Description

Technical Field

[0001] This utility model relates to the field of mud pump technology, specifically a pump casing for a mud pump. Background Technology

[0002] A mud pump is a machine used to deliver mud or water, or other flushing fluid, into the borehole during drilling. Mud pumps are an important component of drilling equipment. In commonly used positive circulation drilling, they deliver the surface flushing medium—clean water, mud, or polymer flushing fluid—under certain pressure through a high-pressure hose, swivel, and the center hole of the drill string directly to the bottom of the drill bit. This cools the drill bit and removes and transports the cut rock cuttings to the surface. Common mud pumps are piston or plunger type, driven by a power unit that rotates the pump's crankshaft. The crankshaft, through a crosshead, drives the piston or plunger to reciprocate within the pump cylinder. The alternating action of the suction and discharge valves achieves the purpose of pressurizing and circulating the flushing fluid.

[0003] Existing patent CN206957914U discloses a pump housing for a mud pump. This utility model includes a housing, a connecting box, and a motor base. One side of the housing has a boss for positioning and connecting with a gearbox, and the boss has multiple threaded connection holes. The connecting box is a closed structure, connected to the housing via double-ended studs and a connecting box positioning pin. The connecting box serves as a transition connection between the housing and the power end. The motor base is mounted on top of the housing and has a set screw plate for adjusting the motor position. The motor base is fixedly connected to the housing. This utility model has a simple structure, shortens the transmission chain, greatly improves transmission efficiency, is easy to process and assemble, is small in size and light in weight, and meets the installation requirements of new mud pumps.

[0004] However, although the existing patent CN206957914U has a simple structure, can shorten the transmission chain, greatly improve the transmission efficiency, is easy to process and assemble, is small in size and light in weight, and can meet the installation requirements of new mud pumps, at the connection between the pump casing and the discharge pipe, mud leakage is easily caused by the impact pressure when the mud is discharged.
