摘要： A vibration diagnosis method for a rotary machine is disclosed. The presence or absence of a self-excited vibration is determined by checking if a rotating speed is in a rotating speed range which allows the occurrence of the self-excited vibration, if an amplitude of a frequency component corresponding to a first order critical speed is larger than a predetermined level, and if phases at characteristic points of vibration signals change among cycles.

摘要： A balancing method for use in a multiple-span rotor shaft system for a prime mover, such as a large-capacity, large-sized steam turbine and generator. A balancing influence coefficient representing the relationship between a unit weight and the resultant vibration, when the aforesaid unit weight is attached to a given balance-correcting plane of a multiple span rotor, is first determined, and then a balance-correcting plane, to which is to be attached a balancing weight, is selected, then a balancing weight is determined so as to minimize the value of the residual vibration amplitude, by using the method of least squares, which values are dependent on the value of the vibration amplitude, influence coefficients and balancing weights. Thus, a weight corresponding to the aforesaid balancing weight is attached to the aforesaid balance-correcting plane to reduce vibrations in a shaft.

摘要： Steam introduced into a turbine casing from a steam inlet is longitudinally divided and each divided steam portion flows in respective first stages which are disposed on the shaft adjacent to each other. The shaft and a plurality of disks which are manufactured independently are made integral by a thermal shrink. In order to reduce the thermal distortion effects on the shaft caused by keys interconnecting the disks and shaft, first key grooves formed on an outer surface of the shaft and an inner surface of the disks of one first stage and a first key closely disposed in the first key grooves are arranged in symmetry with respect to the center of the shaft, to second key grooves formed on an inner surface of the disk of the other first stage with a second key closely disposed in the second grooves. Other preferred embodiments include dummy grooves and keys to balance the thermal distortion effects of the keys interconnecting the disks and shaft.

摘要： A vane pump comprising a cylindrical pump chamber, vanes adapted to rotate within the pump chamber, and a drive rotor arranged eccentrically with respect to the center of rotation of the vanes, such vane pump being formed with through holes in portions of opposite end walls of the drive rotor which are in spaced juxtaposed relationship with side end faces of each vane, such through holes being connected to a line for supplying therethrough a portion of the fluid discharged by the vane pump. During operation of the vane pump, the portion of the fluid discharged by the pump and supplied through the line is ejected through the through openings against the side end faces of the vanes so as to avoid collision between the end walls of the drive rotor and the side end faces of the vanes whereby the service life of the vane pump can be increased.
