9.3.1. Manually applied lubrication
Sealed bearings do need to be re-greased at times as hydro turbines run 24/7 and see very
high cycle rates. The PowerSpout is provided with a re-greasing nipple so this can be easily
done with the turbine in operation.
You should lubricate your PowerSpout bearings at the time you first use it and then:
Every 12 months for generation up to 300 W.
Every 6 months for generation up to 600 W.
Every 3 months for generation up to 1600 W.
A good quality grease must be used. We recommend
SKF LESA 2 grease for all PowerSpout applications or
a close equivalent.
With the turbine running connect your grease gun onto
the grease nipple provided. Pump into the bearing
block about 20 mL of grease when first
commissioning. This is normally about 20-50 pumps of
a domestic type grease gun. Subsequent re-greasing
should be about 5 mL of grease (about 5-10 pumps).
If you remove the magnetic rotor you should see a
band of new grease on the bearing dust seal. If not you need to grease a little more.
If you turn your turbine off during the dry season or for any period greater than 2 weeks you
should lubricate as above prior to turning off.
Remember, your PowerSpout 3-year warranty is conditional on bearing replacement every
12 months and the above lubrication regime that you should document in your log book.
9.3.2. Auto-grease cans
If you purchase 3 auto-grease cans at the same
time as your turbine, all you have to do is replace
and activate the grease can every year; the
bearings can then be replaced every 3 years. An
annual inspection is still required.
Before activating the auto-grease can
you have to manually charge the
bearing block as described earlier or
an early bearing failure may occur.
