Valve Leakage Detection in Industrial Pumps
- Magazine Article
As an integral part of onshore and offshore drilling, mud pumps circulate drilling fluids to facilitate drilling oil and natural gas wells. Mud pumps stabilize pressure and support the well during the drilling process and drilling fluids provide friction reduction and a means to remove cuttings. A leak detection system for hex pumps was created for a hex mud pump with six pistons, six suction valves, and six discharge valves. The six pistons are driven by a rotating, asymmetric cam. The system monitors the suction and discharge valves using accelerometers.
