Understanding Spring-Return Single-Acting Hydraulic Cylinders
Introduction to Spring-Return Single-Acting Hydraulic Cylinders
Spring-return single-acting oil cylinders are hydraulic cylinders that utilize 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 moves the piston in one direction, with spring return.
- Spring Selection: Choose the right spring for quick and complete reset after pressure release.
- Sealing Design: High-quality materials prevent oil leakage for system efficiency and safety.
- Strength and Durability: Use high-strength steel for handling high pressure and impact.
Construction and Assembly Process
Assembling involves precise component docking, especially piston and cylinder block alignment, to reduce friction and wear. Strong welding and connections prevent leaks under high pressure. Testing ensures proper functionality.
Working Principle of Spring-Return Single-Acting Hydraulic Cylinders
The single-acting mechanism extends the piston when oil enters the cylinder and retracts it with spring force upon pressure release.
