The Management of the Wind Power Lubrication System Looks Forward to Transformation
The wind turbine
is a large high-precision, high-value operating equipment, with all bearings,
gears and other parts in frequent start-and-stop, high load, and continuous
operating conditions. Wind power plants are mostly concentrated in remote areas
with tremendous wind resources, such as mountains, wilderness, beaches, and
islands, etc., which can cause serious damage to the equipment with poor
natural environment. Besides, the equipment is high and it is inconvenient to
maintain. So, it puts forward higher and stricter requirements for equipment
service and maintenance.
Good wind power
lubrication systems are of great importance to extend the service life of wind
turbine transmission parts, lower operation and maintenance costs, guarantee
the normal operation of wind turbine generators, and improve economic benefit.
With continuous improvement of the quality requirements of wind turbine
generators, the lubrication system will certainly become an important subject
in the field of wind power and gets innovated and developed constantly.
Zhao Daping,
Chairman of AUTOL, said that the variable propeller and yaw part in wind fields
in China now generally adopts the lubrication methods combining spring-piston
pump casings and increment type distributors and that many problems existed in
the actual application process. First, the “timing and quantitative”
lubrication method of traditional lubrication system cannot meet the requirement
difference for every part of the wind turbine generators, thus causing poor
lubrication in some parts and over lubrication in some other parts. Second,
most of the wind field environment in China is harsh, and the auxiliary
pressure oil technology of the spring pressure-oil pan adopted in the
lubrication pump in the market has limited effects, so that depletion and stall
of the lubrication pump usually occurs in low-pressure or cold environment, so
as not to guarantee valid lubrication for parts of the wind turbine. Besides,
increment type distributors generally used in the traditional lubrication
system are limited by the structure, so that blockage may occur, directly
causing invalid lubrication for other lubrication parts.
AUTOL has been
actively promoting enterprises to conduct lubrication health management,
devoted to setting up systematic standard thinking, and formulate a relevant
lubrication management system and technical standards, so that the enterprise
can conduct justifiable lubrication management. Besides, AUTOL evaluates the
lubrication effect and gradually develops and improves industry-recognized
lubrication management systems for wind power equipment.
