Replace the dust seal in time, and it is forbidden to frequently hit the self-feeding flat mixer truck.

The occurrence of black oil in the hydraulic system of the self-feeding flat mixer truck is not only caused by dust, but may also be caused by the irregularity of adding butter. When filling butter, the self-feeding flat mixer truck should be lifted, and the steel brazing should be pressed into the piston. Each filling only needs to be filled to the half-gun range of the standard grease gun. If the steel drill is not pressed when adding the butter, the added butter will be at the upper limit of the steel drill groove. When the steel drill is working, the butter will directly jump to the main oil seal position, and the butter will be brought to the position of the main oil seal with the reciprocating motion of the piston. In the middle cylinder, the hydraulic oil in the middle cylinder is mixed into the hydraulic system of the self-feeding flat mixer truck, resulting in abnormal conditions such as deterioration and blackening of the hydraulic oil.

Install a return oil filter device to remove external dust. When replacing hydraulic accessories such as oil pipes, steel pipes, and oil return filter elements, it is necessary to clean up the dust or debris at the interface before loosening and replacing.
