Galvanizing process of steel expander

Galvanizing process of steel expander
By test fitting the rotor on the steel expander body and pushing the rotor to one side, we can measure the maximum gap between the industry of the steel expander and the toilet part of the steel expander (the maximum axial movement of the rotor when the steel expander is normal is between 0.13-0.15, adjust it to 0.3-0.5mm. This gap range is conducive to the formation of the liquid film between the gaps, reducing the friction between the two parts of the steel expander Friction between the vice, and at the same time reduce the impact strength when suffering from the impulse.
 
Before the test run, the steel telescope should try the motor steering alone to ensure that the steering is consistent with the sign steering of the steel telescope, and then pan the coupling by hand to see if the operation is flexible. If the disk is not moving or there is abnormal sound, it should be checked in time. First check whether the coupling is level and whether the lubricant is suitable. Check while disc moving, if the problem still exists, we should dismantle the steel telescope to check and clean the foreign matter. Before the steel telescope starts, the steel telescope shell is filled with being transported; after starting, the steel telescope is driven by the shaft to rotate at high speed, and the one between the blades must also rotate with it. Under the action of centrifugal force, it is thrown to the outer edge from the center of the steel expander and gains energy, and leaves the outer edge of the steel expander at high speed to enter the worm-shaped steel expander shell.
 
In the pipeline, it decelerates due to the gradual expansion of the flow channel, and transforms part of the kinetic energy into static pressure energy, and then flows into the discharge pipeline at a higher pressure and is sent to the needed place. When flowing from the center of the steel expander to the outer edge, a certain vacuum is formed in the center of the steel expander, which is continuously pressed into the steel expander because the pressure above the liquid level of the storage tank is greater than the pressure at the entrance of the steel expander. It follows that as long as the steel telescope keeps rotating, it will keep being sucked in and out.
