Abstract: A centrifugal pump sealing structure is provided. In one aspect, one sealing member is provided at a position where leakage paths from a fluid compression space between a middle housing and a cover and an electric component installation space between the middle housing and a lower housing are connected. Then, the two spaces are sealed. The number of sealing members is reduced, so that the internal structure becomes simpler and the assembly of the sealing member becomes easier.

Abstract: A plant or refinery may include equipment such as condensers, regenerators, distillation columns, rotating equipment, compressors, pumps, turbines, or the like. Different operating methods may impact deterioration in equipment condition, thereby prolonging equipment life, extending production operating time, or providing other benefits. Mechanical or digital sensors may be used for monitoring equipment to determine whether problems are developing. For example, sensors may be used in conjunction with one or more system components to perform invariant mapping, monitor system operating characteristics, and/or predict pressure, volume, surges, reactor loop fouling, gas quality, or the like. An operating condition (e.g., of one or more pieces of equipment in the plant or refinery) may be adjusted to prolong equipment life or avoid equipment failure.

Abstract: A rotor for a supercharging device may include a compressor wheel and a turbine wheel. A sealing disc may be arranged between the compressor wheel and the turbine wheel. The sealing disc may include a first side interfacing with the compressor wheel and a second side interfacing with the turbine wheel. The compressor wheel and the turbine wheel may each define one of a holding contour and a counter-holding contour, which respectively interact with a corresponding one of a holding contour and a counter-holding contour defined on each of the first side and the second side of the sealing disc. The respective holding contour may correspond to the respective counter-holding contour, which may engage in one another and secure the compressor wheel, the sealing disc and the turbine wheel to one another.
