Exploring the Spring-Return Single-Acting Hydraulic Cylinder
Introduction to the Keywords
The spring-return single-acting hydraulic 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: Hydraulic oil pressure in one direction, return through built-in spring
- Spring Selection: Appropriate spring ensures quick and complete reset
- Sealing Design: High-quality materials prevent oil leakage
- Strength and Durability: High-strength steel for high pressure and impact
Construction and Assembly Process

- Precision assembly of components
- Strong welding and mechanical connections
- Testing and debugging for operational efficiency
Working Principle
Fluid enters the cylinder, extending the piston when pressure is applied. The spring mechanism retracts the piston when pressure is released.
