升降貨梯液壓系統(tǒng)過熱有哪些危險？

1、一般情況下，升降貨梯http://www.jntr168.com/的正常工作溫度為40-60度，超過這個溫度就會給液壓系統(tǒng)帶來不利影響。升降貨梯液壓系統(tǒng)過熱可直接影響系統(tǒng)及組件的可靠性、降低升降平臺作業(yè)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、從最根本上升降貨梯液壓油溫度升高，油液黏度降低油液變稀和泄露增加，造成汽化的同時還會出現(xiàn)較為嚴(yán)重的氣蝕現(xiàn)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、升降貨梯液壓油氧化加劇使用壽命降低甚至?xí)冑|(zhì)失去工作能力。石油基油形成膠狀物質(zhì)會在液壓元件局部過熱的表面上形成沉積物，容易堵塞節(jié)流小孔、縫隙、進(jìn)回油的濾網(wǎng)，使之不能正常工作從而影響升降貨梯的正常工作。 
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、由于大多數(shù)液壓系統(tǒng)的密封件和高壓軟管都是橡膠制品或其他非金屬制品，溫度過高會加速其老化和變質(zhì)影響其使用壽命。升降貨梯http://www.jntr168.com/液壓系統(tǒng)過熱降引起熱膨脹，而不同材質(zhì)的運(yùn)動副的膨脹系數(shù)不同而使運(yùn)動副的配合間隙發(fā)生變化。間隙變小會出現(xiàn)運(yùn)動干涉或卡死現(xiàn)象；間隙變大會使泄露增加導(dǎo)致工作性能下降及精度降低，同時也容易破壞潤滑油膜加速磨損,最后整個液壓升降機(jī)的動力性、可靠性工作效率等都會降低。
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.
