6000V centrifugal pump direct start with voltage fluctuations
Thread Content
I would like to ask if anyone has experience with directly starting a 6000V centrifugal pump on-site when there are voltage fluctuations in the power supply Could you share it? In the event of a power fluctuation emergency, starting a 6000V centrifugal pump, whether it is the main pump or the backup pump, is somewhat slow following standard procedures, and the plant may even be forced to shut down. If the main pump is started immediately after tripping, there is a risk of burning out the pump due to excessive current. In such a situation, what do friends do?
Should important power facilities have dual power supply?
There’s nothing that can be done about it. Due to electrical protection considerations, once a trip occurs, a relay reset operation is required; otherwise, immediate restart cannot be achieved. The auxiliary lubrication system interlocks are the same as well. For reference.
The necessary steps cannot be omitted, such as checking whether the mechanical seal system is operating properly and whether the cooling system is functioning correctly, as well as determining whether the material inside the centrifugal pump has solidified/crystallized. Other than that, it can be started directly on site
Power surges often cause the electrical components in control cabinets to operate, leading to shutdowns; a control system can be powered by a UPS to prevent equipment shutdowns due to power surges.
