3D animation of screw compressor working principle

Summary

Man Diesel and Turbo designs and manufactures tailor-made process gas screw compressors using a modular system of proven components to ensure high reliability. These compressors handle volume flows from 200 to 100,000 cubic meters per hour, operating on the principle of positive displacement with intermeshing spiral rotors. Gas enters chambers formed by the rotors, is transported to the discharge side, and compressed continuously. This combination of positive displacement and rotating machine benefits makes screw compressors versatile for numerous applications and process gases. Since 1952, Man Diesel and Turbo has produced both oil-free and oil-injected compressors at its Overhousen facility, serving global process industries.

Q & A

What type of compressors does Man Diesel and Turbo manufacture?

Man Diesel and Turbo manufactures tailor-made processed gas screw compressors for customers, using a modular system of tried and tested components.

What is the range of volume flows that a compressor stage can handle?

Depending on its size, a compressor stage can handle volume flows ranging from about 200 to 100,000 cubic meters per hour.

What basic principle do all screw compressors operate according to?

All screw compressors operate according to the principle of a positive displacement machine, with the key element being a pair of spiral rotors.

How do the rotors function during compression?

During operation, the rotors turn and their spiral teeth mesh together, forming chambers that move from the suction side to the compression side, filling with gas and compressing it.

How is gas introduced into the compressor chambers?

The chambers are connected to the suction nozzle via ports. As the chambers enlarge, they are filled with gas flowing in through the nozzle.

What happens to the gas once it is transported to the discharge side?

Once the chamber reaches the discharge side, it shrinks, compressing the retained gas, which then flows out through a discharge nozzle.

Why is the compression process in screw compressors considered continuous?

Because all chambers between the two rotors are being filled and emptied simultaneously, making the compression process more or less ongoing.

What advantages does a screw compressor design combine?

The design combines the advantages of a positive displacement machine with those of a rotating machine, making it suitable for a wide range of applications and process gases.

Since when has Man Diesel and Turbo been developing and constructing processed gas screw compressors?

Man Diesel and Turbo has been developing and constructing processed gas screw compressors at its Overhousen location since 1952.

What types of compressors does the company offer for process applications?

The company offers both oil-free and oil-injection compressors for process applications, making it one of the few companies worldwide to do so.
