Pressure Governor

Question 1

What is the purpose of Fire Research pro-s?

Answer 1

Maintain a steady pump discharge pressure by controlling the engines speed or maintain a selected engine rpm.

Question 2

Pressure mode means:

Answer 2

Contestants pump discharge pressure by varying engine RPM to keep discharge pressure at the selected setting

Question 3

RPM MODE:

Answer 3

Maintains constant RPM. Psi is monitored and can vary limited to a 30psi increase.

Question 4

Governor automatically lowers RPM to reduce the psi spike at a increase of what psi?

Answer 4

30 psi

Question 5

When placing the pump in gear what will read on the pros?

Answer 5

Idle

Question 6

A minimum pump psi must be greater than __ psi for governor to take control of engine speed

Answer 6

15psi

Question 7

Increase/ decrease button selection

Answer 7

Pressure:
Press 1:
Change 1psi

Hold 2 seconds:
Change by 5psi twice and then by 10 psi

RPM:
Press 1: change by 10rpm

Hold 2 seconds:
Change by 50rpm and then by 100rpm

Question 8

Reason for high pump discharge pressure at engine idle?

Answer 8

Gate incoming water

Reduce pressure at the intake relief valve

Reduce gate discharges

Disable the pump

Question 9

When introducing water what mode must you be in?

Answer 9

RPM mode

Switching the water supply source from tank to hydrant

Draft to hydrant

Draft to relay

Question 10

Prime cycle will come on when discharge pressure drops below __ psi.

Answer 10

45psi but stays above 15psi

Question 11

During prime cycle RPM will be set to __.

Answer 11

1100 RPM

Question 12

In prime mode if pressure does not rise above 45psi in 7 seconds what will happen?

Answer 12

It will go into idle mode
