當(dāng)升降貨梯液壓系統(tǒng)長期進(jìn)行運(yùn)作的時(shí)候，會(huì)發(fā)現(xiàn)液壓油溫度會(huì)不斷地升高，但是操作人員常常會(huì)對這個(gè)問題進(jìn)行忽視而繼續(xù)進(jìn)行操作，則會(huì)讓機(jī)械無法正常進(jìn)行運(yùn)作。下面濟(jì)南榮凱升降機(jī)械的有關(guān)專家就給大家介紹一下液壓油溫度過高的危害。
1、升降貨梯液壓油溫度過高會(huì)導(dǎo)致液壓油的黏度會(huì)下降，從而影響到液壓系統(tǒng)的工作效率，增加液壓油泄漏的幾率，甚至還會(huì)讓設(shè)備無法再進(jìn)行正常的工作。
lift hydraulic oil temperature is too high will cause the viscosity of the hydraulic oil will decline, thus affecting the efficiency of the hydraulic system, increase the risk of hydraulic oil leaks, or even make the device unable to work properly.

2、升降貨梯液壓系統(tǒng)的零件會(huì)因?yàn)楣潭ㄊ缴禉C(jī)液壓油溫度過高而受熱膨脹，使得相對運(yùn)動(dòng)的零件之間無法保持一個(gè)正常的配合間隙，導(dǎo)致摩擦阻力增大，從而讓液壓系統(tǒng)的零件磨損過快。
Hydraulic system components because of stationary lift hydraulic oil temperature is too high thermal expansion, making it impossible to maintain a normal with the gap between the relatively moving parts, resulting in increased frictional resistance, so that the hydraulic system parts wear too fast.

3、升降貨梯液壓油溫度過高會(huì)加速橡膠密封件會(huì)加速老化，導(dǎo)致密封性能變差，讓液壓油更容易發(fā)生泄漏，液壓油發(fā)生水分蒸發(fā)，讓液壓元件出現(xiàn)穴蝕的現(xiàn)象。
lift hydraulic oil temperature will accelerate the aging of the rubber seals will accelerate, leading to deterioration of the sealing performance, so more prone to leakage of hydraulic oil,hydraulic oil and water evaporation occurs, so that the hydraulic components appear cavitation phenomenon.

4、升降貨梯液壓油溫度過高會(huì)使液壓油發(fā)生氧化，產(chǎn)生膠狀沉積物，導(dǎo)致液壓閥內(nèi)的小孔出現(xiàn)堵塞，使液壓系統(tǒng)無法正常的進(jìn)行工作。
Stationary hydraulic lift hydraulic oil temperature is too high oil oxidation, resulting gummy deposits, causing the hydraulic valve orifice blockage within the hydraulic system can not work normally.
