AI Technical Summary

Problems solved by technology

In the same way, using larger pistons results in a larger and heavier drilling pump because adjacent pistons and cylinder liners must be spaced farther apart, i.e. increasing the center-to-center distance between the two cylinder liners, which also results in crankshaft and crankcase Higher loads, which requires increased crankshaft and crankcase strength - either by oversizing the crankshaft or increasing the thickness of the crankcase, or switching to a material with a higher yield strength, therefore increasing the center-to-center distance between the two cylinder blocks leading to drilling pump costs rise

Abstract

An assembly for mounting cylinder liners is provided, the assembly comprising a mounting structure comprising a base plate defining a hole and an internally threaded locating collar extending from the base plate around the hole, the base plate providing flange portions on opposite sides of the collar by which the mounting structure can be secured to a cylinder block; and a locating ring configured to be located around a cylinder liner and having an externally threaded end portion, whereby when the locating ring is positioned around an end portion of a cylinder liner and engaged with the threaded locating collar, the cylinder liner is secured to the mounting structure.

Description

technical field [0001] The invention relates to the field of oil and natural gas drilling equipment. In particular, it relates to a drilling pump cylinder casing assembly device. Background technique [0002] With the development of oil and gas exploration, the drilling depth gradually increases. This requires that the performance of the drilling pump, which represents the core of the drilling equipment, needs to be improved accordingly. For example, the drilling pump requires high drilling power, light weight and long operating life. The operating life of the drilling pump is related to the assembly quality of the drilling pump. Poor assembly quality will reduce the working life of the drilling pump or reduce the efficiency of drilling work. [0003] The drilling power is related to the displacement of the drilling pump, which depends on the size of the piston, the cross-sectional area of ​​the cylinder liner, the number of pistons and cylinder lines, and the average exp...
