| Abstract | The performance of a coil tube pump modified in AIT was
evaluated both by variable speed motor and by manually. Maximum
lift was found to b e 275 cm by using 1 2 turns in the coil.
Suitable rpm for manual operation was found to be in between 35
to 25 rpm and within this speed range a labor can operate this
pump continuous l y for 45 to 60 minutes. For lift 100-275 cm power
requirement for 30 rpm was 16-72 watt and maximum discharge and
efficiency were found to be 58 litre/min . and 60 % respectively .
For this speed , the optimum angle of operation was found to be 24
degree (7 5 % diameter coil submergence ).
Keeping average input power 30 watt (arms/ shoulder) a nd 75
watt (pedaling ) fixed cu t off points at different lifts were
calculated. Best cu t - off point for 30 watt and 75 watt occurred at
25 rpm a nd 48 rpm at lift 24 0 cm and 250 cm at which efficiency
was 61% and 45 % respectively.
The overall performance of the coil tube pump is good. So
there is a need to popularize this pump suitable for supplying
irrigation water to vegetables, rice and wheat fields in the non-industrialized countries. |
