6 FAQs about [Screw type air compressor case analysis]

What is the DC level of a screw compressor?

Below, in figure 10, the envelope spectrum has a DC level of 1.45 g’, indicating bearing wear. In the case of this screw compressor, the thrust bearings are located on the inboard side of the male and female lobes, which is why we found the highest vibration readings on these inboard bearings.

What is a twin screw air compressor?

The twin screw air compressor is a positive displacement compressor and has been widely used in gas industries. One of the major advantages of the twin screw compressor is its flexibility under various operation conditions. It utilizes the continual variations of the space formed between rotor grooves and case of the compressor.

What are the problems with screw compressors?

Most screw compressors have sleeve bearings, but they often also have thrust bearings that are roller bearings. If these thrust bearings wear and fail, they will cause a catastrophic failure of the machine. Vibrational analysis is a great way to detect these problems.

Do screw compressors have pulsation and vibration problems?

The vibration on the shell wall was successfully reduced to below the 1 IPS vibration guideline. The case study demonstrates that, like reciprocating compressors, screw compressors can have pulsation and vibration problems since they are positive-displacement machines.

How do you diagnose a screw compressor problem?

The way to analyze any machine problem is by diagnosing the specific frequencies the data reveals. Most screw compressors have sleeve bearings, but they often also have thrust bearings that are roller bearings. If these thrust bearings wear and fail, they will cause a catastrophic failure of the machine.

Why is screw compressor used in refrigeration & air conditioning industry?

ABSTRACT The screw compressor is widely used in refrigeration and air conditioning industry due to it high efficiency. The screw compressor are said to have an efficiency of about 75% to 80%. The one percent of efficiency of the screw compressor is lost due to some of the losses which restrict it from being 100% efficient.
