output of the pumping equipages and the optimum diameter of the piping. The
replacement of the existent equipment, that is obsolete from physical and
technological point of view, must be done with new equipments with
performances that will meet the requirements of an optimum operation from
both energetic and economic perspectives, [2].
2. Methodology
This analysis is more likely to be of academic rather than practical interest,
however, since the main requirements with regulated flow are:
a) To achieve the required variation in delivery to meet demand variations.
b) To realise good pumping efficiency at all demand levels, [3].
The connections analyze between the functional parameters of pumping
station and the quality parameters of drinkable water are:
a) The connections estimation between the pump’s load, debit and the water’s
turbulence.
b) The values analyze of chlorine and ammonium concentration depending on
debit.
c) The water conductivity analyzes depending on debit.
The best power and economical performances will correspond to the
pumping solution which ensures the covering of the request area (Q, H) with the
best output. The pumping efficiency is established by studying technical
implications of modernization measures of the power station. It is imperative to
use the automatic systems for the water treatment. Energy efficiency and
economic efficiency for the pumping supply system are tightly connected to the
proper choice of pumping device and appropriate operation of the hydraulic
system, [4].
The evaluation of connections between the functional parameters of
hydraulic systems and the quality indicators of water, depending on time is
obtained with the help of an original automatic calculation program, elaborated
by authors. Allowing for the actual situation of the adduction and the
effectuation’s necessity of the repair workings capital or the pipe’s replacement
in some sectors, respective of the pumping aggregates, for to assure a powereconomical
evolution favorable of the system, one are determined: the optimum
nominal diameter of the pipes and the maximum theoretical outturn of the
pumps what must be used and the change’s convenience of the existing
equipment, [3].
Depending for the installation’s total outturn and for the water volume W
circulated in the period of reference, the consumption of power for the water’s
pumping Eso is independent at stop’s duration „at top”:
