Pump Measurement Procedure

This section will detail the procedure that will be used for gathering ram measurements.

The data that will be gathered in the Spring 2012 assessment

  1. Name/pump number ______
  2. Length of drive pipe ______ft.
  3. Drive pipe OD _____ in. ID ______in.(dam to pump)
  4. Delivery pipe/hose OD ______in. ID ______in Material ______(pump to sprinkler)
  5. GPS reading at pump. If pumps are in a cluster, one reading would be sufficient.
  6. Two average flow (3 timed bucket readings) vs pressure readings taken at pump with test apparatus.
  7. Two average waste flow rate measurements. (To be used in calculating efficiency)
  8. Pressure at the pump when there is no longer any flow (shutoff head) _____ psi
  9. Normal operating pressure at pump (taken with needle adapter and gauge through hose) _____ psi
  10. Distance waste valve moves. Is it adjustable?
  11. Frequency of pump in cycles/minute.
  12. Take video of three(?) ram pumps. (To be given to???)
  13. Two average flow (3 timed bucket readings) vs pressure readings taken at the highest point from the delivery pipe/hose.
  14. Pressure at highest point from the delivery hose (taken with needle adapter and gauge through hose) _____ psi
  15. GPS reading where flow vs pressure data from delivery pipe/hose was taken.
  16. Estimate size of fields in square yards owned by family.
  17. Estimated area in square yards currently irrigated.
  18. Crops currently being irrigated.
  19. Crops family would like to grow if irrigation system is improved.
  20. GPS reading at crop field point that is the highest and furthest from pump.

Group the following families that would like to receive a ram pump and irrigation system by dam number.

  1. Name
  2. Estimate size of fields in square yards owned by family.
  3. Crops the family would like to grow if they could get an irrigation system.
  4. GPS reading of crop field point that is the highest and furthest from nearest dam.
  5. Crops currently grown.

Pump Measurement Instruction

  1. Pumps will be numbered according to where the drive pipe is located on the dam. Facing upstream the pumps are numbered from left to right. This includes all pumps connected to the dam and not just those being measured
  2. Take a picture of the dam from downstream side facing upstream
  3. Include ram pump owner's name with each ram pump
  4. Length of drive pipe. Use measuring tape
  5. Drive Pipe(dam to pump) outer diameter and inner diameter. Use measuring tape or ask Don Gregorio.
  6. Delivery pipe(pump to sprinkler. Use measuring tape or ask Don Gregoro.
  7. GPS measurement. Single reading if pumps are clustered. See GPS units instruction manual for specifics. Any sort of “save waypoint” will do.
  8. Identify pumps that has a feed pipe which allows for easy attachment appartus to ram pump feed pipe.
  9. Take a 5 gallon bucket using a stopwatch measure time it takes to fill the bucket. Repeat twice.
  10. Pressure at the pump feed pipe.
  11. Pressure at pump
  12. Waste valve stroke length. Use measuring tape.
  13. Count stroke over 30 seconds or a minute and adjust accordingly for cycles/min
  14. Take video of a few (less than 3) ram pumps in operation
  15. At outlet of feed pipe measure flow rate using 5 gallon bucket and stop watch. Adjust pressure using provide valve
  16. Measure pressure using needle adapter
  17. Take a GPS waypoint at location of feed pipe outlet
