The advantages of centralized lubrication system over manual lubrication:

1. Automatic system guarantees timing and automatic lubrication, which saves labor (95%) and ensures operators’ safety.
2. By forced and timing lubrication with fixed quantity for fixed points, centralized lubrication system is clean and grease-saving. Save grease for more than 70%, environmentally sustainable.

The advantages of centralized lubrication system over manual lubrication:

3. Compared to manual lubrication, centralized lubrication system is enclosed, which avoids grease leaking and the abrasion of friction pairs.
4. Your machine is well greased, which extends the service interval, thus lengthening working time and enchancing your efficiency.
5. Expand your machines’ lifespan for more than 60%.


System Analysis:

Autol Intelligent Centralized Lubrication System

With computer, automatic control, wireless data transmission and centralized lubrication technology, this system is a new intelligent solution characterized with smart centralized management, remote online monitoring and environmental protection. Compared to timing lubrication with fixed quantity, this system supplies lube with an improved model which is distribution by needs with appropriate quantity at proper time. Besides, the pump ability has been improved.

Advanced Technologies:

Online monitoring: collect, inquire and store the data of the system; give a fault alarm, find the operation failure, provide fault analysis, eliminate fault to make sure the system efficient, safe and convenient.
With automatic controlling technology, the pump can supply lube automatically and efficiently.
By monitoring each lube points, the system can precisely adjust the operation diameters which guarantees environmental and saving lube distribution by needs with appropriate quantity at proper time.
The integration of network, automation, sensing technology and lube system makes sure the equipment work well. If anything goes wrong, the system will find and address promptly to avoid equipment damage.


PLC, pumps, solenoid directional valve, smart distributor, pipe and accessories, monitoring and controlling system, etc.

  • 1.Programmable Logic Controller(PLC)

    PLC controls the electric elements of the lube system by programming. The data of the PLC can be displayed by touch screen
    Provide DC24V, AC380V, AC220V 50Hz electricity;
    Adjust supply parameters and display the system;
    Control grease station and protect the system;
    Control model: automatic and manual operation
    Alarm signals: high or low liquid level, block, leakage, fault
    Communication method: RS-485
    Supply cycle:adjustable
    Supply time:adjustable
    Supply volume:adjustable
    Material: stainless
    Style: double-door, enclosed type, rain-proof and dust-proof

  • 2.Electronic Oil Feeding Pump

    When the oil level in the lube pump is low, PLC will send start signal to the oil feeding pump and it starts feeding the lube pump till the high liquid level.
    Main Technical Parameters:
    Nominal pressure: 2.5 MPa
    Output: 200 L/h
    Capacity: 270 L
    Power: 1.1kw
    Voltage: AC380V
    Operating temperature: 20℃~+100℃
    Lube: NLGI 0 #-2#

  • 3.Solenoid Directional Valve

    Through solenoid directional valve, the oil feeding pump can feed the lube pump with automatic direction change.
    Main Technical Parameters:
    1. Nominal pressure: 20 MPa
    2. Power: 30W
    3. Max Output: 3 L/min
    4. Direction change frequency: 30 times/min
    5. Operating temperature: 0-50℃

  • 4.Intelligent Distributers

    In the system, intelligent distributer carries out the last step of the lubrication. Receiving the signal sent by PLC, the smart distributer controls the solenoid valve to move so that there is a path between supply line and lube points, which makes it possible for the lube to be delivered to lube points. Meanwhile, the distributer collects the signals of the flowmeter, send them to PLC, which makes sure data collection and problem solving.
    Components: smart controller, volumetric flowmeter, solenoid oil feeder, pipe, tie,etc.
    1. Volumetric flowmeter monitors the supply of each point on real time, avoiding the bad effects made by pressure, distance and temperature, etc.
    2. Double controlling modes can avoids failure better than one controlling mode.
    3. The working condition of the system can be seen through smart controller, which is convenient for fault inquiry.
    4. Smart controller can control each solenoid valve, which is convenient for fault inquiry and problem solving.
    Main Technical Parameters:
    1. Electricity: DC24V
    2. Outlet number: 3--5
    3. Communication method: RS-485

  • 5.Pipe and Accessories

    Supply line
    Through supply lines, an electronic pump delivers high-pressured lube to the inlets of each distributors.
