Wear and tear on the motor brushes is such that after a number of years
(indicatively 5-7 years) they will need to be replaced. It may also be good
practice to replace the brush springs on such occasion. The need for a brush
change is indicated by simple stoppage of the pump caused by the spring
mechanisms which reach an end stop blocking pressure on the brushes so that
current no longer passes to the motor. Unnecessary repeated opening of a pump
to check brush wear can be harmful in that it introduces more air and therefore
oxygen into the motor chamber thereby aggravating the possibility of corrosion
of certain parts. Where pumps have been installed in the framework of a rural
water supply project, they should be pulled at 5-6 year intervals and the brushes
changed irrespective of their condition.
Lift the
arms of the spring clips on the two black motor brush holders (344) on the
bottom end of the motor and remove and examine the brushes (344).
Note : The Solar Spring brushes have an expected life span of between 3 and 5
years' continuous use, and are protected at their external end in such manner
as to avoid sparking in case of total wear.
The actual length of the brushes when new is approx 15mm.
The usable length of the brushes is : 12mm
Each millimetre of usable length represents indicatively a life of 400 hours
actual use, usually more.
If the remaining brush length is 6mm or less, the brushes should be replaced.
If the brushes are not replaced, it is wise to register remaining brush length
for future use.
Check
fast-on terminals and spades (359), earth nut (360) and earth spade (360). They
need to be removed only when the motor itself (343) or the motor shroud (358)
or the electric cable (363) has/have to be replaced.
