outcome 6 Flashcards
work absorbing devices which are used for increasing pressure of fluid at the expense of work done on fluid
Compressors
The compressors used for compressing air are called
air compressors
compressors from low pressure in inlet and high in outlet ( T or F )
T
Based on principle of operation
Positive displacement compressors
Non-positive displacement compressors
Reciprocating compressors may also be single acting compressor only ( T or F )
F
Based on number of stages:
single : up to 5 bar
two : 5 to 35 bar
three: 35 to 85 bar
fore : above 85 bar
Based on capacity of compressors
low : up to 0.15 m3/sec
midum : 0.15 to 5 m3/sec
high : above 5 m3/ sec
Based on highest pressure developed
low : up to 1 bar
miduem : 1 to 8 bar
high : 8 to 10 bar
extra high : above 10 bar
draw and expline what is the reciprocating compressores
when postion move dawn at section stoke the voluum increase with increase with cylender and pressure become lower
when pistan move in upword at comoresstion section the voluum dicrease wuth cylender and pressure increase
ad
easy to repair
cost effect for low voluum
limited flow capacity
cost
noisy opration
