MINI HYDRO POWER AXIAL FLOW PUMPS

HYDRO TURBINE (MICRO / POWER GENERATION)

The Solomon family has been growing 100 ha of maize on their 1125 ha farm for many years and in 1991 had an outlay of R110000 (about $35000 in 1991) when they installed a 40kw water turbine system on the Umgeni River for irrigation purposes.  The system was estimated to pay for itself within a period of five years and would provide a lifetime of of power with minimal maintenance costs. (Singh 2001).

The water driving the turbine flows along a canal which is about 0,80km long.  At the end of canal 400 litres/s is fed into a MONAX Type 24 turbine through a 750mm diameter pipe with a fall of 12m.  The actual power that can be generated is about 50kw but allowing for losses and efficiency about 40kw is obtained.
The MONAX turbine runs at 750RPM and drives a Southern Cross RHF100 centrifugal pump through the Vee belt drive.

The capacity of the driven pump is 180 kilo litres/hour (53m) (180m/hr) at a pressure of 520KPA.  The water is pumped into a dragline sprinkler system that was upgraded which are used to irrigate 50 ha of pastures for dairy cows.

This power is available day and night 24 hours per day, year in an year out at no cost above normal maintenance.
In terms of the cost analysis the maintenance involves changing a flat belt twice a year plus bearings and brushes occasionally.  Further calculations show that the initial cost in 1991 was two thirds of that the grid of supply, which was recovered over 5 years (D Singh 2001).

Power = QxHxSG/367e
Delivery: 520KPA = 53m water
180 Kilo Litres = 180m/hr flow
System Efficiency - 65%
40kw @65% = 50l/s delivered @ 58m pressure
