旋挖钻机夏日高温呈现的原因及处理办法

Causes and treatment of summer high temperature of rotary drilling rig

小型旋挖钻机是修建地基基础施工的重要机械，在房建、桥梁、地道、护坡等工程中起到不可代替的效果。旋挖钻机在运用过程中，随着时刻的推移，会呈现各式各样的问题。高温问题是咱们在修理中经常遇到的毛病现象，因其对机器性能及寿数影响比较大，扫除起来往往有一定难度，夏日高温问题给旋挖钻机用户带来了很大的烦恼和困惑。

Small rotary drilling rig is an important machine for foundation construction. It plays an indispensable role in housing construction, bridges, tunnels, slope protection and other projects. In the course of using the rotary drilling rig, with the passing of time, various problems will appear. The problem of high temperature is the common problem we often encounter in the repair. Because of its great influence on the machine performance and the number of life, it is often difficult to remove it. The summer heat problem has brought great trouble and confusion to the users of the rotary drilling rig.



呈现高温的原因

The cause of high temperature



旋挖机的高温一般分为分为齿轮箱(分动箱)温度过高;液压油温度过高;发动机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，首要原因有轴承或齿轮及壳体尺度形状不行标准、光滑油品不合格或油位不合适等。

The high temperature of rotary excavator is generally divided into gearbox (transfer box) temperature too high, hydraulic oil temperature too high, engine engine coolant temperature too high (commonly known as high water temperature). The reasons for the high temperature of the gearbox are relatively simple. The main reasons are that the size of the bearing or the gear and the shell is not standard, the smooth oil is not qualified or the oil level is not suitable.



发动机水温过高：焚烧正时禁绝、发动机功率缺乏、散热体系毛病都会引起发动机水温过高。在配共轨电喷柴油机曾经的发掘机上，因为液压油散热器安装在水箱冷却风的上游，因而液压油过热也会引起水温过高。

The engine's water temperature is too high: the incineration timing is prohibited, the engine power is deficient, and the cooling system defects will cause the engine water temperature to be too high. When the hydraulic oil radiator is installed in the upstream of the cooling wind of the water tank, the hydraulic oil overheating will also cause high water temperature in the former excavator of the common rail electric injection diesel engine.
