Dynamic Balancing of Mud Pump Crankshafts
Last Updated on :30-January-2021
Mud Pump is one of the most critical equipment on the Rig; Powerful Mud Pumps pick up mud from the suction tank and circulate the mud down hole, out the bit and back to the surface.
In Rigs, two types of Mud Pumps are mostly used; namely, Triplex Pumps or Duplex Pumps, whereas Triplex Pumps have three pistons that move back-and-forth in liners. Duplex Pumps have two pistons move back and forth in liners.
Constant use of the Mud Pumps disturbs balancing of the Rotating components and the imbalance causes vibration, resulting in reduced Pump performance efficiency. To rectify such imbalanced Components and to retain the Pump performance efficiency, Dynamic Balancing is highly recommended.
We provide Dynamic Balancing Services to meet each and every Customers’ requirement.
We have installed SCHENCK Machines which ensure that Balancing Jobs are done in a precise and accurate manner.
