Exploring the Spring-Return Single-Acting Hydraulic Cylinder for Compact Excavators

Introduction to the Spring-Return Single-Acting Hydraulic Cylinder

Spring-return single-acting oil 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 is used to move the piston in one direction, with the return dependent on the spring.
• Spring Selection: Choosing the right spring ensures quick and complete reset after pressure release.
• Sealing Design: High-quality seals prevent oil leakage and ensure system efficiency.
• Strength and Durability: High-strength materials are selected to withstand high pressure and impact.

Construction and Assembly Process

The assembly process requires precise component alignment, especially for the piston and cylinder block, to reduce friction and wear. Strong welding and connections are essential to prevent oil leakage under high pressure. Testing and debugging are crucial to ensure proper functionality.

Working Principle of the Spring-Return Single-Acting Hydraulic Cylinder

When hydraulic oil is pumped into the cylinder, it pushes the piston outward. The spring mechanism retracts the piston when the pressure is released.
