic patch 9 near the opposite pole face of oneself on the inevitable suction pump magnetic coupler 2 of magnetic patch 9 on motor magnetic coupler 3 follows rotation, such two Couplers just can act on conduction when directly not contacting, and the pump housing 5 and whole pump magnetic coupler are directly closed by described capsul 8, the leakage of the etchant solutions such as urea can be prevented.This by magnetic-coupled coupler structure, having dissolved conventional pumps dexterously cannot the technical barrier of the corrosive solution such as transport urea.Compact structure, rationally distributed, effectively avoid the harmful effect being difficult to seal, urea liquid leakage causes corrosion to motor 7 and other parts caused by the direct transmitting torque of the input shaft 6 of motor 7, the High Rotation Speed moment of torsion of motor 7 is delivered on pump magnetic coupler simultaneously, pump magnetic coupler 2 has pawl cover to be connected with the pump housing 5 gear internal rotor, drives the pump housing 5 normal safe high-efficiency operation.Improve the working life of whole kinetic pump, reduce user cost.And in the process of magnetic drives, even if the resistance be subject to when the pump housing 5 draws water is excessive when causing output shaft 4 stall, also can not affects the rotation of electric machine main shaft, effectively protect motor 7.
