2.9. Optional extras you may wish to order
Check the pricelist for additional items that you may wish to have shipped with your turbine
at no extra shipping cost in many cases. The list includes some useful tools, for example,
the DC current clamp meter, which is indispensable for trouble-shooting battery systems of
all kinds.
2.9.1. Bearings
You will need to check the bearings every year and replace if required. (Note that our
warranty terms require annual replacement if automatic grease cans are not installed).
Bearings are inexpensive and easy to replace, see section 9.4. We recommend you hold a
spare set of bearings on the shelf. Some of our Pelton turbines have been running on
original bearings at customer sites for over three years, though we do not recommend that
you do this unless an automatic grease can is fitted.
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.
Many customers order a spare shaft and bearing block unit
for quick replacement and minimum downtime. Then the bearings can be changed at your
leisure.
2.9.2. Manifold fittings
The PLT and TRG models of turbine require pipework and fittings to connect them to your
main pipeline or "penstock". You can buy these items from PowerSpout or locally. It's worth
checking the pricelist to see what can be delivered directly and save effort. (See section 4.9)
The PLT turbine comes with valves and pressure gauge. Unless you buy the discounted
TRG twin pack, camlocks fittings as well as valves and pressure gauge are supplied with the
TRG turbines. All you need to buy is 10m of 50mm ID (2”) flexible hose, and arrange for your
penstock branching to threaded outlets using saddles etc.
2.9.3. Spare jets
Each turbine in supplied with jets cut to the size that was calculated to your design in the
Advanced Calculator. If your original measurements were accurate then these will work
well, you can also close valves to adjust the flow. You will also get four spare jets that you
can cut to any size (see section 8.3.2).
More spare jets can be ordered with the turbine to save on carriage costs later if you think
you might need them.
