PUMP DRIVETRAIN DAMPER SYSTEM AND CONTROL SYSTEMS AND METHODS FOR SAME

摘要

In one aspect, there is provided a damper control system for a reciprocating pump assembly according to which control signals are sent to electromagnets. In another aspect, there is provided a method of dampening vibrations in a pump drivetrain according to which a beginning of torque variation is detected and at least a portion of the torque variation is negated. In another aspect, signals or data associated with pump characteristics are received from sensors, torque characteristics and damper response voltages per degree of crank angle are calculated, and control signals are sent to electromagnets. In another aspect, a damper system includes a fluid chamber configured to receive a magnetorheological fluid; a flywheel disposed at least partially within the fluid chamber and adapted to be operably coupled to a fluid pump crankshaft; and a magnetic device proximate the flywheel. The magnetic device applies a variable drag force to the flywheel.

1. A damper control system for a reciprocating pump assembly, the damper control system comprising:
at least one sensor adapted to sense at least one characteristic of the reciprocating pump assembly, the reciprocating pump assembly having opposing first and second end portions and being adapted to be operably coupled to at least one gear reducer at the first end portion; at least one processor in communication with the at least one sensor; a non-transitory computer readable medium operably coupled to the at least one processor; and a computer program stored on the non-transitory computer readable medium and executable by the at least one processor; wherein the execution of the computer program by the at least one processor is adapted to cause one or more control signals to be sent to one or more electromagnets located at the second end portion of the reciprocating pump assembly; and wherein the one or more control signals are adapted to be sent in response to the at least one processor receiving from the at least one sensor signals or data associated with the at least one characteristic of the reciprocating pump assembly.
