1.04 DESCRIPTION OF THE COMPRESSOR BLOCK:
The compressor block
PACIFIC 23
has a range of use for high pressure air up to a maximum of 330 bar (4700 psi). The
compressor consists of three stages driven by three pistons. The first stage is in the center, the second is on the right
(fig.1) and the third is on the opposite side.
The compressor block is a single body unit including several intermediate separators that are placed between the
cooling serpentines (inter-cooler) of the various stages. The flywheel of the compressor does not require balancing
because it is made of ultra-light alloy materials while the compressor has a crankshaft complete with counterweights that
eliminate vibration due to dead times or non-compression times.
The movement of pistons is transmitted through the connecting rods using roller bearings. The roller bearings have a
high workload and as a result the mechanism is very strong. Cylinders are made in aluminum with a barrel in cast iron
inside.
This allows the machine to be the most technologically advanced product available in the market.
The main advantage is
that the cooling fins dissipate heat much faster and is more resistant to corrosion, compared to cast-iron.
The machine has a large capacity oil storage sump of 3,5 liters, a gear oil pump for forced-feed lubrication followed by
an oil filter and a magnet that holds back all the iron particles inside the sump. This way the oil will remain clean which in
turn makes the machine more reliable.
