What is the oil change cycle for ZQ250-15.75-II gearbox in high humidity environment

ZQ250-15.75-II's precise oil change cycle in high humidity environments can be directly executed on site:
1、 Comparison between standard operating conditions and high humidity operating conditions

Normal dry environment: Change every 8-12 months

High humidity/humid/prone to condensation environment:

Must be shortened to once every 6 months (180 days)

This is the gearbox, bearings, and seal
The safest lifespan
The cycle.
2、 Why does high humidity shrink to 6 months

Moisture can cause oil emulsification, whitening, and thinning, leading to premature failure of the lubricating film

Moisture can corrode gears and bearings, and the more it is dragged, the greater the damage

ZQ250 is a commonly used mid-range aircraft model and is particularly sensitive to water

3、 If the following situations occur, there is no need to wait for 6 months, change the oil immediately

The oil appears white, cloudy, and resembles milk

There are water droplets and layers in the oil

Abnormal increase in operating temperature

Long downtime and before restarting
