abstract

Mud pump is an important component of drilling equipments, which transports flush fluid like mud or water into bore in order to cool drill and carry debris. In this paper, a novel radial mud pump directly driven by permanent magnet disc synchronous motor (PMDSM) is designed, the influence of different numbers of plunger cylinders on the pump’s flow pulsation is analyzed to determine the pump’s configuration and driving requirement, and the structure and performance parameters of the direct drive PMDSM are calculated by finite element analysis. Compared with conventional mud pumps, the novel pump is characteristic that the structure is simple, working stability and efficiency are greatly improved, also the life of the equipment is extended.
