Describe the primary function of the P-361A/B-1 (C-360A/B Main Lube Oil Pumps) within the context of the compressor lubrication system.
Describe the primary function of the P-361A/B-1 (C-360A/B Main Lube Oil Pumps) within the context of the compressor lubrication system.
The primary function of P-361A/B-1 pumps is to route the lube oil to the C-360A/B compressor.
Explain how the recycle cylinders are cooled, contrasting this method with the cooling approach used for the booster cylinders.
Explain how the recycle cylinders are cooled, contrasting this method with the cooling approach used for the booster cylinders.
Recycle cylinders are cooled using a closed thermosiphon system with glycol, while booster cylinders utilize cooling water routed to the inner head, booster cylinder jacket, and outer head.
What is the purpose of using a mixture of glycol and water in cooling jackets within static systems, and under what conditions is this system typically employed?
What is the purpose of using a mixture of glycol and water in cooling jackets within static systems, and under what conditions is this system typically employed?
The glycol and water mix ensures uniform heat distribution within the cylinders. It's used when gas temperature change (AT) and discharge temperatures are less than 150°F and 190°F, respectively.
In the event of a failure of the main lube oil pumps (P-361A/B-1), what system is in place to maintain lubrication during start-up and stand-by service, and what type of pump is used for this purpose?

Study Notes
- Crankcase oil flows from D-140 to C-360A/B Crankcase Frame Oil Reservoirs as make-up.
- P-361A/B-1 (C-360A/B Main Lube Oil Pump) sends crankcase oil to the shell side of either E-361A/B-1 or E-361A/B-2 (C-360A/B Lube Oil Coolers).
- Cooling water cools the oil on the tube side of the lube oil coolers.
- P-361A/B-2 (C-360A/B Auxiliary Lube Oil Pumps) provide start-up and stand-by service.
- Crankcase oil goes to either F-361A/B-1 or F-361A/B-2 (C-360A/B Lube Oil Filters) before lubricating compressor parts.
- Crankcase oil returns to C-360A/B Crankcase Frame Oil Reservoirs.
- Cooling water is routed to the inner head, booster cylinder jacket, and outer head of the booster cylinders.
- Recycle cylinders use glycol in a closed thermosiphon cooling system.
- Cooling jackets in static systems typically contain a glycol and water mix for consistent heat distribution within the cylinders.
- This system can be used when the gas temperature change (AT) and discharge temperatures are below 150°F and 190°F, respectively.
- Thermal siphons use temperature differences between hot and cold coolants to create flow.
- A thermal siphon system is suitable when the gas temperature change (AT) and discharge gas temperature are less than 150°F and 210°F.
- Lube oil is supplied from D-130 to C-360A/B Compressor Cylinder/Packing Oil Reservoir.
- P-362A/B (Lubricator Pumps for C-360A/B) provides lube oil to internal lubrication points
- A hand-operated auxiliary pump is available as a backup.
