Abstract

The invention relates to a steam turbine lubricating oil switching washing system and method. The steam turbine lubricating oil switching washing system comprises a bearing block, an oil washing device, an oil conveying pipeline communicated with the oil washing device, and an adjustable plug which is fixed at the end of the oil conveying pipeline and used for adjusting the lubricating oil flow in the pipeline, wherein the oil conveying pipeline includes an oil inlet main pipeline and an oil return main pipeline, the oil inlet of the oil inlet main pipeline is connected with the oil outlet of the oil washing device, the oil outlet of the oil return main pipeline is connected with the oil inlet of the oil washing device, the oil inlet of the bearing block is communicated with the oil inlet main pipeline through an oil inlet pipe, and the oil outlet of the bearing block is communicated with the oil return main pipeline through an oil return pipe. The steam turbine lubricating oil switching washing system has the advantages subsection washing is performed on the oil inlet pipe and the bearing block through the double-layer oil conveying pipeline, the lubricating oil can be cleaned during pipeline cleaning the bearing bush in the bearing block needs not to be demounted, convenience in washing is achieved, and washing lubricating time is saved.

Description

technical field [0001] The invention relates to the technical field of steam turbine lubricating oil flushing, in particular to a steam turbine lubricating oil switching flushing system and a flushing method thereof. Background technique [0002] The steam turbine is the core equipment of the thermal power plant. The function of the steam turbine lubricating oil system is mainly to provide lubrication for the supporting bearings, thrust bearings and turning gear of the steam turbine generator set and take away the heat generated by friction to ensure the safe and reliable operation of the unit. The lubricating oil system is mainly composed of the main oil pump driven by the main shaft of the steam turbine, oil cooler, jacking device, barring device, main oil tank, oil tank pipeline and accessories, lubricating oil pump, emergency oil pump, packaged oil pipeline, etc. In order to ensure the cleanliness of the oil system, the entire oil system needs to be flushed circularly. ...
