56 | November - December 2017 | www . machinerylubrication.com significantly impact the system's cost. A ventability test will identify the supply-line diameter required for a specific grease. It can also assist in determining whether the grease can be used in a centralized lubrication system and whether grease valves and injectors will function properly. e test pressurizes grease to 1,800 psi in a 25-foot coil. After the grease has stabilized at 1,800 psi, a relief valve is opened and the pressure gauge is read after 30 seconds. Matching this pressure reading to a supply- line reference chart will provide the diameter needed. Also, when choosing a supply line, be sure to select an appro- priate material. Some metals, such as copper and galvanized steel, can have severe effects on the grease's composition. It should also be noted that when grease is subjected to certain condi- tions under pressure, it can undergo what is called cake-lock. is occurs when the grease thickener's movement is restricted, leading to a block in the line or component. e base oil may still flow, but the thickener will not. Without the thickener, the base oil may not reach the working zones of the components, thus creating lubricant starvation. All three parts of a grease (the base oil, additives and thickener) can contribute to cake-lock, and no single element can increase or decrease the possibility of the condition. With the results of these tests, you should now have the necessary information to make an informed decision. Consider your budget for a centralized system when making your grease selection but design the system around the grease. Avoid common mistakes such as having a supply-line diameter that is too small or too large, using too much or too little pressure to push grease through the supply lines, and sacri- ficing essential grease properties just so the lubricant can flow through the system. Now, if you are asked which comes f irst when designing a centralized lubrication system, the system or the grease, you'll know the right answer.
