Life at the end of the road

XJ14-0. 2DCT4-Z

Filed under: daily doings, hydro — lifeattheendoftheroad @ 9:28 pm

Not the catchiest of titles for the days post but it’s there so I can find it easily in WordPress’s cr4p search facility in months to come 🙂 And no it’s not a car by Jaguar but a hydro turbine by Navitron http://www.navitron.org.uk/index.php that now sports a much snappier name WAT200WHHT or Water 200watt, high head turbine. The man who came up with that obviously has a military background 🙂 far more sensible.

Anyway, I digress, it was an early start today as we had to be away on the first ferry to go and pick up my boy and his pal who’d been stranded on the mainland with the weather. It was their first day back at school today after the hols, and whilst they probably would not have missed a great deal my boy’s had so much time off school recently due to the snow I was determined to get him in for a few hours at least. So the pigs got fed in pitch blackness at 6:30 and half an hour or so later we were heading down a vastly thawed out ‘Calum’s road’ with a trailer full of dustbins. School is not the only thing that gets disrupted by the friggin snow 🙂

The trip to Kyle and back was uneventful but it took up a huge slice of the day, so on returning home around midday I got straight into some fencing. A few days fencing work that I’d started in November and not been near since due to the snow and festivities.

It’s only a couple of hundred meters of fence but due to the terrain and number of gates it’ll require about a dozen strainers. Each strainer needing to go down around a meter in the soft ground like this and at least a couple of feet in the rock. I say soft but the ‘soft’ ground here was littered with quite large stones that made the bottom of the hole too large. A straight or slightly tapering hole is essential, any enlargement at the base will cause your post to rock so I opened it up much wider than all the others I’d done so far. I’d managed to fill the other posts in with local stone but there’s not much suitable at the site and it had left me with quite a large hole to fill.

I set off on the quad with a couple of coal sacks and fish boxes for suitable stones, as using the trailer was out of the question. The last time I’d taken the trailer up there my camera had ended up in a bog under the wheel of the quad

After loading a good few stones on the quad I tried a different route up trying to avoid the ‘camera eating bog’. The trouble with heather is that it can hide very large rocks 😦 and here’s my mates quad perched on top of one with all four wheels off the ground 🙂

Anyway, after much swearing and see sawing I got free and managed to get my ex telegraph pole firmly attached to Scotland just by that ancient rowan tree. At a guess I’d say it was 150 years old because it’s around the same size as this one https://lifeattheendoftheroad.wordpress.com/2008/03/11/poor-old-rowan/ that I cut down behind the house. These trees were often planted near houses to ward off evil spirits and they say it’s bad luck to bring it in the house. Now there’s certainly no sign of a dwelling up there but this tree must have been fenced in at one time or it would simply have been eaten by the sheep or deer.

I just got the post done in time as I had to head down the road to pick up my boy from school, it was on the way home that we saw this beauty with nine points on his antlers.

He’s in fine condition and it says something for my Panasonic DMC FZ38 that it took this picture at 18x optical zoom in poor light without a tripod. OK, I did rest the camera on my sons head but it had not long since been removed from a peat bog 🙂 My half a dozen previous Fuji’s would break if you sneezed 😦 Yes I’m sure your Fuji has been just boodly marvellous but I take my camera everywhere, not just on holiday in a padded bag 🙂

Navitron 200w water turbine dismantling

Now this is going to get really boring ladies so I suggest you visit    http://stonehead.wordpress.com/ or http://www.isleofrona.com/ or http://exceptthekylesandwesternisles.blogspot.com/ unless you’re interested in the guts of a  XJ14-0. 2DCT4-Z hydro turbine. Unfortunately I spent the rest of the evening before my http://www.charlesmacleod.co.uk/haggis.aspx and neaps stripping one down 😦

Now I fitted this wee turbine a few years ago, more as an experiment than a serious attempt at generating any meaningful power and I have to say that it surpassed all my expectations.

200W Powercurve High Head Turgo Water Turbine – Navitron

Retail Price: £ 351.80 (excl. Vat)
                    £ 422.16 (incl. Vat)

Qty

200w high head

The 200w high head water turbine is based on a turgo wheel runner which operates in free air. The turbine is supplied with a removable jet, which can be adapted for installation at sites with higher head of water. Even with the standard jet, the turbine may be used at higher or lower head, although the output power will vary accordingly.

High Head Further Info

Mine was considerably cheaper, around £350 inc VAT and delivery to Raasay, but even at £422 it’s still a bargain if you have a good steady water flow. The quality isn’t great but there’s nothing that can’t be sorted with a little DIY skill. This is most definitely not a ‘fit and forget’ unit, for that you have to pay ten times more but it does do exactly what it says on the tin 🙂

Anyway mine became redundant when I fitted a multi nozzle ‘Stream engine’ from  http://www.microhydropower.com/ in September so I recently removed it from its shed down by the shore to overhaul it and use it on another project.

100111 024

The first thing was to remove the turgo runner which is secured to the 15mm shaft by two M6 bolts accessed by a 10mm socket through the jet hole. With these two bolts removed you can draw off the runner by screwing an M10 x 75mm bolt into the threaded end of the steel runner. Or at least you should be able to, mine was so tight that the bolt sheared and I had to re tap it 😦

With that off you can remove the dump load which is attached by two screws that won’t come out but it’s easy enough to bend the brackets out of the way.

100111 017

After which you’ll have to cut that plug off in the centre of the picture as it won’t fit through the hole in the control box or turbine housing.

100111 019

It’s a pretty pathetic affair and the insulation had gone on mine but as I said, it’s cheap 🙂

100111 020

Three M6 bolts hold the housing on to the PMA and three M5 bolts hold the end plate on to the stator.

 

100111 027

The rotor can be a little bit of a struggle against the powerful magnets but there are no brushes or slip rings to damage.

100111 028

The bearings are pretty standard, the top one being 15mm inside dia, 35mm outside dia and 11mm wide. The lower one is slightly bigger at 17, 40 and 12

100111 029

and this 17x35x10 seal keeps out the water.

100111 021 100111 023 100111 022

The turgo is approximately 144mm in diameter, has 12 spoons, is 90mm tall and fits on to a 15mm shaft.

100111 026

The top bearing can actually be changed with the unit in situ by simply removing three M5 bolts, lifting off the top and then drawing the bearing off the shaft.

As you can see it’s a little rough around the edges, there’s nothing to stop water getting in that top bearing and the unit was full of Chinese grease. The turgo runner is pretty poorly made of welded mild steel and mine was pretty well corroded with all the peaty acid water. It is however a solid bit of kit, that with a little work, some decent bearings and a good coat of paint should last for many years.

    • Hi Administrator,
      that is indeed a great blog and makes me feel ten years younger 🙂

      Cheers, Paul

  2. I recognise that table cloth Paul. Either you’re messing about with your bits and bobs in the kitchen or you’ve swiped the cloth. Either way does Mrs P know 🙂
