The use time reaches the specified period: Generally speaking, the new ZDY100 reducer should undergo the first oil change after 200-300 hours of initial operation. After that, the lubricant must be replaced every 2000-3000 hours or six months to one year (whichever comes first). This is because after long-term use, the lubricant will gradually age and deteriorate, and its performance will decline, and it will not effectively play a role in lubrication, cooling and protection.
Deterioration of oil quality: Through observation or detection, if the lubricant oil has obviously become darker, darker, turbid, with precipitates or impurities, or has a pungent odor, it means that the oil quality has deteriorated and needs to be replaced in time. In addition, if the viscosity, acid value, moisture and other indicators of the lubricant oil are detected to exceed the specified range, it also indicates that the lubricant oil cannot be used normally.
Reducer failure: When the reducer fails, such as gear wear, bearing damage, etc., it may cause impurities such as metal debris to mix into the lubricating oil. Even if the fault is fixed, it is recommended to replace the lubricant to prevent further wear and damage to the reducer by impurities.
Load or working conditions change: If the load of the reducer increases significantly, or the working environment temperature, humidity and other working conditions change significantly, the performance of the lubricant may be affected. At this time, in order to ensure the normal operation of the reducer, it is also necessary to consider replacing suitable lubricating oil. For example, in high temperature environments, it may be necessary to use lubricating oils with better high temperature resistance.
Lubricant oil leakage: When a lubricant oil leakage occurs in the reducer, causing the oil level to drop below the lowest oil level, in addition to timely repairing the leakage area, lubricant needs to be supplemented or replaced. Because lubricating oil leakage will not only affect the lubricating effect of the reducer, but may also cause internal components to be damaged due to oil deficiency.
