Causes And Countermeasures Of Hydraulic Cylinder Shock Phenomenon
Throttling buffer device failure: Various factors can lead to the failure of the throttling buffer device in the hydraulic cylinder. Possible solutions include replacing the steel ball, grinding the valve seat joint, replacing damaged paper pads, tightening the lock nut, remaking the piston, or adjusting the clearance between the piston and cylinder hole.
Buffer plunger wear: If the outer edge of the buffer plunger and the inner hole of the end cover are worn, causing a large gap, the triangular groove in the buffer plunger may lose its buffering effect. Solutions include remaking the piston and buffer plunger according to the size of the end cover's inner hole, or plating a layer of hard anchor on the buffer plunger's surface and adjusting the clearance accordingly.
Improper adjustment of throttle valve: If the comb nut in the throttle valve is loose or improperly adjusted, it can result in hydraulic shock. Tightening or readjusting the nut can help alleviate the issue.
Issues with one-way throttle valve: If the throttle valve or the one-way valve in the hydraulic reversing valve is not adjusted properly or the seal is faulty, it can cause impact during reversing. Adjusting the throttle valve screw and increasing buffer damping can help. If the issue persists, check the seal of the check valve and its seat.
Air in the hydraulic system: Presence of air in the hydraulic system, especially in the reversing valve, can cause hydraulic shock. Check the air inlet and take preventive measures to remove air from the system.
It's important to note that these solutions are general suggestions and may vary depending on the specific hydraulic system and its components. Consulting the manufacturer's guidelines and seeking professional assistance is recommended to address hydraulic system issues effectively and safely.
