Cooling fans play a critical role in many electronic devices and industrial applications, directly affecting the operational stability and lifespan of the equipment. To ensure the efficiency and reliability of every fan, Ruiapple Electric implements rigorous functional testing and precise oil application during the production process. This not only ensures compliance with industry standards but also guarantees high-quality cooling solutions for our customers.

1. Functional Testing of Cooling Fans

Functional testing is a crucial quality control step during fan production. At Anpu Electric, we conduct two rounds of testing, one before and one after oil application, with different focus areas at each stage to ensure compliance with stringent standards.

• Pre-Oiling Testing:
  After the fan’s basic assembly, it undergoes a comprehensive first-round test. This stage primarily assesses the fan's basic functionality and preliminary performance. Key tests include:

  • Startup Test: Ensures the fan starts smoothly without stalling or irregularities.
  • Speed Test: Measures the fan’s speed to ensure it meets design specifications and runs stably under different voltages or loads.
  • Current Test: Checks the fan's operational current for stability, which is crucial for long-term performance, preventing overloads caused by current fluctuations.
  • Vibration Test: Detects any imbalance in the fan blades or bearings using a specialized balancer. This helps correct vibration issues that may arise during operation.

• Post-Oiling Testing:
  After oil application and the installation of seals, the fan undergoes a second round of testing. This test focuses on fan performance after lubrication, with an emphasis on noise levels, long-term stability, and the effectiveness of the oiling process.

2. The Oil Application Process

Oil application is a vital step in the manufacturing of cooling fans. Proper lubrication of the bearings is essential for ensuring smooth and stable operation over time, particularly during high-speed rotations. Ruiapple Electric employs micro-precision oil application techniques to ensure each fan receives the correct amount of lubricant.

• Oil Quantity Control:
  Different fan models require varying amounts of lubrication. Ruiapple Electric uses advanced instruments to precisely control the amount of oil applied to each fan, ensuring neither over-lubrication nor under-lubrication, both of which can affect performance.

• Lubricant Selection:
  We use high-quality, high-temperature resistant lubricants that are suitable for extended operation in various environments. These oils not only reduce bearing wear but also minimize operational noise.

• Sealing Process:
  After oiling, the fans undergo a sealing process to prevent leakage of the lubricant under high temperature or high-speed conditions, thereby extending the fan's lifespan.
