What are the requirements for the operating environment of reversible jet fans in pipe galleries?

What are the requirements for the operating environment of reversible jet fans in pipe galleries? Reversible jet fan for pipe gallery is a ventilation equipment used in tunnels. In some northern regions of China, the temperature inside tunnels is relatively low, especially at night, and the temperature drops rapidly. The low temperature environment can cause the tunnel fan blades to freeze, load changes, structural performance changes, and other adverse conditions. How can the reversible jet fan in the pipe gallery be improved for use in low-temperature environments?

The steel used for the impeller of the reversible jet fan in the low-temperature dedicated pipe gallery is relatively hard. In special circumstances, the raw materials of various components of a fan have different definitions, such as blades, gearboxes, circuit boards, and other components. The heating element device is used in combination with an anemometer that can be heated in certain environments. When the temperature reaches a certain low point, various heating elements will work to keep the reversible jet fan running in the pipe gallery, and the related flow load will not change.

With the maturity of reversible jet fan technology in pipe galleries, reversible jet fans can be applied to tunnels in various environments.When using a tunnel fan, it can only move forward at full speed. At the same time, to ensure sufficient power and stable voltage, the power supply line is a dedicated line and temporary lines should not be used for a long time. During the operation of the reversible jet fan in the pipe gallery, it was found that the fan had abnormal sound, severe heating, charged casing, tripped switch, and could not be started. The inspection should be stopped immediately. Ensure that the reversible jet fan in the pipe gallery is not allowed to be repaired during operation and use. After maintenance, debugging and inspection should be carried out for about 5 minutes to confirm that there are no abnormal phenomena before starting operation.

To ensure good lubrication of the reversible jet fan in the pipe gallery during operation, the refueling time should not be less than 1000 hours each time. Sealed bearings and motor bearings are strictly prohibited from operating without oil. When using a reversible jet fan in a pipe gallery, it is necessary to maintain and clean the fan properly. Regularly clean and inspect the fan to ensure its proper operation. When not in use, please place it in a dry and clean place to prevent the fan from being damaged by moisture. The reversible jet fan in the pipe gallery should be stored in a dry environment to prevent the motor from getting damp. When stored outdoors, rainproof measures should be taken. During storage and handling, avoid collisions with the machine caused by wind to prevent damage to the fan.
The reversible jet fan in the pipe gallery has the characteristics of high efficiency, obvious energy-saving effect, low noise, and long air supply distance. It is suitable for high-pressure ventilation in places such as metallurgy, nonferrous metals, gold, chemical industry, ships, ceramics, etc. Ensure that the working environment of the reversible jet fan in the pipe gallery is clean and tidy, with a clean surface and no impurities at the inlet and outlet.

Regularly clean the dust and other impurities on the fan and pipeline. Regularly inspect the lubrication system and clean the oil filter. Regularly check whether the oil is cloudy, mixed with water or other pollutants, and has deteriorated. If the situation worsens, please change the oil daily and check the normal drip nozzle of the tunnel fan. For example, remove the dirty dropper and clean the adjusting screw.
