Road design, makes cooling pump that can form balanced hydraulic pressure at each speed, forms Forced water cooling to engine heating position.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model cooling pump.
Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model technology.It should be appreciated that specific embodiment described herein is only used to
It explains the utility model, is not used to limit the utility model.
As shown, high-power engine cooling pump, including the engine pump housing 1, impeller 2, the impeller disk 3 and impeller shaft 4, institute
It states impeller 2 to be mounted on the impeller disk 3, the impeller disk 3 is mounted in impeller shaft 4, and the impeller shaft 4 is connected on the pump housing 1；Institute
The end for stating impeller shaft 4 is provided with longitudinal bolt connecting hole 41, and the impeller disk 3 is fixed on the end of impeller shaft 4 by bolt 5
Portion；The inner end of the impeller shaft 4 is provided with a bearing 6, and the outer end of impeller shaft 4 is provided with mechanical seal 7, the impeller shaft 4
It is rotated under the control of bearing 6 and mechanical seal 7 simultaneously.
Further, wound impeller axis 4, and oil sealing 8 is additionally provided between bearing 6 and mechanical seal 7.
It further include pump cover 9, the pump cover 9 is fixed on the pump housing 1 by bolt 10, and the pump cover 9 is collectively formed with the pump housing 1
Impeller rotating drum 11, disengaging water channel 12, the disengaging water channel 12 is connected to impeller rotating drum 11, so that cooling water obtains continuously not
