Elevator Oil Cup 130*120*35mm: Reliable Lubrication Supply Core from Nanjing Zhuye Elevatorparts

Step-by-Step Usage Guide for Elevator Oil Cup 130*120*35mm

1. Professional Installation & Oil Filling

• Safety Preparation: Cut off the elevator’s main power supply and hang a “Maintenance in Progress—Do Not Power On” sign at the power switch. Fix the elevator car to a safe position using a safety clamp. Locate the lubrication points (e.g., guide rail joints, door mechanism bearings) and the corresponding oil cup mounting positions, then clean the area to remove dust, oil stains, and debris.
• Oil Cup Installation: Fix the 130*120*35mm oil cup to the mounting bracket using high-strength screws provided by Nanjing Zhuye Elevatorparts. Ensure the oil cup is installed horizontally (tilt angle ≤ 2°) to avoid uneven oil supply. Connect the oil outlet pipe of the cup to the elevator’s lubrication point interface, and use a sealing ring to wrap the connection to prevent oil leakage. Ensure the oil pipe is neatly arranged without kinking or pressing.
• Oil Filling & Adjustment: Open the oil cup’s sealed cover and fill it with special elevator lubricating oil (recommended by Nanjing Zhuye Elevatorparts, such as ISO VG 32 or VG 46). The oil level should be between the “MAX” and “MIN” scale lines (about 70%–80% of the total capacity, avoiding overfilling to prevent overflow). Adjust the stainless steel oil control valve: for guide rails, set the oil supply rate to 1–2 drops/min; for door mechanisms, set it to 2–3 drops/min. After adjustment, close the sealed cover tightly.
• Post-Installation Testing: Restore the power supply and operate the elevator to run up and down repeatedly. Observe the oil cup for leakage (check the cup body, oil pipe connections, and lubrication points). Verify that the lubrication points are properly lubricated (no dry friction noise) and that the oil level in the cup decreases steadily within a reasonable range. If there is oil leakage or insufficient oil supply, recheck the installation and valve adjustment immediately.

2. Daily Operation & Routine Inspection

• Daily Visual Inspection: Check the external state of the 130*120*35mm oil cup through the transparent cup body. Ensure the oil level is above the “MIN” scale line; the cup body is free of cracks, deformation, or oil stains (indicating leakage); the sealed cover is tightly closed; the oil pipe is intact with no kinking.
• Weekly Functional Check: Observe the oil supply rate of the control valve to confirm it remains within the set range. Check the lubrication points for dry friction, abnormal noise, or excessive oil accumulation (indicating excessive oil supply). Wipe the oil cup’s surface and oil pipe with a dry cloth to remove dust and oil stains, and ensure the transparent cup body is clearly visible for oil level observation.
• Monthly Parameter Monitoring: Refill the oil cup with lubricating oil according to the oil level (ensure it is between “MAX” and “MIN”). Check the oil pipe connections and sealing rings for aging or damage—replace the sealing ring if there is slight leakage. For oil cups installed in humid or dusty environments, check the cup body for fogging or impurity accumulation.

3. Regular Maintenance Schedule

• Quarterly Maintenance: Disconnect the power supply, remove the oil cup from the mounting bracket, and empty the remaining oil. Clean the cup body, oil outlet pipe, and control valve with a professional cleaner (provided by Nanjing Zhuye Elevatorparts) to remove oil sludge and impurities. Check the control valve for blockage or inflexible adjustment—disassemble and clean it if necessary, then reassemble.
• Semi-Annual Performance Test: Conduct a comprehensive performance test, including oil supply stability, leakage resistance, and valve adjustment accuracy. Use a measuring cylinder to collect the oil output within 1 hour and verify it matches the set rate (error ≤ 10%). Replace the sealed cover gasket with a genuine one provided by Nanjing Zhuye Elevatorparts to ensure sealing performance. For elevators in harsh environments (high humidity, high dust), increase the test frequency.
• Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Inspect the oil cup’s PC body for aging (such as yellowing or brittleness) and the stainless steel valve for corrosion. Replace the oil pipe if it is hardened or cracked. Conduct a full-range calibration of the oil supply system to ensure the oil cup and lubrication points work in sync.

Recommended Replacement Cycle for Elevator Oil Cup 130*120*35mm

1. Standard Replacement Cycle

2. Adjustments for Special Scenarios

• Harsh Environments: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or elevators with frequent high-load operation (resulting in frequent oil refill), the replacement cycle should be shortened to 2–3 years. Harsh conditions accelerate the aging of the PC cup body, corrosion of the stainless steel valve, and damage to the sealing gasket, significantly reducing the oil cup’s reliability.
• Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and clean, stable environments, the replacement cycle can be extended to 4–5 years—only if Nanjing Zhuye’s professional inspection confirms that the cup body, valve, and sealing performance are all intact.

3. Immediate Replacement Conditions

• The cup body is severely cracked, yellowed, or brittle, leading to oil leakage that cannot be repaired by replacing the sealing gasket.
• The oil control valve is stuck, blocked, or severely corroded, and cannot adjust the oil supply rate or ensure stable oil supply even after maintenance.
• The oil cup’s mounting structure is damaged, making it impossible to fix firmly; or the oil outlet pipe is hardened and cracked, leading to frequent oil leakage.
• The transparent cup body is fogged or covered with stubborn oil sludge, making it impossible to observe the oil level clearly, and cleaning fails to restore visibility.
