Example Safety measures
Electric
generators
The electric
generator with
hydrogen cooling and
drive from steam or
gas turbine
The above mentioned is related to the
turbines. To enable the access to the internal
correction planes it is sometimes necessary
to use air instead of hydrogen.
But for most generators the duration of run
and maximum rotation frequency are limited
when working in air medium even if there is
no voltage and load. These restrictions must
be observed during the balancing process.
Make sure that the seal is lubricated properly
when working in air medium. Dismounting
of some internal wind breaker plates can be
required to facilitate access to the internal
correction planes. Also make sure that
the dismounting will not cause significant
reduction in the quality of the generator
cooling.
3.4. Laser safety
According to the ISO 60825-1-2009 the tach used in the device bolongs to the 2nd
class of laser equipment. The tach is eqipped with a laser diode of capacity less than
1 mWt and wave length in the range 635-670 nm.
By operating the equipment you should follow special requirements:
- do not open the tach.
- do not observe laser light sources by the powered tach.
- do not direct a laser bearm in the eyes of others.
All repair works, which need the tach to be opened, should be performed only by
specialists of BALTECH GmbH.
3.5. Installation of trial and correction weights
When you add the trial and correction weights make sure they are fixed properly
and can withstand the developing centrifugal force. The correction weights should
not interfere with the normal machine operation. If the installation procedure of the
correction weights is specified in the manufacturer’s instructions, strictly observe
them.
