CFM (A.S.M.E.) @ 15" Hg_________________________ Type ____________________________________

Remarks ___________________________________________________________________________________

CFM at operating vacuum level ____________________________________ @ _____________________" Hg

Pump #4

Make __________________________ Model __________________________ HP ______________________

CFM (A.S.M.E.) @ 15" Hg __________________________ Type ____________________________________

Remarks ___________________________________________________________________________________

CFM at operating vacuum level ___________________________________ @ _____________________" Hg

Total Pump CFM's ___________________________, (Pumps used for milking, not spares)

2.System vacuum level ____________________ " Hg. System vacuum gauge level _______________________" Hg.

3. System Check

All regulators closed off or removed. Flow meter in receiver jar if possible, or in controller opening.

Pulsators off, units in milk mode. Claws shut off or hoses taped shut: results should be within 10% of pump capacity.

System check _________________________ CFM, Pump CFM's ______________________ -System check

CFM's = ___________________________ CFM leaks.

4. Vacuum Controller Response

Regulators installed, system as in system check, flow meter in receiver jar. Air admitted into flow meter in 10 CFM bursts up to 75% of system capacity. Vacuum gauge on flow meter should not deviate more than + or -.5" Hg.

Controller Response __________________________________ good or poor. Controllers clean? _________________

5. Vacuum Controller Leakage (optional)

Set up as in #3 above. Take CFM at .5" Hg. below system vacuum level (a) ______________________ CFM A.S.M.E. Set system as in #3 above and record CFM's at 0.5" Hg below system vacuum level (b) ____________________ CFM.

Leakage = a - b = __________________________ CFM.

Some diaphragm controllers use 10 CFM to clean themselves.

6. Pulsators

  1. How many pulsators? _____________ Make _____________ Type: Vacuum or electric ___________________

  2. Air vents or caps clean and area free of cobwebs? _________________________________________________

  3. Pulsation rate and ratio: (see Table 1 )

7. Cluster

  2. All claw or liner vents open? ___________________________ Both? ___________________________

  3. Vacuum shut offs on claw or milk hoses? ___________________________ Used? ___________________________

  4. Liners changed at 1200 cow intervals? ___________________________

  5. Liners free of tears or holes and in good condition? ___________________________

8. ATO's

  1. Are sensor jars clean? ___________________________

  2. Floats installed correctly? ___________________________

  3. Sensors level and secure? ___________________________

  4. Sensors installed as low as possible? ___________________________

  5. Milk hoses in sensors or milk hoses at crimp off point collapsed? ___________________________

9. Milk Line

  2. Is this pipe cleanable? ___________________________

  3. Ever been cleaned? ___________________________ How often? ___________________________

11. Pulsator Lines

  1. Diameter ___________________________"

  2. Looped ___________________________

  3. Cleanable ___________________________

  4. Ever been cleaned? ___________________________ How often? ___________________________
