  • Patent number: 12247586
    Abstract: A simple and cost-effective device to shift a structural resonance in a vertical long shaft pump is disclosed. T disclosed device comprising portion of a motor of the vertical pump by using a plurality of fasteners, and one an upper plate and a lower plate being adapted for fitment at a non-driving end or more annular plates adapted for fitment at the non-driving end portion of the motor between the upper plate and the lower. Each of the one or more annular plates comprises an annular central hole with splined grooves to engage with cooling fins of the motor. The device further comprises tie rods for fitment with flanges of a column pipe of the vertical pump using Bellville washers and bolts, and mass blocks with matching square internal threading for fitment with the tie rods to add mass at required location.

  • Patent number: 11280444
    Abstract: A stiffening device for a base frame is disclosed. The disclosed stiffening device comprises hydraulic jacks fitted with structural members of the base frame; strain gauges coupled to the structural members of the base frame, the strain gauges configured to detect deformation in the structural members of the base frame and generate first signals based on the detected deformation in the structural members; at least one signal conditioner unit coupled to the strain gauges to receive the first signals and generate second signals by performing any or a combination of amplification, filtering and conversion of the received first signals; and a hydraulic console configured to actuate at least one of the hydraulic jacks when value of received second signals is above a predefined threshold value. Upon actuation, the actuated at least one of the jacks stiffens at least one of the structural members of the base frame.
