How to determine whether the lubricating oil of YCJ225/Y132M-7.5-B3 reducer needs to be replaced

To determine whether the lubricating oil of YCJ225/Y133M-7.5-B3 reducer needs to be replaced, the following methods can be used:

1、 Regular inspection

Time cycle: Change the oil for the first time after running for 200 hours, and then adjust according to the running time:

High load operation (over 10 hours per day): Replace every 3 months.

Low load operation (≤ 10 hours per day): Replace every 6 months.

Long term disuse (over 12 months): must be replaced before reuse.

2、 Oil condition monitoring

Total acid value: If it significantly exceeds the initial value, it indicates an increase in oxides and needs to be replaced.

Moisture content: Exceeding the standard will damage the oil film, accelerate corrosion, and require immediate replacement.

Metal analysis: Abnormal content of metals such as copper, aluminum, and iron indicates wear or additive failure.

Particle count: Excessive particle count indicates severe pollution and needs to be replaced.

Viscosity change: If the viscosity increases by more than 10%, the lubrication effect decreases and needs to be replaced.

3、 Environment and working conditions

Adverse environment (high temperature, high humidity, high dust): Shorten the oil change cycle.

High load operation: The lubricating oil performance deteriorates rapidly, and the cycle needs to be shortened.

4、 Operational suggestions

First oil change: Thoroughly remove dirty oil after 200 hours of operation.

Routine maintenance: regularly check the oil color, viscosity and foam, and replace them immediately in case of abnormality.

Testing tools: Use professional equipment such as acid value meter, moisture meter, viscosity meter, etc.

By using the above methods, the lubricating oil status can be systematically determined to ensure stable operation of the equipment.
