Heat-dissipation pump body structure of civil aviation engine

The invention discloses a heat-dissipation pump body structure of a civil aviation engine. The heat-dissipation pump body structure comprises a pump body and a pump cover arranged on the left side ofthe pump body; an inserting groove and an inserting hole are distributed in the edge of the left side of the pump body; a first screw hole is further formed in a hole cavity of the inserting hole; andthe right side of the pump cover is connected to the left side of the pump body through a stability augmentation mechanism. According to the heat-dissipation pump body structure, the pump cover can be rapidly installed on the pump body, the convenient installation performance of the pump cover is improved, meanwhile, the overall firmness of the pump cover during installation is greatly improved,it is guaranteed that the pump cover is installed on the pump body in a balanced and stable manner all the time, and shaking abrasion generated between the pump cover and the pump body when a heat-dissipation pump is used is re
