The Spring-Return Single-Acting Hydraulic Cylinder
Introduction
Spring-return single-acting hydraulic cylinder utilizes hydraulic oil to expand the piston, and when the pressure is released, the built-in spring automatically retracts the piston.
Design and Construction Characteristics
- Single-Acting Structure: Operates in one direction through hydraulic oil pressure, with return depending on the built-in spring.
- Spring Selection: Proper spring selection ensures quick and complete reset after pressure release.
- Sealing Design: High-quality seals prevent oil leakage, ensuring system efficiency and safety.
- Strength and Durability: Material selection considers strength to withstand high pressure and impacts, typically high-strength steel.
Construction and Assembly Process
The assembly process requires precise component alignment to reduce friction and wear. Welding and mechanical connections must be strong to prevent oil leakage under high pressure. Strict testing and functional testing are essential post-assembly.
Working Principle
When hydraulic oil is pumped into the cylinder, it pushes the piston outward against the load. Upon pressure release, the spring mechanism pulls the piston back to its initial position.
