Why does the piston rod leak out?

During the assembly process of the piston rod of the oil cylinder, no protection measures have been taken for it, which is mainly reflected in the process of painting the whole machine of construction machinery, and no relevant protection measures have been taken for the dustproof ring of the hydraulic cylinder. , resulting in more paint remaining on the lip of the dust seal, which affects the use of the dust seal.
The main components of the double-acting single-rod piston hydraulic cylinder can be divided into piston, cylinder head, cylinder barrel, piston rod head, piston rod, cylinder bottom and related auxiliary devices, etc., and the piston will directly divide the cylinder into left and right parts. The two different chambers will reciprocate inside the entire cylinder with the help of the main function of the pressure oil. In order to effectively improve the effect of its use, it is necessary to add a sealing ring to the piston rod to prevent it from leaking. When the piston rod passes through the cylinder head, because there is a large gap between the two, for example, it is prone to leakage, and dust will also enter the cylinder body through the gap, so it is necessary to set up a sealing device or a Dust ring.
Because the piston rod of the oil cylinder plays the role of an executive component in the construction machinery, so the temperature of the quality will directly affect the reliability and work efficiency of the entire construction machinery.
