Introduction

Spring-return single-acting hydraulic cylinder is a crucial component in hydraulic systems, utilizing hydraulic oil to expand the piston and a built-in spring to retract it upon pressure release.

Design and Construction Characteristics

• Single-acting Structure: Hydraulic oil pressure drives movement in one direction, while the spring facilitates return.
• Spring Selection: Optimal spring choice ensures swift and complete piston reset post-pressure release.
• Sealing Design: High-quality seals prevent oil leaks, ensuring system efficiency and safety.
• Strength and Durability: Use of high-strength materials like steel withstands high pressure and impact.

Construction and Assembly

The assembly process requires precision in component alignment, especially piston-cylinder block coordination, to minimize wear and friction. Strong welding and connections prevent oil leakage under pressure. After assembly, rigorous testing ensures proper functionality.

Working Principle

During operation, hydraulic oil extension pushes the piston, and upon pressure release, the spring mechanism retracts it, creating a continuous cycle.

Types and Configurations

Three main types of spring-return single-acting hydraulic cylinders offer varied configurations to suit different applications.

Key Benefits

• Safety: Automatic piston reset enhances operational safety.
