Regularly check whether the filter is blocked or damaged, and replace the twisted oil discharge pipeline to ensure the smoothness of the oil return pipeline. At the same time, pay attention to clean the ventilation hood on the side of the transmission shaft frame, and use compressed air to purge the long core hole connecting the hood on the transmission shaft frame.
Check whether the clearance between the inner wall of the oil pool of the main engine base and the oil baffle on the counterweight is reasonable, so as to prevent the lubricating oil splashing on each other from forming an oil seal, thus causing cement mill to break and leak.
