The composition structure and working process of the centralized lubrication system of wind turbines
The production and assembly process of the core components of the centralized lubrication system, such as pump cores, distributors, oilers, and control systems, involves advanced manufacturing technologies such as monitoring of important parameters and leak testing using the differential pressure method. The centralized lubrication system produced has the characteristics of high component matching accuracy, high output pressure of the electric lubrication pump, good system sealing, and monitorable system oil discharge status. The design and production threshold of the centralized lubrication system is relatively high, requiring close cooperation between a research and development team with a solid theoretical foundation and a production team with rich production experience.
The centralized lubrication system is generally composed of four basic parts: a lubrication pump, a distributor, a pipeline assembly, and a control system. Its working mode is to supply lubricating grease to one or more lubrication points in the mechanical equipment in a timely and quantitative manner from a lubricating grease supply source through oil metering parts and some distributor distribution pipelines, which can largely meet the lubrication needs of important components of the mechanical equipment, such as engine bearings, variable pitch bearings, yaw bearings, etc., and reduce the friction loss generated during operation. The centralized lubrication system is a type of hydraulic system in terms of its product structure and operating principle. It can achieve automatic, multi-point precision lubrication. Through the reasonable design of the centralized lubrication system structure, it can automatically add lubricating grease to the lubrication points required by mechanical equipment in a timely and quantitative manner, avoiding the shortcomings of low precision, uneven grease distribution, and high risk of use in extreme environments caused by manual addition of lubricating grease to mechanical equipment. It is a product of modern industrial development.
