Lubricating oil system of power generator

Abstract

The invention discloses a lubricating oil system of a power generator. The lubricating oil system comprises two circulating pipelines, namely a first circulating pipeline and a second circulating pipeline as well as a lubricating oil tank, a main oil pump, an oil cooler, a jacking oil pump, an emergency oil pump, a filter, a pressure meter, a thermometer and valves, wherein the first circulating pipeline comprises a plurality of branch pipelines and a primary pipeline; the main oil pump and the oil cooler sequentially communicate with one branch pipeline; the emergency oil pump and the oil cooler separately communicate with the other branch pipeline; the filter, the pressure meter, the thermometer and the plurality of valves are arranged on the primary pipeline; and the jacking oil pump, the filter, the pressure meter, the thermometer and the plurality of valves are arranged on the second circulating pipeline in a communication mode. The lubricating oil system of the power generator provided by the invention can effectively implement lubricating protection on a bearing of the power generator, is more remarkable in lubricating effect, and is higher in reliability and safety.

Description

technical field [0001] The invention relates to the technical field of generator equipment, in particular to a generator lubricating oil system. Background technique [0002] The generator lubricating oil system is a system equipment used to cool and lubricate the bearing bush of the generator. In specific applications, a large amount of heat is generated between the generator shaft and the bearing pad during high-speed operation. If lubrication and cooling are not performed in time, the bearing pad will overheat, causing the bearing pad to burn out and the generator shaft to wear. [0003] For the generator, in addition to the lubrication system, there is also a jacking shaft oil circuit, and the jacking shaft is filled with oil during the starting process of the generator to reduce the starting torque and facilitate starting. Lubricating oil and jacking oil come from the same oil tank. In the lubricating oil system, the lubricating oil needs to be pressurized, filtered a...

Problems solved by technology

[0004] However, the generator lubricating oil system of the prior art still has some objective technical defects: namely, the generator lubricating system in the prior art has technical defects such as lack of a cooling device to achieve cooling, impurities are easily mixed into the oil tank, and poor lubrication effect; Therefore, the reliability of the generator lubrication system in the prior art is poor, and its reliability and safety performance need to be further improved.
