Abstract

The present application relates to a lubrication system (S) comprising dosing means (1-1) for feeding lubricant to a lubrication point. The invention is based on the idea that computerized control means (1-5, 1-6) are arranged to control the operation of the lubrication system (S). The dosing means (1-1) are configured to operate responsive to a control signal provided by the control means (1-5, 1-6) to adjust the amount of lubricant to be fed by the dosing means (1-1, 1-2) to a lubrication point as required by the control means, wherein the amount of lubricant can be adjusted lubrication-point-specifically.

Claims

1. A lubrication system comprising:

dosing means configured for feeding lubricant to a lubrication point within an apparatus to be lubricated and monitored in conjunction with a monitoring part located at the lubrication point;

the dosing means are configured to operate responsive to a control signal provided by computerized control means to automatically adjust a volumetric amount of lubricant to be fed by the dosing means to the lubrication point, without requiring input from a user of the system and without requiring manual adjustment of the lubrication system by the user of the system, as required by the control means, wherein the amount of lubricant is adjustable to be specific to the lubrication point;

the control means are configured to receive a signal input from the monitoring part within the apparatus to be lubricated, the signal input including information on the condition of the apparatus to be lubricated, such that the control means are configured to adjust the amount of lubricant fed by the dosing means to the lubrication point on the basis of the condition of the apparatus as measured at the lubrication point;

means for receiving an input provided by the user of the system, the input including information on at least one lubrication parameter, wherein the control means are configured to adjust the amount of lubricant fed by the dosing means to the lubrication point on the basis of said input provided by the user as a supplement to automatic adjustment by the computerized control means of the dosing means.

2. A system as claimed in claim 1, wherein the system is configured to adjust the amount of lubricant to be fed by the dosing means by adjusting the dosing time.

3. A system as claimed in claim 1, wherein the system is configured to adjust the amount of lubricant to be fed by the dosing means by adjusting the dosing rate.

4. A system as claimed in claim 1, wherein the system is configured to adjust the amount of lubricant to be fed by the dosing means by adjusting the dosing interval.

5. A system as claimed in claim 1, wherein the control means are configured to control the dosing means to dose lubricant to a specific lubrication point continuously or when needed.

6. A system as claimed in claim 1, wherein the system further comprises a monitoring unit for monitoring the lubrication of the respective lubrication point.

7. A system as claimed in claim 1, wherein the control means are configured to receive the signal input from monitoring part of the apparatus, wherein the signal input represents at least one of a temperature measurement, a vibration measurement, and a power measurement.

8. A system as claimed in claim 1, wherein the control means are configured to adjust the amount of lubricant fed by the dosing means to the lubrication point on the basis of information on at least one production parameter of the apparatus to be lubricated.

9. A system as claimed in claim 1, wherein the system is configured to recognise a predetermined lubrication-related event related to a lubrication point, and adjust the amount of lubricant to be fed by the dosing means to the respective lubrication point on the basis of said event.

10. A system as claimed in claim 1, wherein the system further comprises means for adjusting the lubrication parameters of an individual lubrication point and/or of a group of lubrication points.

11. A system as claimed in claim 1, wherein the system further comprises means for adjusting the lubrication parameters of an individual doser and/or of a group of dosers.

12. A system as claimed in claim 1, wherein the system further comprises means for operatively connecting the lubrication system (S) to a large-scale lubrication system capable of performing a centralized monitoring and/or control of lubrication of several apparatuses to be lubricated.

13. A system as claimed in claim 1, wherein the lubrication point further comprises a bearing, a sliding surface and/or a gearwheel and/or some other object of lubrication of the apparatus.

14. A lubrication system comprising:

a doser for supplying lubricant to a device,

a control system configured to provide a signal to the doser representative of the lubrication required by the device,

a monitor configured to provide a signal representative of a lubricating condition of the doser and an operating condition of the device to the control system, wherein

the control system is configured to interpret the lubricating condition of the doser and the operating condition of the device to, if necessary, automatically adjust the lubrication supply to the device, the control system also being configured to receive an input from a user and adjust the lubrication supply to the device based on the user.

15. A lubrication method for a system having a doser for feeding lubricant to a lubrication point within an apparatus, wherein the method comprises:

receiving, in the doser, a control signal provided by a control system, the control system being capable of controlling the lubrication system;

monitoring by the control system of a parameter of a condition of the apparatus at the lubrication point, wherein the control system adjusts the control signal to automatically adjust a volumetric amount of lubricant to be dispensed by the doser based on the parameter of the apparatus at the lubrication point such that the control system is configured to automatically adjust the volumetric amount of lubricant fed by the doser to the lubrication point on the basis of the condition of the apparatus,

monitoring by the control system for input from a user, wherein the control system is also capable of adjusting the control signal to adjust the volumetric amount of lubricant to be dispensed by the doser based on the input by the user,

in response to receiving the control signal, adjusting the volumetric amount of lubricant to be fed by the doser to the lubrication point within the apparatus.
