  • Patent number: 9719515
    Abstract: A pump for pumping liquids containing entrained solids. The pump includes a volute surrounding an impeller comprising vanes that are self-cleaning. The outer surfaces of the vanes are coplanar and define a first plane and have a leading edge. The volute includes a planar mating surface defining a second plane parallel to the first plane of the rotary impeller. The planar mating surface is proximate to the outer surfaces of the vanes and includes a plurality of channels extending radially from the inner perimeter to the outer perimeter thereof. Each channel includes a forward edge in the direction of impeller rotation. The channels are oriented such that when the impeller is rotated within the volute, for any vane, the leading edge of the vane traverses each channel progressively from the inner end of the channel to the outer end of the channel.

  • Patent number: 9719366
    Abstract: Systems and methods for blade health monitoring are provided. According to one embodiment of the disclosure, a system may include a feature extraction module and an anomaly detection module in communication with the extraction module. The feature extraction module may be configured to continuously receive blade passing signal data associated with clearance of a blade and pre-process the blade passing signal data. Blade clearance feature data may be extracted from the blade passing signal data prior to transmission to the anomaly detection module. The anomaly detection module may be configured to normalize the blade clearance feature data received from the extraction module, analyze the blade clearance feature data to detect a shift in the clearance of the blade, and determine an abnormality of the blade based on the shift exceeding a predetermined shift threshold.

  • Patent number: 9702365
    Abstract: The invention relates to a method and control system to control the speed of a centrifugal compressor operating within a vacuum pressure swing adsorption process to avoid an operation at which surge can occur and directly driven by an electric motor that is in turn controlled by a variable frequency drive. The claimed method determines the optimal speed for operation of the compressor along a peak efficiency operating line of a compressor map thereof. Speed of the compressor is adjusted by a feed back speed multiplier when the flow or other parameter referable to flow through the compressor is below a minimum and a feed forward multiplier during evacuation and evacuation with purge steps that multiplies the feed back multiplier to increase speed of the compressor and thereby avoid surge.
