SENSOR FOR DETECTION OF OIL LEAKS AND OIL QUALITY IN STUFFING BOX OF WALKING BEAM PUMP SYSTEM

摘要

A method and apparatus for sensing unacceptable oil leaks from a stuffing box in a walking beam pumping system includes a container for receiving leakage from the stuffing box which is divided by a weir into a first compartment and a second compartment wherein the first compartment is provided with an adjustable outlet for setting the acceptable level of stuffing box leakage such that when the acceptable level is exceeded leakage into the second compartment occurs and is sensed by an appropriate sensor (28).
