Have you ever experienced that sinking feeling in your office chair? You're not alone. Over time, constant use can cause the pneumatic valve, responsible for adjusting the seating platform, to lose its effectiveness. However, understanding how your office chair works can easily resolve this issue. By familiarizing yourself with its mechanisms, you can address the sinking problem and restore the functionality of your chair.
Understanding the Concept of Pneumatic:
Pneumatic and hydraulic systems are commonly employed in heavy machinery to facilitate movement. Pneumatic systems utilize compressed air to generate power, while hydraulic systems use oil. By drawing in and storing air or oil in high-pressure tanks, these systems enable the transfer of power to the machinery through pipes and valves. Compared to hydraulic systems, pneumatic systems offer advantages such as lighter weight, cleaner operation, and cost-effectiveness.
Understanding the Importance of Pneumatics in Office Chairs
Office chairs are designed with clever mechanisms for easy adjustment. Instead of cumbersome manual methods, modern office chairs utilize pneumatic elements that allow effortless changes to the seating arrangement. A pneumatic office chair typically features a single-acting cylinder, which is essentially a spring filled with air. As the piston extends from the chamber, the air inside expands, resulting in the lowering of the seat. However, if your chair keeps sinking, it indicates a malfunctioning cylinder that needs attention.
Prevent Your Office Chair from Sinking with These Tips
Restoring a sinking gaming chair is indeed possible. However, before addressing the cylinder issue, it is important to ensure that the other components supporting the mechanism are functioning properly. Lubricate the lever to ensure smooth operation. As for the cylinder, there are two recommended methods to address the problem...
The PVC Pipe Technique:
To prevent your chair from sinking, follow these steps:
-
Start by moving the plastic tube away from the extendable cylinder to reveal the metal cylinder underneath.
-
Measure the width, length, and circumference of the metal cylinder.
-
Purchase a PVC pipe that matches the length of the metal cylinder. It should have the same diameter or slightly larger.
-
Use a small hacksaw to cut the PVC pipe from one opening to the other, creating a split.
-
Slide the cut PVC pipe onto the metal cylinder. If desired, you can remove the chair's wheelbase to make it easier to slide the PVC pipe without cutting it.
-
Once the PVC pipe is in place, your chair should no longer sink. Adjust the length of the pipe if needed when adjusting the chair's height.
By following these steps, you can effectively prevent your chair from sinking without the need for complicated modifications.
