Submersible hydro turbine generators
are standard serially produced units. It
is a low head propeller design. Reaction
turbines require a much larger amount of
water flow than impulse styles, but can
operate with as little as two feet of
head, making them ideal for sites where
there may be relatively flat land, but a
large water flow. They use either a
'traditional' reaction style runner
(propeller runner).a specially designed
outlet tube increases the turbine power
output by creating suction as the water
exits the system.

In order to provide optimal performance
over a wide range, eight (8) different
fixed guide vane angles are available.
Runners are available with either four
(4) blades. The runner blade angles have
been set at the best degree. Induction
generator is designed for submersible
applications.
The turbine and generator are integrated
into a single unit ready to be lowered
down into simple compact structures. In
a hydro turbine generator all components
in the unit are designed to function
together from the beginning. There are
no transmission shafts to align when
installing. Draft tubes, seats are
prefabricated steel units, ready to be
cast into the structure. While running,
the generator is cooled by water flowing
around it.
The construction is simple and fast;
in most cases old structures can be
adapted for use with small changes. The
hydro turbine generator is not bolted
into the structure. It is simply lowered
down to a bottom seat for installation
and it can be easily hoisted up for
inspection and service. The
submersible concept dramatically
minimizes the impact on the environment,
especially on the landscape, because
most of the structure is placed either
in the waterway or underground. In some
applications the whole station is
hidden, by being placed below the water
surface. No more dominating power
houses. But don¡¯t pull down old
beautiful mills or stations, put the
submersibles under them and use the
place in them as a museum or for other
activities.
It is the most cost-efficient micro hydro concept!
1. Key Technical Data:
Water Head for installation:1.5—3.2m
Flow (m3/s):0.025---0.055
Output Voltage (v): 230V(AC)
Output Power (kw): 0.55
2. Station Site and Installation:
1) The site should be chose according to the flow and drop of water source.
Commonly, the drop should not be less than 3.2m. A water storage pond can be
build when the flow is not enough, storing at daytime and generating at night,
but
the volume should not be less than 15-25m.
2) The unit should be installed in the place where it is convenient to charge
and
no danger of flooding. It is much better to install close to the user¡¯s house
(the
best way is to install within house-yard when possible) in order to manage well
and reduce the investment for power transmit line.
3) The base structure may be built from local material. You can make a round
hole which has the diameter as same as the lower inner circle of the turbine
frame
by using cement, wood-board, etc, and fasten it in screw or round nail, also it
should be positioned horizontally.
3. Operation Method:
1) Firstly, check whether all components are completed and the intake of
penstock is blocked.
2) Then check whether the runner of turbine can be easily rotated, and rotated
in by hand to ensure the voltage meter has readings (put the output switch in
OFF
position).
3) For the first starting, the output switch should be put in the
voltage-stabilized
control position (A), then open the gate to let water out from small to large,
observe the readings meter till 220v or so continue enhancing water volume, the
voltage device is reliable if the reading keep still. At this time the load can
be
connected, then adjust the water volume to hold the output of 220v or so. Once
the stabilizing device break down, put the switch in B, then the voltage of unit
will
be under manual-controlled, you may follow the next procedure to control by
valve.
4) During the operation, the load should be kept stable as possible as can be.
Don't shut off the load suddenly, or else the high voltage will burn out the
rest
load, if you must is connect the load, you may decrease water to small volume at
first, then disconnect the most part of load when the voltage has dropped to
below 220v (you must do as this even you run the unit under the using of
voltage-stabilizing device).
5) It need only close the valve to switch off the unit when the load has been
stable after first operation, the power switch may hold on so that you may
adjust
voltage up to 200-220v directly for next running.
