russjohn Posted July 16, 2012 Share Posted July 16, 2012 Hi, I am thinking of using wind power, ie a windmill, to pump water from one lake to another - I am thinking conventional windmill rather than modern wind turbine. Has anyone any experience of trying this and does anyone know where I could get one made. I live near Korat. I would really appreciate any input that others may offer. Thanks in advance. 1 Link to comment Share on other sites More sharing options...
slapout Posted July 16, 2012 Share Posted July 16, 2012 Standard windmills and their associated lift type pump, are not capable of high volume transfer of fluid. The lift system works on a fairly short stroke (18 inch +_) and pump is normally less than 2 inch in size. Even with a good wind ( 25 to 30 mph ) I doubt that the pump rate is much more than 5 gallon per minute. This is going back in memory several decades, so if someone points out errors, I have made, you might want to heed their advice. Link to comment Share on other sites More sharing options...
kwonitoy Posted July 16, 2012 Share Posted July 16, 2012 I'm going by memory back 5 decades also, We had one on our farm in Canada to keep the stock tank filled, and that's about all it could do on a very windy day. Barely a trickle coming out of it and it was sited on a good well I would image that their are more efficent models out there nowadays but I don't think they'd be capable of moving large volumes of water. It will be interesting to see if you can come up with something though, I've got a remote site I use an electric submersiable pump along with a gen set for irrigation in the dry season and a windmill would be nice.

sjefrie Posted July 16, 2012 Share Posted July 16, 2012 I have no experience but i know in Holland they have a " Bosman molen " http://www.bosman-water.nl/english/products/pagina.php?cat_id=751&pagina_id=643 Its partially build with carparts ( rear axle with differential ) Cambodian windmill with rope pump Link to comment Share on other sites More sharing options...
russjohn Posted July 16, 2012 Author Share Posted July 16, 2012 Thanks for your input guys - sounds like a "no-go". i will do a little more research and post my results. Cheers Link to comment Share on other sites More sharing options...
billd766 Posted July 17, 2012 Share Posted July 17, 2012 I worked in NZ a rew years ago and saw quite a few windmills there so I did some Googling and came up with these links that may help. All except the last one will only such up tp 7.5 metres but the last one is Canadian and is supposed to do about 30 metres. I hope they help you. http://www.windmills.biz/ http://www.windmills.biz/main.html http://www.colonialenergy.co.nz/wind.htm http://www.lifestyleblock.co.nz/lsb-forum/showthread.php?t=16752 http://www.horizonwindmills.co.nz/ http://www.technologydevelopmentpartners.org/apecdb/wind/waterpumpingframe.htm Link to comment Share on other sites More sharing options...

tim armstrong Posted July 30, 2012 Share Posted July 30, 2012 They are used extensively in Australia to keep cattle trofs full. Indeed they are everywhere. Try Southern Cross Windmills in Oz they may have some useful ideas. Link to comment Share on other sites More sharing options...
jamescollister Posted July 30, 2012 Share Posted July 30, 2012 One thing no one has mentioned, wind, there is none around here. Think unless you are in a coastal region or some where they get a breeze a wind pump is a no go. No chance here, best I get is convection as one side of the house heats faster then the other.

Jim I don't think that is strictly true. Usually either no wind or gale force when rain is on its way. But i am just being pedantic. I really doubt that the wind in Isaan, most of the time at leat, would be able to supply power. Link to comment Share on other sites More sharing options...

True enough, you could pump a lake dry when you get hit with a tropical depression, trouble being it's then you want less water not more.

mozzieslapper Posted July 31, 2012 Share Posted July 31, 2012 I wonder why then the big commercial wind farms in Thailand are in Issan then? Link to comment Share on other sites More sharing options...
Gary A Posted August 1, 2012 Share Posted August 1, 2012 I think windmills are great. All you need is some wind. Here in Loei province where we live, it would be feast or famine. What wind we have here comes in great bursts that would tear a windmill apart or we have no wind at all. Link to comment Share on other sites More sharing options...

jamescollister Posted August 2, 2012 Share Posted August 2, 2012 What about a pump with sunpower? Sent from my GT-I9300 using Thaivisa Connect App Good question, has been brought up before and I have looked around here and Ubon for a real solar supply shop, pumps. lights, water heaters etc, but not seen any. May be some of the Ubon dwellers may know.Thailand with ample sun seems to be a bit slow on Solar. Jim Link to comment Share on other sites More sharing options...
oldestswinger Posted August 3, 2012 Share Posted August 3, 2012 Things are starting to get going on the solar front. A big factory producing solar panels has been located in Korat and the sme company has bought 100 rai near our farm and has just started construction.

slapout Posted August 3, 2012 Share Posted August 3, 2012 The experience I have had with solar, was replacing a windmill system with solar panel/pump due to mechancial problems downhole on the former The solar system provided about the same volume of fulid as a windmill, thus no where near enough for garden/irrigation use.

Boksida Posted August 3, 2012 Share Posted August 3, 2012 (edited) Years ago (late 70s?) there was a windmill manufacturer in Thailand, but I cannot remember their name. They were for pumping from wells and were only partially successful. There was only a crank at the top and no gearbox as found on more expensive overseas models. For the OP's application, he may want to consider the windmills used to transfer sea water to different evaporation ponds as per the salt farms in the Samut Sakhon, Samut Songkram areas. This a paddle wheel arrangement and only good for moving water to ponds at the same elevation or lower. The salt farm ones made here are of totally non-ferrous parts - tower and paddle wheels are wood, sails are canvas, spars are bamboo and drive is by a knotted rope. 20071230_02241 Flickr - Photo Sharing!.htm As an historical footnote, Silom Road got its name from the windmill that used to be there.

Emma117 Posted February 8, 2013 Share Posted February 8, 2013 (edited) Hi, Everyone Glad you guys talking about the windpump . I am doing the wind pump in India - My company licensed maufactory an UK design windpump from May last year . This windpump is quite simple - wind running the turbine rotor -> turbine rotor running the shaft -> shaft running the reciprocating arm which making the wind rods doing up-dowm movement . The design advoid the use of the a complcated gear box to cut down the cost . more than 1000 of this windpump has been installed in more than 20 countries over a period of 20 years. This is the 3.5m rotor wind pump data which ex-factory price is USD 3,668 with 12meter tower Head mteter wind speed @ 3m/s wind speed @ 4m/s water litres/day water litres/day 5 45,000 90,000 10 22,000 45,000 15 15,000 29,000 25 9,000 16,000 30 7,000 13,000 45 4,700 8,000 60 3,000 5,500 75 2,200 4,000 We also have 5mete rotor as choise . You can google ABS WIND PUMP to see our video on YOUTO . Edited February 8, 2013 by Emma117 Link to comment Share on other sites More sharing options...
NeverSure Posted February 9, 2013 Share Posted February 9, 2013 (edited) Hahaha. Differences in lingo. Mills grind grain, pumps er, uh, pump. Either can be done with wind power. We had wind pumps, LOL. We had a miller grind our grain. The wind pumps were for remote locations where electricity wasn't practical. 100 years ago it wasn't available. We used them to fill watering tanks for cattle. The "up down" crankshaft type mechanism is very practical. A single foot valve type can lift water about 50 feet. A double foot valve can lift about 150 feet. Here's a vid of a single foot valve pump, just to give an idea of it. This could be powered by a wind pump with the crankshaft type design.

Lantern Posted February 9, 2013 Share Posted February 9, 2013 Modern windgenerators are built for speed, to produce electricity, Windmills for pumping are built to produce torque. As others have said Southern Cross in Australia make a wide range. Solar can also work, check out the specs here. The top product is the pump.

Emma117 Posted February 9, 2013 Share Posted February 9, 2013 Advanced wind turbines optimise the rotor speed considering many factors including the tip speed ratio and the CP of the blades. This maximises power production and reduces noise The price of solar PV has reduced significantly in recent years – the efficiency of PV reduced by heat and atmospheric dust / surface dirt on the panels Link to comment Share on other sites More sharing options...
