Mud plunger pump (also known as mud plunger pump) is a core equipment used in petroleum drilling, geological exploration, mining and other fields to transport high viscosity and high solid content mud. Its working principle is based on volumetric reciprocating motion, which changes the pump chamber volume through the periodic reciprocating motion of the plunger, realizing the suction, pressurization and discharge of mud. The following provides a detailed analysis from four dimensions: core principles, key components, work cycle, and special design adaptability:

　　The essence of a mud plunger pump is a reciprocating volumetric pump, and the core logic is to use the "reciprocating motion of the plunger in the pump cylinder" to change the volume of the pump chamber (the enclosed space formed by the plunger and the pump cylinder):

　　When the volume of the pump chamber increases, the pressure inside the chamber is lower than the pressure in the suction pipeline, and the mud is "sucked" into the pump chamber under the pressure difference;

　　When the volume of the pump chamber decreases, the pressure inside the chamber is higher than the pressure in the discharge pipeline, and the mud is "squeezed" and transported downstream through the discharge pipeline (such as drilling wellbore, conveying pipeline).

　　The entire process relies on a chain reaction of "volume change → pressure difference → fluid flow", and due to the precise coordination of the plunger and pump cylinder, it can achieve high pressure (up to 30MPa or more) and stable flow transportation, adapting to the special physical characteristics of mud (containing sand and clay particles, viscosity usually 50~1000mPa · s).
