centrifugal compressor diaphragm

Accordingly, power for allowing an amount of a total flow rate of 550 of the gas G to flow through the impellers 3 of the stages is required. portion of working fluid from a first location 14 to a second location 15 near the impeller 3. 11. Further, the impeller 3 may be a closed impeller at which the shroud 13 is installed as in the embodiment, or may be an open impeller at which the shroud 13 is not installed unlike the embodiment. The inlet is formed at an upstream end in the axis O direction of the impeller flow channel FC0. Compare. Hereinafter, the impellers 3 are a first stage impeller 3a, a second stage impeller 3b, a third stage impeller 3c, a fourth stage impeller 3d and a fifth stage impeller 3e that are disposed from the upstream side to the downstream side through which the gas G flows (from one side to the other side in the axis O direction). In addition, the diaphragm may further include a first vane disposed in the inlet-side flow channel and configured to guide the fluid in a desired direction; and a second vane disposed in the outlet-side flow channel and configured to guide the fluid in a desired direction, wherein the communication section is disposed between a position closer to an upstream side than the first vane and a position closer to a downstream side than the second vane. The previously mentioned gap 10 is defined between the second portion 2c of the rear surface 2 and the shroud 3b of the impeller 3. The desired direction is, for example, a direction inclined forward in a rotational direction of the impeller 3 with respect to the radial direction to apply prerotation to the gas G suctioned from the outside. BR, Ref document number: A compressor is a machine which accelerates the particles of a compressible fluid, e.g., a gas, through the use of mechanical energy to increase the pressure of that compressible fluid. During operation, the working fluid enters in the vanes 3b between the blades 16 and exits energized from the outlet 3e at the tip of the impeller 3. The intermediate flow channel FC3 has a diffuser flow channel FC4 (an outlet-side flow channel) extending outward in the radial direction from the outlet of the impeller flow channel FC0 in the first stage impeller 3a, and a return flow channel FC5 connected to the diffuser flow channel FC4 and extending toward the inlet of the impeller flow channel FC0 of the second stage impeller 3b. A region surrounded by the blades 12 neighboring in the circumferential direction, the hub 11 and the shroud 13 is an impeller flow channel FC0 through which the gas G flows. The duct 5 comprises a first portion 5a which develops from the inlet 6, in particular transversally with respect to a radial direction "A". 1. A diaphragm (4) rotatably covers an impeller (3) around an axis (O). 8. Contact Supplier. The casing flow channel FC through which the gas G flows is formed in the casing 4. A seal placed on the impeller eye, namely the lower diameter of the external side of the shroud, has the purpose to limit such recirculation. However, in the system of provisionally recirculating the gas G through all of the stages of the system from the downstream side of the fifth stage impeller 3e to the upstream side of the first stage impeller 3a, a flow rate of the gas G flowing through the impellers 3 of the stages is 110. In vertical split–barrel type compressor the diaphragm halves are kept together by tie-rods thus making up two separate … Impellers can be shrouded or unshrouded. Accordingly, the occurrence of the surging can be more effectively suppressed. US $27.00 / Piece. A first embodiment of the invention therefore relates to a diaphragm for a centrifugal compressor. The intermediate flow channels FC3 are formed in the casing 4 at a position between the first stage impeller 3a and the second stage impeller 3b, a position between the second stage impeller 3b and the third stage impeller 3c, a position between the third stage impeller 3c and the fourth stage impeller 3d, and a position between the fourth stage impeller 3d and the fifth stage impeller 3e. KR, Ref document number: The rear surface 2 also has a second portion 2b, which faces the impeller 3, in particular the shroud 3c. For example, labyrinth seals or honeycomb seals can be used as internal seals at, for example, a balance piston and an impeller eye (or each impeller eye in a multi-stage centrifugal compressor). The further seal 11 preferably has a diameter comprised between the one of the seal 8 and the maximum diameter of the shroud 3c. Application filed by Nuovo Pignone Tecnologie S.r.l.
