If you have carefully studied the hydraulic cylinder, you can find that its internal structure is very unique. Because the rotary seal directly divides the cylinder into two cavities, the hydraulic cylinder usually has two oil ports. In this case, each oil port corresponds to a cavity. How are these two ports judged?
When the casing is fixed, when one of the oil ports enters the liquid, it will also promote the rotation of the spline sleeve to move in the direction of the other oil port, thereby driving the rotation of the shaft, thus completing the export of the flange. rotate. If the export flange is used for fixing, the same principle is used, and the rotation of the shell is finally realized.
Therefore, when the hydraulic system is installed, the first thing to do is to check whether the installation of each part of the hydraulic system is correct, whether the pipeline connection is correct, etc., according to the schematic diagram, assembly drawing, electrical control diagram of the hydraulic system, etc. A malfunction occurred during work.
