ABSTRACT:
A progressing cavity well pump has an overspeed brake to protect the gear box during reverse rotation. A power source rotates an input shaft of the gear box, which through a right angle drive, drives a string of rods extending into the well to the progressing cavity pump. A centrifugal brake is mounted to the input shaft. If the pump locks up, the power source will impart energy to the rods by twisting them until the power source reaches its limit. When the rods start to unwind, the centrifugal brake will engage to dissipate energy and slow the speed of the reverse rotation.
