K95400 Lincoln Ventmeter
Centralized automatic lubricating systems are designed to deliver the right amount of grease at the right time to prevent too much or too little lubrication. These systems pressurize grease, deliver it to the needed sites and then vent the system to relieve pressure. The proper grease is essential for the system to function correctly. The grease needs to flow under the applied pressure at the temperature of the system and recover with venting so that it can be pressurized again. This test uses a Lincoln Ventmeter to measure ventability of grease under conditions similar to those used in industrial systems
The Lincoln Ventmeter incorporates a 25-foot long, 1/4 inch diameter pipe with a pump to pressurize the grease and a valve to vent the grease. The apparatus is filled with grease and brought to the required test temperature. The system is stabilized at 1800 psi and then vented. After 30 seconds the residual pressure is read and reported. In general, greases with readings of less than 400psi vent pressures are typically acceptable for use in automatic lubrication systems.
