在裝載機制動液的使用方面，應(yīng)該合理存放和使用，避免其吸水受潮而影響制動性能；山東裝載機每作業(yè)600—800h更換1次制動液，普通環(huán)境下每作業(yè)800—1000h更換1次制動液；在更換制動液時，必須將原有制動液排放干凈，并使用新的合格制動液對制動管路進行沖洗，能夠增長機器的使用壽命。

1、良好的粘溫性能和低溫性能
礦用裝載機經(jīng)常工作在山地和礦山等惡劣工作環(huán)境中,所以裝載機的工作方式要求裝載機每個工作循環(huán)中頻繁前進和倒退,制動摩擦片長時間處于制動狀態(tài),所以制動過程中,由于摩擦發(fā)熱可使摩擦片溫度高達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、為了保持制動缸和橡皮碗能很好地滑動,要求制動液有適當(dāng)?shù)臐櫥浴?br /> In order to maintain the brake cylinder and the blanket bowl slides well, require proper brake fluid lubrication.
3、保證制動安全可靠不產(chǎn)生氣阻
在山東裝載機行駛時經(jīng)常制動而產(chǎn)生大量的摩擦熱,使制動系統(tǒng)溫度升高,如使用沸點低、易于蒸發(fā)的制動液,則在高溫時會由于制動液的蒸發(fā),使局部制動系統(tǒng)的管道內(nèi)充滿蒸氣，產(chǎn)生氣阻，引起制動失靈。因此要求制動液應(yīng)具有較高的沸點,較低的蒸發(fā)性,以避免減少氣阻的產(chǎn)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、較好的防腐蝕性
制動液應(yīng)對制動器各種金屬零部件有較好的防腐蝕性。
Brake fluid brake response to a variety of metal parts have better corrosion resistance.
5、良好的化學(xué)安定性
制動液長期在高濕作用下使用,因此要求制動液不產(chǎn)生熱分解和重合,而使油品增粘,也不允許生成油泥沉積物。
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、良好的與橡膠的適應(yīng)性
在制動系統(tǒng)中有許多橡膠密封件與皮碗等,用以保持制動系統(tǒng)完全密閉,因此制動液應(yīng)具有良好的與橡膠密封的適應(yīng)性,防止橡膠密封件與皮碗因油液不相容而膨脹、機械強度降低.
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.
