Basic Principles of Hydraulic Intensifiers

Are you familiar with hydraulic intensifiers? It uses a low-pressure hydraulic power source to generate a higher pressure. Typically, the device is used when a pump alone cannot produce the high pressure required. Presses, jacks, torque wrenches, work holding, die casting, hydraulic power packs, and more are some of the applications. An article below explains how hydraulic pressure intensifiers work

What is the position of a hydraulic intensifier?

During system design, a hydraulic intensifier is precisely positioned between the pump and the working machine. This design allows the hydraulic pressure produced by the pump to be intensified and transferred to the working machine for clamping, holding, punching, lifting, etc.

Hydraulic architectures are included in compact hydraulic pressure intensifiers. With this device, you can increase the low pump pressure to 1000 psi or 6000 psi, or even 20,000 psi to 60,000 psi. An intensifier can be integrated into any hydraulic circuit, whether it is an in-line model, a flange-on model, or a cartridge model.

What are the important components of a hydraulic intensifier?

A compact intensifier consists of four elements: a fixed cylinder, a sliding cylinder/RAM, a fixed RAM, and check valves. Low-pressure liquid enters the intensifier through its exterior body from Main supply. Located inside the fixed cylinder, the sliding cylinder/RAM stores high-pressure liquid, while low-pressure liquid enters the intensifier via its exterior body, which includes four valves for supplying and draining hydraulic pressure.

What is the working principle of a hydraulic intensifier?

An The intensifier compresses hydraulic system fluid above the pump's discharge pressure. The intensifier operates when the sliding cylinder is in its bottom-most position, which is considered to be at rest. A valve (let's call it 'A') will allow the low-pressure fluid from the pump to enter and fill the fixed cylinder. Other valves will be closed during this process. Through another valve (say 'B'), the low-pressure fluid enters the ram or sliding cylinder. A valve (let's call it valve 'C') discharges the low-pressure fluid from the fixed cylinder after it has been diverted to the exhaust. The sliding cylinder will move upwards when the low-pressure fluid leaves the fixed cylinder due to the fluid supply from 'B'. The valves "D" and "A" are opened when the sliding cylinder has filled with low-pressure fluid, allowing the low-pressure fluid to enter the fixed cylinder through valve "A". Pushing the sliding cylinder downward causes high-pressure fluid to be produced inside of it. High-pressure fluid is discharged through valve "D."
