Introduction to Spring-Return Single-Acting Hydraulic Cylinder
The spring-return single-acting hydraulic 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 only operates in one direction, while the return relies on the built-in spring.
- Spring Selection: The appropriate spring must be chosen to ensure quick and complete reset after pressure release.
- Sealing Design: High-quality sealing materials are used to prevent oil leakage and ensure system efficiency.
- Strength and Durability: Material selection considers high pressure and impact resistance, typically using high-strength steel.
Assembly Process
The assembly process must ensure precise component alignment, especially the piston and cylinder block, to minimize friction and wear. Welding and mechanical connections should be strong to prevent oil leakage or breakage under high pressure. Testing and debugging are essential to verify proper functionality.
Working Principle
When hydraulic oil enters the cylinder, it pushes the piston outward against the load. Upon pressure release, the spring mechanism retracts the piston to its initial position.
