Main Functions of the Hydraulic Cylinder Repair Bench
- Cylinder Clamping and Support：Adjustable V-shaped supports hold the cylinder barrel and piston rod at multiple positions. They help maintain axial alignment and reduce unwanted movement during repair operations.
- Cylinder Gland Removal：Interchangeable tools can be configured for different gland and cylinder-head designs. The hydraulic torque mechanism assists with initial loosening and final tightening.
- Rod Assembly Extraction：The hydraulically driven movable worktable pulls the piston rod assembly smoothly out of the cylinder barrel. It can also guide the rod assembly back into the barrel during reassembly.
- Piston Nut Removal：Profiled fixtures secure different piston nut designs. Hydraulic force provides the initial breakout action required to loosen tightly assembled piston nuts.
- Hydraulic Rotary Drive：After the gland or piston nut has been loosened, the hydraulic motor provides faster rotation during low-torque threading and unthreading operations.
- Adjustable Hydraulic Control：The centralized hydraulic system supplies power to the movable worktable, torque mechanism and rotary drive. Adjustable pressure allows the operating force to be matched to different cylinder sizes.
