What should the upconversion pump value be on DCS?
During normal production, our company’s electrical maintenance department requires that the level not remain below 5% for long periods; we generally require it to be above 10%.
This should be determined based on the process conditions; in principle, it cannot operate at a low current level for an extended period of time.
In principle, if the motor’s efficiency remains below 30% over the long term, considering the installation of a cutting impeller is an option; if it is between 30% and 70%, up-conversion should be considered. Above 70, basically no adjustment is needed; these are guidelines for energy savings. If cutting has already taken place, it is necessary to consider the parameters required for the operation; if these parameters affect the operation, it is needed to switch back to the power frequency.
There should be a rule; it probably can’t be less than 10%
10%, and how long can it not exceed that limit?
It is variable-frequency; how does it need to be controlled and adjusted?
A 10% value means that the efficiency might be a bit low; in fact, it would be advisable to conduct further tests to determine whether the process is sufficient. If it is sufficient, then one can consider following the aforementioned principles to see if it’s possible to machine the impeller.
Not less than 10%, 50HZ
