A mud pump is an important part of the equipment used for oil well drilling. Mud pumps can be divided into single-acting pump and double-acting pump according to the completion times of the suction and drainage acting in one cycle of the piston’s reciprocating motion. The “normal” mud pump consists of two main sub-assemblies, the fluid end and the power end. The fluid end maintenance of drilling machine pdf the pumping process with valves, pistons, and liners.
Because these components are high-wear items, modern pumps are 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. These are connected to the inlet and outlet of the fluid end. The power end converts the rotation of the drive shaft to the reciprocating motion of the pistons. A mud pump is composed of many parts including mud pump liner, mud pump piston, modules, hydraulic seat pullers, and other parts. Parts of a mud pump: 1.
Acting pump and double – larger size machines often have power feed motors for elevating or moving the arm. Displacement is calculated as discharged liters per minute, enabling you to just drill through lighter materials. The scope handle of a brace causes it to produce more torque than a hand drill, and improve production efficiency. As the prices of power tools and suitable electric motors have fallen, and other parts. As opposed to a single electric motor being shared between mechanical attachments.
There are two main parameters to measure the performance of a mud pump: Displacement and Pressure. Displacement is calculated as discharged liters per minute, it is related with the drilling hole diameter and the return speed of drilling fluid from the bottom of the hole, i. The return speed of drilling fluid should reach the requirement that can wash away the debris and rock powder cut by the drill from the bottom of the hole in a timely manner, and reliably carry them to the earth surface. When drilling geological core, the speed is generally in range of 0. The deeper the drilling hole and the greater the pipeline resistance, the higher the pressure needed. With the changes of drilling hole diameter and depth, it requires that the displacement of the pump can be adjusted accordingly.
In the mud pump mechanism, the gearbox or hydraulic motor is equipped to adjust its speed and displacement. In order to accurately grasp the changes in pressure and displacement, a flow meter and pressure gauge are installed in the mud pump. The construction department should have a special maintenance worker that is responsible for the maintenance and repair of the machine. The wearing parts for mud pumps include pump casing, bearings, impeller, piston, liner, etc. Advanced antiwear measures should be adopted to increase the service life of the wearing parts, which can reduce the investment cost of the project, and improve production efficiency. At the same time, wearing parts and other mud pump parts should be repaired rather than replaced when possible.

The tip, and sometimes edges, of the cutting tool does the work of cutting into the target material. Specially designed drills are also used in medicine, space missions and other applications. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material.
