旋挖钻机在使用过程中,随着时间的推移,会出现各种各样的问题。高温引起的故障是维修中经常遇到的故障现象,给旋挖钻机用户带来了很大的烦恼和困惑,其对机器性能及寿命影响比较大,排除起来往往有一定难度。旋挖钻机的高温一般分为齿轮箱(分动箱)温度过高、液压油温度过高、发动机冷却液温度过高(俗称水温高)。齿轮箱温度过高的原因相对单纯,主要原因有轴承或齿轮及壳体尺寸形状不够标准、润滑油品不合格或油位不合适等。本文 Rotary drilling rig in use, with the passage of time, there will be a variety of problems. Faults caused by high temperature are often encountered in the maintenance of the phenomenon of failure, rotary drilling rig users to bring a lot of trouble and confusion, its impact on the performance and life of the machine is relatively large, often have some difficulty in the exclusion. Rotary drilling rig high temperature is generally divided into gearbox (transfer case) temperature is too high, the hydraulic oil temperature is too high, the engine coolant temperature is too high (commonly known as high water temperature). The reason why the temperature of the gearbox is too high is relatively simple. The main reason is that the size and shape of the bearing or the gear and the shell are not enough, the lubricant is unqualified or the oil level is not suitable. This article
