Problems solved by technology

The wind sensor can judge the wind blown by the blower through the rotation angle of the wind flag, and then judge whether the blower is working normally. When dust and other impurities enter the gap between the central shaft of the wind sensor and the central shaft sleeve, it will hinder the free rotation of the central shaft, resulting in If the rotation angle of the wind flag is not judged accurately, it is impossible to judge whether the blower is working normally

Abstract

The invention discloses a magnetic fluid dust-proofing and sealing method for a wind sensor. A central shaft sleeve (4) is mounted in a shell (5) and is welded at the bottom of the shell. A pole screw (8) is connected to the shell (5) in a threaded manner. A positioning screw (10) and a positioning screw (11) are mounted on the shell (5). A magnetic core (7) is mounted in a sway magnetic column (6). A wind flag (9) is welded in a central shaft (1) mounted in a rubber magnet (2), the central shaft sleeve (4) and the sway magnetic column (6), and is fixed through a tightening screw. Magnetic fluid (3) is injected into a gap between the rubber magnet (2) and the central shaft sleeve (4). The magnetic fluid (3) is absorbed in the gap between the rubber magnet (2) and the central shaft sleeve (4) owing to the magnetic field generated by the rubber magnet (2) to prevent outside impurities from entering a gap between the central shaft (1) and the central shaft sleeve (4), so that the purposes of dust proofing and sealing are achieved.

Description

technical field [0001] The invention relates to a magnetic liquid dust-proof sealing method for a wind sensor, which belongs to the field of mechanical engineering sealing. Background technique [0002] The wind sensor is installed in the air duct of the blower. When the blower is working normally, it can cool a certain military radar, so that the radar can operate normally. The wind sensor can judge the wind blown by the blower through the rotation angle of the wind flag, and then judge whether the blower is working normally. When dust and other impurities enter the gap between the central shaft of the wind sensor and the central shaft sleeve, it will hinder the free rotation of the central shaft, resulting in If the rotation angle of the wind flag is not judged accurately, it is impossible to judge whether the blower is working normally. Therefore, the dust sealing of the wind sensor is very important. The magnetic liquid seal is a new type of sealing method. Its main fe...
