2.1.
INTRODUCTION
The pump is a compressed air
driver pump used to transfer the refrigerant from refigerant tank
to the refrigerant charging machines in the case that both of them
are far apart.
The compression ratio of the pump is
3.*5 times the compressed air pressure.
2.2.
DESCRIPTION
The pump has a dual effect
refrigerant cylinder, driven by a dual effect air
cylinder.
The refrigerant pipes are terminated
with check valves for the correct working, and a manometer is
located close to the output quick connection in order to check the
output pressure.
A safety overpressure valve is
present on the output side in order to recirculate the gas in case
of misoperations in compressed air adjustment.
In the compressed air circuit is
present a pressure regulator with the relevant manometer, in order
to adjust and check the correct operation of the unit. A
lubrication unit is used to lubricate only the air cylinder, in
order to guarantee the correct movement.
A special filter
is located at the output side of the air cylinder driver valve.
This is to avoid that the nebulized oil goes out from the
silencers. The residual oil is collected in the bottom part of this
filter. The user has only to check the level regularly and remove
the oil when the level is too high.
It is
important to guarantee the correct liquid gas supply to the pump.
Make sure the inlet piping is correctly dimensioned. It is a
correct procedure to add a gas filter in the inlet line, to
guarantee that no dirty can go inside the pump, causing problems in
its operation.
