Mistakes in the use and maintenance of tyres

1. Random increase the locomotive load The locomotive's trailer has a rated load. If the long-term overloaded load exceeds the design tolerance of the tire, it will often cause tire wear. 2. When shifting, starting, or braking excessively when the locomotive is in operation, if shifting or starting too much, not only will the deformation of the carcass be aggravated, but it will also cause severe friction between the tread and the ground, especially in uneven conditions. Or there are spikes, stones, bricks and other road surface is more obvious; locomotive brakes too often, the locomotive will often slide, so that the tire and the ground sliding friction, accelerate tire wear. 3. Long-term sun, wind, rain Some drivers in the off-season operations, are often free to put the locomotive open air, so long-term sun, wind, rain, can cause tire aging deterioration, shorten its life . Therefore, when locomotives are stored for a long time, they should be placed in a dry, cool, dark room and the fuselage should be raised to prevent permanent deformation and aging of the tires. 4. Use sharp, sharp tools to disassemble and disassemble tires. If sharp and sharp tools are used to damage the inner and outer tires, care must be taken to remove dirt, solids, and hard objects. Into the tire to prevent puncture, corrosion tires. 5. Do not avoid oils, alkalis, acids, etc. Contact with diesel oil, engine oil, grease and other oil substances and acids, strong alkaline substances, have a strong corrosive force on rubber tires, so do not let these substances contact the tires, Always use water to clean the dirt on the tires and keep the tires clean. 6. Locomotives can easily scratch the treadle when the locomotive is running on a road surface with spikes, sharp bricks, glass and other sharp objects. Therefore, we should try our best to avoid letting the locomotive run on it. We must avoid slowing down and preventing scratches and injuries. 7. Freely increase and reduce the weight of iron In general, when the tractor is working in a field with heavy loads such as cultivating and rotating tillage, weighted iron is installed on the rim of the tire to reduce tire slip; when the tractor is long-term In order to reduce rolling resistance during transportation operations, the weight can be reduced, not only reducing tire wear, but also improving the operational efficiency. Therefore, you cannot increase or decrease the weight. 8. If the inflation of the pneumatic tire is not in accordance with the regulations, the cushioning force of the tire will be weakened, the vibration of the locomotive will intensify, and the irregular pressure of the tire will be increased. When a large impact is encountered, the inner tube may even be detonated; if the tire pressure is too low, the pressure will be too low. The deformation of the tire is too large, the rolling resistance is increased, the tire is prone to heat aging, and the service life is shortened. Therefore, the tire must be inflated as required. 9. The locomotive curve climbing uphill in this way not only increases the walking distance of the locomotive, and affects the normal driving route of the incoming and outgoing vehicles. It is also prone to drop and collision accidents on the ramp, and it also accelerates the steering mechanism and the front Tire wear. 10. Not strictly controlling the tire temperature When the locomotive runs long distance or when driving in hot summer, the temperature of the tire will continuously increase, which will reduce the mechanical properties of the tire material, increase the wear, and easily cause the rip of the cord and the loose breakage of the cord. Therefore, the temperature of the tire must be strictly controlled during the running of the locomotive, and the temperature of the tire should not exceed 90°C to prolong the service life of the tire. 11. Locating the front wheel of the locomotive incorrectly If the front wheel of the locomotive has a large camber and the front wheel is too large, it will accelerate the wear of the front tire. Therefore, it is necessary to check, repair and adjust in time to ensure that the front wheels of the locomotive are positioned correctly.
