1、高温影响固定升降机http://www.rgsjpt.com/液压系统的润滑油长期处在高温环境中，会氧化失效，出现变黑、变稠的现象。
Hydraulic lift system to high temperature lubricants fixed long-term in a high temperature environment, will oxidize failure appear black, thickening phenomenon.

2、固定升降机杂质主要来源于空气中的尘埃、金属磨粒、渗漏物(燃油、水等)、润滑油氧化物以及燃料燃烧产生的物质等。
Fixed lifts impurities mainly from dust in the air, the metal grains, leakage material (fuel, water, etc.), as well as lubricants oxide substances produced by fuel combustion.

3、固定升降机添加剂失效润滑油中的抗磨剂用完，会使福建升降平台的液压系统的抗磨性下降。
Fixed lift failure lubricating oil additives, anti-wear agents run, make the hydraulic system lifting platform Fujian abrasion resistance decreases.

4、固定升降机http://www.rgsjpt.com/基础油是添加剂的载体，基础油失效则添加剂不会发挥作用。
Fixed lift base oil is a carrier additives, base oil additives do not play a role in the failure.
