Powerlift prefabricated pumping station
3.3.5 Installing shaft components with PSD-B
Shaft rings with connection collars, cover plate, supporting rings and cover are supplied loose.
■
Shaft components delivered by ACO
according to/similar to DIN 4034-1 have an
ACO mechanical seal for joint sealing. The
mechanical seal is a compression mechanical
seal with a wedge-shaped cross section and
a factory-made, closed, pre-lubricated slide
sleeve. A load-distributing tube filled with fine
quartz sand is permanently attached to the
sealing ring.
■
The mechanical seal is pre-fitted at the factory
to the spigot end of the shaft component and/or
the tank.
Should the mechanical seal slip out of place e.g. during transportation or on-site, then this
should be tightened again as follows:
Î
On cold days, pre-heat the sealing, e.g. construction tank.
Î
Clean spigot.
Î
Fit the circular rotating mechanical seal to the spigot such that the slide sleeve of the
circular rotating mechanical seal faces outwards and the load-distributing tube lies
centrally on the spigot.
Î
Position the circular rotating mechanical seal on the shoulder and spread the
pre-tensioning evenly.
IMPORTANT
■
Transport eyes on the shaft components are designed for their own weight load. Do not
transport with other shaft components placed on top.
■
After placement, there must be a maximum gap of 15
mm present in the interior.
max. 15 mm
■
Always observe the maximum installation depth of the prefabricated pumping station,
Chapter 6.1.1 “Dimensions”.
