Lubrication and cooling mechanism of a pipeline pump bearing assembly

Abstract

The invention belongs to the technical field of pump parts and particularly relates to a lubricating and cooling mechanism for pipeline pump bearing components. The lubricating and cooling mechanism comprises a rotary shaft, more than one group of the bearing components are arranged on the rotary shaft at intervals, a bearing body is arranged outside the bearing components, an oil sump is formed on the bearing body, and an oil slinger is mounted on the rotary shaft in a sleeved manner and droops into the oil sump. A fan is arranged, so that temperature of the outer surface of the bearing body can be lowered to a large extent, and fairly significant heat radiating effect of a whole bearing mechanism is realized; friction coefficient of a slide bearing is small, so that a machine can rotate flexibly and briskly, working efficiency is improved, consumption of lubricating oil is small, mounting and demounting are convenient, the slide bearing is reliable in working, stable and free of noise, and a lubricating oil layer has vibration absorbing capacity and can bear big impact load; and the oil slinger and an oil flinger realize lubricating and cooling effects, so that the lubricating oil in a whole oil chamber is circulated well, and effects of bearing lubricating and lubricating oil cooling are realized.

Description

Technical field: [0001] The invention belongs to the technical field of pump components, in particular to a lubricating and cooling mechanism for a pipeline pump bearing assembly. Background technique: [0002] The bearing assembly is an indispensable part of the pipeline pump. The bearing is used to support the rotor parts and bear various loads acting on the rotor parts. According to the structural characteristics and performance parameters of the designed pump. It is one of the main components that affect the normal operation of the pump. Therefore, the working performance of the bearing assembly directly affects the operation of the overall pump. The bearing assembly generates heat during work, which needs to be dissipated in a timely manner, resulting in a short service life of the bearing assembly, resulting in short maintenance periods and high cost of use in pipeline pumps. Improvement to extend the overall maintenance cycle of the pipeline pump and improve the st...
