Blower Engineering Instructional Manual

4.3 Direction of rotation – air flow direction
Fig. 6
WARNING:
Do not use the blower with a direction of rotation or a flow direction which
differs from that shown in figure 6.
4.4 System piping
The diameters of the system piping must never be smaller than the diameters of the blower openings.
If the diameters are different, use a taper connector. The system piping should be properly aligned
and supported to prevent placing stress on the blower. Provide flexible joints. The pipes must be
thoroughly cleaned before connection. The gaskets must not interfere with the gas system.
WARNING:
Remove the protective covers from the blower openings before connecting the pipes.
4.5 Check valve
To stop the counter-rotation of the blower when it stops while loaded, install a check valve on the
discharge, when acting under pressure, or on the inlet when acting under vacuum conditions.
4.6 Safety valve
To limit the maximum operating pressure of the blower use a safety valve on the discharge, when
acting under pressure, or on the inlet when acting under vacuum conditions.
WARNING:
Install the safety valves as close as possible to the inlet/outlet at the blower,
without placing shut-off valves in-between.
4.4.1 Inlet pipe
•
Connect a silencer directly to the inlet of the
blower.
•
Thoroughly clean.
•
If necessary install a dirt filter for the first
100 working hours.
•
Install a pressure gauge to check the dirt filter.
•
Support the pipe.
4.4.2 Outlet pipe
•
Connect a silencer directly to the outlet
of the blower.
•
Support the piping at the point nearest
to the flexible coupling.
•
Insulate the pipes so as to avoid heating
the environment and as a precaution to
accidental contact.
