Mud Pump Structure

Mud Pump Structure

A mud pump is a reciprocating piston/plungerdevice designed to circulate drilling fluid underhigh pressure (up to 7,500 psi (52,000 kPa) ) down the drill string andback up the annulus.

Mud pump is a large reciprocating pump used to circulate the mud (drillingfluid) on a drilling rig. It is an important part of the oil well drillingequipment.

Classification

According to the acting type

Mud Pumps can be divided into single-acting pump anddouble-acting pump according to the completion times of the suction anddrainage acting in one cycle of the piston's reciprocating motion.

 

Composition

The"normal" Mud Pump consists of two main sub-assemblies, the fluid endand the power end.

 

Fluid End

The fluid end produces the pumping process with valves,pistons, and liners. Because these components are high-wear items, modern pumpsare designed to allow quick replacement of these parts..

 

To reduce severe vibration caused by the pumping process,these pumps incorporate both a suction and discharge pulsation dampener. Theseare connected to the inlet and outlet of the fluid end.

 

Power End

The power end converts the rotation of the drive shaft tothe reciprocating motion of the pistons. In most cases a crosshead crankgear is used for this.
