Rotary support forged fittings are commonly used components in industrial equipment support. Their main function is to support the weight of the equipment and provide rotational support. Due to their long-term exposure to high loads, corrosion, and high-temperature environments, failures can occur easily. This article will explore the causes of failures and preventive measures for rotary support forged fittings.
I. Causes of failures
- Corrosion: Rotary support forged fittings are often exposed to a damp and corrosive environment. Without proper coating protection or regular cleaning, material corrosion can occur, resulting in decreased material strength and increased risk of fracture.
- Fatigue: Rotary support forged fittings operate under high loads for extended periods and are frequently subject to shocks and vibrations, leading to material fatigue and reduced bearing capacity, which can cause cracks or failures.
- Incorrect installation: Improper installation and adjustment of rotary support forged fittings can reduce their bearing capacity, resulting in wobbling or collision during use.
II. Preventive measures
- Coating protection: Rotary support forged fittings with thicker protective coatings should be used to prevent corrosion and dissolution. Coatings such as anti-corrosion coating, silicone rubber, polyurethane, and polyester resins can be used. The coating status should be checked regularly, and any necessary replacements should be made in a timely manner.
- Fatigue detection: Non-destructive testing techniques such as ultrasonic testing and radiographic inspection can be used to detect fatigue damage in rotary support forged fittings, enabling identification and replacement of severely damaged components.
- Proper installation: Ensuring the correct installation of rotary support forged fittings and following the manufacturer’s instructions for adjustment and calibration are key. Equipment specifications and guidelines must be adhered to and routine maintenance performed.
- Material selection: Choosing high-strength, wear-resistant, and tough materials for rotary support forged fittings can improve their bearing capacity and long-term service life.
In summary, rotary support forged fittings are a critical industrial equipment component, and their performance and service life directly impact equipment operation and safety. Regular inspection, proper installation, and selecting high-quality materials are necessary measures for maintaining part stability and reliability.
