Ensure effective lubrication of the wind power gear box

Ensure wind effective lubrication of the gear box - 2020 12 - 30 MiaoShiLi Huang Wei ( Sinopec lubricant co. , LTD. ) 1 the importance of lubrication wind turbines after put into operation, its operation is stable, is one of the most concern problems of wind power enterprise, but also the fundamental factors determines wind farm profitability. Among them, the fan running lubrication protection is essential. Lubrication is in relative to the surface of the friction between lubricant to form antifriction layer, reduce the friction factor, reduce friction, reduce power consumption, reduce friction heat production. Lubrication mechanism of the gear drive is to make the lubricant, the surface of the meshing gear lubrication film formation force meshing tooth surfaces apart, will dry friction into lubricant internal meshing gear tooth surface of internal friction between the molecules. Good lubrication can ensure normal operation within the temperature range of required. 2 fan operation condition and effective demand for lubrication lubrication can reduce friction, wear, and take away the heat generated by the between meshing tooth surfaces, avoid high temperature caused by gluing etc. The occurrence of tooth surface damage; Prevent rust, isolated from the air, and so on; At the same time can reduce the vibration and noise; Take away of abrasive and impurities on the surface of the tooth. Selection of 3 gear oil according to the national standard oil released on March 9, 2017, October 1, 2017 the implementation of the special wind turbine lubricant national standards ( GB / T 33540) ( Contains bearing grease, open gear grease, transmission gear oil, hydraulic oil, four parts] The index requirements of gear oil, wind turbine gearbox gear oil ( Synthetic) Technical requirements and experimental method, as follows: according to gear manufacturers recommend product selection of lubricant brand: according to equipment manufacturers recommendations. Such as: the Flemish product certification is well-known industrial gear oil industry certification test, the certification audit by the German management, review once every five years. Flemish will through a series of certification test of lubricating oil brand to join the list, recommend or for customers to choose. Major domestic fan gear box manufacturers: chongqing gearbox factory, nanjing high speed gear box factory to determine oil change cycle, such as wear conditions of a focus on equipment, reduce the risk of equipment used. Oil analysis has two purposes, one is the workpiece quality detection by lubrication, 2 it is to detect the quality of lubricating oil. Due to relatively games of the friction pair of parts wear, wear and lubricating oil is the direct performance will contain a lot of wear particles. According to the above reasons, it is recommended that periodic inspection of lubricating oil, the main project, experiment method and the abnormal cause analysis is as follows: other indicators: cleanliness, flash point, pour point, anti-foam index is also a measure of the fan gear oil can be selectively according to wind field and oil monitoring and attention. 4 grease storage and management guarantee the oil cleanness, avoid foreign material to enter after adding oil, sealing barrel mouth and properly handle in time, keep the oil barrel for clean, avoid foreign matter wear particles into the lubricating oil, etc. Dry seal open oil easy to enter the water, keep dry, indoor save as far as possible, avoid water, oil emulsion. Have equipment in oil identification, avoid make wrong oil phenomenon lubrication small CARDS ( Sheet steel/plastic packaging paper CARDS) Refueling, paste in key equipment, and remind staff pay attention to.
