The hydraulic oil used in the mine loader is bright, light colored and transparent when observed in a clean mineral water bottle. Good hydraulic oil does not turn black or white, so what will cause it if it changes color?

1、新的礦用裝載機(jī)在設(shè)備磨合時(shí)會(huì)產(chǎn)生大量的鐵屑，不知你換油的時(shí)候是否將油箱中的液壓油全部清空，并用新油循環(huán)循環(huán)系統(tǒng)后，將油箱全部用棉布擦拭干凈后再加新油，如果沒有，就可能有大量鐵屑?xì)埩粼谟拖渲校矔?huì)導(dǎo)致新油被污染而發(fā)黑。

1. The new mining loader will produce a large amount of iron filings during equipment running in. I wonder if you empty all the hydraulic oil in the oil tank when changing the oil, and after using the new oil circulation system, wipe all the oil tank with cotton cloth and add new oil. If not, a large amount of iron filings may remain in the oil tank, which will also lead to the pollution and blackening of the new oil.

2、有可能是泵的高速旋轉(zhuǎn)而產(chǎn)生的磨屑，關(guān)于和泵旋轉(zhuǎn)的所有部件你都要考慮到，比如軸承、容積室等的磨損；

2. It may be the wear debris generated by the high-speed rotation of the pump. You should consider all parts rotating with the pump, such as the wear of bearings, volume chambers, etc;

3、檢查一下液壓系統(tǒng)是否封閉，呼吸孔是否完好；檢查設(shè)備液壓部分外露部件，看密封是否完好，比如油缸的防塵圈等。如果油品做顆粒度試驗(yàn)符合清潔度要求，可以排除是粉塵污染?？梢钥隙ǖ恼f是液壓油的溫度較高引起的。此時(shí)應(yīng)換用高品質(zhì)的液壓油，檢查回油濾芯，散熱油路，重要的是液壓油的散熱器，平時(shí)要按照規(guī)定保養(yǎng)維護(hù)。

3. Check whether the hydraulic system is closed and whether the breathing hole is intact; Check the exposed parts of the hydraulic part of the equipment to see whether the seal is intact, such as the dust ring of the oil cylinder. If the particle size test of the oil meets the cleanliness requirements, dust pollution can be eliminated. It is certain that it is caused by the high temperature of hydraulic oil. At this time, high-quality hydraulic oil should be replaced, and the oil return filter element and heat dissipation oil circuit should be checked. The important thing is the radiator of hydraulic oil, which should be maintained according to the regulations at ordinary times.

4、液壓系統(tǒng)黑油的不僅僅是有粉塵引起的，也是由于加注黃油不規(guī)范造成的。

4. Black oil in hydraulic system is not only caused by dust, but also caused by nonstandard filling of butter.
