1. Regularly check whether the electro-hydraulic thrusters are working normally, whether the oil is sufficient, whether there is leakage, whether the insulation of the lead wire is good, and whether the protective equipment is appropriate and reliable. Check the oil once every six months. When the oil changes and the viscosity increases, it should be replaced in time.
2. When the electro-hydraulic thrusters operate abnormally, the motor will produce noise and vibration, and the bearing should be checked for damage in time. If damaged, it should be replaced in time. Next, check whether the rotor is loose. If it is loose, it should be adjusted in time.
3. When the thrust of the electro-hydraulic thrusters drops, check whether the oil is lacking, and make up for it in time. The voltage of the grid is not lower than 85% of the extra voltage, if it is low, it should advance to the extra value in time.
