Spring-Return Single-Acting Hydraulic Cylinder Seal Types

Exploring the Spring-Return Single-Acting Hydraulic Cylinder Seal Types

Introduction

The spring-return single-acting oil cylinder is a hydraulic cylinder that utilizes 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: The hydraulic oil pressure operates in one direction, with the return function dependent on the built-in spring.
  • Spring Selection: Appropriate springs are chosen to ensure a quick and complete reset after the pressure release.
  • Sealing Design: High-quality materials are used to prevent oil leakage and ensure system efficiency and safety.
  • Strength and Durability: Materials are selected for their ability to withstand high pressure and impact, typically high-strength steel.

Construction and Assembly Process

  • Assembly Precision: Components must be precisely aligned to reduce friction and wear.
  • Welding and Connection: Strong welding and mechanical connections prevent oil leakage or breakage under high pressure.
  • Testing and Debugging: Pressure and functional testing ensure proper operation post-assembly.

Working Principle

The single-acting mechanism pushes the piston outward with hydraulic oil and retracts it with the spring mechanism.
