The precise oil change cycle of ZQ250-15.75-II in high humidity environment can be directly executed on site:
1. Comparison of standard working conditions vs. high humidity working conditions
Normal dry environment : Replace every 8 to 12 months
High humidity/humidity/condensation-prone environment :
Must be shortened to once every 6 months (180 days)
2. Why should the period of high humidity be shortened to 6 months?
Moisture will cause the oil to emulsify, turn white, and become thinner , causing the lubricating film to fail prematurely.
Moisture will corrode gears and bearings , and the more they drag, the greater the damage.
ZQ250 is a commonly used medium-load model and is particularly sensitive to water.
3. If the following situations occur, change the oil immediately without waiting for 6 months.
The oil is white, turbid, and looks like milk
There are water droplets and layers in the oil
Abnormally high operating temperature
Long downtime before restarting
4. Oil recommendations for ZQ250 in high-humidity environments
