wind turbine gearbox lubrication system

Product Overview

Suplub-W system is  the new intelligent wind turbine centralized lubrication solution that integrates computer, automation, wireless data communication and centralized lubrication technology. It consists of intelligent monitor unit, grease supply unit and waste oil recovery unit. Wireless remote control center can be installed in wind farm headquarters for monitoring the working condition of all lubrication systems.

Applications
Automatically  lubricate the main bearing, yaw bearing, pitch bearing,  generator bearing of the wind turbine generator. 

Working Principles 
The working process of the Suplub-W lubrication system contains three steps:

Step I: When the pause interval ends, the intelligent controller firstly sends start signal, and then the high-pressure lubrication pump starts and the grease is conveyed to the main grease line. When the grease pressure reaches the setting value, the intelligent controller successively opens the points that need grease, and the grease is injected to the points after accurately measuring according to the needs.

Step II: After all the points are lubricated, the intelligent controller sends waste grease recovery signal, and the waste grease suction & draining device starts to recover the waste grease.

Step III: After the waste grease recovery finishes, the intelligent controller sends stop signal to each actuator, the high-pressure lubrication pump stops and the lubrication system enters the next pause period.
