Oil Leakage Under Office Chair

Oil leakage under an office chair usually indicates a failure in the sealing system of the pneumatic rod, resulting in the leakage of hydraulic or lubricating oil. This requires prompt investigation and handling to avoid safety hazards.

Analysis of Oil Leakage Causes

The core reason for oil leakage in office chairs is the failure of the sealing system in the pneumatic rod, with common causes including:

1. Seal Aging: After prolonged use, rubber components such as seals and valves lose elasticity due to oxidation or wear, leading to a decrease in sealing performance.
2. Improper Use: Overloading (exceeding the chair's rated weight capacity), violent impacts, or frequent tilting of the chair may cause damage to the internal structure of the pneumatic rod.
3. Abnormal Oil Pressure: Excessive oil pressure inside the hydraulic rod, exceeding the capacity of the seals, triggers oil leakage.
4. Component Damage: Oil leakage from valves, loose connectors, or scratches on the rod body directly compromise the integrity of the seal.

Inspection Steps

1. Observe Oil Seepage: Record the location of oil stains, their spread range, and initial condition to preliminarily assess the severity of the oil leakage.
2. Test Lifting Function: Check if the chair lifts smoothly, noting any stuttering, weakness, or inability to lock. Functional abnormalities may accompany damage to the sealing system.
3. Re-inspect After Cleaning: Wipe oil stains from the surface of the pneumatic rod with a dry cloth and observe for new oil stains after a period of time to confirm if the leakage persists.
4. Review Usage Habits: Check for overloading, frequent tilting, or impacts on the chair, as these behaviors may accelerate seal aging or cause mechanical damage.

Handling Procedures

• Within Warranty Period: Immediately contact the official after-sales service of Deli, provide the purchase invoice, describe the oil seepage phenomenon and functional abnormalities, and schedule an on-site inspection or replacement of the pneumatic rod.
• Outside Warranty Period:
  1. Clean the oil leakage area to prevent oil stains from corroding the floor or polluting the environment.
  2. Inspect seals, valves, connectors, and other components, replacing damaged parts (matching the original factory model).
  3. If the oil pressure is too high, adjust the internal oil pressure of the hydraulic rod under the guidance of professionals to avoid secondary damage caused by self-operation.
  4. After repair, lubricate relevant components, adjust the chair's height and tilt, and test for normal functionality.

If the oil seepage is severe, the oil stains spread rapidly, or is accompanied by lifting stuttering, abnormal noises, or complete functional failure, immediately stop using the chair. Prioritize replacing the pneumatic rod or contact professional repair personnel to handle it, preventing the risk of falls due to sudden failure of the pneumatic rod.
