泥漿泵是在鉆井過程中，向鉆井輸送泥漿或水等介質的機械。

　　Mud in the drilling process, the drilling mud or water transport machinery such as washing fluid.

　　泥漿泵是鉆探機械設備的重要組成部分。

　　Mud drilling machinery and equipment is an important part.

　　它的主要作用是在鉆進過程中將泥漿隨鉆頭鉆進注入井下，起著冷卻鉆頭，清洗鉆具、固著井壁、驅動鉆進，并將打鉆后巖屑帶回地面的作用。

　　Its main role is in the drilling mud during the process of drilling with the drill bit into the hole, play a bit cool, clean drilling, fixation wall, drive drilling, and drilling cuttings back to the ground after the role.

　　在常用的正循環(huán)鉆探中﹐泥漿泵是將地表沖洗介質─清水﹑泥漿或聚合物沖洗液在一定的壓力下﹐經(jīng)過高壓軟管﹑水龍頭及鉆桿柱中心孔直送鉆頭的底端﹐以達到冷卻鉆頭﹑將切削下來的巖屑清除并輸送到地表的目的。

　　In the commonly used positive cycle of drilling, the mud pump is to rinse the surface with water medium ─ ﹑ mud or polymer washing fluid at a certain pressure, through the high-pressure hose taps and drill column ﹑ center hole in the bottom of the direct-drill in order to achieve Cooling ﹑ be cutting down the drill cuttings removal and transport to the surface purpose.

　　常用的　泥漿泵是活塞式或柱塞式的﹐由動力機帶動泵的曲軸回轉﹐曲軸通過十字頭再帶動活塞或柱塞在泵缸中做往復運動。在吸入和排出閥的交替作用下﹐實現(xiàn)壓送與循環(huán)沖洗液的目的。

　　Mud is a common type or plunger-type piston, driven by the motive power of the crankshaft rotary pump, crankshaft driven through the crosshead and then the plunger in the pump cylinder piston or reciprocating motion to do. In the alternating suction and discharge valve under the influence of pressure delivery and recycling to achieve the purpose of washing fluid.
