Expanding the Key Words: Spring-Return Single-Acting Hydraulic Cylinder for Gate Automation
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
- Operates in one direction through hydraulic oil pressure
- Return depends on the built-in spring
Spring Selection
- Appropriate spring selection for quick and complete reset
Sealing Design
- High-quality sealing materials to prevent oil leakage
Strength and Durability
- Material selection for high-pressure and impact resistance
Construction and Assembly
Assembly process ensures precise docking of components and coordination of piston and cylinder block to reduce friction and wear.
Welding and Connection
- Strong welding and mechanical connections to prevent oil leakage
Testing and Debugging
- Strict pressure and functional testing for operational efficiency
Working Principle
Spring-return single-acting hydraulic cylinder operates through hydraulic oil pressure extending the piston and spring mechanism retracting it.
