Top ViewThe Automatic Lubrication System consists of the following systems:
Electrical system
Air system
Lubrication systemThese systems work together. The electrical system turns the automatic lubrication system on and off at periodic intervals. The air system connects the electrical system to the lubrication system. The air system is used to pressurize the lubrication system. The lubrication system provides the flow of the lubricant to the bearings.The electrical system activates automatic lubrication solenoid valve (3) at specific time intervals. When valve (3) is activated, system air pressure is allowed to flow to air regulator (2). The air regulator limits the amount of air pressure to pump assembly (1) .The pump assembly pressurizes the lubricant. Vent valve (8) is operated by the regulated air supply. The vent valve allows the pressurized lubricant to flow to the injector banks. The injector banks distribute the lubricant to the bearings. The lubrication injectors are adjustable.Vital Information Management System
Machines that are equipped with the Vital Information Management System (VIMS) do not have a separate electronic control for sending the signal to the air system. The VIMS sends the signal to the air system. The automatic lubrication system also contains pressure sensor (11) for monitoring the pressure of the lubricant.Note: The automatic lubrication system on machines that are equipped with the VIMS is only active when the engine speed is greater than 1000 RPM.System Components
