Liquid Oxygen Pump:
The oxygen pump is a single stage, single acting piston pump. It is used for filling Oxygen into cylinders upto a pressure of 165/200 kgs./cm2.
The pump is designed for assembly in the 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 unnecessary because the pump is designed in accordance with the plant size and the liquid produced is constantly pumped off.
The drive unit is similar to any reciprocating machine with the crankshaft, flywheel, connecting rod, cross head etc.
The oxygen pump consists of a stainless steel inside liner with liquid inlet and evaporated gas outlet port. 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-Teturn Ball Valves. The two ensure that these valves are fully closed, a positive pressure of about 60kgs cm2 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 a positive pressure on these valves. Most malfunctions of the pump are due to these valves not closing properly.
When the pump is operated Liquid Oxygen from the main condenser enters the outlet jacket of the pump. Some of this liquid evaporates due to heat produced in pumping and the vapour is passed out through the upper port back into the upper column as gas. The main stream of liquid oxygen is taken into the pump cylinder and compressed out by the piston in the pressure stroke. This high pressure liquid oxygen passes through two non-teturn valves into the Heat Exchangers and then to the Cylinder Filling Rack.
