It consists of a cylindrical barrel, a piston, and a piston rod.
Here are some key features and characteristics of RAM hydraulic cylinders:
Construction: A RAM hydraulic cylinder typically consists of a cylindrical barrel that houses the piston and seals. The piston is connected to a piston rod that extends from one end of the cylinder. The other end of the cylinder is typically closed with an end cap. RAM cylinders are designed for uni-directional force application, meaning they generate force in one direction only, typically by extending the piston rod.
Single-Acting Operation: RAM cylinders are single-acting, meaning they generate force in one direction during operation. They are usually powered by hydraulic fluid, which enters the cylinder through a port or line, applying pressure on one side of the piston. The hydraulic force generated pushes the piston and extends the piston rod, generating linear force in the desired direction. Retraction of the piston is typically achieved by other means, such as gravity or a spring.
Application: RAM hydraulic cylinders are commonly used in applications where force is required in one direction only. They are utilized in various industries, including construction, agriculture, material handling, and manufacturing. Examples of applications include hydraulic presses, lifting equipment, dump trucks, and hydraulic jacks.
Mounting Options: RAM cylinders can be mounted in different ways depending on the specific application requirements. Common mounting options include flange mounts, clevis mounts, trunnion mounts, and foot mounts. The mounting style should be selected based on the application and the available space for installation.
Sealing: RAM cylinders utilize hydraulic seals to prevent hydraulic fluid leakage and maintain pressure within the cylinder. The seals are typically located on the piston and piston rod to maintain a tight seal and ensure efficient operation. Proper sealing is crucial for the performance and longevity of the cylinder.
Stroke Length and Force: RAM cylinders are available in various stroke lengths and force capacities to accommodate different application needs. The stroke length refers to the distance the piston rod can travel, while the force capacity indicates the maximum force the cylinder can exert. These specifications should be selected based on the specific application requirements and load conditions.
Maintenance and Repair: RAM cylinders are designed to be relatively simple and easy to maintain. They can be disassembled for seal replacement or other repairs. Regular inspection, lubrication, and maintenance are important to ensure optimal performance and extend the lifespan of the cylinder.
