How They Work
The working principle of the hydraulic lift chair is to use the pressure generated by the hydraulic oil to lift the chair. The lifting speed is relatively slow, but the generated force is large, making it well-suited for barbershops.
Hydraulic chairs use hydraulics to raise and lower the seat of the chair. The hydraulic fluid is in a closed system and is not exposed to air, so there is no leakage. Chairs are operated by a hand pump connected to the hydraulic system. There are two main types of hydraulic chairs: electric and manual. Electric hydraulic chairs are the luxury segment, equipped with features to raise and lower the chair automatically via a button or foot pedal.
When repairing an office chair, the mechanism is a key aspect. It’s usually found in a compact box housing many gears that permit a wide range of movement and adjustment.
Types and Features
Electric vs Manual Hydraulic Chairs
Electric hydraulic chairs come with a higher price range and often have a tilt function that adds comfort for the clients. On the other hand, manual hydraulic chairs require manual effort to adjust but can be found at a lower cost.
Office Chair Hydraulics
The office chair hydraulic system uses double-acting cylinders to convert the piston’s pressure into significant force, which supports ideal lumbar, back, and seat rest.
Hydraulic vs Pneumatic Chairs
Have you ever noticed how adjustable office chairs move up and down effortlessly? This is due to their hydraulic or pneumatic systems. Below are their differences:
- Hydraulics: Uses liquid/oil to transmit power, suitable for heavy-duty work.
- Pneumatics: Uses compressed gas to transmit power, faster and cleaner, ideal for office chairs.
Both systems have advantages and cater to different needs. A hydraulic system provides power and efficiency, while a pneumatic system offers speed and simpler maintenance.
Repairs and Maintenance
Can you fix a hydraulic chair? To access the interior cylinder, tilt the chair to its side and follow the manual to disassemble the parts. Cylinders are replaceable if needed.
Common Question: Why a Chair Might Keep Lowering
This issue is often due to a problem with the gas cylinder—a spring filled with air that controls the height adjustment.
Frequently Asked Questions
What is a Hydraulic Treatment Chair?
A hydraulic treatment chair is a piece of medical equipment designed for a comfortable, adjustable platform during various therapies or examinations.
How to Measure Gas Cylinders for Chairs
When replacing a gas cylinder, measure the new cylinder based on your seating height preferences. Gas cylinders typically have a universal diameter of around 2 inches and can raise the chair by approximately 5 inches, varying from 4 to 10 inches depending on the chair design.
In conclusion, understanding the type of hydraulic system in your chair—whether pneumatic or hydraulic—is key to proper use and maintenance.
