•
Is the machine / system / container connection prepared according to the dimensions
of the dimension sheet / installation diagram?
•
Do the concrete foundations have sufficient concrete strength (min. B 15) per
DIN 1045?
•
Is the concrete foundation hardened?
•
Is the surface horizontal and even?
3.3.2
Installation and set-up of the side channel blower
Side channel blowers are always placed with their feet on a base plate and are fastened
with screws.
For assembly on a foundation, the side channel blower must be aligned with a spirit level.
3.3.3
Connecting the pipelines
•
For short pipelines, the nominal widths should at least match those of the side channel
blower connections. For longer pipelines, determine the most cost-effective nominal
width from case to case.
•
Transition pieces to larger nominal widths should be designed with an expansion angle
of about 8° to prevent increased pressure loss.
•
The suction line rises continuously to the side channel blower. Lay pipelines
continuously falling for the supply to prevent air lock from forming.
•
Depending on the type of system and side channel blower, installation of backflow
prevention valves and shut-off elements is recommended.
•
Expansion of pipelines due to temperature must be countered by suitable measures.
We recommend installing compensators directly between the side channel blower and
the pipeline.
Stability - risk of injury!
Side channel blowers with large drives that are installed vertically are top-
heavy. These side channel blowers must be secured against tipping during
assembly or disassembly, for example by using retaining ropes.
Note!
The side channel blower must never under any circumstances be used as a
point for securing the pipeline. No forces or moments (for example caused by
warping or heat expansion) from the pipelines may be allowed to affect the side
channel blower. Pipes must be intercepted directly before the side channel
blower and connected with no tension. Suitable compensators should be used
when doing this.
Caution - risk of injury!
If pipeline forces are exceeded, points with faulty seals may develop on the
side channel blower itself or on the flange connections, which may result in
powerful ejection of conveying medium.
