General Operation - Automated Lubrication System
(ALS) - Truck
The Lubecore™ Automated Lubrication System (ALS) can be equipped with several options
and a variety of pump styles. This section describes the general operation of a standard
pneumatic lubrication pump with standard components. For details regarding the operation of
our other pumps and components, please refer to the appropriate Lubecore manual or contact
Lubecore directly. A Lubecore parallel automated lubrication system consists of the following
main components.
Note: The ① are identification markers referring to items in the illustration on the next page.
- ① Pneumatically operated pump
- ② Electronic timer.
- ③ Manifold and ④ injector assemblies.
- ⑤ Primary and ⑥ secondary tubing with fittings.
A Lubecore automated lubrication system will be designed and assembled according to the
specific type of equipment and the associated operating conditions. Starting with the
manufacturer specifications regarding the lubrication requirement, the system layout will be
designed and the appropriate components will be selected.
The standard automated lubrication system is designed to function as follows:
While the equipment is in operation, the ignition switch provides the power for timer operation
② with battery power to perform its program. The timer’s internal memory retains the last
status prior to shut down. At start-up, the program resumes and counts down the time that
remains in the predetermined interval.
After reaching the end of the pause interval, the timer engages a solenoid located on the bottom
of the pneumatic lubrication pump ①. The activation of the solenoid provides the pump with air
pressure (100 psi minimum) from the on-board air tank ⑧.
In turn, the pump, pumps the maximum allowable amount of grease, under pressure, into the
mainline tubing ⑤ that connects the pump to either one or more manifolds, which are located at
centralized point on the equipment.
The moment maximum pressure is reached in the mainline tubing, injectors ④ located in the
manifolds ③ begin to measure and dispense a predetermined and consistent amount of
lubricant through the secondary tubing ⑥ and fittings ⑨ and into the lubrication points ⑩.
Once 40 Bar/580 PSI is reached, the pressure switch ⑪ closes and makes a connection to
ground. This indicates to the timer that the system operating pressure has been obtained. The
pressure switch then signals to the ALS that the lubrication cycle has been completed
successfully.
At the completion of the lubrication cycle, the solenoid is deactivated by the timer. Air pressure
from inside the pump is then directed to a pressure relief valve on the right side of the pump ⑫.
The relief valve contains a spring set to keep a maximum of 5 psi / 0.3 bar pressure over the
outside air within the pump. The purpose of this design is to prevent corrosion and other
