    Abstract: A pump monitoring system for use in wellbore operations includes a strain gauge that can be positioned on a fluid end of a pump and at least one pressure transducer to measure relative pressure. A computing device can be connected to the strain gauge and the pressure transducers. The computing device executes programming instructions to identify failures of specific valves by correlating the strain signal to an actual pressure associated with the specific valve in the pump section. The processor then determines whether a pump pressure corresponds to the actual pressure associated with the specific valve, and if so, displays an indication that the specific valve in the pump section has failed.

    Abstract: A variable-capacity compressor that includes a housing having an inlet for receipt of refrigerant and an outlet for return of refrigerant, and a plurality of compressing elements contained in the housing between the inlet and the outlet. The variable capacity compressor includes a valve having an electrical control. The valve is dedicated to fewer than all of the compressing elements. The valve is movable between a first state which communicates refrigerant flow to the compressing elements, and a second state that reduces or stops flow to the compressing elements. In an embodiment of the invention, an unloading controller has an operational modulation mode that includes cycling the valve between on and off states to provide a portion of compressor capacity. The unloading controller is further programmed to provide a minimum delay time between transitions between the first and second states, but no maximum dwell time between transitions.
