Expanded Introduction
The 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.
Spring-return single-acting hydraulic cylinders are commonly used in various industrial applications due to their efficiency and safety features.
Design and Construction Characteristics
Single-Acting Structure
Spring-return single-acting hydraulic cylinders operate in one direction through hydraulic oil pressure, with the return function relying on the built-in spring.
Spring Selection
Choosing the appropriate spring is crucial to ensure a quick and complete reset after the hydraulic oil pressure is released.
Sealing Design
High-quality sealing materials are essential to prevent hydraulic oil leakage and maintain system efficiency and safety.
Strength and Durability
Material selection should prioritize strength to withstand high pressure and impact, typically using high-strength steel.
Construction and Assembly Process
