The relative position of the thrust collar and the thrust bearing assembly determines the axial position of the rotor within the impeller opening (blade height, discharge side) and the opening of the diffuser, as well as the position of the suction diaphragm. -----------------------------------------------------------------------------------------------------------------------------------------

The relative position of the thrust collar and the thrust bearing assembly determines the overall position of the rotor within the impeller opening, the blade height, the discharge side, as well as the opening of the diffuser and the position of the suction diaphragm. The mention of blades in the diffuser suggests that it is a centrifugal compressor. Echommm, how should I handle the two openings? The first one is the opening angle, and the second one is the actual hole?

Based on the information you provided, it seems impossible to determine the specific type of compressor. Given that a diaphragm is involved, it could possibly be a \"centrifugal diaphragm compressor\"; this is just for reference.
(Exit side at the top of the blade) I’m not quite sure about this height; it would be better to have a professional in pump technology explain it.

Does “blades height discharge side” mean that the height of the blades is on the outlet side? It’s just a guess – I really don’t have any experience in this area. Please be understanding
Impeller opening (blades height discharge side): This refers to the opening on the discharge side at the top of the blades; it will be clearer if there is a diagram.
The end user cut out all the relevant images in order to save on translation costs—it’s absolutely outrageous. Moreover, this material was provided by an Italian company, and some of the terms used are not very standardized; therefore, it is difficult to understand without the accompanying diagrams. Temporarily designated as: blades height discharge side – blade height on the exit side (I don’t even understand what this means!) ), those with different opinions please go ahead. :handshake :handshake :handshake
height n. height, elevation, high ground (usually used in plural form), apex; blades height discharge side apex of the blades on the exit side
discharge side: the side where unloading takes place; the vertex of the blade on the unloading side? ___
Centrifugal compressor: It is mainly composed of two major parts, the rotor and the stator. Working principle: When gas enters the impeller of a centrifugal compressor, it rotates at high speed along with the impeller under the action of its blades. Driven by the centrifugal force generated by this rotation, the gas flows toward the impeller’s outlet, where it is expanded by the impeller, resulting in an increase in both its pressure energy and kinetic energy. After entering the diffuser, the kinetic energy is further converted into pressure energy. The gas then passes through bends and return streams to reach the next stage of impellers for further compression, thereby achieving the pressure level required by the process.
The relative position of the thrust collar and the thrust bearing assembly determines the axial position of the rotor within the impeller opening (at the blade tips on the discharge side) and within the diffuser opening, as well as the position of the suction diaphragm. The relative position of the thrust ring and thrust bearings determines the axial location of the rotor at the inlet of the impeller (at the tips of the blades at the discharge side), as well as the position of the outlet of the diffuser and the suction diaphragm.
