Flowserve 2564 Mixerpac - Manual (Page 8)

Installation of the MIXERPAC on the machine may take place during machine
breakdown only.
6.2 The MIXERPAC must always be installed with the installation plates engaged.
6.3 Apply a lubricant to the mixer shaft or shaft sleeve, see item 5.8.
6.4 Push and lower the complete MIXERPAC on the mixer shaft.
6.5 Align the MIXERPAC to the positions of the flange and connection bores.
6.6 Continue to lower the MIXERPAC down to the metallic seat in the area of the fastening
screws, and then screw this to the mixer vessel.
!
It is imperative that the centering of the MIXERPAC housing engage in the mixer
vessel’s assembly flange without force. Under no circumstances may the given
fit tolerances be exceeded.
Components provided by the customer for installing the MIXERPAC, e.g. fasten-
ing screws, must prove adequate both in the choice of material and the dimen-
sions. It must not be possible to overstress these components, e. g. the max
permitted tightening torque must not be exceeded.
6.7 Effect the shrink plate connection between the shaft sleeve and shaft. The shrink plate
is stressed as per the installation instructions for shrink plate connections (see item
12.1) over several stages to a tightening torque in accordance with the drawing.
!
The areas for the clamp connections must remain free of grease, otherwise the
holding force will become inadequate for correct functioning.
The shaft sleeve can be displaced in radially or axially direction, if the shrink disc
connection between the shaft sleeve and shaft is not accomplished according the
requirements.
6.8 To disengage the installation plates, loosen the screws, pull out the plates and
retighten the screws.
!
The disengaged installation plates may not contact rotating parts during the
operation of the machine.
6.9 Once more check the running precision as per DIN 28161 and the installation dimen-
sions according the assembly drawing.
The installation dimensions of the MIXERPAC must apply to the dimensions
shown on the assembly drawing. Non-compliance of the information shown on
the assembly drawing may cause in damages.
