Abstract

PURPOSE: To prevent the corrosion of bearing, winding, etc., by interrupting the invasion of gas, steam, etc., into fan directly connected to a closed type motor provided in gas current by connecting the inside of motor with the outside of the cylinder casing.
CONSTITUTION: When the closed type motor 2 for the ventilating fan 1 is used in the current of gas for exhausting steam-rich gas, gas, steam, etc., are inhaled into the inside of motor with the start-up and stopping of the motor 2 and therefore the bearing and winding of the motor 2 are often eroded. Thus, in order to prevent the inhalation of harmful gas, steam, etc. into the motor 2 during start-up and stopping operations, the rubber tube 5 is provided to connect the inside 3 of the motor with the cylinder casing 4, through which harmless air, etc., is introduced into the inside 3 of motor.
