  • Publication number: 20190017512
    Abstract: A multi-pump control system includes a control module, a processing module, a communication interface, and a storage module. The control module runs n different subsets of i pumps of a multi-pump system including N pumps during n different configuration cycles at a speed ?j, wherein N?2, 2?n?2N?1 and 1?i?N. Each configuration cycle j?{1, . . . , n} is associated with a subset j?{1, . . . , n} and a speed ?j. The communication interface receives signals indicative of operational parameters from each subset j during the associated configuration cycle j. The processing module determines an approximated pump characteristic ?p=f(q, ?j) based on the received signals for each subset j and under an assumption that the i pumps of each subset j share the same part q/i of a reference flow q. The storage module stores the approximated pump characteristic ?p=f(q, ?j) or parameters indicative thereof.

    Abstract: A centrifugal blower includes a stator housing. The stator housing includes a radial contact surface which makes contact with a casing in a radial direction, a circumferential contact surface which makes contact with the casing in a circumferential direction, and an axial contact surface which makes contact with the casing in an axial direction. With such configuration, it is possible to reduce the vibration of the blower by increasing a contact area between the casing and the stator housing. Further, the stator housing includes a heat dissipating surface. As a result, it is possible to efficiently dissipate the heat, which is generated from the stator, from the heat dissipating surface of the stator housing to the gas existing within the wind tunnel.

  • Publication number: 20190017547
    Abstract: A circumferential seal assembly capable of dividing a gas into separate flow paths before communication between a rotatable runner and a pair of seal rings is presented. The assembly includes an annular seal housing, a rotatable runner, a pair of annular seal rings, and a plurality of groove structures. Each groove structure separates a source flow communicated into a feed groove so that a portion enters at least two grooves to form a longitudinal flow therein. Each groove includes at least two adjoining steps defined by base walls. The base walls are arranged along the groove to decrease depthwise opposite to rotation of the rotatable runner. Two adjoining base walls are disposed about a base shoulder. Each base shoulder locally redirects the longitudinal flow to form an outward radial flow in the direction of one annular seal ring. The base walls are bounded by and intersect a pair of side walls.

  • Publication number: 20190017549
    Abstract: ZnO sputtering is performed while a rolling body is housed in a basket made of a metal wire and is rotated. By setting a ratio of a mesh size of the basket to a diameter of the rolling body in a range of 40 to 95%, fine and uniform ZnO coating can be formed on a surface of the rolling body. By using the rolling body with ZnO coating prepared in this manner in a bearing which is rotated at high speed in a high-load state, a friction coefficient can significantly be lowered in comparison with a case of no coating.

  • Publication number: 20190017553
    Abstract: A torque limiting assembly is disclosed comprising: an input shaft; an output shaft; a drive bush; a motion converter mechanism; a casing; and at least one engagement member for engaging the casing. In a low torque mode, rotation of the input shaft drives rotation of the drive bush, motion converter mechanism and output shaft. In a high torque mode, rotation of the motion converter mechanism relative to the output shaft urges the motion converter mechanism axially to drive rotation of the drive bush relative to the input shaft. The engagement member is coupled to both the drive bush and the input shaft such that when the drive bush is rotated relative to the input shaft, the engagement member is urged to engage the casing so as to prevent or inhibit rotation of the input shaft relative to the casing.

  • Publication number: 20190017557
    Abstract: An electronic control unit executes gradual reduction control when a friction clutch is to be maintained in a fully engaged state such that an input rotary member and an output rotary member rotate integrally. As a result, a motor current supplied to a motor is adjusted to a lower current value. Thus, an average current value of the motor current supplied to the motor when the friction clutch is to be maintained in the fully engaged state is appropriately reduced.
