高温环境下压路机的操作说明
来源：/ 日期：2022-05-13
现在正值炎热的季节，气温高，雨多，空气潮湿，给机械施工带来了很多困难。租用压路机在该项目中工作的时候，高温会使冷却系统散热困难，发动机容易过热。发动机温度高时，容易产生爆燃，使发动机工作不顺，降低功率。
Now it is a hot season, with high temperature, much rain and humid air, which has brought many difficulties to mechanical construction. When the leased roller works in this project, the high temperature will make it difficult for the cooling system to dissipate heat, and the engine is easy to overheat. When the engine temperature is high, it is easy to produce deflagration, so that the engine does not work smoothly and the power is reduced.
实验表明，当发动机超过30℃时，工作温度每升高20℃，发动机功率就会下降3%左右。小型压路机经常在50°C的环境下工作，这意味着发动机功率降低约4%。高温使润滑油粘度降低，不易形成润滑油膜，降低润滑效果。
The experimental results show that when the engine temperature exceeds 30 ℃, the engine power will decrease by about 3% for every 20 ℃ increase in the working temperature. Small rollers often operate at 50 ° C, which means that the engine power is reduced by about 4%. High temperature reduces the viscosity of lubricating oil, which is not easy to form lubricating oil film and reduce the lubrication effect.
在高温条件下，润滑油的抗氧化安定性急剧下降，直接导致润滑油变质，使润滑油的胶体和沉淀物附着在活塞、缸壁等部位表面，导热系数下降，加剧了润滑油的劣化。磨损在组件上。
Under the condition of high temperature, the antioxidant stability of lubricating oil decreases sharply, which directly leads to the deterioration of lubricating oil, so that the colloid and sediment of lubricating oil adhere to the surface of piston, cylinder wall and other parts, and the thermal conductivity decreases, aggravating the deterioration of lubricating oil. Wear on components.
高温下压路机工作油质的降低容易造成外渗和内漏，从而降低液压传动轴系统的率，使液压传动轴变弱。
The reduction of the working oil quality of the roller under high temperature is easy to cause external leakage and internal leakage, so as to reduce the efficiency of the hydraulic transmission shaft system and weaken the hydraulic transmission shaft.
滚筒发动机过热的关键是加强冷却系统的维护和保养。经常检查并拉紧风扇皮带，及时清理散热器上的积尘，加强散热器的通风。对于水冷发动机，也可用与冷却系统正常循环相反的方向用水冲洗散热器和水套。
The key to overheating of drum engine is to strengthen the maintenance of cooling system. Frequently check and tighten the fan belt, timely clean the dust on the radiator and strengthen the ventilation of the radiator. For water-cooled engines, the radiator and water jacket can also be flushed with water in the direction opposite to the normal cycle of the cooling system.
在此提醒，非工作车辆不要暴晒。滚筒冷却。这个非常重要。我们知道压路机的外壳是充满油的，在夏天是非常危险的，而且轮胎暴晒后容易爆胎。为确保车辆，请勿将机器暴露在阳光下。
Please be reminded not to expose non working vehicles to the sun. Drum cooling. This is very important. We know that the shell of the roller is full of oil, which is very dangerous in summer, and the tire is easy to burst after exposure to the sun. To ensure the safety of the vehicle, do not expose the machine to the sun.
压路机一般工作的地方比较空旷，夏天没有阴凉的地方，但是这样长期暴露在外面的阳光下，对车辆本身是非常不利的，会缩短车辆的使用寿命。济南压路机租赁厂家提醒大家，压路机在高温环境下工作时要注意对压路机的保养，及时做好防护措施。
Generally, the working place of the roller is relatively open, and there is no shady place in summer, but such long-term exposure to the outside sun is very unfavorable to the vehicle itself and will shorten the service life of the vehicle. Jinan roller rental manufacturer reminds you that when the roller works in a high temperature environment, you should pay attention to the maintenance of the roller and take protective measures in time.
That's all for the operation instructions of road roller in high temperature environment. If you need the equipment, please follow our website at Com for more information.
