The sump

Windmills are typically used to pump water from a borehole up to 180m in depth.  Another application is putting the pump into a sleeve that sucks water from a dam or river and push it up to a reservoir.

The borehole pump can be installed not higher than 6m from the water source and can push the water up to 180m head up (vertical) and 24km in distance (horizontal).

Pumping from a river or a dam

Apart from the Turbex windmill pumping from a bole hole, it also pumps water very successfully from a river, a fountain or a dam.

This is done by installing the Turbex windmill on a nice suitable spot next to the river, fountain or dam.  As long as the level of the intake suction point of the pump does exceed about 6m in height from the water level in the river, fountain or dam, the Turbex can be installed quite a distance from the dam or river.  With the pump at the Turbex  connected via a thick walled plastic pipe to a suitable suction point in the river or dam, the pumping action works exceptionally well.

The pump is normally installed in the center of the tower in a Turbex sump type that allows the discharge head to function at the natural ground level, while the pump inlet also exit at that level.

Electricity from Windmills

Turbex windmills can also be used to generate electricity.
What you will need:
• Turbex windmill
• Turbex generator
• Turbex controller
• Battery bank

How does it work?

A Turbex windmill can be connected to a generator that will output electricity. The controller then regulates the charging of the battery bank. Electricity can then be used to drive various electrical circuits and ancillary equipment. Through an inverter 220V alternating current can be supplied to external circuits.

Systems available:

  • T460
    • 1.5kW system
    • 3.3m diameter windmill head
    • 24V or 48V system
    • 8kWhr generated per day on average
  • T550
    • 3.0kW system
    • 4.6m diameter windmill head
    • 24V or 48V system
    • 15kWhr generated per day on average

The average per day is based on the average wind conditions of the Free State.

The beauty of the machines is that we can pump water and generate electricity simultaneously.

Advantages of the Turbex rotary windmill

A Rotary Pump

Every Turbex windmill use a modern pump called a helical rotary pump that is driven by the wind. This pump rotates whilst the traditional wind pump operates with a reciprocating (up-and-down) motion. The helical rotary pumps are the leading bore hole pump type in South Africa today.

Advantages of Rotary Windmills Other wind powered systems find it difficult to match the Turbex’ performance under the same conditions.

A Turbex windmill will pump more water

The Turbex windmill pumps more water for smaller installations which dramatically reduces the pumping costs. Take a typical example. A Turbex Wind Turbine with a 4.6 diameter wheel, operating in a 20 km/h wind and installed on a borehole 30 m (100ft) deep, will deliver 30 000 liters of water per day. That is almost 11 000 000 litres per year!

Deeper water

Getting water at great depths was uneconomical in the past. The Tubex has now made it a feasible reality. The manufacturers of the rotary borehole pumps certify that these pumps can operate at depths of up to 200 – 240 m. Very few, if any, other wind driven units can reach these depths.

Pumps water for kilometres

You can install the Turbex windmill at the water source and pump it to wherever you need it. Even the smallest Turbex windmill will maintain a pumping rate of 1000 liters/h over a distance of 15 km in a typical wind speed of 20 km/h using a 40 mm pipeline.

Irrigation

If you have access to a dam, channel or river you can use the Turbex windmill for irrigation purposes. A Turbex Wind Turbine with a 5.5 diameter wheel, operating in a 20km/h wind pumping from a river or dam will deliver 12 000 liters/h. In strong winds this can go up to more than 40 000 l/h.

Reliability

The Turbex windmill is as reliable as it is effective.

The following features make these machines especially reliable:

  • The Turbex windmill automatically feathers out of strong winds to prevent over speeding and can absorb gusts of wind without damage.
  • The wheel is exceptionally strong and can withstand wind velocities of up to 80 km/h. The unique tower is designed for strength
  • The machine tracks the wind’s changing direction.
  • The Turbex windmill can withstand harsh weather conditions such as heat waves, storm winds, snow, rain, icing, and corrosion for many years.
  • Long life bearings ensure low maintenance.

The following conclusions can be made about Turbex windmills

  • Of all the types of water pumping systems available, the Turbex windmill is by far the cheapest per litre pumped over 15 years.
  • The Turbex pumps more water than other alternative energy systems.
  • The Turbex is even cheaper than pumping water with electricity. That is not taking in account the cost of laying a new power line.
  • The diesel driven pumping system is so expensive that it can normally only be used for emergency situations

There are many different pumps and pumping systems which can pump water from a borehole. Every system has advantages and disadvantages. You can only make the right choice of product if you can compare the advantages and disadvantages of all that is available.

Storm wind protection of Turbex.

The windmill is designed to protect itself against over speeding of the rotor during storm wind conditions.  The tail of the machine will turn the rotor side ways in such storm wind conditions automatically.  It is always a good idea to put the machine on break when such storms are approaching.

Maintenance and reliability

Here follows a list of maintenance requirements that has to be performed on the Turbex Windmill.  As far as reliability is concerned, the Turbex has almost no equal in the windmill markets. Due to the well proven helical rotary bore hole pump that is installed with the Turbex, maintenance is reduced to absolute minimum.

Where the traditional reciprocating windmill requires regular maintenance of its cylinders, shafting and pipes in the bore hole, the rotary pump of the Turbex requires much less maintenance. As far as pipe lines are concerned, the Turbex requires no air chambers at the windmill’s outlet or it’s pipe lines. With the traditional reciprocating windmill, wind chambers are essential to absorb the pressure fluctuation of it’s reciprocating pumping action.

List of regular maintenance requirements:

1. Monthly service of the glad packing on the discharge head.  (Ask our installer to show you how this simple step can be accomplished in less than 15 minutes.

2. Every three month greasing of the wooden block and the bearings on the head and discharge head.

3. Check the bolts and nuts on the tower.

4. Replace the oil in the gearbox every 2 years.

5. Replace the borehole pump every 7 to 10 years depending on the amount of sand in your borehole.

Sand in the bore hole.

After the completion of a newly drilled bore hole, there normally are an amount of dust and sand at the bottom of the bore hole.  This is the reason why one normally don’t install a pump right up to the bottom of the bore hole, but leave at least 3 m at the bottom for such remnants of the drilling process.

There can also be sand in the bore hole due to other reasons, like for instance some place down the bore hole where the sides falls in.  The driller would normally put a bore hole casing into the bore hole to a depth where he reckons the formation down the hole is solid.  If this was not done properly, sand from the sides of the bore hole that keeps falling down, will be suck up by the newly installed pump, which can totally damage such pumping equipment.

Function of the quick release coupling.

The helical rotary pumps that are installed with the Turbex windmill were designed to only turn anti-clock wise.  That mean that the drive shaft from the Turbex gearbox of the machine only turn in one direction.  If something causes the drive shaft to turn in a clock wise motion, it might unscrew the line shaft any where between the discharge head and the pump n the bottom of the hole.

Apart from the fact that the drive shaft in such an event will be lose, it is quite an exercise to take the pipes and rods out of the bore hole to find the place where the rod  unscrewed.

The quick release coupling was designed to prevent such an event from taking place.  It also has the function to disconnect the drive shaft in the tower from coupling with the discharge head.  The discharge head is fitted with a v-belt pulley to be used when one wants to drive the bore pump with an engine

The procedure to do such a change over from wind power driven to engine driven, is to put the windmill on break, then undo the quick release coupling.

The pulley on the discharge head is now ready to be fitted with the v-belt of you motor or your engine.
