What is the working principle of Hydraulic Lifting Cylinders?

Hydraulic lift cylinders convert fluid power into precise mechanical force, enabling industrial companies to lift enormous loads with unparalleled control. At TOLENG, we leverage cutting-edge design and technology to provide you with highly reliable and safe hydraulic cylinders. Do you understand how hydraulic lift cylinders work?

Working Principle

Fluid Pressurization: A hydraulic pump pressurizes oil into the cylinder, creating a high-pressure zone.

Piston Actuation: Pressure pushes the piston, driving the piston rod outward to lift the load.

Controlled Retraction: Reversing fluid flow causes the piston rod to retract smoothly.

FAQ

Q: What is the basic physical principle behind Hydraulic Lifting Cylinders?

A: Pascal's principle: In a confined space, pressure applied to hydraulic fluid is evenly distributed. For example, a pressure of 10 bar acting on a 100 cm² piston generates a force of 1,000 kg.

Q: Why are TOLENG hydraulic cylinders more energy efficient than competitors?

A: Our proprietary pressure-compensated flow control technology reduces heat generation, resulting in a 30% reduction in energy consumption compared to the industry average. Combined with low-friction seals, this ensures smooth operation at a noise level of ≤55 dB.

Q: How do seals prevent leakage in high-pressure environments?

A: TOLENG utilizes triple-lip sealing technology: a reinforced PTFE layer creates a redundant barrier. Each seal undergoes over 5,000 pressure cycles during testing, ensuring it remains leak-free even at 700 bar—critical for aerospace and offshore applications.
