Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further details to the utility model：
The utility model discloses a kind of cooling structure of hot oil pump, for being cooled down to hot oil pump, ensures hot oil pump
Bearing and seal assembly do not influenceed by high temperature.
Cooling structure in the utility model is arranged on hot oil pump, and hot oil pump is used to carry out hot-oil circulation.Hot oil pump bag
The pump housing 2 that pump cover 1 is set is included, hot oil inlet and hot oil outlet are set on the pump housing 1.The inner chamber of the pump housing 1 is set drives rotation by pump shaft 5
The impeller 6 turned.It is provided for installing the bearing body 4 of bearing 3 in the side of pump cover 1.Pump shaft 5 is located in the pump housing 2 through pump cover 1
Impeller 5 is fixedly installed in end, and the other end of pump shaft 5 crosses bearing body 4 and the bearing fit in bearing body 4, then connected with motor
Connect, work is driven by motor.Cooling structure in the utility model is provided between pump cover 1 and bearing body 4, cooling
