How to improve the life of the coupling
1. The coupling should be lubricated with lithium soap-based grease containing pressure additives.Examples include but are not limited to ESSO Beacon EP and Mobil Temp 78.There are many alternatives to choose from, because almost every grease manufacturer makes greases for this and similar applications.It is very important that different types of greases cannot be mixed, and even the differences of the same type of grease should be checked for compatibility before use.Please consult us for special applications such as high speed, temperature, humidity or water for special recommendations.
2. After shrinking and installing the hub on the shaft and positioning the gear sleeve, the cavity between the hub and the sleeve should be filled with grease with a spatula.A thin layer of glue film should be applied to the mating flange surface, and the connecting bolts should be tightened to an appropriate torque. After connecting the half flanges, fill the pipe joints through the grease nipple.When filling through the grease filling port, make sure that the pipe joint is being filled.If filling is difficult, remove the grease nipple or plug.Once it is determined that the pipe joints have been filled, replace any grease nipples or plugs that have been removed and tighten them correctly.
3. After 3 months before operation, the coupling should be relubricated.Since then, the lubrication interval can be extended to 6 months, but not more than 1 year.The lubrication interval should take into account the severity of the operation.
4. When lubricating, completely change the grease in the coupling.Remove the grease nipple 180° from the nipple used to fill the pipe joint.Pump in fresh grease until the grease starts to drain from the opening.Once you are sure that the pipe joints have been filled, please replace any grease or plugs that have been removed and tightened correctly.
5. Every 8000 hours or 2 years of work, the coupling should be opened, grease, and replaced with new grease.The flange surface should be cleaned and reconnected as described in point 2 above.
