装载机制动液有哪些使用要求？

在装载机制动液的使用方面，应该合理存放和使用，避免其吸水受潮而影响制动性能；山东装载机每作业600—800h更换1次制动液，普通环境下每作业800—1000h更换1次制动液；在更换制动液时，必须将原有制动液排放干净，并使用新的合格制动液对制动管路进行冲洗，能够增长机器的使用寿命。

1、良好的粘温性能和低温性能
矿用装载机经常工作在山地和矿山等恶劣工作环境中,所以装载机的工作方式要求装载机每个工作循环中频繁前进和倒退,制动摩擦片长时间处于制动状态,所以制动过程中,由于摩擦发热可使摩擦片温度高达250℃。
Mine Loader often work in the mountains and mines and other harsh working environment, so the loader loader work requires frequent each working cycle forward and reverse, brake lining a long time in the braking state, so the braking process , due to frictional heating at temperatures up to make the friction plate 250 ℃.
2、为了保持制动缸和橡皮碗能很好地滑动,要求制动液有适当的润滑性。
In order to maintain the brake cylinder and the blanket bowl slides well, require proper brake fluid lubrication.
3、保证制动安全可靠不产生气阻
在山东装载机行驶时经常制动而产生大量的摩擦热,使制动系统温度升高,如使用沸点低、易于蒸发的制动液,则在高温时会由于制动液的蒸发,使局部制动系统的管道内充满蒸气，产生气阻，引起制动失灵。因此要求制动液应具有较高的沸点,较低的蒸发性,以避免减少气阻的产生。
When the brake is often Shandong loader with a large amount of frictional heat generated by the brake system, the temperature rises, such as the use of low boiling point of brake fluid which tend to evaporate, the evaporation at a high temperature due to brake fluid, so that the local full steam pipe brake system, air resistance, causing Zhidongshiling. Thus requiring the brake fluid should have a high boiling point, low volatility to avoid the generation of reducing air resistance.
4、较好的防腐蚀性
制动液应对制动器各种金属零部件有较好的防腐蚀性。
Brake fluid brake response to a variety of metal parts have better corrosion resistance.
5、良好的化学安定性
制动液长期在高湿作用下使用,因此要求制动液不产生热分解和重合,而使油品增粘,也不允许生成油泥沉积物。
Brake fluid using a long time under the effect of humidity, thus requiring the brake fluid does not generate heat decomposition and overlap, leaving oil thickening, sludge deposits is not allowed to generate.
6、良好的与橡胶的适应性
在制动系统中有许多橡胶密封件与皮碗等,用以保持制动系统完全密闭,因此制动液应具有良好的与橡胶密封的适应性,防止橡胶密封件与皮碗因油液不相容而膨胀、机械强度降低.
There are many other rubber seals and sleeves in the brake system, the system is completely sealed to maintain the braking, the brake fluid should therefore have a good adaptability to the rubber seal to prevent the rubber cups for the oil seal and is not expanded compatibility, mechanical strength is lowered.
