Drilling mud equipment are various of types. Including the shale shaker, cleaner, centrifuge, degassers, and so on. Last post we talked about centrifugal pump, now what is relation between pump and mud equipment?
Hoppers, mud guns, desanders, desilters, degassers, and triplex pumps requiring supercharging all have one thing in common: they require a certain feet of inlet head to operate as designed. Exceptions do exist, and the equipment manufacturer should be consulted. This simplifies the job of sizing centrifugal pumps.
Since most applications in drilling systems require 80 feet of head at the inlet of the equipment, knowledge of volume needed by each piece of equipment is required. Following are theory standard flow rates when equipment has an 80-foot inlet head:
6-inch hopper with standard 2-inch nozzle: about 550 gpm
4-inch hopper with 1 1/2-inch nozzle: about 300 gpm
Mud gun with 3/4-inch nozzle: about 85 gpm per gun
Mud gun with 1-inch nozzle: 150 gpm per gun
Desander/desilter 4-inch cone: about 60 gpm per cone
Desander/desilter 10-inch cone: about 500 gpm per cone
Degasser: about 600 gpm
These are general standards. All values should be verified prior to sizing the centrifugal pump. Considering both suction and discharge conditions when sizing a centrifugal pump is very important.
