摘要： A drilling fluid pump system includes a plurality of modular pump units that are each driven by a linear electric motor. A control system that can include positional feedback information which is used to control all of the linear motors in the pump system and reduce pressure pulsation. The linear motors can be controlled to reduce fluid pressure pulsation by controlling velocity and relative timing between pistons. To accommodate removal and addition of individual pump units the pump modules can be isolated electrically and hydraulically. This can improve scalability, reliability, and serviceability of the pump system.

摘要： A piston pump includes a frame, a housing configured to be coupled to the frame via a fastener, an annular liner defining a chamber configured to receive a piston of the piston pump, and an annular liner lock flange circumferentially surrounding the annular liner. The annular liner lock flange includes a radially-extending portion configured to be positioned within a respective counterbore of the frame and a respective counterbore of the housing while the housing is coupled to the frame via the fastener to block relative movement between the liner lock flange, the frame, and the housing.
