What is this?

-Where liquid is received from the storage tank, pressurized, and discharged to the vaporizer.

-Consists of liquid end housing, piston, cylinder, inlet and outer bail valves (check).

What is this?

-A region between the warm end and the cold end.

-Serves as a heat barrier.

-It is necessary to maintain proper cold en temperature and prevent freezing lubricant in the warm end.

What is this?

-Formation of a gas pocket in the inlet chamber of a cryogenic pump, resulting when the temperature of the pumped liquid rises above its boiling point.

What is this?

-The cooling of a liquid below its boiling point to prevent evaporation loss and pump cavitation.

-Usually accomplished by increasing the pressure of the cryogenic liquid.

What is the normal O2 pressure?

What is the normal N2 pressure?

*game show voice*

NAME. THAT. COMPONENT.

Location: Mounted on the charging unit skid next to the pump.

Physical Appearance: Cylindrical, squirrel cage design.

Construction Features: Induction type, 15 HP, AC motor.

Functional Operation: Provides the driving force for the cryogenic pump.

*game show voice*

NAME. THAT. COMPONENT.

Location: Two single pulleys are keyed to shafts, one on the motor output and one on the pump input.

Physical Appearance: Gear type pulleys and belt.

Construction Features: A drive belt connects the two pulleys.

Functional Operation: Transfers driving force of the motor to the pump.

NAME. THAT. COMPONENT.

Location: Located in the thermal isolation region.

Physical Appearance: 2 sets of chevron packing, springs and oil scrapers.

Construction Features: Chevron packing, teflon and brass.

Functional Operation: The cold seal keeps the cryogenic fluid form leaking into the warm end and the oil scrapers keep oil in the warm end from entering the cold end.

*game show voice*

NAME. THAT. COMPONENT.

Location: In the liquid and drive end, threaded into the cross-head.

Physical Appearance: One piece piston and piston rod, three seal rings, one rider ring.

Construction Features: Hollow with a ball valve inside.

Functional Operation: Allows cryogenic liquid to enter on the suction stroke. On the inlet stroke the inlet ball retracts, allowing the cryogenic liquid around it to enter the cylinder. The discharge remains rested on the discharge port. On the discharge stroke the inlet ball is seated and the piston overcomes the discharge system pressure allowing the discharge ball to unseat, thereby allowing the liquid to flow into the liquid discharge port.

NAME. THAT. COMPONENT.

Location: In the liquid end.

Physical Appearance: Cylindrical.

Construction Features: Has a ring bleed hole for the release of excess gas generated by the vaporization of the cryogenic liquid.

Functional Operation: Cryogenic liquid enters the cylinder through the liquid inlet port via the piston, and is forced through the liquid discharge port by reciprocating piston movement,

*game show voice*

NAME. THAT. COMPONENT.

Location: In the cryogenic pump suction line.

Physical Appearance: Wire mesh filter.

Construction Features: 10 micron nominal, washable, wire mesh filter.

Functional Operation: Prevents solid contaminant such as ice, packing, and insulation from entering cryogenic pump suction.

*game show voice*

NAME. THAT. COMPONENT.

Location: Power end housing.

Physical Appearance: Includes bearings, shaft assembly, connecting rod, crosshead assembly, and wrist pin. Crankshaft supported by two spherical roller bearings.

Construction Features: Bearing are interference fitted to the shaft and not repairable. Eccentric drive cam assembly is keyed and interference fitted to crankshaft and not repairable.

Functional Operation: Rotary motion of the bearing shaft assembly is transformed to reciprocating motion of the connecting rod, which drives the crosshead and piston.
