Spring-Return Single-Acting Hydraulic Cylinder For Hydraulic Jacks
Introduction to Spring-Return Single-Acting Hydraulic Cylinder
Spring-return single-acting hydraulic cylinder is a hydraulic cylinder that uses 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, with return depending on the built-in spring.
- Spring selection: The appropriate spring ensures quick and complete reset after pressure release.
- Sealing design: High-quality materials prevent oil leakage and ensure system efficiency.
- Strength and durability: High-strength steel is used to withstand high pressure and impact.
Construction and Assembly Process
The assembly process requires precise docking of components, especially the piston and cylinder block, to reduce friction and wear. Welding and mechanical connections must be strong to prevent oil leakage under high pressure. Testing ensures normal operation after completion.
Working Principle
The single-acting mechanism extends when hydraulic oil enters the cylinder, pushing the piston outward. When pressure is released, the spring mechanism retracts the piston.
Types and Configurations
Three types of spring-return single-acting hydraulic cylinders are available, each with specific configurations to suit different applications.
Key Benefits
- Safety – Automatic reset reduces the risk of accidents.
- Simplicity – Easy design reduces points of failure.
- Cost-effective – Economical compared to double-acting cylinders.
- Flexible operation – Suitable for one-way thrust applications.
Application Scenarios
- Industrial machinery – Press
- Automated assembly line
- Construction equipment – Hydraulic jacks
- Lifting platform
- Agricultural equipment – Agricultural machinery
