Device for adjusting flow of circulating oil of sleeve oil pipeline

Abstract

The invention discloses a device for adjusting the amount of circulating oil of a sleeve oil pipeline. The sleeve oil pipeline comprises an oil return pipeline and an oil supply pipeline arranged in the oil return pipeline in a sleeved mode, and the end of the oil return pipeline and the end of the oil supply pipeline are respectively provided with an open port. The device comprises a cylindrical sleeve plug, one end of the sleeve plug is closed, and the other end of the sleeve plug is connected to the outer side of the port of the oil return pipeline in a plugging and sealing mode. An adjusting lead screw is transversely arranged at the center of the surface of the closed end of the sleeve plug in a penetrating mode, an adjustable plugging board right facing the port of the oil supply pipeline is connected to the inner end of the adjusting lead screw, and an adjusting handle is connected to the outer end of the adjusting lead screw. The device has the advantages that during circulating washing of the sleeve oil pipeline, the flow of the lubricating oil entering each branch pipeline can be adjusted, washing with a large flow many times a normal flow can be carried out on each branch pipeline of the sleeve oil pipeline to completely wash away residual impurities in each branch pipeline and guarantee the oil circulation effect, and therefore conditions are created for safe operation of a newly-assembled turbo generator unit.

Description

technical field [0001] The invention relates to a device for regulating the circulating oil volume of a set oil pipeline. Background technique [0002] Nowadays, the lubricating oil pipelines of large turbogenerators are mostly packaged oil pipelines. In order to ensure that the cleanliness of the lubricating oil entering the steam turbine bearing bush meets the requirements, the "extracorporeal circulation" of the packaged oil pipeline must be carried out after the packaged oil pipeline is installed when the new machine is installed. ", that is, the oil inlet pipe and oil return pipe of the lubricating oil are short-circuited outside the bearing seat of the steam turbine to carry out circular flushing of the set oil pipeline. The conventional flushing blocking plate only welds a blocking plate on the outside of the oil return casing, and does not adjust the amount of oil. Control, resulting in a large flow of lubricating oil near the lubricating oil pump, but the oil flow o...

[0002] Nowadays, most of the lubricating oil pipelines of large turbogenerators are packaged oil pipelines. In order to ensure that the cleanliness of the lubricating oil entering the steam turbine bearing bush meets the requirements, the "extracorporeal circulation" of the packaged oil pipelines must be carried out after the packaged oil pipelines are installed when the new machine is installed. ", that is, the oil inlet pipe and oil return pipe of the lubricating oil are short-circuited outside the bearing seat of the steam turbine to carry out circular flushing of the set oil pipeline. The conventional flushing blocking plate only welds a blocking plate on the outside of the oil return casing, and does not adjust the amount of oil. Control, resulting in a large lubricating oil flow near the lubricating oil pump, but the oil flow of the set oil pipeline far away from the lubricating oil pump is very small or even no oil flows through, resulting in poor oil circulation flushing effect, and the suit far away from the lubricating oil pump end It is not easy to clean the oil pipeline, if there are residual impurities in it, there is a great hidden danger to the safe operation of the turbo generator
