This is a recipe for disaster. The research is based on one of the most common types of pumps used on drillships (and land-based drilling rigs), triplex 14-P-220 mud pump made by NOV. Over-pressurization is a looming factor that can cause significant damage to drills and machinery, making quality drilling pop-off valves a must. As a rule, wear analysis leads to an observation that one type of wear was a primary cause of damage, the other are secondary consequences [4, 6].
To confirm the importance of the issue, we have analysed the number of failures associated with mud pumps on one of the deep-water drilling rigs over the past three years. There are no reliable criteria for the assessment of mud pump condition. Lockout the pump before working on it!
Drilling Mud Pumps For Sale
It should be close to the pump discharge, properly sized and drained after every job. Drilling mud pumps for sale. Crown Block Guide In Oil & Gas Rigs. Depending on the drilling fluid base liquid (usually oil or water), the components of mud pump sustain wear at a varying rate. CrossRef][Green Version]. If for some reason too much pressure builds up in the discharge line, perhaps the drill bit or annulus gets plugged, the relief valve opens.
In this paper, faults of the pump valve module are identified by means of acoustic emission (AE) signals. Innovative unibody valve design eliminates snap rings, plates or keepers providing. In this article, a possibility of the…. However, it may be a consequence of previous abrasive wear, occurring when solid particles from the mud (e. Mud Pump In Oilfield Rigs Parts, Types & Calculations. g., sand) got into areas of friction. It should be borne in mind that the pressure in the valve module reaches 515 bar. These valves prevent too high a pressure from being built up in the circulating system. This method has been verified by experiments conducted on a NOV (National Oilwell Varco) -made triplex 14-P-220 mud pump (mounted in the drillship).
Wear and tear, and the tribological processes in friction nodes can therefore cause changes in the characteristic frequencies of the process itself. Traveling Block Application & Inspection. Additionally, we also add the full detailed transcripts which will acceleate the learning curve of learners. Drilling rig mud pump valve and seats. Like in typical phenomena related to elastic wave propagation, the waves from other sources (farther from the sensor) will attenuate by themselves. AE signal source from the running pump valves, with indicated stages of valve operation. Be sure that the shear relief valve is set to release at a pressure not exceeding working pressure of the pump, valves and mud lines. In a classical case, in terms of physics, acoustic emission is a phenomenon of spontaneous generation of elastic waves by regrouping the internal structure of solids (seldom liquids) and physical systems. Energies2020, 13, 1138.
