Bailer pumps for oil wells

Abstract

Abstract A bailer pump designed for securing to a well head comprising an elongated stan pipe projecting upward from the well head supporting a motor driving a reel for cable through a drive train incorporating a magnetic brake, when the current to the motor is interrupted the magnetic brake is activated. A bailer is propelled into and out of the well in a repititious controlled manner. The electrical control mechanisms operate in conjunction with a pivot arm mounted at the top of the stan pipe on an axle. Pillow blocks retain the pivot arm in a tilting position. Tension or lack of tension on the cable passing over the top pulley causes a reciprocal tilting of the pivot arm and the pulley. The tilting arm contacts a micro switch which through time delay and relays start, stop, and reverse the electric motor operating the cable reel. The short delay in the well permits filling of the bailer and a long delay at the well head permits unloading of the bailer. The long delay is energized by the bailer striking a bailer stop contacting the top micro switch stopping the motor and activating the long delay. The unloading function is accomplished mechanically by the bailer contacting the bailer stop pulling an actuating rod which through a trough linkage tilts the unloading trough under the bailer striking a dart at the bottom of the bailer emptying the contents of the bailer into an oil receiver.
