How often should the coupling oil be changed?

[VanAnnie]

Coupling oil should be changed every three years. Here are the precautions for coupling oil filling: 1. Oil type: Usually, non-flammable hydraulic oils such as No. 8 hydraulic oil or No. 32 hydraulic oil are used, and gear oil must not be added. Oil filling is strictly prohibited in hydraulic couplings (except for adjustable-speed hydraulic couplings), as it may cause explosions or fires. 2. Oil filling amount: The filling amount should be 70%-80%. For ordinary torque-limiting hydraulic couplings, the filling amount corresponds to 80% of the rated power. Tilt the oil filler at a 45° angle from the vertical direction, and fill until the oil just starts to flow out. Typically, the filling range for YOX-type couplings is 40%~80%.
