Installation issues of stirrers in fiberglass-reinforced plastic tanks
Thread Content
A stirrer needs to be installed in the fiberglass-reinforced plastic tank; the reduction gearbox is not placed directly on the tank – instead, a steel platform is built above it. How can the problem of vibration of the stirring shaft be resolved? Does anyone with experience have any relevant insights?
Send a structure diagram to take a look. The support point of the reducer should be on the foundation.
Increase the diameter of the stirring shaft, reduce the height of the platform, and add stabilizing flanges to the tank
How is the stabilizing flange added? I would like to ask for advice
When installing a mixer in a fiberglass-reinforced plastic tank, it cannot be mounted directly on the tank; instead, a separate platform must be created. It is necessary to ensure that this platform is level. Additionally, since it is not possible to install a shaft for positioning the mixer at the bottom, shaking will occur, which can lead to damage and failure of the mechanical seal. This issue can be addressed by reducing the diameter of the mixer blades, thereby minimizing the amount of shaking.
Thank you. This device doesn’t require sealing; it’s sufficient to create a water seal groove at the mixing port. The main concern is actually the issue of vibration
There will be no problem without a mechanical seal. There will be no bouncing, as long as the platform is strong enough and firmly welded to the foundation ； Shaking is inevitable; it’s just a matter of the degree of shaking.
Reduce the stirring speed; the reducer bracket should not be installed directly on the fiberglass tank
Reducing the diameter of the stirrer blade and shortening the length of the stirring shaft can both help reduce the problem of vibration; of course, reducing the speed is another option, as well as adding a support at the bottom of the shaft. Fix the upper frame and measure the runout value under no-load conditions; once the requirements are met, there should be no major issues. The runout of a regular shaft is generally 0.5 mm/m.
