The simple treatment method for the heating of the rotary kiln support wheel was carried out in the production operation of the Haolianghe Cement Co., Ltd. 4153 in Heilongjiang Province, and the temperature of the No. 6 roller was increased rapidly. After 201, it was raised to 100, and the material was slowly turned to the cold kiln. The inspection found that the oil film of the No. 6 roller axle was not formed well, and there were strips of dry white on the shaft surface of the roller, and there was a slight copper hanging phenomenon. After the temperature of the cylinder body was lowered, we stopped the kiln to open the upper end cover of the No. 6 roller axle, and measured the contact angle between the lower roller axle and the bearing bush with the feeler gauge. The oil discharge groove of the bearing bush was within the normal range, and the auxiliary facilities were not abnormal. . We decided not to stop the kiln to re-scrape the bearing bush. In the case of normal operation of the rotary kiln, the roller axle and the bearing bush run in. The kiln is normally fed, and the top wire of the No. 6 roller base is adjusted outwards, so that the No. 6 roller reduces the force. The grease made of the lead oil in the No. 6 roller is applied to the surface of the roller axle. The roller axle and the bearing bush are run-in, and the circulating water is cooled, and the roller shaft is swayed up and down, commonly known as the lava, and is observed while being worn. In the place where there is a dry white strip on the roller axle, continue to apply the grease until the dry convex strip on the roller shaft disappears, and the entire axle surface of the roller is grayish white so that the roller axle and the bearing bush are ground. Then release the circulating water and add the lubricating oil until the oil film of the wheel axle is formed. The support roller can work normally. After normal operation, the oil film of the No. 6 roller axle is also formed well and the temperature is normal. This method does not need to stop the kiln, it is simple and effective, and it works well. After the running time, replace the roller lubricant.
Elk 1觞 oil station æ¶ said the basket road improvement Hao Libin Heilongjiang Province Mudanjiang New Material Technology Co., Ltd. 157041 Our company No. 1 kiln main reducer model is 2,63006, using forced lubrication, the used thin oil station The model number is 1, 20, the original lubrication line 1.
After the shutdown of the thin oil station, the friction pairs in the reducer were analyzed, and we improved the lubrication pipeline.
The improved method can realize the free conversion of the lubrication mode of the reducer, that is, the conversion of forced lubrication and splash lubrication. In the event of a failure at the lubrication station or in the winter, the forced lubrication method can be changed to the splash lubrication mode by adjusting the valve of the pipeline without affecting the operation of the main engine. Furthermore, it is solved that the cold oil pipeline and the cooling water pipeline need to be insulated in winter. When the ambient temperature is high or the oil needs to be filtered, the lubrication method can be converted into a forced lubrication method. The specific method of switching from forced lubrication to flying irrigation is to close the valve 2 and open the valve 1. At this time, the fuel pump does not stop. When the lubrication station is found, check whether the oil level of the reducer reaches the height required for splash lubrication.
