Reciprocating & Screw Compressors Operation and Maintenance.
Course Schedule
Reciprocating & Screw Compressors Operation and Maintenance.
Compressors are essential components in almost all industries in
that they are required to meet system demands and operate reliably.
Failure to meet these requirements can have significant production (and hence
cost) impacts.
By attending this course you will gain an understanding of the
characteristics of various types of Reciprocating compressors and their
components. The course will provide engineers and technicians with
information for the optimal selection, operation and maintenance of positive
displacement compressor, reciprocating compressors
In this course we will define the functions of each major
component of a reciprocating compressor. That is, what the purpose of each
component is or "What It Does". By understanding what each component
is supposed to do, you will be in a better position to know if it is performing
its duty correctly. We will present each major component starting with the
crankcase, state its function, operating limits and what to look for. After
presenting each component's general information, we will present specific
information concerning site compressors
Also A rotary screw compressor is a type of gas compressor which
uses a rotary type positive displacement mechanism. They are commonly used to
replace piston compressors where large volumes of high pressure air are needed,
either for large industrial applications or to operate high-power air tools
such as jackhammers.
