Introduction to Spring-Return Single-Acting Hydraulic Cylinder for Lifting Tables
Definition of Spring-Return Single-Acting Hydraulic Cylinder
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: Operates in one direction through hydraulic oil pressure, return relies on built-in spring.
- Spring Selection: Appropriate spring chosen for quick and complete reset post hydraulic oil pressure release.
- Sealing Design: High-quality sealing materials to prevent oil leakage and ensure system efficiency.
- Strength and Durability: Material selection considers strength to withstand high pressure and impact.
Construction and Assembly Process
Assembly process requires precise docking of components, especially piston and cylinder block coordination to reduce friction and wear. Strong welding and mechanical connections are crucial to prevent oil leakage or breakage under high pressure. After assembly, rigorous pressure and functional testing ensure proper operation.
Working Principle of Spring-Return Single-Acting Hydraulic Cylinder
When hydraulic oil is pumped into the cylinder, it pushes the piston outward against the load. Upon pressure release, the spring mechanism retracts the piston to its original position.
Types and Configurations
Three different types of spring-return single-acting hydraulic cylinders offer various configurations tailored to specific needs.
Key Benefits
- Safety – Automatic Reset: Spring resets piston automatically, enhancing operational safety.
- Simplicity – Simple Design: Easy to understand, operate, maintain, and repair.
