There are reasons for mechanical leakage. For example, the reliability of the hydraulic system depends to a large extent on the design of the hydraulic system seal and the selection of seals. Due to the unreasonable selection of the seal structure in the design, the selection of the seals does not meet the specifications. In the design, the compatibility of hydraulic oil and sealing materials, load conditions, ultimate pressure, working speed, and changes in ambient temperature were not considered.
These all directly or indirectly cause hydraulic system leakage to varying degrees. In addition, due to the dust and impurities in the operating environment of construction machinery, suitable dust-proof seals should be selected in the design to prevent dust and other dirt from entering the system to damage the seal and contaminate the oil, thereby causing leakage. The design takes into account that the geometric accuracy and roughness of the moving surface is not comprehensive enough, and the strength of the connection part is not checked in the design, which will cause leakage in the work of the machine.
It can be seen that there are many factors that cause mechanical leakage. If the mechanical seal performance of the honing pipe is good, first of all, the material selection must be paid attention to when designing and manufacturing, and the correct operation must be performed to make it work properly.
