In particular, if you want to drain all the oil in the DC geared motor box, you need to open the oil drain plug at the bottom of the box to drain the oil. You must know that the oil level of the DC geared motor is on the top of the fuel tank when the oil is drained outside. The purpose of the requirement that the height cannot exceed 30mm is also to ensure the lubrication and cooling effect of each bearing inside the DC geared motor.
The variable-speed hydraulic DC gear motor needs to change the oil and clean the oil tank after the first 500h operation, because we need to check the oil quality used. If the oil quality is found to be bad, it needs to be replaced in time. In the process of oil change, it is necessary to clean the oil tank and oil filter of the DC geared motor at the same time. If metal chips or water are found in the process, the cause of the problem needs to be found and solved as soon as possible.
