  • Patent number: 9841030
    Abstract: The present invention claims a vertical self-priming pump which comprises a pump body, a motor and a medium backflow blocking device, the medium backflow blocking device comprises a static ring and a moving ring which are vertically and oppositely arranged, and an elastic supporting sleeve; the moving ring is embedded on the upper surface of the impeller, the elastic supporting sleeve is fixed on the upper surface of the flow guide body, and the static ring is embedded on the lower surface of an elastic supporting ring. During normal working, the elastic supporting sleeve of the present invention in the medium backflow blocking device generates a downward deformation under the action of liquid medium pressure, thus the moving ring and the static ring closely contact with each other and block the backflow gap channel, and the pump efficiency is improved.

  • Patent number: 9835160
    Abstract: A converterless motor-driven pump system includes an off-grid prime mover, an electric power generator driven by the off-grid prime mover to generate a power output, an electric submersible pump (ESP) system, and a system controller. The ESP system includes a motor coupled to the electric power generator to receive the power output, and a pump driven by the motor to pump a fluid. The system controller includes a processor and a memory. The memory includes instructions that, when executed by the processor, cause the system controller to control the off-grid prime mover as a function of an operational parameter of the ESP system to maintain a desired operating point of the pump, and control the electric power generator to reduce the power output generated by the electric power generator while the desired operating point of the pump is maintained.

  • Patent number: 9777640
    Abstract: A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. The inlet-adjustment mechanism includes an axially elongated ring. In the open position, the radially outer surface of the ring is spaced from a tapering inner surface of the air inlet so that air can flow in an annular passage between the tapering surface and the ring. In the closed position, the ring abuts the tapering surface to close off the annular passage, whereby the effective inlet diameter is then defined by the inner diameter of the ring at its trailing edge. Movement of the inlet-adjustment mechanism from the open position to the closed position is effective to shift the compressor's surge line to lower flow rates.

  • Patent number: 9745970
    Abstract: A linear compressor employing a piezoelectric actuator operating in resonance at a frequency substantially below its natural resonant frequency, which is usually of the order of 10 kHz. Low frequency resonance operation of the actuator, of the order of 100 Hz., is achieved by incorporating the actuator and its housing with the moving compression piston, such that the moving mass is substantially increased, and by reduction of the effective piezoelectric stiffness using hydraulic amplification of the actuator displacement. Both these procedures result in a reduction of the actuator resonant frequency. The hydraulic amplification is achieved by using a hydraulic chamber with different sized pistons, linking the actuator motion with motion of the actuator housing, to which the compressor piston is attached. The high efficiency achieved and the lack of moving parts or the need for lubricating oil makes the compressor ideal for use in high reliability and high purity applications.

  • Patent number: 9719503
    Abstract: The present invention provides such pumping apparatuses that have very little deviation and high stability in pumping flow. A pumping apparatus comprises two members that are set along a longitudinal direction of a tube made of an elastic material with a relation that the space formed by grooves made in the two members holds the tube. The two members have reciprocal motion such that at least one of the two opposing members shuttles in parallel with the other opposing member and has a move-in motion such that at least one of the two opposing members vertically moves to the opposing surfaces of the other opposing member so that surrounding part of the groove thereof moves into an inner space of the groove of the other opposing member, by which motion the liquid in the tube is discharged from the tube by the deformation of tube cross sectional shape.

  • Patent number: 9695807
    Abstract: The micropump includes continuous cylindrical separating pipes having at least two alternating stages of pipes of small radius and large radius connected in succession. Each pipe of a large radius has one end as a hot zone, and the opposite end as a cold zone. The pipes alternate straight pipes with a large radius and U-shaped curved pipes with a small radius. The relationship of the large radius (R) to the small radius (r) is in a range of R/r=2 to 10000, while the relationship of the temperature (T2) of a hot zone to the temperature (T1) of a cold zone is T2/T1=1.1 to 3.0. The length and radius measurements of a straight pipe and a U-shaped pipe ensure a given change in temperature of the gas from the temperature of the hot zone to the temperature of the cold zone.
