7.1 Assembly / disassembly
If pumps or pump units are dismantled for the purpose of maintenance or repair work,
it is the responsibility of the operating company to ensure that the instructions
described in the "Additional operator's manual and assembly instructions" are
carefully observed during reassembly. This applies in particular to the adjustment of
the gap dimensions of rotating/stationary components and to screw tightening
torques, which otherwise present an incalculable risk of ignition due to friction or parts
becoming loose. Correct installation is a prerequisite for explosion protection.
Danger of explosion due to incorrect assembly!
- The mounting/removing of the pump units must be carried out in a
non-explosive environment or in an area without an existing
explosion hazard.
- When mounting/removing the pump units, an explosive atmosphere
inside the equipment must be excluded by the operating company.
- In the case of pump units in which a potentially explosive
atmosphere may occur inside the pump during operation, repair
and maintenance work on housings, covers, seals and conveying
elements may only be carried out by
Fristam
fitters or by personnel
trained by
Fristam
.
Before commissioning, a test run under exclusion of an explosive
atmosphere must be carried out and a test protocol specified by
Fristam
must be drawn up.
- Connect the pump shaft to the motor shaft as described in the
operator's manual.
- Correct alignment of the shafts.
- Correct installation of the coupling and sufficient space between
coupling and coupling protection.
- Gap dimensions and tightening torques are recorded in the
"Additional operator's manual and assembly instructions" of the
respective pump.
- Stress-free integration of the pump into the pipe system.
