Edition 22:
Solar installations are influenced by numerous local
environmental and system factors, which are such that any table of performances
and capacities must be considered indicative only. By way of example, voltage
loss along the supply cable can reduce the real voltage available at the pump,
so that the performance of one pump fitted with a long supply cable will
necessarily be lower than that of another pump using a shorter supply line,
even though the actual total head may be the same for both units. Similar factors
may affect the areas of application of the pumps. Low voltage systems, such for
example, as two panel or 24V battery driven systems, may show proportionately
greater sensitivity to local environmental and system factors than 48V four
panel systems.
Solar Spring pumps are piston pumps. Each pump has two
identical horizontal axis pistons with a diameter of 40mm. Potential pump
capacity is related to the 40mm diameter of the pistons and the length of the
stroke they make. Total displacement, and therefore the amount of water pumped,
increases with the length of the stroke. With a 2mm cam, each piston operates over a stroke of 1mm; a
2.2mm cam over 1.1mm; a 2.6mm cam
over 1.3mm; and a 3mm cam over 1.5mm.
Total heads for the various cam sizes are indicative.
They are seldom critical. A golden rule is : the smaller the photovoltaic
arrays used, and the lower the expected solar irradiation at the installation site,
the more conservative the user
should be with the chosen cam. Smaller cam units are easier to kick-start and
work better in low current and irradiation conditions. In case of doubt,
consult your supplier.
