compressor auxiliary systems

Question 1

what is the pumps purpose ?

Answer 1

supply oil under pressure to all the compressor components .

Question 2

what could be the cause of a decrease in oil pressure

Answer 2

internal component clearances could be increasing or could be a problem with oil pump

Question 2

system pressure is determined by ?

Answer 2

the bearing clearances ( restriction to flow )

Question 2

what happens if pressure is to high

Answer 2

can causes bearings to erode and oil filters to burst

Question 3

a high oil alarm could indicate a ?

Answer 3

blockage

Question 3

true or false
replacing broken parts and starting the machinery up again doe correct vibration problems

Answer 3

false it postpones its reocurrnace

Question 6

Low oil pressure can be caused by a suction inlet pipe having leaky threads.

Answer 6

true
