Centrifuge impeller (urgent urgent urgent)

For this issue, one would need to consult the equipment manufacturer. Impeller rotors are generally not allowed to accumulate scale; once such accumulation occurs, it can cause vibration in the rotor. When the vibration level exceeds the allowable limit, an automatic alarm is triggered and the equipment shuts down. The vibration values provided by the equipment manufacturers are primarily used as a reference. This cannot be measured by the amount of weight that can accumulate as scale. This is still related to the degree of uniformity. The calculation formula seems too academic. In case of on-site operation, the detection of vibration indicates a possible buildup of scale; it is acceptable to maintain normal production as long as the vibration level remains within the set range for the equipment, but it is not permissible if it exceeds that range. Then the machine has to be stopped for cleaning. The above is an understanding of this question from the user's perspective. If it involves design, you should consult a teacher; there are levels 1 and 2, as well as other levels 3 that need to be taken into consideration. Just offering my thoughts to stimulate further discussion – I’m curious to hear how the other teachers would explain it. Let’s sit down and talk about it;P

I agree with what was said on the second floor: if the scaling on the impeller is uniform, it has little impact on vibration, but it still affects the pumping capacity and mechanical efficiency. There’s no need to worry about whether it meets certain standards; it should be cleaned promptly!

First, find out the cause of the scaling – three parts are production and seven parts are the equipment.

If dust accumulates on the impeller while it is in operation, the accumulation will be relatively even, and the rotor’s vibration levels will not change significantly. However, when the unit stops operating or is subjected to external vibrations, a portion of the dust on the impeller may suddenly fall off. This will trigger a vibration level alarm upon restart; in such cases, it is necessary to clean the impeller or remove it and perform dynamic balancing again. As for the method for calculating rotor dynamic balance, it is necessary to consult the original manufacturer’s design department; the using department cannot find out this information. As for the weight of the largest attachments on the impeller, it also needs to be determined by the original manufacturer’s design department.

Just remove the dirt, find the cause, and fix it. Perform another level 1 maintenance on the pump
