ABSTRACT Experiment on performance evaluation of water lifting pump .The study was undertaken to determine the performance of submersible pump set of 15HP and mono-block centrifugal pump set of 5 HP to develop characteristic curves of and its operating conditions. The results revealed that Submersible pump the maximum all over pump set efficiency was found 54.98 % at working head 40.43 m, discharge equal to 24.10 lps, Water Horse Power 12.99 and input Horse Power 23.63, it was operating point of pump. More than 50 % efficiency can be achieved with discharge capacity variation between 24.10 to 17.89 lps at total head variation between 40.43 m to 52.16 m. While in Mono-block centrifugal pump testing was done for suction lifts 0.5 m, 0.7 m, 1.6 m and 2.5m, the maximum efficiency was found 75.10 % at 0.7 m suction lift and at 29.34 m head under same static lift minimum efficiency was found 47.94 % at 16.58 m head. As more than 20 m head was not advisable, also under 0.7 m suction lift more than 17 m head may create cavitation. So, operating head may be adopted 17 m against this head maximum efficiency is 48 %, discharge 11.9 lps and 5.5 HP. Also compromise with slight possible cavitation at 20 m head 60 % efficiency can be achieved it was optimum operating point of mono block pump |
