SYSTEM 011 – SINGLE
LINE PROGRESSIVE
A
centralized lubrication system is defined as progressive sequence type when it
contains metering valves which carrying out the work of having pistons moving in
their seats, they drive another one with an interdependent sequence and deliver
a predetermined quantity of lubricant to user whose number corresponds to the
number of distribution elements. In other words a flow generator (pump) is
placed at the origin of the system; this then is connected to a metering valve
working in such a way that it meters and delivers the desired quantity of
lubricant to the first user; when this action is fulfilled, the sequence goes on
for the second user and so on for the next ones. Each metering valve is put in
series with all the others located after or before it. The failure of anyone of
the metering valves causes all the others to shut down. In case of external
obstruction in the supply lines to the bearing causing a piston to stop, this
will obviously shut down the whole system. Lubricant: oils up to 2000cSt/40°C
and greases up to grade 2 (ASTM).
