Rotating-shaft-type main engine intelligent lubricating system and control method thereof

Abstract

The invention discloses a rotating-shaft-type main engine intelligent lubricating system and a control method thereof, and relates to the technical field of lubricating systems. The rotating-shaft-type main engine intelligent lubricating system and the control method thereof aim to solve the technical problem that a standby pump needs to be started manually in an existing lubricating oil system, and consequentially, intelligent operation of the whole lubricating system is inconvenient to realize. According to the key points of the technical scheme, the rotating-shaft-type main engine intelligent lubricating system comprises a unit, an oil supply pipeline, an oil tank, a main oil supply module, a standby oil supply module and a direct-current oil supply module, the main oil supply module, the standby oil supply module and the direct-current oil supply module are all arranged on the oil tank and connected to the oil supply pipeline, and the oil supply pipeline is connected to a to-be-lubricated position of the unit; and a control center, a liquid level control module, an oil temperature control module, a pressure control module, a high-pressure shaft jacking module, an energy-storagecontrol module, a cleanliness detecting module and a testing module which are matched and the corresponding control method are further included. The automation and intelligence effects of the lubricating system are improved.

Description

technical field [0001] The invention relates to the technical field of lubricating systems, in particular to an intelligent lubricating system and a control method for a rotating shaft main engine. Background technique [0002] A steam turbine is a rotary power machine that converts the energy of steam into mechanical work. The main power equipment of factories, metallurgical blower stations, etc., ensuring the safe and stable operation of steam turbines is a prerequisite for smooth production and maximum benefits. The role of the steam turbine lubricating oil system is to provide lubrication to the support bearings, thrust bearings and turning gear of the steam turbine, which is equivalent to the blood circulation system of the equipment. [0003] The existing Chinese patent with the publication number CN105545382A discloses a steam turbine lubrication system for thermal power generating units, which includes a main pump lubrication unit, which includes: a main pump connec...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the existing lubricating oil system needs to manually detect and judge the oil pump, and manually start the standby pump when the detected data is lower than the preset value, which is not convenient for realizing the intelligent operation of the entire lubrication system. Therefore, there is room for improvement
