Wear of tunnel fan impellers and treatment methods

Wear of tunnel fan impellers and treatment methods

When the fan impeller rotates, it carries a small amount of large particles and numerous microscopic dust particles along with high-temperature, high-speed flue gas through the induced draft fan, subjecting the blades to continuous erosion.

How should tunnel fan equipment be maintained regularly?

How should tunnel fan equipment be maintained regularly?

The operating environment should be maintained in a clean state at all times; the surface of the fan must remain tidy, and there should be no debris in the air intake or exhaust ports. Dust and other contaminants within the fan and its ducts should be removed regularly.

Various Methods for Fan Noise Measurement and Existing Solutions

Various Methods for Fan Noise Measurement and Existing Solutions

There are numerous causes of noise generated by fans, and only by identifying the root cause can effective solutions be implemented. A fan is essentially a positive displacement compressor consisting of a pair of vertically meshed elliptical blades that rotate at high speeds to convey gas.

The relationship between the rotational speed of the tunnel fan and the air volume

The relationship between the rotational speed of the tunnel fan and the air volume

The air volume of a tunnel fan reflects its ventilation and cooling capacity. We understand the relationship between the rotation of the tunnel fan and the air volume: during operation, the rotation of the fan blades alters the type and quantity of airflow as well as its velocity.

Causes of elevated bearing temperatures in fans

Causes of elevated bearing temperatures in fans

Excessive bearing temperature in fans is one of the primary causes of bearing failure. The main factors contributing to elevated bearing temperatures include the following:

Basic design principles for the ventilation of tunnel fans

Basic design principles for the ventilation of tunnel fans

To enhance ventilation management within tunnels, improve ventilation quality, strengthen on-site construction safety management, and elevate standards of civilized construction practices, the following requirements apply to the installation, layout, and connection of tunnel ventilation equipment and air ducts. All tunnel entrances must comply with these specifications.
