An oil return system for circulating oil lubricated bearings of rotating machinery

Abstract

The invention discloses an oil returning system of a rotating machinery circulation oil lubricating bearing. The oil returning system comprises an oil returning pump, an oil returning pump mounting bracket, a connection shaft, an oil returning pipeline, a buffering oil tank, a reversing valve and an oil tank, wherein the oil returning pump mounting bracket is mounted on a rotating machinery base; the oil returning pump is mounted on the oil returning pump mounting bracket; the oil returning pump is connected with the connection shaft by a shaft coupler; the connection shaft is connected with a rotary shaft of rotating machinery; an oil inlet of the buffering oil tank is connected with an oil returning hole of a bearing by the oil returning pipeline; an oil outlet of the buffering oil tank is connected with an oil inlet hole of the reversing valve; two oil outlet holes of the reversing valve are connected with an oil inlet and an oil outlet of the oil returning pump respectively; an oil returning hole of the reversing valve is connected with the oil tank. The oil returning system of the rotating machinery circulation oil lubricating bearing is simple and compact in structure and convenient to mount; the oil returning system is applicable to working conditions that that a pipe arrangement space is limited, the oil amount of circulation oil is greater or oil returning pipe arrangement cannot meet gravity oil returning requirements, and the problem that the oil is leaked from a bearing seal, caused by the fact that the oil returning is not smooth is prevented.

Description

technical field [0001] The invention relates to an oil return system for circulating oil lubricated bearings of rotating machinery. Background technique [0002] With the development of society, various high-power rotating equipment develops rapidly. On the one hand, it can improve the efficiency of energy utilization, and on the other hand, it can save relative space. However, with the development of high-power rotating equipment, the amount of oil required for bearing lubrication is also increasing, resulting in the problem of poor return of bearing lubricating oil. Especially for equipment with relatively strict space restrictions, such as marine equipment and other occasions where the space requirements are relatively strict and the amount of lubricating oil in the bearings is large It is difficult to meet the requirements of the gravity oil return of the bearing. This design uses the power of the rotating machine itself to realize the oil return function of the circula...
