Embodiment Construction

[0015] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings. The invention discloses a semi-external oil circulation system of a steam turbine generator set oil pipeline, which comprises a main engine oil tank, an engine oil delivery part connected with the main engine oil tank, and a lubricating part connected with the engine oil delivery part. The lubricating part includes the lubricating oil inlet pipe, the parts to be lubricated connected with the lubricating oil inlet pipe, the lubricating oil return main pipe connected to the lubricating parts, and the lubricating oil return main pipe connected to the oil tank of the main engine. The oil delivery part includes 4 temporary oil passages for oil delivery and a large-flow flushing device. The large-flow flushing device is connected to the main engine oil tank through the emergency oil discharge pipeline. Temporary oil passage for oil delivery I is ...

Abstract

A turbine generator set oil pipeline half-outside oil circulation system comprises a main engine oil tank, an engine oil conveying part connected with the main engine oil tank, and a lubricating part connected with the engine oil conveying part; the lubricating part comprises a lubricating oil inlet pipe, components to be lubricated and a lubricating oil return mother pipe, wherein the components to be lubricated are connected with the lubricating oil inlet pipe, the lubricating oil return mother pipe is connected with the components to be lubricated, and the lubricating oil return mother pipe is connected with the main engine oil tank; the engine oil conveying part comprises four temporary engine oil conveying oil circuits and a high-flow flushing device. The turbine generator set oil pipeline half-outside oil circulation system has the advantages that the high-flow flushing device is used in the system flow unified distribution state, the flushing mode of paralleling operation of a pumping set of the system and a high-flow pumping set can be realized, and the requirement of a lubricating oil system for high-flow flushing is well met.

Description

technical field [0001] The invention relates to the technical field of steam turbine generators, in particular to a semi-external oil circulation system for circulating and flushing pipelines of lubricating oil systems of newly built and overhauled steam turbine generator sets before starting. Background technique [0002] The role of the steam turbine lubricating oil system is to provide lubrication to the support bearings, thrust bearings and barring devices of the turbogenerator, to supply oil to the spare pipe of the hydrogen sealing system, and to supply oil to the overspeed release device of the operating machinery. [0003] In order to prevent fire caused by the leakage of the pressure oil pipeline, the oil supply pipe from the main oil tank to the main oil pump, the pressure oil pipe at the outlet of the main oil pump, the pressure oil pipe supplying oil to the security system, the pressure oil supply to each bearing, jacking shaft, and cranking The oil pipe, the spa...
