The Spring-Return Single-Acting Hydraulic Cylinder
Spring-return single-acting hydraulic cylinder is a specialized hydraulic cylinder that operates using hydraulic oil to expand the piston. When pressure is released, an internal 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 mechanism
Spring Selection
- Appropriate spring choice ensures quick and complete reset after pressure release
Sealing Design
- High-quality sealing materials prevent hydraulic oil leakage
- Ensures system efficiency and safety
Strength and Durability
- Material selection considers high pressure and impact resistance
- Typically uses high-strength steel
Construction and Assembly Process
The assembly process requires precise component alignment, especially piston and cylinder block coordination to minimize friction and wear. Strong welding and mechanical connections prevent oil leakage or breakage under high pressure. Strict pressure and functional testing post-assembly ensures normal hydraulic cylinder operation in practical applications.
Working Principle
The single-acting mechanism propels the piston outward when hydraulic oil enters the cylinder, pushing against the load. Upon pressure release, the spring mechanism retracts the piston to its original position.
Types and Configurations
There are three main types of spring-return single-acting hydraulic cylinders, each with unique configurations tailored for specific applications.
