Compressor Relation: Torque, Speed & Efficiency

Click For Summary

Discussion Overview

The discussion revolves around the relationship between torque, speed, and output efficiency of compressors, particularly in the context of a project involving a motor and gearbox setup. Participants explore various aspects of compressor operation, including efficiency and losses under different conditions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant seeks a simple explanation of the relationship between torque, speed, and efficiency of compressors, indicating a lack of familiarity with the topic.
  • Another participant requests details about the project to provide more targeted assistance.
  • A participant mentions needing to find efficiency and losses at the end of a compressor driven by a motor coupled with a gearbox, emphasizing the need for equations relating these components.
  • There is a specific inquiry about the relationship between the gearbox and compressor under no load conditions.
  • A later post questions whether the speed and torque of the motor affect the compressor's CFM (Cubic Feet per Minute) and overall performance.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and familiarity with the topic, and while some seek clarification, there is no consensus on the specific relationships or equations involved. The discussion remains unresolved regarding the exact nature of the relationships between the factors mentioned.

Contextual Notes

Participants have not yet established specific equations or models to describe the relationships between torque, speed, and efficiency, and there are indications of missing assumptions regarding the operational conditions of the compressor.

Who May Find This Useful

This discussion may be useful for students or professionals in mechanical and electrical engineering who are exploring the dynamics of compressor systems and their operational efficiencies.

Hi everyone!

I am new to mechanical engineering and recently I started about compressors. I am trying to find relation between torque, speed and output efficiency of the compressor. Can anyone help me with simple explanation so that I can understand.

I will be really thankful if you could help me!

Thank you.

Which part don't you understand?
 
Thank you for the reply.
Kindly note I am an electrical engineer so I am not familiar with those topics but I am in a need of the relation between those factors for my project.

There are many types of compressors and different types efficiency that I came across; I didn't know from where to start and how those factors are related.
 
Tell us about the project .
 
The part with compressor is I need to find the efficiency and loss at the end of the compressor driven by a motor coupled with gear box and I need to find the relation between the factors that affects them. So before all, I need to get relation equations between motor, gear box and compressor.
Thank you.
 
Thank you Nidum.
I am looking for something like that but not exactly. I am looking for previous stage of relation with gear box and compressor at no load condition.

So you just want to know what the frictional and other losses are for a compressor running under no load conditions ?
 
Probably yeah.!

Thank you so much nidum. That's exactly what I was looking for.

Thanks again.

Heyyy guys,

I got another doubt! Does the speed and torque of motor have any effect on the compressors' CFM and performance?
