4.2 Part Assemblies
With exception of the Can the pumps are delivered
completely mounted and adjusted; also the shaft seal is
in the correct position. So no further axial alignment of
the rotor is necessary. If drivers and/or seal systems
are delivered separately, follow the assembly
procedure in section 6.9.
Axial alignment and rotor setting axial
adjustment need to be distinguished. For correct axial
adjustment of the rotor refer to 5.3.1 Adjusting of the
rotor.
4.3 Foundation
The foundation shall be located on a place that
allows a minimum of pipe work and that is easily
accessible for inspection during operation. According
to the environment the foundation may consist of
concrete or of steel. It must be rigid and heavy
enough to absorb normal vibrations and shocks. The
flange of the Can must be supported on the whole
surface. It should be at least 20 – 30 mm
(0.8 – 1.2 in) higher than the surrounding to avoid the
deposit of dust and humidity.
4.3.1 Vertical alignment
Vertical alignment is done with leveling screws.
Use a spirit level for correct horizontal alignment of
the baseplate.
The max. vertical misalignment is 0.5 mm/m
pump length.
4.3.2 Steel foundation
When the pump unit is mounted directly on structural
steel frame, it shall be well supported by constructural
beams. It is recommended to check the natural
frequency of the steel frame, because it shall not
coincide with the pump speed. The flange of the Can
has to be fixed on a flat surface with studs or hex
screws, the exact horizontal alignment is very
important!
4.3.3 Concrete foundation
A concrete foundation must have an exact horizontal
alignment and must be placed on solid ground. First
a basic foundation shall be built with square shaped
holes for embedding the foundation bolts. After
putting the Can in the foundation the proper
alignment can be obtained by adjusting it with shims
under the flange. Now insert the foundation bolts and
grout the space between the basic foundation and
the Can with grouting cement (refer to illustration)
It is very helpful to use a properly made and stable
wooden frame around the Can. So the grouting cement
will not flow a side. When the grouting is totally set and
hardened the foundation bolts shall be tightened in a
firm and symmetrical way.
4.3.4 Final assembly for not complete assembled
pumps
Pumps exceeding a total length of approximately 6 m
(19.7 ft) are delivered in various components and
must be assembled on site. The main parts are:
hydraulic bowls section - various line shafts and
column pipes - headstock and thrust bearing.
To install the pump in the Can, clamps for the column
pipes are delivered with the pump.
1) Mount the first rising main column pipe [1350.3]
and line shaft to the already assembled hydraulic
section.
