If the volume is large enough, the stirring speed should be low, and there should be at least three fixed points on the stirring shaft.

Personally, I think there is a flaw in the mixing design or installation. The design of such a large volume mixing is inherently difficult. First check the installation quality, and then negotiate with the designer to find the problem.

The mixer is not powerful enough and the support is not strong enough.

Personally I think it might be: 1. Problems with the installation and fixation of the mixer. 2. The mixer is not installed perpendicular to the horizontal direction. 3. There is a problem with the stirring speed. :lol

Personally, I think there are two options that you can try.: 1. Problems with current mixing are basically caused by poor installation quality. The centers of the motor main shaft and the mixing shaft are not aligned, or the vertical accuracy of the installation is not high. These two reasons are the main reasons why the motor is easily damaged and the shaft is broken. Therefore, it is necessary to recalibrate the coincidence degree of the center lines of the motor and the stirring shaft and ensure the verticality of the motor and the stirring shaft. 2. Why does such a large jar need to be stirred? It's very unscientific. How powerful is the motor when stirring so much liquid? Think of a way for you: Install two low-lift, high-flow pumps to circulate the liquid in the tank. The pump inlet is at the bottom of the tank, and the pump outlet pipe is a little above the normal page or slightly below the liquid level. The mixing effect is achieved through the impact and turbulence of the fluid. The power consumption and effect are definitely better than stirring!

When stirring such a large storage tank, the recommended speed is 10 rpm or lower. The speed is high and the vibration is large. The fiberglass material will aggravate the vibration. If conditions permit, the stirring should be fixed separately, not on the fiberglass tank. It is recommended that the specific speed depends on the vibration situation. After the speed is determined, check the strength.

You should consider the following aspects: 1. What is the viscosity of the medium at the operating temperature and whether the type of agitator selected is reasonable? ； 2. Whether the fixed points are sufficient during the installation of the mixer and whether the support strength meets the requirements. ； 3. Is the stirring speed too fast? 4. Check whether resonance occurs during the operation of the mixer. 5. The tank is large in size, so consider whether a combination of multiple mixers is needed.

The power of the stirring device is not enough. The strength of the stirring shaft is not enough to cause the situation you mentioned. The form of the stirring paddle also has a great impact on it.

Can compressed air be introduced to achieve a stirring effect? P.S.: Is it necessary for the intermediate storage tank (mixing tank) to be so large?

What the person on the 6th floor said is correct! Generally, I use hydraulic stirring for 30 cubic meters. The liquid circulation pipe enters at the liquid level in the tank, tangentially to the tank wall; or a circumferential distributor is made 50 cm below the liquid level to make the liquid form local turbulence to achieve the purpose of mixing! :victory: :handshake

1. The balance was not adjusted during installation.； 2. The medium resistance is too large, increase the motor power. ； 3. Increase the number of stirring paddles, generally more than 3 pieces.

Perhaps the design of the shaft is not strong enough! ! !
