What is the troubleshooting of explosion-proof and anti-corrosion fans?


1. The common coupling pointing method is uncomfortable for high temperature electric fans.

Explosion-proof and anti-corrosion fanGenerally, when adjusting the coupling between the motor of the anti-corrosion centrifugal fan, the fluid coupling and the high temperature electric fan, two key methods are used: this method is to accurately measure the axial and diameter of the feeler gauge according to the auxiliary tablet computer. In this way, when the half couplings of two anti-corrosion centrifugal fans do not touch each other, use a dial indicator to fix it and rotate the axial and inner holes of the half couplings to bounce.

2. The effect of lotus coupling must also be properly measured for the harm of the swelling difference.

Explosion-proof and anti-corrosion fanAfter applying the described method to the orientation of the coupling of the anti-corrosion centrifugal fan and the parallelism is controlled within 0.05 mm, people often incorrectly think that it is the idealized situation of coupling. The key to this kind of misunderstanding is that it has not paid special attention to the hazards of the difference in the expansion of the electric fan, fluid coupling and motor axis under hot and cold conditions. Some people have paid special attention to the hazards of the swelling difference, but incorrectly believe that the temperature of the fan will be higher when the fan is running. Therefore, the cold axis should be low, and the high-temperature natural environment where it is located is incorrectly used as the basis for measuring high thermal deformation.

3. When installing the bearing end cover of the anti-corrosion centrifugal fan, it can safely avoid the installation error of the fixed end and the random end.

Explosion-proof and anti-corrosion fanIn order to incorporate the thermal deformation caused by the high-temperature natural environment of the anti-corrosion centrifugal fan shaft, the manufacturer designed a non-precisely positioned rolling bearing at the end of the anti-corrosion centrifugal fan. Accurate positioning The rolling bearing must be rigorously and accurately positioned during the entire installation process, and the swelling side of the rolling bearing is not restricted. If it is installed and exchanged, the shaft's arbitrarily swelling and closing will be restricted, which will cause safety accidents of machinery and equipment. For this reason, when installing anti-corrosion centrifugal fans, the most commonly used errors to avoid are to fix the fixed end and the optional bearing end cover.
