Comparison Of Spring-Return Single-Acting Hydraulic Cylinders


Comparison Of Spring-Return Single-Acting Hydraulic Cylinders

Introduction

Spring-return single-acting hydraulic cylinders utilize hydraulic oil to expand the piston. When pressure is released, the built-in spring automatically retracts the piston.

Design and Construction Characteristics

  • Single-Acting Structure: Hydraulic oil pressure is used for extension, while return is dependent on the built-in spring.
  • Spring Selection: Appropriate spring choice ensures quick and complete reset after pressure release.
  • Sealing Design: High-quality materials prevent oil leakage and ensure system efficiency.
  • Strength and Durability: Material selection considers strength to withstand high pressure.

Construction and Assembly

Assembly precision is crucial to minimize friction and wear. Welding and connections must be strong to prevent oil leakage under pressure. Testing is essential for proper functionality.

Working Principle

Hydraulic oil extension pushes the piston against the load. Spring mechanism returns the piston to its initial position when pressure is released.
