Opposed multi-cylinder slurry pump crankshaft direct driving force structure

The utility model discloses an opposed multi-cylinder slurry pump crankshaft direct driving force structure, which relates to the technical field of petroleum drilling and production equipment and comprises a slurry pump main machine, a mounting flange, a flexible compensation coupling, a motor bracket, a driving motor and a cooling fan. The stator parts of the driving motor are fixed on the outer sides of the main wallboards on the two sides of the slurry pump main machine through the mounting flanges, the rotor parts are connected with the crankshaft through the flexible compensation coupler, the driving motor directly drives the crankshaft to rotate, the transmission structure is simplified, and power consumption is remarkably reduced; meanwhile, vibration generated when the slurry pump works is reduced by using the flexible compensation coupler; compared with a traditional multi-cylinder single-action reciprocating piston pump, the multi-cylinder single-action reciprocating piston pump solves the problems
