Fan gear box oil change skills

Fan gear box oil change skills - 2018 12 - 01 gear box is one of the most core components of the wind turbines. In order to ensure the high-efficiency and stable operation of the fan, must ensure that the lubrication performance of the gear box. Therefore, gear lubrication management especially the gearbox oil change work to become an important task of wind operators can not be ignored. Implement scientific and rigorous oil change procedures: gear box used lubricating oil is composed of many different types of base oil and additives. The typical oil could be mineral oil or synthetic oil, they may be compatible with each other. Therefore, the compatibility of lubricating oil must be determined before an oil change. If compatible, belong to low risk in oil, general 'emissions' and' charging 'can, but if the system residual oil by more than 3% of old shun yi added to' wash 'process; If not compatible, belong to high risk in oil, suitable beneficial Suggestions to rinse the gearbox, from gear box used oil, reduce the pollution of the new oil, so as to realize the excellent performance and long service life of the new oil, to ensure the efficient operation of the fan. In circulation flushing oil at the same time, still need to pay special attention to oil filter clogging problem, to ensure the oil change process smoothly. Fan gear box oil change program generally includes' emissions', 'wash' and 'insert'. Using the appropriate oil change program to ensure lubricating performance and normal operation of the equipment itself, optimization of gear lubrication performance, extended oil change cycle and filter replacement cycle, improve the productivity of the life of the gear box and fan. In the process of full practice, summarizes the following procedures: 1. Determine the new oil compatibility with previous lubricating oil. Consult technical engineer team for assistance. 2. Discharge of oil to the gear box system, drainage net as much as possible. 3. Point move oil circulation pump motor at low speed until all the oil in the pipeline has been pumping out, and at the first time I heard the pump cavitation noise stopped operation. 4. From the oil pump disconnect all external pipe and the pipe emissions. Discharge any remaining oil in oil cooler. 5. All of the sediments and debris to clean oil filter shell. Replace all removable filter ( Use the filter equipment manufacturers recommended) 。 Reconnect all external pipeline. 6. Open the gear box inspection cover and find previously filling lubricating oil residue. If there are any conditions, take photographs to record state. 7. If in step 1 of lubricating oil is regarded as incompatible, and the purity of the observed in step 6 is acceptable, please directly to step 13. 8. To the gear box filling oil circulating the required minimum level of flushing oil ( Final inject new oil) 。 60% of the proportion is usually filled with oil. Please consult the equipment and technical personnel to establish the minimum capacity required for oil circulation. 9. Choose multi-speed high-speed level circulation flushing oil pump. Make the turbine operation or needle wheel operation. Loop 2 to 4 hours, or until the oil temperature of 60 ℃ / 140 & deg; F。 10. In the process to monitor whether the oil filter clogging. If oil filter clogging are observed, according to the need to replace oil filter, and each time cleaning filter shell. Circulating oil until oil filter is no longer blocked. Then, close the oil pump and stop the rotor. 11. The discharge of oil. Open the gear box inspection cover and check the oil residue. And pointed out that the capacity of the comparison in step 6. 12. Repeat steps 8 - according to need 11 in order to achieve an acceptable level of clean. 13. Give a new oil filling system, the use of installed oil filter equipment * in order to realize the target oil cleanliness grade ( - recommend ISO4406 standards / 14/11) 。 Adopt the advanced technology in oil equipment: 'fan oil change is inevitable in the wind field operations of work, is one of the keys to the wind field and stable operation. Relying on traditional artificial oil change is not only the intensity of labor is big, maintenance personnel risk is high, and artificial oil change caused by the fan in a long time to stop the opportunity to raise oil cost; Traditional oil change, on the other hand, can make the old oil in the gear box can't completely clear, new oil cleanliness not guaranteed, and affect the service life of gear box and filters. 'China agricultural machinery industry association, wind power equipment branch secretary general Mr Qi and raw oil change problem when it comes to fan said,' how to safe and efficient to complete the oil change program is a huge challenge in front of the wind operators. 'in order to solve oil change problem wind operators: safety in replacing human back oil pipeline, the oil to the gear box is located in high altitude, emissions, such as cleaning, washing and filling process, reduce maintenance personnel security hidden danger; Environmental protection effectively remove old oil and pollution and clean the gear box, improve the efficiency of the use of lubricating oil, reduce oil waste, optimize the oil consumption and reduce the impact on the environment. High efficiency fan oil change oil truck mechanization in the time it takes less than half of the traditional oil change time, can make the fan to recover faster, reduce outage losses. During the fan operation, to provide a series of comprehensive product testing, monitoring, lubricating oil and the condition of the equipment as soon as possible send including oil contamination or metal abrasive dust, the early warning signal, make the maintenance personnel in a timely manner to take action to remove hidden dangers or decision whether need to replace lubricating oil, help enterprise to optimize the lubrication management and use, extend the service life of lubricating oil. At the same time, with the professional knowledge of lubrication, to help enterprises solve various problems encountered in the process of oil change, the scene to guide the scientific and efficient oil change. Wind power as a national vigorously promote and rely on renewable energy industry, must want to rely on leading technology, to ensure safety, environmental protection and efficient production.
