It is one functional part of the rig and the key equipment in the drilling fluid circulating system. Mud pump is designed to transmit the fluid with high viscosity, high density and high sand content under high pressure to cool the bit and carry the rock debris out from the well bottom. The drilling fluid can also supply power to the drilling tool in the bottom of the well and play an additional role in the drilling of the bit. The following three kinds of mud pump are available with different sizes and specifications: 1) Triplex Mud Pump It is applicable to drilling operation which requires high pump pressure, such as oil drilling. It works by reducing the volume of the working fluid to produce sufficient pressure. It includes three pistons. The middle piston exerts bigger pressure to the crankshaft and the other two external pistons exert smaller pressures. However, the excessive pressure caused by high piston load results in cracking or failure of the crankshaft of the pump. 2) Duplex Mud Pump It is used to ensure the circulation of drilling mud or liquid supply from the mud cleaning system to the bottom of the well. It can use diesel or electricity as power source. It is easy to be maintained as it incorporates a new design of safety valve and has binocular floating seals of piston rods. In addition, It is equipped with a system of forced lubrication of piston rods to reduce friction that normally causes quick wear and tear. 3) Quintuplex Mud Pump It is used to pump fluid in drilling process. It has a continuous duty return piston. The external bearings in the quintuplex mud pump are designed to support the crankshaft. The pump produces a lot of noise and dust, which interferes with measurements while drilling. The modifications for the pump is difficult because of.its complicated design.
