Rollers operating in high temperature environments: potential hazards and preventive measures

Jan 20th,2025 152 Views

In the hot summer, people can hardly go out. Why are mechanical equipment afraid of heat since it is not a living thing? Yes, small roller equipment is also afraid of high temperature. Excessive temperature will make small roller equipment difficult to use. The right temperature makes people feel good whether they are working or resting. It is not difficult to understand that small rollers also need a suitable temperature environment when working. If the equipment is used in an environment exceeding the working temperature, it will cause great damage to the equipment itself. In summer, due to the hot weather, the engine temperature is high, which is prone to failure, resulting in the engine not being able to dissipate heat normally and the power being reduced. Irregular maintenance of the engine will lead to a decrease in high-temperature operation and carbon deposits due to lack of oxygen in the lubricating oil. The accumulation of carbon deposits is prone to natural or deflagration failures of the engine.

Experiments show that for every 30°C environment above which the engine is exposed, the working temperature rises by 20°C, and the engine power will drop by about 3%. Small rollers often work in an environment of 50°C, indicating that the engine power will drop by about 4%. High temperature causes the viscosity of the lubricating oil to decrease, making it difficult to form a lubricating oil film, which reduces the lubrication effect. Under high temperature conditions, the anti-oxidation stability of lubricating oil drops sharply, which directly causes the deterioration of lubricating oil, causing the colloid and sediment of lubricating oil to adhere to the piston, cylinder wall and other parts surface, and the decline of thermal conductivity, which aggravates the wear of parts. The reduction of the working oil quality of the roller at high temperature is easy to cause external seepage and internal leakage, which reduces the efficiency of the hydraulic drive shaft system and makes the hydraulic drive shaft weak.

We have learned about the hazards of small rollers at high temperatures and how to prevent them. I hope it can help you.
