A wind turbine and its centralized lubrication system

Abstract

The invention relates to a wind generator and its centralized lubrication system. The wind turbine includes a lubrication system for filling each bearing of the wind turbine with grease and a grease replenishing system for replenishing the oil tank with grease. The fat-replenishing system includes a fat-replenishing room. The fat-replenishing room is equipped with a fat-replenishing machine, a fat-replenishing table, a transfer barrel, a product oil barrel and multiple oil tanks. The grease outlet on the oil suction tray is connected to the grease filling table through the grease filling pipe. The grease filling table is inlaid with a quick-plug female connector. The quick-plug female connector is connected with the grease filling pipe. The lower part of the barrel has a grease filling channel, the lower part of the grease filling channel is equipped with a quick-plug male joint, and the lower part of the fuel tank has a lower convex oil port, and the lower convex oil port is sealed and inserted in the upper part of the grease filling channel to communicate with the quick-plug male joint. The female connector is inserted and matched with the quick-plug male connector. It has the advantages of convenience, quickness, low cost, safety and reliability of fat supplementation.

Description

technical field [0001] The invention relates to a wind generator and its centralized lubrication system. Background technique [0002] The wind turbine includes a wind wheel and a generator; the wind wheel contains blades, hubs, reinforcements, etc. The wind power source is composed of a wind turbine, a tower supporting the generator, a battery charge controller, an inverter, an unloader, a grid-connected controller, and a battery pack. The yaw, pitch and main shaft bearings of wind turbines are the core transmission components of the wind turbine, and their lubrication directly determines the life and operating efficiency of the wind turbine. If the fan bearing is poorly lubricated, it will lead to increased bearing wear and heat generation, which may lead to bearing failure or even fire. [0003] Therefore, in the maintenance of wind turbines, the lubrication of each friction pair becomes the top priority. Traditional fan lubrication is mostly manual, that is, manually ...

AI Technical Summary

Problems solved by technology

But different from car refueling, since the lubricating pump is fixed on the fan, you can only carry the grease supply equipment to climb up the fan for tens of meters to replenish the grease on site. This process of climbing the fan with the equipment and the grease bucket is very inconvenient

[0006] On the other hand, after climbing onto the fan with heavy equipment, since the lubricating grease has a viscous structure of semi-solid and semi-liquid, its fluidity is extremely poor. In the process of entering the oil tank of the lubricating pump, the resistance is extremely high. In addition, the oil tank of the lubricating pump is equipped with a spring piston structure, which makes the process of pushing the piston upward to compress the spring more laborious, and further increases the resistance of filling. Therefore, The entire fat replenishment process takes a long time, which not only increases the working time of the maintenance personnel on the fan, but more importantly, reduces the time for the fan to generate electricity, which causes great trouble to customers

[0007] Furthermore, the finished oil barrels used by the shuttle of this centralized lubrication system may still have leftovers after use. These open half barrels of grease are easy to enter dust and impurities during the process of handling and storage. If it enters the lubrication pump and distributor of the centralized lubrication system, the plunger pair of the lubrication pump and distributor will be blocked, which will cause the centralized lubrication system to fail and stop, so that the friction pairs of the fan cannot be lubricated normally, thus Cause subsequent bearing wear, heat and even fire
