Abstract
A high-power five-cylinder drilling pump set includes: a base, a drilling pump arranged on the base, and a lubricating system arranged on the base, wherein the drilling pump comprises a transmission assembly, a power end assembly and a hydraulic end assembly; the lubricating system comprises a power end lubricating system for lubricating and cooling the transmission assembly as well as the power end assembly, and a hydraulic end lubricating system for lubricating and cooling the hydraulic end assembly. According to the present invention, the high-power five-cylinder drilling pump set has a modular entire structure. In terms of the spatial layout, the present invention can effectively reduce the excessive size of conventional drilling pump or drilling pump structure. Based on the conventional structural design, the present invention simplifies the complex structure caused by intermediate mechanical speed change transmission mechanisms.
