摘要： A method of controlling the operation of multistage centrifugal compressor equipment provided with inlet guide vanes and diffuser vanes at each stage to enable operation to be practiced at a low energy consumption level. The method includes the steps of determining whether the prevailing flow rate, for example, is in a range of flow rates near the desired flow rate or in a range of flow rates remote therefrom; and controlling a combination of the amount of operation of the guide vanes with the amount of operation of the diffuser vanes, which is set beforehand, when the prevailing flow rate is determined to be in the latter range to promptly bring the prevailing flow rate to the desired flow rate level, and effecting fine adjustments of the inlet guide vanes and diffuser vanes to control the angles thereof when the prevailing flow rate is determined to be in the former range, thereby enabling increased efficiency to be achieved in the operation of the compressor equipment.

摘要： In a high pressure centrifugal compressor, the occurrence of rotating stall noticeable in a comparatively-low specific speed wheel stage is prevented, thereby high efficient fluid performance is obtained and reliability is improved. The centrifugal compressor has a first vaneless diffuser with a constant flow channel height on the downstream side of an impeller, and a second vaneless diffuser in which the flow channel height decreases in a flow direction from an inlet to an outlet on the downstream side of the first vaneless diffuser. These diffusers are combined with an impeller using thick blades.

摘要： In a multistage centrifugal compressor, a plurality of impellers is attached to the same rotary shaft. Vaned Diffusers and vaneless diffusers are used, as diffusers, for respective compressor stages configuring the compressor. The vaned diffusers are continuously used from the first compressor stage to the middle compressor stage, and the vaneless diffusers are used for the last compressor stage and the previous stage. While high efficiency is maintained at the compressor stages having the vaned diffusers, an operating flow range is secured at the compressor stages having the vaneless diffusers.

摘要： A low pressure-side first-stage compressor impeller and a high pressure-side second-stage compressor impeller are mounted respectively on opposite ends of a rotation shaft. A rotor of an electric motor for driving the two impellers is formed at a central portion of the rotation shaft. A stator of the motor is held by a motor casing. The motor casing, a first-stage compressor casing, which cooperates with the first-stage compressor impeller to form a first-stage compressor, and a second-stage compressor casing, which cooperates with the second-stage compressor impeller to form a second-stage compressor, are cast into an integral construction. This integral casing is further formed integrally with an intermediate cooler, disposed downstream of the first-stage compressor, and a discharge cooler disposed downstream of the second-stage compressor. The intermediate cooler and the discharge cooler are disposed below the motor casing in generally parallel relation to the rotation shaft, and the main portions of the two-stage centrifugal compressor are combined into a compact, generally rectangular parallelepiped configuration.

摘要： A plurality of vaned diffusers is disposed on a concentric plate at intervals in a circumferential direction thereof, and each of the diffusers is a curvilinear element three-dimensional diffuser having blades which are extended from a hub side of a impeller to a shroud side thereof. The blades are formed in a form in which a blade serving as a reference is stacked in a direction of the height of the blade, which is a direction of a gap between the hub and the shroud. A dihedral distribution in which moving in a direction perpendicular to a chord direction linking a leading edge of the blade as the reference with a tailing edge thereof, is set as a positive movement is non-uniform from an end portion on the hub side to an intermediate portion of the height of the blade.

摘要： A centrifugal compressor is equipped with an impeller having a blade angle distribution that makes it possible to achieve a relatively wide operating range. The blade angle of a shroud side facing a circular plate of a blade is termed a first angle and a blade angle of a hub side disposed at the circular plate is a second. The shroud side is formed in a curved shape having an angle distribution from a front area in a shaft direction toward a centrifugal direction in which the first angle is the local maximum point before a substantially middle portion and the local minimum point after the substantially middle point. The hub side is formed in a curved shape having an angle distribution from the front area in the shaft direction toward the centrifugal direction in which the second angle is the maximum local point before the substantially middle portion.

摘要： A multistage centrifugal compressor has a shaft rotatable on an axis and a plurality of centrifugal impellers fixed on the shaft and having outlets at outer peripheries thereof. Conduits connect the impellers to from a path for fluid undergoing multi-stage compression by the impellers from a suction side to a delivery side. The conduits including a plurality of diffusers arranged radially outwardly from the impellers, each impeller and associated diffuser constituting a stage. At least two of the diffusers are vaned diffusers provided with vanes having leading edges at their inlet ends. To provide high efficiency combined with low risk of rotating stalls, among the vaned diffusers, the ratio of diffuser vane leading edge radius to impeller outlet radius increases along the fluid path from the delivery of the compressor to the suction side.

摘要： A centrifugal compressor includes an impeller and a diffuser arranged around the outer periphery of the impeller and including a pair of annular, spaced diffuser plates defining a diffuser channel therebetween. A plurality of guide vanes are provided on at least one of the pair of diffuser plates to guide a low flow angle portion of a fluid flow introduced into the diffuser channel from the outlet of the impeller. The guide vanes each extend from the inlet of the diffuser channel to a position which does not exceed about one half the distance between the inlet and the outlet of the diffuser channel and have a height which is less than one half the spacing between the pair of diffuser plates.
