Title:
HIGH-POWER FIVE-CYLINDER DRILLING PUMP SET, SOLID CONTROL SYSTEM, AND DRILLING RIG
Document Type and Number:
WIPO Patent Application WO/2023/273330
Kind Code:
A1
Abstract:
Disclosed are a high-power five-cylinder drilling pump set, a solid control system, and a drilling rig. The drilling pump set comprises a base (4), wherein the base is provided with a drilling pump and a lubrication system; the drilling pump comprises a transmission assembly (1), a power end assembly (2) and a hydraulic end assembly (3); and the lubrication system comprises a power end lubrication system (5) for lubricating and cooling the transmission assembly and the power end assembly, and a hydraulic end lubrication system (6) for lubricating and cooling the hydraulic end assembly. By means of the high-power five-cylinder drilling pump set, modularization in the design of the overall structure is achieved, the problem of the large structure of a traditional drilling pump or drilling pump set can be effectively solved in the spatial arrangement of the structure, and the problem of a complex structure caused by intermediate mechanical variable-speed transmission mechanisms such as a belt transmission and a chain transmission is solved, thereby effectively achieving the optimization effect of the overall structure.
