在裝載機(jī)制動(dòng)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(dòng)性能；山東裝載機(jī)每作業(yè)600—800h更換1次制動(dòng)液，普通環(huán)境下每作業(yè)800—1000h更換1次制動(dòng)液；在更換制動(dòng)液時(shí)，必須將原有制動(dòng)液排放干凈，并使用新的合格制動(dòng)液對(duì)制動(dòng)管路進(jìn)行沖洗，能夠增長(zhǎng)機(jī)器的使用壽命。

1、良好的粘溫性能和低溫性能
礦用裝載機(jī)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(jī)的工作方式要求裝載機(jī)每個(gè)工作循環(huán)中頻繁前進(jìn)和倒退,制動(dòng)摩擦片長(zhǎng)時(shí)間處于制動(dòng)狀態(tài),所以制動(dòng)過程中,由于摩擦發(fā)熱可使摩擦片溫度高達(dá)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(dòng)缸和橡皮碗能很好地滑動(dòng),要求制動(dòng)液有適當(dāng)?shù)臐?rùn)滑性。
In order to maintain the brake cylinder and the blanket bowl slides well, require proper brake fluid lubrication.
3、保證制動(dòng)安全可靠不產(chǎn)生氣阻
在山東裝載機(jī)行駛時(shí)經(jīng)常制動(dòng)而產(chǎn)生大量的摩擦熱,使制動(dòng)系統(tǒng)溫度升高,如使用沸點(diǎn)低、易于蒸發(fā)的制動(dòng)液,則在高溫時(shí)會(huì)由于制動(dòng)液的蒸發(fā),使局部制動(dòng)系統(tǒng)的管道內(nèi)充滿蒸氣，產(chǎn)生氣阻，引起制動(dòng)失靈。因此要求制動(dòng)液應(yīng)具有較高的沸點(diǎn),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(dòng)液應(yīng)對(duì)制動(dòng)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(dòng)液長(zhǎng)期在高濕作用下使用,因此要求制動(dòng)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(dòng)系統(tǒng)中有許多橡膠密封件與皮碗等,用以保持制動(dòng)系統(tǒng)完全密閉,因此制動(dòng)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(jī)械強(qiáng)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.
