Syllabus

The topics that follow are intended to be a study guide, and in no way implies that additional knowledge obtained from experience is not needed to successfully challenge the Compressor Operator Examination.

1. FUNDAMENTALS:

a. Fully explain the theory of air/gas compression.

b. Describe how altitude and moisture affects the compression of air.

c. Describe the principles of operation of positive displacement and dynamic compressors.

d. Define air compression terminology such as absolute and gauge pressures, compressor

e. Displacement and compressor capacity, free air, volumetric efficiency, single and double acting, single and multistage.

f. Given relative data, perform basic calculations to solve for compressor displacement and compressor volumetric efficiency.

2. RECIPROCATING COMPRESSORS:

a. State and describe the different types of single and multi-stage reciprocating compressors, state the function of the various compressor parts, including valves.

b. Describe the methods employed to cool air or gas during compression.

c. List and describe the different types of prime movers used for compressors.

3. ROTARY COMPRESSORS:

Fully describe the principles of operation, their application, volume and pressure capabilities, methods of regulation, advantages and disadvantages of the following types of (positive displacement) rotary compressors:

a. sliding vane

b. the lobe type

c. roots type

d. screw

e. liquid-sealed

4. CENTRIFUGAL AND AXIAL COMPRESSORS:

a. Describe the design and operation of the volute and diffuser type centrifugal compressors.

b. Describe the design and operation of the single-stage double-flow and the four-stage centrifugal compressors.

c. Fully describe the design and operation of an axial flow compressor.

d. State the causes and remedies of compressor surging.
