Detailed Description
The structure of the integrated variable flow cooling water pump motor of the present invention will be further described with reference to specific embodiments to help those skilled in the art to more fully, accurately and deeply understand the technical solution of the present invention.
Example 1
In the embodiment, the impeller mechanism is additionally arranged at one end of the motor rotor shaft, and the impeller mechanism and the motor shell form the structure of the integrated water pump together. When the motor works, the impeller rotates along with the rotor, and the cooling water is pressed into the pipeline to replace the monomer water pump, so that the cooling water can be smoothly circulated. And the requirement of the cooling water flow is changed in order to adapt to different temperature changes of the cooling water of the motor. The impeller mechanism is designed into a flow-adjustable mode, so that the blade angle can be ensured to be reduced when the temperature of the motor is lower, and the energy consumption of the impeller is greatly reduced while the motor is cooled. When the temperature of the motor is higher and a larger cooling water amount is needed, the angle of the impeller is increased, and the cooling water flow is increased so as to meet the requirement of motor cooling.
Fig. 2 shows the motor structure of the integrated variable flow cooling water pump of the present embodiment, which includes a motor body 10, and an impeller mechanism 20 disposed inside the motor body 10. An axial water jacket 13 and a rear water jacket 14 are formed in a housing of the motor body 10, the axial water jacket 13 is communicated with the rear water jacket 14, a cooling water inlet 11 is formed on the axial water jacket 13, a cooling water outlet 12 is formed on the rear water jacket 14, a motor shaft 15 is arranged in the motor body 10, a sealing ring 16 is arranged between the motor shaft 15 and the housing, the impeller mechanism 20 is integrated at the rear end of the motor shaft 15, the impeller mechanism 20 is located in the rear water jacket 14, and preferably, an impeller main shaft 21 of the impeller mechanism 20 is arranged opposite to the cooling water outlet 12.
As shown in fig. 3 to 9, the impeller mechanism applied to the present embodiment includes an impeller main shaft 21, a blade bushing 22, blades 23, a return spring 24, and a heat induction ring 25. As shown in fig. 5, the front end of the impeller main shaft 21 is a mounting end, and the mounting end is provided with blade mounting posts, and the number of the blade mounting posts corresponds to the number of the blades. As shown in fig. 6, the blade 23 includes a blade body and a mounting base located at the bottom of the blade body, and the front end and the rear end of the mounting base are respectively provided with a blade mounting hole. As shown in fig. 7, the blade bushing 22 includes a bushing body and blade mounting posts on the bushing body, and the number of the blade mounting posts corresponds to the number of the blades. The heat induction ring 25, the blade bushing 22 and the return spring 24 are sequentially sleeved on the impeller main shaft 21 from the rear end of the impeller main shaft 21. The heat induction ring 25 is located between the mounting end of the impeller main shaft 21 and the blade bushing 22, the front blade mounting hole on the mounting base is mounted on the blade mounting post of the mounting end, and the rear blade mounting hole on the mounting base is mounted on the blade mounting post on the bushing body and can be fixed through a collar. The shaft body of the impeller main shaft 21 is mounted on the motor shaft 15 and such that the return spring 24 is disposed between the motor shaft 15 and the vane bushing 22. The inner diameter of the vane bushing 22 is larger than the diameter of the impeller main shaft 21 so that the vane bushing 22 can slide and rotate on the impeller main shaft 21 in the axial direction.
The temperature variation of the adaptable motor cooling water of integrated variable flow cooling water pump motor structure of this embodiment, and carry out automatic regulation to cooling water flow, it is higher at the motor temperature, when needing great cooling water volume, impeller angle grow, improve cooling water flow, and when satisfying motor cooling's requirement, and lower at the motor temperature, when the cooling water volume demand is less, can make the impeller angle diminish, reduce cooling water flow, when satisfying motor cooling, can show and reduce the impeller energy consumption. Specifically, in the present embodiment, the thermal sensing ring 22 is made of a thermal expansion material, and the length of the thermal expansion ring along the axial direction changes with the temperature change of the cooling water, when the temperature of the cooling water increases (meaning that the cooling requirement increases), the thermal expansion of the thermal sensing ring 22 pushes the blade bushing 22 to slide and rotate towards the direction of the return spring 24, so as to drive the mounting base to move and increase the angle of the blade body, so that the circulation of the cooling water can be accelerated, and the cooling effect is enhanced. And similarly, when the water temperature is reduced, the thermal sensing ring 22 contracts, and under the action of the return spring 24, the blade bushing 22 slides and rotates towards the thermal sensing ring 22, so that the blade angle is reduced, the circulation speed of cooling water is reduced, the cooling requirement can be met, and the energy consumption of the blade is reduced.
