Spring-Return Single-Acting Hydraulic Cylinder In Underwater Applications

Introduction

Spring-return single-acting oil cylinder is a hydraulic cylinder that uses hydraulic oil to expand the piston. When the pressure is released, the built-in spring automatically retracts the piston.

Design and Construction Characteristics

• Single-acting structure: Hydraulic oil pressure in one direction, return depends on the built-in spring.
• Spring selection: Appropriate spring for quick and complete reset after pressure release.
• Sealing design: High-quality materials to prevent oil leakage.
• Strength and durability: Material selection for high pressure and impact resistance.

Construction and Assembly Process

The assembly process requires precise component docking, especially piston and cylinder block coordination. Welding and connections must be strong to prevent oil leakage under high pressure. Strict testing and debugging ensure normal operation.

Working Principle

When hydraulic oil enters the cylinder, it pushes the piston outward. The spring mechanism retracts the piston when hydraulic pressure is released.
