升降货梯液压系统过热有哪些危险？

1、一般情况下，升降货梯http://www.jntr168.com/的正常工作温度为40-60度，超过这个温度就会给液压系统带来不利影响。升降货梯液压系统过热可直接影响系统及组件的可靠性、降低升降平台作业效率等。
Under normal circumstances, cargo lifter normal operating temperature is 40-60 degrees, the temperature will exceed the adverse impact on the hydraulic system. Cargo lifter hydraulic system overheating can directly affect the reliability of systems and components, reducing the lifting platform operating efficiency.

2、从最根本上升降货梯液压油温度升高，油液黏度降低油液变稀和泄露增加，造成汽化的同时还会出现较为严重的气蚀现象。
Lift freight elevator from the most fundamental hydraulic oil temperature, oil viscosity thinning and reducing oil leakage increases, resulting in vaporization, while there will be more severe cavitation.

3、升降货梯液压油氧化加剧使用寿命降低甚至会变质失去工作能力。石油基油形成胶状物质会在液压元件局部过热的表面上形成沉积物，容易堵塞节流小孔、缝隙、进回油的滤网，使之不能正常工作从而影响升降货梯的正常工作。 
Cargo lifter hydraulic oil oxidation deterioration intensified reduce the life of even lose the ability to work. Petroleum oil to form a gelatinous substance will form deposits on the surface of the hydraulic components overheating,easy to plug the throttle holes, cracks, back into the oil filter, so that the lift does not work thus affecting the normal operation of the freight elevator.

4、由于大多数液压系统的密封件和高压软管都是橡胶制品或其他非金属制品，温度过高会加速其老化和变质影响其使用寿命。升降货梯http://www.jntr168.com/液压系统过热降引起热膨胀，而不同材质的运动副的膨胀系数不同而使运动副的配合间隙发生变化。间隙变小会出现运动干涉或卡死现象；间隙变大会使泄露增加导致工作性能下降及精度降低，同时也容易破坏润滑油膜加速磨损,最后整个液压升降机的动力性、可靠性工作效率等都会降低。
Due to the high-pressure hoses and seals are most hydraulic systems or other non-metallic products, rubber products, high temperature will accelerate the aging and deterioration affect their life. Cargo lifter hydraulic system overheating caused by thermal expansion of the drop, and change different expansion coefficients of different materials deputy campaign leaving deputy campaign with the gap. Gap smaller movement appears to interfere or stuck phenomenon;gap becomes the General Assembly to make disclosure increases lead to reduced work performance degradation and precision, but also easy to destroy the lubricant film accelerated wear, and finally the power, reliability, efficiency of the entire hydraulic lifts, etc. will reduce.
