Abstract

This utility model belongs to the field of mechanical equipment technology, specifically relating to a motor-driven pump unit with an adjusting component and a diesel engine. The motor-driven pump unit of this utility model is used with a diesel engine. The diesel engine has a housing, and the transmission assembly includes a first transmission gear and a second transmission gear. The first transmission gear is connected to the pump body, and the second transmission gear meshes with the first transmission gear and is used to connect to the diesel engine. The adjusting component is disposed between the pump body and the housing and is used to adjust the tooth backlash between the first and second transmission gears. By using the motor-driven pump unit of this technical solution, the adjusting component, disposed between the pump body and the housing, can adjust the tooth backlash of the first and second transmission gears in the stationary state of meshing, thereby avoiding out-of-tolerance problems. Furthermore, by selecting different adjusting components, the motor-driven pump unit can be adapted to various models of diesel engines, improving its applicability and versatility.
