To check the lubricating oil condition of the K67-20-4KW-4P hard tooth surface reducer, you can follow the following steps:
1. Cut off the power supply and cool : Cut off the reducer power before inspection to prevent the risk of electric shock, wait for the reducer to cool down, avoid high-temperature scalding, and at the same time, it can stabilize the lubricant and facilitate accurate inspection.
2. Check the oil level : Find the oil level screw plug of the reducer, which is usually located on the side of the reducer housing. Unscrew the oil level screw plug and observe the oil level. If the oil level is near the oil level screw plug hole or slightly lower than the orifice, it means that the oil volume is normal; if it is significantly lower than the orifice, the oil volume is insufficient and lubricating oil needs to be added. For reducers with oil level windows, you can directly observe the windows. The oil level should be stable between 1/2 and 2/3 of the windows during operation, and should also be within a reasonable range when shutting down. If it is lower than the lower warning line, oil must be replenished.
3. Check the quality of the oil : Open the drain screw plug and take a small amount of oil sample into a clean container. Observe the color and transparency of the oil. Normal lubricating oil should have a uniform color and good transparency. If the oil is turbid, precipitates or abnormal color, it means that the oil quality is deteriorating and you need to consider replacing the lubricant. You can also feel the viscosity of the oil through touch. If the viscosity changes significantly, if it becomes thinner or thicker, it also needs to be replaced. If possible, a portable oil detector can be used to detect indicators such as viscosity and moisture content. When the viscosity of the new oil drops by more than 15% or the moisture content exceeds 0.03%, the oil must be changed.
4. Check whether there is any leakage : Check the joint surfaces, oil seals and other parts of the reducer shell to see if there are any traces of lubricating oil leakage. If oil leakage is found, the cause should be found and dealt with in time, such as replacing the seal, etc.
5. Install the oil level screw plug : After the inspection is completed, tighten the oil level screw plug to ensure a good seal and prevent lubricant leakage and dust and other impurities from entering.
