    摘要: A fan housing assembly includes a mounting base formed with a through hole thereon and a bushing. The bushing has a sleeve and is coupled to the mounting base by connecting the sleeve to the through hole. The mounting base and the bushing can be separately formed with predetermined materials in view of the different quality requirements before being assembled, thus resulting in lower manufacturing cost and enhanced flexibility in the fan design.

    摘要: An apparatus for a serial ventilation device that increases airflow compared to conventional devices without increasing the size is presented. The first ventilator is mounted on the intake opening side of the serial ventilation device, with the front surface of its blades facing the air intake side. The second ventilator is mounted on the exhaust opening side of the serial ventilation device, with the front surface of its blades facing the air exhaust side. Thus a first ventilator, which ventilates from the rear side of the blades, and a second ventilator, which ventilates from the front side of the blades, operate when the ventilation side of the blades are facing the same direction and rotating in the same direction. Both ventilators are connected serially such that their rotation shafts are positioned in the same straight line, while the number of blades of the two ventilators are different.

A guide-blade cascade is capable of being pushed axially into the annular space near the outer circumference of the rotor. The guide-blade cascade includes guide blades, is guided in an annular gap between an inner part and the turbine casing and is axially displaceable via an axial slide by a sliding sleeve. The guide-blade cascade with the axial slide, the inner part and/or the sliding sleeve are produced from an austenitic cast steel material having the following components: Cnull0.2%; Si 1.5-2.5%; Mnnull2.00%; Pnull0.045%; Snull0.03%; Cr 24.0-26.0%; Ni 19-22%; and Wnull5%.

    摘要: In an axial flow hydraulic machine, a plural number of grooves 5 are formed on an inner surface of a casing, directed into a pressure gradient direction, for connecting between an inlet side of an impeller 1 and an inside of blade residing region on the casing inner surface. With movement of movable members 6 provided on the casing inner surface, the grooves appear within the blade residing region in an unstable operation region, while the grooves cause no interference with the blades of the impeller in a stable operation region.

    摘要: At a vaned diffuser or a volute casing of a centrifugal fluid machine, pressure pulsation and vibrating forces acting upon the diffuser or the volute casing are mitigated or cancelled so as to abate the noise from the centrifugal fluid machine. The fluid machine having an impeller 3 rotating about a rotating shaft 2 within a casing 1 and having a vaned diffuser 4 or volute 12 fixed to the casing 1 is constructed such that radius of the vane trailing edge of the impeller 3 and radius of the vane leading edge of the diffuser 4 or radius of the volute tongue is varied in the direction of axis of rotation and inclinations, on a meridional plane, of the vane trailing edge of the impeller 3 and the vane leading edge of the diffuser 4 or the volute tongue are set in the same orientation, thereby reduction in head and efficiency or occurrence of an axial thrust may be restrained to the extent possible to optimally abate the noise and pressure pulsation of the centrifugal fluid machine.

    摘要: A method of assembling a gas turbine engine includes coupling an inner engine casing to an outer engine casing such that an annular flow path is defined therebetween, coupling a plurality of circumferentially-spaced support struts between the inner and outer casings, and coupling a plurality of circumferentially-spaced outlet guide vanes within the flow path upstream from the support struts, such that a first circumferential spacing is defined between a first guide vane and a second guide vane, and a second circumferential spacing is defined between the second guide vane and a third guide vane. The guide vanes are arranged such that the second guide vane is between the first and third guide vanes and the second circumferential spacing is different from the first circumferential spacing.
