选择工业润滑油，关键在于根据机械设备的情况，也就是机械设备的工作负荷、速度、温度及环境条件，同时还应该考虑工业润滑油的性能。
The key to choose industrial lubricating oil is to consider the working load, speed, temperature and environmental conditions of mechanical equipment, as well as the performance of industrial lubricating oil.
机械设备的工作载荷
Working load of mechanical equipment
选择先从机械设备的工作载荷出发，工作载荷越大使用油品的粘度也就越大，并且要求润滑油品具有良好的抗极压性，而载荷不是很大的话，选用的润滑油品粘度相对而言就会小些。具体可根据实际的机械设备的载荷来选定。
Starting from the working load of the mechanical equipment, the greater the working load, the greater the viscosity of the used oil, and the lubricating oil is required to have good extreme pressure resistance. If the load is not large, the viscosity of the selected lubricating oil will be relatively small. It can be selected according to the actual load of mechanical equipment.
机械设备的温度
Temperature of mechanical equipment
选用应当考虑机械设备的温度，因为温度直接影响工业润滑油的粘度变化和氧化变质。对于长期处在高温条件下运转的机械设备，则应当选购粘度大、粘度指数高、闪点高和抗氧化安定性好的润滑油品。
The selection should consider the temperature of mechanical equipment, because the temperature directly affects the viscosity change and oxidation deterioration of industrial lubricating oil. For machinery and equipment operating under high temperature for a long time, lubricating oil with high viscosity, high viscosity index, high flash point and good anti-oxidation stability should be selected.
机械设备的环境
Environment of mechanical equipment
对于处在低温环境下的机械设备，则应当选用低温性能好的工业润滑油。
For mechanical equipment in low temperature environment, industrial lubricating oil with good low temperature performance should be selected.
