Progressive cavity pump system having reverse mode

A progressive cavity pump (PCP) system includes a PCP with a rotor rotatably disposed in a stator, a permanent magnet motor, sucker rod(s), and a control system. The rotor is coupled to one of the sucker rods via a high-torque connection that allows for counter clockwise rotation without loosening the connection between the rotor and sucker rod. The control system operates the system in a production mode by rotating the rotor clockwise. Upon manual input by a user, or automatic triggering when protections settings of the control system call for a shutdown or cleanout or when the control system senses an imminent pump shutdown, the control system operates the system in a reverse mode by rotating the rotor counterclockwise. The reverse mode pumps fluids and suspended solid particles down into the well prior to pump shutdown to inhibit the solids from clogging the pump or preventing the pump from restarting.

Fuel delivery system with pressure-controlled electric pump

A fuel delivery system which includes a fuel pump and a dc motor, which are preferably contained within a unitary housing. A pressure-sensitive switch, which is either contained within the unitary pump/motor housing or as a separate structure, includes a movable contact positioned within a housing so as to form a first chamber for receiving fuel under pressure and a second chamber for venting to atmosphere. A spring urges the movable contact against a second contact for applying electrical power to the pump motor.

HYDRAULIC ENGINE WITH PARKING BRAKE

Pump control device for hydraulic working machine, pump control method, and construction machine

A pump control device for a hydraulic working machine has a rotation speed setting device for setting a target rotation speed of an engine, a rotation speed control device for controlling the speed of the engine to the target rotation speed, a first variable hydraulic pump for driving a hydraulic actuator for work and driven by the engine, a second variable hydraulic pump driven by the engine and used to drive a cooling fan, and a pump control device for controlling the discharge flow rate of the first variable hydraulic pump and that of the second variable hydraulic pump in order that the sum of suction torque of the first variable hydraulic pump and suction torque of the second variable hydraulic pump does not exceed engine output torque predetermined according to the target rotation speed. The pump control device (a) controls the discharge flow rate of the second variable hydraulic pump based on the target rotation speed and on a target discharge flow rate of the second variable hydraulic pump and (b) limits and controls suction torque of the first variable hydraulic pump by calculating suction torque of the second variable hydraulic pump and deducting the suction torque of the second variable hydraulic pump from engine output torque predetermined according to the target rotation speed.
