Nitrogensystem
Thenitrogensystemcanbeusedinanumberofdifferentways:
nitrogen is used as
dilution gas. It is injected inside the cylinder on
two different places. Nitrogen flow injected in the middle hole is
preset at 2 l/ min and can be adjusted with valve DGR 2,
depending on the application. Nitrogen flow injected in the hole on
cylinder endplate side is preset at 10 l/ min and can be adjusted
with valve DGR 1, depending on the application. When flow is too
low a warning then an alarm signal is generated by flowmeter DGF
to the PLC. Status of the pump depends on the alarm function set
by user (factory setting : None, pump continues running with an
alarm). Dilution improves the screws functioning, especially when
sucking corrosive gases.
