Reasons for the vertical shielded pump operating above its rated current
Thread Content
Hello everyone: After routine maintenance of the vertical shielded pumps produced by Dalian Haimitek, including shaft alignment and dynamic balancing, these pumps were started up. Once they reached their normal flow rate, however, an excess current was observed. Please help analyze the reasons for this. Thank you
Installation requires specific clearance requirements; equipment assembly involves not only the dynamic balancing and alignment of the rotor, but also clearance requirements for various related components. Regarding alignment, it must also comply with the requirements specified in the equipment manual. Additionally, it is also necessary to look into the process media. Factors such as the viscosity, temperature, and impurity content of the liquid medium are provided for reference.
Could some expert provide the clearance values that affect installation? The manufacturer hasn’t provided them. Thank you
Since it’s a routine maintenance task, there shouldn’t be any overcurrent; there must still be some problem that hasn’t been detected. The maintenance personnel just think they are doing things correctly
