Spring-Return Single-Acting Hydraulic Cylinder In Industrial Applications

Introduction to Spring-Return Single-Acting Hydraulic Cylinder

The spring-return single-acting oil cylinder is a hydraulic cylinder that utilizes 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 the return is dependent on the spring.
  • Spring Selection: Appropriate springs are chosen for quick and complete reset after pressure release.
  • Sealing Design: High-quality sealing materials prevent oil leakage for efficiency and safety.
  • Strength and Durability: High-strength steel is chosen for materials to withstand high pressure and impact.

Construction and Assembly Process

The assembly process requires precise component alignment, especially for the piston and cylinder block to reduce friction and wear. Strong welding and connection methods prevent oil leakage under high pressure. Testing and debugging ensure proper operation.

Working Principle of Spring-Return Single-Acting Hydraulic Cylinder

When hydraulic oil is pumped into the cylinder, it pushes the piston outward against the load. Upon pressure release, the spring mechanism retracts the piston to its initial position.
