Xin Feng Mini Lesson---Common Wear Components in High-Temperature Fans

What parts are prone to wear in high-temperature fans during operation? High-temperature resistant fans represent a new generation of motors developed alongside advancements in magnetic materials, semiconductor technology, and control systems.

High-speed, vibration-free, low-noise, compact size, simple structure, energy-efficient, low electromagnetic radiation.  High-temperature resistant fans primarily utilize combined technologies of forced air cooling, oil-free water cooling, and cold plate cooling.  The cold plate is made of aluminum alloy, featuring strong thermal conductivity, no additional losses, and a simple structure.  Fans below 150 horsepower employ air self-cooling technology with a rational and aesthetically pleasing duct design.

200 horsepower and larger models employ an internal water-cooled circuit, eliminating the need for external cooling valves or additional cooling water. This cooling system ensures the high-temperature fan maintains reliability during hot summers. The external air bypass pipe inside the high-temperature fan features valves and a shroud. During production, the housing is made of carbon steel, with the interior lined with sound-absorbing material.  Air entering the high-temperature fan body flows through the inlet, ensuring safe shutdown without impact during power outages or malfunctions, while maintaining an aesthetically pleasing appearance.  Direct connection to the fan via flexible hose minimizes pressure loss and noise in the air duct.  The filter and shroud are constructed from a steel casing  with internal shroud material.

The high-temperature resistant fan features a quadrilateral or rectangular design. A filter is installed at the air inlet, while an acoustic exhaust silencer with excellent sound absorption is positioned between the fan's outlet and the filter to reduce noise at the airflow exit. Utilizing advanced air suspension technology, it completely eliminates mechanical friction and vibration. Strict measurements confirm that the noise level at 1 meter from the machine is less than 80 decibels.

When installing high-temperature fans, to ensure optimal ventilation equipment quality, strictly adhere to correct installation methods while paying attention to easily overlooked operational details. During installation, position the motor's adjustment screws in this operational location for convenient voltage regulation. Are parts prone to wear during high-temperature fan operation? Install the fan and control surrounding seals. If vacuum occurs, seal with polycarbonate sheets or glass adhesive. Support materials must ensure stability between the material and soil. If necessary, reinforce the corner ice beside the high-temperature fan.

Stabilize the equipment: Check the horizontal alignment of the equipment, ensuring the base is stable and the engine at the rear of the equipment is not tilted.

Therefore, when installing high-temperature fans, pay close attention to the above points to avoid installation errors. After installation, ensure that ventilation is only used during normal operation. This enhances availability and prevents abnormal interruptions.

When multiple units are in operation, some wear is inevitable.  Certain components are particularly susceptible to wear.  For high-temperature fans, two specific parts are prone to this: blades and voltage components.  This phenomenon is especially noticeable in power plants.  First, let's examine blade wear.  Blade wear varies depending on the equipment configuration.  Understanding the number of components in a high-temperature fan is also crucial. Additionally, high-pressure high-temperature fan applications: For instance, severe wear in high-temperature fans Primarily occurs at the inlet, outlet, and areas near the iron disc after exhaust. Some high-temperature fans utilize straight-diameter blades. Such blades exhibit the following wear patterns: Typically, serrated wear sections concentrate at the blade openings, gradually diminishing inward from the blade openings.

Beyond these two scenarios, certain high-temperature fans are employed in practical applications. For rear-blade designs, severe wear along the outlet line occurs near the rear disk and blade tip, with the blade tip being particularly susceptible to abrasion. Powder infiltration into blade holes can lead to issues like rotational imbalance and fan vibration. In centrifugal fans utilizing rear blades, lateral displacement near the disk often manifests as wear.

Observing spiral wear patterns: Regardless of high-temperature fan model, volute wear follows a consistent pattern. The most severe wear occurs near the volute. Typically, volute wear initiates at the volute tongue, with the most critical wear zone spanning 1/6 to 1/4 of the warm-up line.
