Outside-driven pump |
Due to the appropriate material choice of
the working parts, the FORCYL equipments can
favourably be used even under special
circumstances like being subject to chemical
effects, high temperature, etc. |

WATER
JET ENGINES |
The FORCYL water jet engines
create brand new possibilities in
sailing.
The innovation is that the nozzle
under the water level ejects a high
velocity, rotation-free water jet
in proportion with the rpm, and its
reaction force provides the driving
force.
In FORCYL water jet engines
the water jet is generated by a
special rotating chamber and spindle
rotating into one direction but not
at the same rpm. |

Water jet engine in sailing |
|
The water gets
axially through the rotating elements in the
direction of the nozzle, without whirling.
When discharging the nozzle, the water is
still not whirling. Depending on the rpm the
volume of the discharged water can be
modified.
|
|
The special design of the pump
improves the efficiency of the FORCYL
multi-functional equipments (no whirling
loss, no prerotation). These characteristics
are resposible for the extraordinary
maneuvering abilities. If a rotating
detouring unit is built in the way of the
water jet, the boat can change its direction
between 0-360˚. In small capacity boats
there is no need for an extra rotating
detouring unit because the pump with the
nozzles is fixed in a way that it can turn.

Due to its structure and variable rpm
(10-10000/min) the FORCYL water jet
enginges can be used in all kinds of water
vehicles: from large sea ships to small
sport boats, from shallow to deep dive
vessels.

HYDROMOTORS |
|
The strator of the Moineau
hydrostatic motors is a spiral polygon
elastomer vulcanized in a steel tube. Due to
the deviation in the thickness of the
elastomer unfavourable material fatigue
occurs during operation causing breakdowns
and shortening the life of the motors. |
|
|
Elstomer with different thickness |
Elastomer with equal thickness |
|
|
Using the
new motor technology and equipments Micro
Europe Ltd. is able to preprocess the
polygon form of the bore of the steel house,
thus creating the possibility for
vulcanizing elastomers with almost equal
thickness. The possibility of unfavourable
fatigue becomes smaller and the lifetime of
the motor can be doubled.

Downhole motor - EDM |
In
cooperation with Smith International Inc.
our company developed a new downhole motor
which can work at high temperature and under
agressive circumstances.
The new
downhole motor works with the same positive
volume squeezing technology as the Moineau
motors, but the profile is different, it has
a cyclois surface. The „stator” (chamber)
rotates in the new motor, it rotates in the
same direction as the rotor (spindle) but at
variant speed.
Both the chamber and the spindle are made of
steel which means that the motor does not
contain any elastomer so it is not sensible
to any gasous material or other drilling
fluid containing chemicals.
|
|
The new downhole motor can be designed for
low 100 – 200 rpm, middle 300-400 rpm and
high 800-1000 rpm depending on the
requirements of the drilling tool.
The speed of the motor is directly
proportional to the inlet fluid volume. The
torque of the motor is directly proportional
to the pressure drop in the motor.
The new motor with this profile is called „Epicyclois
Downhole Motor”, EDM.
Our company developed the production
technology of the motor and the necessary
machines and tools. |
