Dynamic Characterization of Fully Partitioned Damper Seals NEW PROPOSAL
نویسندگان
چکیده
Balance piston seals are subjected to large pressure differential and can generate large forces directly impacting the stability of centrifugal compressors. The most common designs are textured seals such as honeycomb, hole-pattern seals, and pocketed seals including pocket damper seals (PDS) and fully partition damper seals (FPDS), shown in Fig. 1. The dynamic performance of textured seals have been extensively characterized and compared to each other under similar operating conditions [1,2]. PDS and FPDS have also been tested in multiple test facilities and conditions, but the amount of data is limited and there is still missing a complete data set that can be used for direct comparison of stiffness and effective damping to textured seals.

Gas Damper Seal Test Results, Theoretical Correlation, and Applications in Desi
The rotordynamic and leaking characteristics of two types of gas damper seals, honeycomb seal and pocket damper seal, were experimentally evaluated on a rotating test rig. The effect of supply pressure, preswirl, and seal eccentricity on seal dynamic performance was investigated in the tests. The pressurized working gas flowed through the seal and exhausted to atmospheric conditions. The maximu...
متن کاملFlow Seals Parameters Analysis For Rotors
The interaction of work fluid mechanics with that of the rotary system itself, basically composed of axes, bearings and rotors, is performed by inserting equivalent dynamic coefficients in the mathematical model of the rotor, the latter being obtained by the finite element method. In this paper, the dynamic coefficients of inertia, stiffness and damping of the flat seals analyzed here are evalu...

This paper is concerned with a new fully adaptive control scheme for vibration isolation using a semi-active MR damper installed between ground and first floor, which is composed of two adaptive controllers. One is an adaptive inverse controller which can give necessary input voltage to MR damper so as to generate specified reference damping force to be acted on a controlled structure. The inpu...
متن کاملA Fully Integrated Method for Dynamic Rock Type Characterization Development in One of Iranian Off-Shore Oil Reservoir
Rock selection in modeling and simulation studies is usually based on two techniques; routinely defined rock types and those defined by special core analysis (SCAL). The challenge in utilizing these two techniques is that they are frequently assumed to be the same, but in practice, static rock-types (routinely defined) are not always representative of dynamic rock-types (SCAL defined) in the re...
