Manual for BAUER RAINSTAR A1, A2
8
2 DESCRIPTION
RAINSTAR A1, A2 is appropriate for sprinkling golf courses and sports grounds, seed crops and
horticultures, parks as well as all kind of grassland.
The main components are a two-wheel undercarriage, the reel with the special PE-pipe, the compact
gearbox and the TCN 10 turbine as well as the high-rise cart with the BAUER small- and wide-range
gun.
The material of the PE-pipe corresponds to the latest state-of-the-art. One end of the pipe connects to
the reel drum and to the water supply through its axle. The other end of the pipe is coupled with the
high-rise cart. The cart's track width is infinitely adjustable (see technical data).
The heart of the RAINSTAR A1, A2 is the TCN 10 turbine. This is a turbine, nearly insensitive to soiled
water and offers maximum efficiency. The drive shaft is made of stainless steel. The nozzle inside the
turbine is made of wear-proof plastic.
The lifetime lubricated drive shaft bearing is sealed by a maintenance-free rotating mechanical seal.
The TCN 10 turbine is designed for water flow rates from 3 to over 20 m³/h and features a wide control
range. Impeller speeds range from 200 to 1600 rpm.
The system's connecting pressure should not exceed 8 bar.
Power is directly transmitted from the turbine to the change-speed gearbox as well as from the chain
drive onto the reel. A reel brake prevents fast reverse rotation of the reel in the final shut-off position
when the PE-pipe is stretched.
The reel brake and the gearwheels in the gearbox filled with oil, act as brake and prevent the PE-pipe
windings on the reel from loosening during pipe pull-out.
For safety reasons, the drive is fitted with an emergency stop and a reversing stop. With this emergency
stop device, the drive can be stopped immediately by hand.
Never remove the drive cover before you have turned off the water supply
to the machine and slackened the stretched PE-pipe.
A winding carriage moved by a helically grooved spindle ensures that the PE-pipe is wound up properly
on all layers.
