Working Mechanism

The hydraulic fluid enters the extended side of the single-acting, hollow plunger hydraulic cylinder.
Pressurised hydraulic fluid acts on the piston, causing it to move in the direction of extension along the cylinder body.
As the piston moves, it pushes the hollow plunger, which extends outward from the cylinder.
The linear force or motion generated by the extension of the hollow plunger is used to perform the desired task, such as lifting or pushing an object.
To retract the plunger, the hydraulic fluid is released from the cylinder, allowing external forces or a return spring to bring the plunger back to its original position.

Frequently Asked Questions

What factors should be considered while choosing a single-acting hollow-plunger hydraulic cylinder?

Major factors include required load capacity, material & construction, operating pressure, mounting options and stroke length.

How does the single-acting spring return function in a hollow plunger hydraulic cylinder?

The single-acting spring return mechanism ensures that when the hydraulic pressure is released, the plunger retracts smoothly and promptly to its initial position, promoting efficient and dependable operation.

What safety precautions should be considered while using a single-acting hollow-plunger hydraulic cylinder?

Wear appropriate personal protective equipment (PPE) such as safety goggles, gloves and protective clothing.
Inspect the hydraulic cylinder for any signs of damage, leaks, or wear before each use.
Follow the manufacturer's instructions for proper installation & use of the hydraulic cylinder.
Securely anchor or stabilise the cylinder to prevent movement or tipping during operation.
Use the hydraulic cylinder within its specified working pressure and capacity limits.
Regularly inspect and maintain the hydraulic system, including checking fluid levels and ensuring proper connections.
Be cautious of pinch points and keep body parts clear of moving components.
Keep a clear and organised work area to minimise the risk of trips or falls.
Monitor the hydraulic system for abnormal noises, vibrations or temperature changes.
