But the effect of lubricating oil.
Beneficial effects of the present invention are：
It is cold that cooling water of the structure of the present invention by the lubricating oil in bearing in pump shaft internal circulation flow, with impeller carries out heat exchange
But, finally the lubricating oil for having cooled down is sent to into the higher region of temperature in bearing, realizes the cooling to bearing.Can be effectively sharp
The equipment for not needing other outside with the cooling water of pump itself are effectively cooled down to bearing, and can be to a certain extent
Realize the thermal balance of pump shaft.
