Regular maintenance can make devices to keep the best of the state, and to extend fan life. Regular repair and maintenance work of the main elements are: fan couplings between the bolt torque inspection (including electrical connections), the lubrication between the transmission components and various functional tests.
Fan in normal operation, each connected component of the Bolt to run in a variety of vibration of long-term effort which is very easy to loose, so in order not to loose bolts after the cause of local Shouli Bu were cut, we must regularly Bolt torque check of their conduct. In the environmental temperature is lower than -5 ℃, should make it down to the rated torque for tightening torque of 80, and after the temperature is higher than -5 ℃ review. We generally check on the fastening bolts are arranged in non-small air or wind in summer, to avoid the high power fan season.
Fans of the lubrication system mainly dilute oil lubrication (or lubrication of mineral oil) and dry oil lubricating wind turbines (or grease lubrication) in two ways. Fan gear boxes and yaw Gear Box uses a thin lubricating methods, the maintenance is of additional testing and sampling, if the test results show that the lubricant can no longer use, then wind power generator replaced. Generator parts are dry lubricated bearings, yaw bearing, yaw gear and so on. These components run as high temperature, highly degenerate, resulting in bearing wear and tear, regular maintenance must be carried out each time up to its increase. In addition, the generator bearings according to additional doses of a certain number of requests to join, not too much, to prevent too many to squeeze into the motor windings after, the motor burned out.
Regular maintenance of functional testing test key too quickly, emergency shutdown test, hydraulic system component value test, vibration test switch, twisted cable switch test. You can also set limits on the controller, some routine test values. In addition to regular maintenance other than the above three items, but also check the hydraulic oil level, small wind turbines the sensor for damage, the sensor’s power supply is reliable work, brake pads and brake disc wear and so on.
