Q

Who has to test your system?

A

-Alberta Boilers Branch

2
Q

Piping System

A
  • the grid (dead end)
  • the decentralized (unit)
  • the loop system (recommended)
3
Q

Grid

A

-one compressor with feeder lines branching off a main line that starts out with a larger diameter pipe and then gets slower as it goes down the line

4
Q

Decentralized

A
  • two or more compressors with their own grids which can be interconnected or not.
  • a compressor is usually close to where it is needed through the shop so there is less pressure drop
5
Q

Loop system

A

-recommends - two or more compressors feed a single system

6
Q

How to avoid moisture problems in your system

A

-sloping the line coming from the compressor away for the compressor with the drop on top

7
Q

FRL

A

-filter, regulator and lubricator

8
Q

Code dictates your system have?

A

-gauge, drain, safety relief valve

9
Q

How does sealing happen in directional control valves in pneumatics?

A
  • packed bore
  • packed spool
  • sliding plate
10
Q

Packed bore

A

-have o-rings fixed in grooves in the bore of the valves

11
Q

Packed spool

A

-have o-rings fit into grooves machined into the spool

12
Q

Sliding plate (rotary disc)

A
