Big tile signs of fever and prevention of rotary kiln

Rotary kiln is big watts 2020 - signs of fever and prevention 11 - 22 Wang Zhanguang ( Jiaozuo strong cement) Rotary kiln big fever is more annoying things, sometimes a few watts fever at the same time, sometimes several fever in turn, affect the normal operation of equipment, to produce quality have a negative impact, if can be observed by certain signs, judgment may be fever, and take measures in advance, can reduce passive, reduce the loss. A, in several cases, watts may fever 1. Kiln caving serious skin caving in kiln, back to cause half half hot and cold rotary kiln cylinder is affected by temperature difference, thermal elongation of the more, the rather cold place less elongation, cylinder will bend, deviation from the center of the rotary kiln is not only the load fluctuation, also can cause belting leather produce disturbance, disturbance on the wheel to tile of belting leather, once a disturbance outside the spherical self-aligning ability, contact with the shaft will produce very big change, partial overload, inevitable fever will happen. 2. Rotary kiln temperature during heating up, if not normal operation during rotary kiln for various reasons failed to normal operation, and easy to normal cylinder bending, as easy as before the normal big fever. 3. A temporary halt to the kiln or fault kiln kiln temporary or fault pause, sometimes can't play slow turning kiln, can also cause cylinder bending, bearing caused by fever. 4. After cooling water cooling water, the heat in tile cannot be brought out in a timely manner, is bound to cause the oil temperature is high, so that the oil viscosity will fall and would reduce the bearing capacity, once the crushing, destruction of the oil film, shaft, direct contact with tile will increase the friction, cause a fever. 5. Bad lubrication bad lubrication has various forms, such as lack of oil, oil field and oil deterioration, such as oil pollution, the emergence of these adverse conditions, can cause the lubrication failure, one is to run the heat generated by the increased, second is the ability to take away heat to reduce, if the oil has a hard impurities, will also hurt, cause big fever. 6. Change oil film change oil film, or thin or uneven, or change the thrust plate of oil film, in the event of changes, means that the stress of the tile has change, is likely to cause a fever. 7. Environment changed environment change will make cooling conditions change, once destroyed the balance, easy fever, such as environmental temperature because of the weather, the influence of barrel temperature, ventilation, temperature rise, lubricating oil bearing capacity drops, once the oil film is destroyed or local damage, tile will be hot. 8. Foreign body into foreign body into the dust or granular material, would strain axis and tile, cause the loss of the contact accuracy or oil film damage, will cause a fever. 9. If the influence of the kiln kiln cylinder away from the rotary center, kiln is inevitable, but in the process of the kiln changed the original stress state, break the balance, it may cause of fever. Second, the rotary kiln fever fever prevention of rotary kiln watts for many reasons, this marks the prelude to prevent methods too much, can be summarized the following respects. 1. To the stability of coal and wind equipment, adjust good burner, lift the system stability, stable kiln, kiln cylinder rotary center in normal operation, avoid kiln bending disturbance. If that is the local kiln caving, should through the adjustment, the kiln skin patch as soon as possible, fill during kiln, should strengthen the tile guardianship, once appear, the oil film is unusual, but through the observation hole pour oil on the total shaft or proper reduction kiln speed made through fever crises. 2. Whether warming or stop kiln, Ann procedures, continuous slow turning kiln cylinder temperature is high, low temperature when the intermittent kiln; During long-term stop kiln, adhere to the timing of kiln turn, avoid kiln bending deformation. Once found rotary kiln axial uneven oil membrane process or local oil film disappear, will take measures to cylinder is sports school, such as continuous slow turning kiln, etc. , to prevent chafing bearing shell can pour oil measures, etc. 3. Any interruption or failure of other cooling measures, such as cooling water emergency rectification recovery, through measures such as spray oil during cooling, avoid long time heat imbalance, the four fever. If environmental conditions change is bigger, can use strengthen cooling fan. 4. When lubrication failure, such as insufficient oil level, oil deterioration or contamination, cloth oil failure, should be timely to fill, in the corresponding brand of lubricating oil, to modify oil scoop, cloth oil plate, can be reduced during kiln speed, complement other cooling measures. 5, foreign body into the block or grains of sand, can cause bearing shell strain, the four fever, if found to be the sand at this time, to observe hole in the gas and gradually released, out of the dust grains of sand, and if found to be the massive foreign body or metal foreign bodies, if can't pick, pick must stop kiln. 6, inspection found that the axial surface, thrust plate in the oil film changes, timely analysis of the reasons, such as kiln bending, poor lubrication and cooling water, into the foreign bodies, etc. , and take measures against reason. 7. The kiln is easy to cause the bearing shell fever, so more minor adjustment, changing the oil film (or larger, should take emergency measures, such as suspension tuning kiln or according to the circumstance again or refund less into a bit, can pour oil during strengthening cooling or help restore the oil film as soon as possible. Rotary kiln shell fever before the general reason, there is also a precursor, if can timely detection, timely measures, will greatly avoid the four fever, affect production, which requires careful inspection, timely measures to control. More than just the warning and prevention of some methods for bearing fever or views, wrong place, please readers to comment. （ Source: wisdom cement)
