Detailed Description

The present invention will be described in detail with reference to the attached drawings, and other advantages and effects of the present invention can be easily understood by those skilled in the art from the disclosure of the present specification. In the present specification, the terms "upper", "lower", "left", "right", "middle", and the like are used for the sake of clarity, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also regarded as the scope of the present invention without substantial changes in the technical content.

Example (b):

as shown in fig. 1, for the utility model discloses a conduction oil pump with good leakproofness, including base 1, the pump body 2 and motor 3 are installed on base 1, link to each other through pump head 21 and rotor 31 between the motor 3 and the pump body 2, are connected with heat sink 4 through support 41 on the base 1 of pump head 21 and rotor 31 junction below, it has air-supply line 44 to connect to lead to on the outer wall of heat sink 4, and heat sink 4 cools down through air-supply line 44 connection compressed air source to the junction of pump head 21 and rotor 31. The pump head 21 is connected with a thermocouple sensor 211 for high temperature early warning.
