液压油温过高：首要原因是产热过快和散热过慢。液压泵进油管路及液压油箱密封不严、进油滤芯阻塞、液压体系管路不畅通、液压泵内部泄漏都会使液压油发生很多热量然后使液压油温度因产热过而快速升高。液压油散热器内部通道有阻塞、散热器外部灰尘过大、风力不行、液压油未经过液压油散热器等原因可导致液压油因散热过慢而高温。

Hydraulic oil temperature is too high: the main reason is too fast heat production and too slow heat dissipation. The seal of the hydraulic pump and the hydraulic oil tank is not strict, the oil filter core is blocked, the hydraulic system pipeline is not smooth and the internal leakage of the hydraulic pump will make the hydraulic oil have a lot of heat and then make the hydraulic oil temperature rise rapidly because of the heat production. The internal channel of the hydraulic oil radiator is blocked, the external dust of the radiator is too large, the wind is not good, the hydraulic oil does not pass through the hydraulic oil radiator and so on, which can cause the high temperature of the hydraulic oil to be too slow because of the slow heat dissipation.



怎样有用防止高温现象的发生呢？机器呈现高温问题可经过以下几个方面去防止或处理：

How can it be useful to prevent the occurrence of high temperature phenomena? The high temperature problems of machines can be prevented or dealt with in the following ways:



1、有些机主为了省钱直接用水作为水箱的冷却液，这些水箱在运用一段时刻后会结出水垢，然后影响整个散热体系的散热才能然后发生高温，所以整理水箱的水垢可认为设备降温。铲除水箱水垢的办法首要是选用化学办法，即经过酸性或碱性物质与水垢效果，使水垢转化成可溶于水的物质而被铲除。在选用酸或碱溶液时，应考虑水垢的性质、铲除水垢的效果，以及对清洗件是否有腐蚀效果等要素。为防止水垢的发生主张运用专业的冷却液。

1, some owners in order to save money directly to use water as the cooling liquid of the water tank, these tanks will be formed after a period of time, and then affect the whole heat dissipation system to heat the heat and then have high temperature, so the scale of the water tank can be considered to cool the equipment. The first way to remove the scale of the water tank is to choose the chemical method, that is, through the acid or alkaline material and the effect of scale, it can be removed to the substance that can be dissolved in water. When using acid or alkali solution, we should consider the nature of scale, the effect of scaling, and whether there are corrosive effects on cleaning parts. In order to prevent the occurrence of scale, it is advocated to use professional coolant.

2、清洗液压油散热器、滤网，水散热器叶片、滤网，用高压水或压缩空气吹去水箱散热片上的杂物。

2, wash the hydraulic oil radiator, filter screen, water radiator blade, filter screen, and use high pressure water or compressed air to remove the sundries on the radiator.

3、替换冷却液，先把机子停放在平坦的当地，待发动机冷却后翻开散热器盖，然后拧开散热器总成底部的排水阀把原冷却液放掉，之后用水清洗水箱，封闭排水阀，较终加注新的冷却液。

3. Replace the coolant. First, the machine is parked in the flat area. After the engine is cooled, the radiator cover is opened, then the drain valve at the bottom of the radiator assembly is unscrewed off the original coolant, then the water tank is washed, the drain valve is closed, and the new coolant is finally added.

4、别的，能够装个淋水罐。电动的临水体系，需要手动的按钮。装轿车淋水体系的都会，自己动手也很简单。水温高的话翻开几分钟就降下来了,水箱较好能装在不显眼的当地。不失漂亮，并且会很有用。

4, other, can be equipped with a spray tank. The electric front water system requires manual buttons. It is also easy to install a car dripping system. If the water temperature is high, it will come down in a few minutes, and the water tank is best placed in an inconspicuous place. No loss of beauty, and it will be useful.

5、平常多留意清洁，呈现高温报警现象后，查看是不是水箱外面的滤网被堵住了？假如堵住就整理一下，没事拿水枪冲冲。较终提示假如作业环境的水质欠好的话就劲量不要加水了，尽量挑选加防冻液，防止发掘机高温现象呈现。

5, usually pay more attention to cleanliness, showing a high temperature alarm phenomenon, check whether the filter outside the water tank is blocked up. If it's blocked, clean up. There's nothing to rush with a water gun. Finally, if the water quality of the working environment is not good enough, do not add water to the energizer. Try to choose antifreeze solution to prevent the phenomenon of high temperature in the excavator.
