Common Malfunctions in Stainless Steel Industrial Fans During Operation

Common Malfunctions in Stainless Steel Industrial Fans During OperationIn most cases, stainless steel industrial fans frequently experience malfunctions during operation. These malfunctions not only reduce the fans’ efficiency but also cause a certain degree of damage to the equipment. One reason is that users make mistakes when selecting the right model; different models yield different results. If a fan is used in an unsuitable application, malfunctions are inevitable. Stainless steel industrial fans are categorized into steel powder fans, fiberglass-reinforced plastic (FRP) fans, plastic fans, PP fans, PVC fans, aluminum fans, and stainless steel fans, with various types available across different sectors. These represent the general categories of stainless steel industrial fans. Different types of stainless steel industrial fans present distinct operational issues, and their solutions vary significantly. One common issue with stainless steel industrial fans is blade cracking and damage, which can occur in both stainless steel industrial fans and induction draft fans. In recent years, several rotor failures have occurred at large power plants. Accidents such as rotor imbalance and vibration—which can even render the propeller uncontrollable—are serious; severe motor defects, such as overcurrent, can cause the motor to burn out; and oil leaks from the oil station, along with unstable oil pressure regulation, can affect the fan’s operational performance and threaten its safety. Wear and tear in stainless steel industrial fans is also a common occurrence. This primarily affects stainless steel industrial fans, which suffer wear due to insufficient power supply or electrical failures. This is a frequent failure mode in draft fans at coal-fired power plants. If a fan is in any of the above conditions, the power supply must first be cut off to stop the fan and confirm whether it has been idle for an extended period. As a result, the amplitude of air pressure pulsations increases significantly, leading to blade resonance damage; The main unit itself is sound, and the initial design is sound; however, issues such as improper installation, an unbalanced shaft, or poor connections—along with hidden hazards that develop over time—can cause severe fan vibration, which can easily damage bearings and couplings. If these methods fail to resolve the issues with the stainless steel industrial fan, it is now necessary to examine the type of fan. Are these problems due to an incorrect selection? Once the cause of the problem has been identified, a solution must be found immediately for the stainless steel industrial fan.
