| The Liquid
Oxygen Pump is a single acting piston pump. It is used
for filling Oxygen into Cylinders upto a pressure of
165 kgs./cm2.
| The pump is designed for assembly
in air separation unit that works by pumping liquid
Oxygen and gasifying the same in Heat Exchangers
for final filling as gas in Cylinders. Control
of liquid feed is not necessary, because the pump
is designed in accordance with the plant size
and the liquid produced is constantly pumped off.

SANGHI
- ORG Liquid Oxygen Pump |
The drive unit is similar to any reciprocating machine
with the Crank Shaft, Flywheel, Connecting Rod, Cross
Head, etc.
The Liquid Oxygen Pump consists of a stainless steel
inside liner with liquid inlet and evaporated gas outlet
ports. There are no valves on these ports, which are
closed by the piston itself on the pressure stroke.
The third outlet is the main discharge outlet with the
two non-return ball valves. The two ball valves remain
firmly closed during suction stroke, due to high pressure
in partly filled cylinders. To ensure that these valves
are fully closed, a positive pressure of about 60 kgs/cms2
must be maintained on it. When a fresh batch of cylinders
is taken for filling, open the manifold valve slowly
or use a spare batch of cylinders to ensure positive
pressure on these valves. |
