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?

What is the impact of temperature on reversible jet fans in pipe galleries?

What is the impact of temperature on reversible jet fans in pipe galleries? Temperature is a very important part of the environment, and for many devices, it has a significant impact on their working condition, performance, and so on. Like a fan, a high-temperature fan is a type of fan used in specific high-temperature environments. Instead, use a plastic fan. The ambient temperature should not be too high, as the material will be heated. So what is the impact of temperature on reversible jet fans in pipe galleries? Today we will provide a detailed explanation. What is the effect of temperature on reversible jet fans in pipe galleries?

How to clean and repair the reversible jet fan in the pipe gallery?

How to clean and repair the reversible jet fan in the pipe gallery? When using a reversible jet fan with a pipe gallery, it can only move forward at full speed. At the same time, in order 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. To ensure that the reversible jet fan of the pipe gallery is not allowed to be maintained 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.
