Casing types
Horizontal disassembles, which have the advantage to allow carrying out medium repair to the aerodynamic component interns in fast and simple form. Due to case this game in two halves the internal flights through these unions will appear to high pressures, reason for which the rank of application for these compressors is up to 300 PSIA approximately.
Vertical disassembles, it consists of a smelting cylinder as unique central piece and two covers where to the bearings and seals are supported. The stators are a subgroup that is inserted in the cylinder casing, it has the advantage to support high pressures and allows to the maintenance men repair of the bearings and seals; the disadvantage is in the necessity of complete disarmament to be able to carry out medium repair to the aerodynamic components.

Rotor
It’s made up of the impellers and a supported central axis on the bearings in their ends, conforms the movable part of a Centrifugal Compressor.
Types of Rotors
Two types of rotors exist: Solids, are those that are made up of a central axis and the impellers fixed to this through pins, the most common technique is to warm up the impellers, taking advantage of the thermal expansion, introduce the central axis placing a pin and to wait to that the set cools off. Modular, they are made up of two shafts, a central axis and the impellers; the components are connected this yes through stretching of the central axis and nut. The shafts and impellers have holes for center the pieces and pins to transmit the torsor momentum between the components. Because the rigidity is proportional to the fourth potency of the effective diameter, in the modular rotors it increases the critical velocity, which is a rotodynamics advantage.
