Questions and Answers
What is the purpose of the variable inlet vanes installed upstream of each blower?
The variable inlet vanes restrict airflow to prevent overloading the blower motor.
How are the P-122A/B-1 (C-120A/B Main Lube Oil Pumps) powered?
They are crankshaft driven positive displacement pumps.
What happens if the P-122A/B-1 main lube oil pumps fail?
The P-122A/B-2 auxiliary lube oil pumps will route the lube oil to the compressors.

Study Notes
Compressors Lube Oil and Crankcase Oil Supply System
-
D-130 Lube Oil Storage Drum: Common storage for lube oil used in C-120A/B and C-360A/B compressors; dimensions of 2’6”D x 7’L.
-
Equipped with a plate coil and Roto-Meter for low-pressure nitrogen purge, venting through a 1-1/2” vent at the top.
-
Lube oil flows in from the top and exits from the bottom, while low-pressure nitrogen enters through the top and vents out.
-
E-130 Lube Oil Drum Plate Coil: Maintains lube oil temperature within D-130 using 60 psig steam as a heating medium.
-
P-130 Lube Oil Transfer Pump: Air-operated barrel pump routes lube oil to C-120A/B and C-360A/B compressors; mechanical device designed to move liquids through piping.
-
D-140 Crankcase Oil Storage Drum: Storage for crankcase oil, shared by C-120A/B and C-360A/B; also measures 2’6”D x 7’L and features a plate coil.
-
Crankcase oil enters the drum from the top and exits from the bottom. Low-pressure nitrogen also enters the top for pressure maintenance.
-
E-140 Crankcase Drum Plate Coil: Similar to E-130, it uses 60 psig steam to keep the crank oil temperature regulated inside D-140.
Compressors Motor Purge System
-
F-121 Purge Air Filter: Comprises 24 filter assemblies, each with a prefilter and main filter to eliminate particulates from incoming air.
-
C-121A/B Purge Air Blowers: Include inlet guard screens, variable inlet vane controllers, and blowers are powered by 50 HP motors. Each unit equipped with a hand/off/automatic switch and local indicator light.
-
The variable inlet vanes prevent blower motor overload by manually restricting airflow; only one blower operates during normal conditions.
C-120A/B Crankcase Oil and Cooling Water System
-
P-122A/B-1 C-120A/B Main Lube Oil Pump: Crankshaft-driven positive displacement pump ensures consistent oil flow to compressors.
-
P-122A/B-2 Auxiliary Lube Oil Pumps: Centrifugal pumps activated if main pumps fail; driven by 10 HP induction motors at 1750 RPM, providing backup lubrication.
-
E-122A/B-1 and E-122A/B-2 Lube Oil Coolers: Multi-tube U-type heat exchangers that cool lube oil with water; installed to maintain suitable oil temperatures.
-
F-122A/B-1 and F-122A/B-2 Lube Oil Filters: Essential for removing contaminants from lube oil, ensuring system integrity.
-
FI-123A/B-1 and FI-123A/B-2 Packing Cooling Water Filters: Filters that maintain cleanliness in the cooling water used in conjunction with C-120A/B compressors.
C-120A/B Rod and Cylinder Lubricator System
- P-121A/B Lubricator Pumps: Camshaft-driven piston pumps delivering lubricant to the rod packings and cylinders of C-120A/B; powered by 10 HP induction motors.
