The present invention relates to a cooling fan drive shaft device for a refinery transfer line, and more particularly, to a refinery transfer line that cools the heat generated when transferring refined refined oil through a transfer pipe so that the temperature of the transfer tube can be maintained uniformly. It relates to a cooling fan drive shaft device.

In general, when refining crude oil in a crude oil refining process, it is evaporated by putting crude oil in a heating furnace and heating it. Since the various components contained in crude oil have different boiling points, each component can be separated.

In other words, since LPG is in a gaseous state at room temperature, it can be separated easily. components can be separated.

And, as described above, different components are separated by the difference in boiling point (boiling point) through the distillation column, and in this separation process, a large amount of air bubbles are generated, so air bubbles must be removed, and in order to separate each component, It is important to keep the temperature constant.

A device that maintains such a constant temperature is a cooling system (air-cooled cooling method), which injects air into the control unit provided on the upper portion of the rotating shaft of the rotating cooling fan (FAN) to blow the blades of the cooling fan in the pipe. By controlling the angle of the cooling fan, the amount of air supplied by the cooling fan is automatically adjusted. Due to the adjusted air amount, the temperature is maintained at a constant level along with the removal of bubbles in the oil classified by type in the distillation column, allowing each component to be stably controlled. separate
