摘要： Size reduction of a barrel-type casing using a shear key is aimed for while ensuring a necessary area of a head cover end surface. A shoulder is formed on the axially outer side of the outer circumferential surface of a head cover. The inner surface of a casing is provided with a circumferentially extending groove. Shear key structure includes a first shear key member disposed in the shoulder and the groove, such that at least a portion of its outer circumferential surface is in contact with the inner circumferential surface of the groove, and a second shear key member disposed adjacent to the first shear key member in the groove, the second shear key member having an axially projecting shoulder, its outer circumferential surface being in contact with an inner circumferential surface of the casing. The first and second shear key members are circumferentially segmented respectively into three or more members, and each member is radially fixed to the casing but not axially fastened to each other, to allow slight displacement between the first and second shear key members by a shear force.

摘要： In a centrifugal compressor, for the purpose of preventing the positions of a diaphragm and a head flange in a radial direction from moving with respect to a casing, suppressing the generation of an unstable fluid force in a seal and the contact of the seal with a rotor to prevent the unstable vibration of the rotor and enabling an efficient and stable operation even on high-pressure conditions, there is provided a barrel-shaped centrifugal compressor including a casing, a diaphragm located in the casing to define a flow channel, and a head flange attached to the end of the casing by a shear key, wherein in the inner peripheral surface of the casing and the outer peripheral surface of abutment portions of the diaphragm and the head flange in which they are abutted on the inner peripheral surface of the casing, sliding key grooves which are vertical to the surfaces are provided at least two portions in a peripheral direction, and sliding keys are provided in the key grooves.
