进口高温零泄漏风机characteristic:

For fans used in steel plants, chemical plants and other occasions, some fans convey gases containing harmful components to human body, and some fans are used to convey pure nitrogen and other process gases. The sealing requirements for the fan are relatively high, especially at the shaft seal, due to the rotation of the main shaft, leakage is easy to occur. Usually, the method of this type of fan is to install the shaft seal behind the casing, and there is no connection between the shaft seal and the transmission case. Shaft seals include labyrinth seal, gas seal, carbon ring seal, etc. However, such seals have shortcomings such as high requirements for installation accuracy and easy wear.

进口高温零泄漏风机Principle:

The transmission part assembly for the high-temperature zero leakage fan includes the main shaft and the bearing housing. The first bearing and the second bearing are installed between the main shaft and the bearing housing. The side of the first bearing is equipped with an oil deflector ring I, and the side of the second bearing is equipped with an oil deflector ring II. The oil deflector ring I and the oil deflector ring are arranged in two opposite directions. Between the oil deflector ring I and the oil deflector ring II is a bearing housing cavity. The end of the bearing box close to the first bearing is connected with a front end cover, and the end of the bearing box close to the second bearing is connected with a rear end cover. The front end cover is provided with a first cavity on the surface close to the main shaft. The front end cover is provided with an air inlet. The first cavity is provided with a first labyrinth seal. The first labyrinth seal is fixed in the front end cover by screws. The air inlet is connected with the first labyrinth seal. The front end cover is provided with a first grease nipple, which is connected with the first cavity. The normal temperature or cold air is flushed through the inflation port, which can play a cooling role. As the gas filled is high-pressure gas, it can play a high-pressure sealing role to prevent leakage of other toxic gases. The first labyrinth seal can prevent the left gas from entering the right bearing housing. The first grease fitting is used to lubricate the first bearing. The rear end cover is provided with a second cavity on the surface close to the main shaft, a second grease nipple is arranged on the rear end cover, and the second grease nipple is connected with the second cavity. The second grease fitting is used to lubricate the second bearing.
