The reasons for the hydraulic cylinder piston slipping in the guardrail pile driver. The cause of piston slip in Hydraulic Cylinder 1 of the pile driver is improper installation of internal components in the hydraulic cylinder before stopping, deformation of components due to public service, wear, or excessive restriction. The piston speed and stroke direction of the hydraulic cylinder are different due to excessive core resistance, presenting sliding or squeezing phenomena. The fundamental cause is poor component quality, scratches on the outer surface, or iron filings produced by sintering, leading to increased resistance and reduced speed. For example, if the piston does not match the piston rod or the piston rod is serrated, the hydraulic cylinder or piston rod deviates from the direction of the guide device, the sealing ring is too tight or too loose, it may cause the inner cylinder to stay from the beginning, repair or adjust, replace damaged parts, and timely remove iron filings. Poor machining of the hydraulic cylinder bore in guardrail pile drivers causes the piston and cylinder body to move relative to the guide rail. Due to different bore machining, when the piston works in the hydraulic cylinder, wear intensifies, the centerline linearity decreases, and friction resistance is great. When the time is short, it may slip or break. First, grind the hydraulic cylinder, then make the piston, repair the piston rod, set the guide sleeve, and solve the problem of poor machining of Hydraulic Cylinder 3. When the hydraulic pump or hydraulic cylinder takes in air, whether the air is compressed or expanded, the piston will slide or break; the guardrail pile driver's hydraulic pump is equipped with a special exhaust device, capable of rapid and multiple operations, allowing it to enter the hydraulic pump or hydraulic cylinder.

IV. Seal Quality The commonly used seals mainly include O-rings and U-rings; when the O-ring is used under low pressure, the surface pressure is high, and the change in dynamic friction resistance is large, leading to sliding or sagging; as the surface pressure of the U-ring increases with pressure, the sealing effect also increases, but the increase in dynamic friction resistance and internal pressure will affect the elasticity of the rubber and increase the contact resistance of the lip, elongation of the sealing flap or lip can cause sliding or hooking, and support rings will prevent the issue of seals flipping causing piston sliding in the hydraulic cylinder of the guardrail pile driver.
