The oil cup adopts advanced materials and technology: the cup body is made of high-transparency PC (polycarbonate) material, allowing maintenance personnel to visually monitor oil levels in real time; the inner liner is made of corrosion-resistant PP material, compatible with various types of elevator special lubricating oil; the precision oil feeder with adjustable flow rate ensures a uniform and stable oil supply (adjustable range: 5–20 drops per hour); the standardized mounting bracket and clip design enable quick installation and replacement without additional modification to elevator components.

Step-by-Step Usage Guide for Elevator Oil Cup RL-300

To maximize the lubrication effect, service life, and operational stability of the Elevator Oil Cup RL-300, strictly follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for selection, installation, and use:

1. Professional Selection & Installation

Installation can be conducted by certified elevator technicians or professional maintenance personnel. Prior to installation, refer to the compatibility manual provided by Nanjing Zhuye Elevatorparts to confirm that the RL-300 oil cup matches the elevator’s lubrication points (guide rails, sliding shoes, etc.) and mounting dimensions. The installation steps are as follows:

Safety Preparation: Cut off the elevator’s main power supply and lock the power switch to prevent accidental power-on. Fix the elevator car at a convenient maintenance position using mechanical supports. Clean the mounting area near the lubrication point to remove dust, oil stains, and debris, ensuring a smooth and stable mounting base.
Oil Cup Installation: Fix the mounting bracket of the RL-300 oil cup to the designated position using stainless steel screws provided by Nanjing Zhuye Elevatorparts. Ensure the oil cup is installed vertically (tilt angle ≤ 5°) to guarantee stable oil flow. Snap the oil cup body into the mounting bracket, and adjust the position of the oil feeder tube to align it accurately with the elevator’s lubrication point (distance between tube mouth and lubrication point: 2–5mm).
Oil Filling & Flow Adjustment: Fill the RL-300 oil cup with special elevator lubricating oil (recommended by Nanjing Zhuye Elevatorparts, viscosity grade 32–46). Do not overfill (oil level should not exceed 80% of the cup’s capacity) to avoid oil leakage. Rotate the flow adjustment knob on the oil feeder to set the appropriate oil flow rate according to the lubrication requirements of the component (general guide rail: 8–12 drops per hour; door machine mechanism: 5–8 drops per hour).

2. Daily Operation & Routine Maintenance

Regular inspection and maintenance are essential to ensure the stable lubrication performance of the RL-300 oil cup and prevent faults such as oil shortage or oil leakage. Maintenance personnel should integrate the following checks into their daily patrol routines:

Daily Oil Level Inspection: During elevator patrols, check the oil level of the RL-300 oil cup through the transparent cup body. If the oil level is lower than 20% of the cup’s capacity, refill it with the specified lubricating oil in a timely manner. Record the oil consumption to monitor the oil supply status.
Weekly Sealing & Flow Check: Inspect the sealing performance of the oil cup’s lid and oil feeder connection. If oil leakage is found, tighten the lid or replace the sealing ring (provided by Nanjing Zhuye Elevatorparts). Recheck the oil flow rate to ensure it remains within the set range; adjust the knob if there is any deviation.
Monthly Cleaning & Inspection: Cut off the power supply and remove the RL-300 oil cup. Clean the cup body, inner liner, and oil feeder tube with a soft cloth to remove oil residues and impurities. Check for cracks, deformation, or aging of the cup body and sealing components; replace damaged parts immediately. Reinstall the oil cup, refill it with oil, and recheck the oil flow rate.

Recommended Replacement Cycle for Elevator Oil Cup RL-300

As a key lubrication component enduring long-term contact with lubricating oil, environmental erosion (humidity, dust, temperature changes), and mechanical vibration, the RL-300 oil cup has a specified service life. Timely replacement is critical to avoiding faults such as poor sealing, blocked oil feeder, or unstable oil supply—issues that may lead to insufficient lubrication of elevator components, increased friction and wear, and even serious mechanical failures affecting elevator operation safety.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, ambient temperature -10–60℃, humidity 10%–95%), the recommended replacement cycle for the RL-300 elevator oil cup is 1.5–2 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field operation data, material aging tests, and global user feedback on elevator lubrication systems.

2. Adjustments for Special Scenarios

Harsh Environments & High-Traffic Scenarios: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust industrial sites, or ultra-high-traffic locations (e.g., large airports, central shopping malls) with daily operation time ≥ 20 hours, the replacement cycle is shortened to 1 year. Harsh conditions accelerate the aging of the oil cup’s sealing components and the blockage of the oil feeder.
Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable environments (constant temperature and humidity), the replacement cycle can be extended to 2–3 years—only if Nanjing Zhuye Elevatorparts’ professional technicians conduct an inspection and confirm that the oil cup’s sealing performance, oil flow stability, and structural integrity meet the original factory standards.

3. Immediate Replacement Conditions

Replace the RL-300 elevator oil cup immediately if any of the following issues occur, regardless of its service life:

The cup body is cracked, deformed, or severely yellowed and brittle, leading to oil leakage or inability to hold oil normally.
The oil feeder is blocked and cannot be cleared after cleaning, resulting in interrupted oil supply to the lubrication point.
The sealing ring is severely aged, swollen, or damaged, causing persistent oil leakage that cannot be resolved by tightening or adjusting.
The flow adjustment knob fails, and the oil flow rate cannot be controlled within the required range, affecting normal lubrication.

In conclusion, the Elevator Oil Cup RL-300 supplied by Nanjing Zhuye Elevatorparts is a high-quality, reliably compatible lubrication component tailored for modern elevator systems. By adhering to the correct usage methods, maintenance schedules, and replacement cycles outlined above, elevator maintenance teams can effectively ensure the stable lubrication of key elevator components, reduce mechanical failures, extend the service life of the elevator, and enhance passenger ride comfort.
