Abstract

A mobile lubrication pump has a motor for driving the pump for producing a pump pressure, a pressure monitor for measuring the pump pressure, a motor controller for regulating the operation of the motor, and a data processing unit (DPU) for communicating with the motor controller, and for receiving: 1) input from the pressure monitor, and 2) user input related to pump capacity and/or lubrication target. The data processing unit is configured to determine and communicate a motor speed and/or motor torque to the motor controller based on the received input 1) and 2).

Claims (34)

1. A mobile lubrication pump, comprising:

a motor for driving the pump for producing a pump pressure;

a pressure monitor for measuring the pump pressure;

a motor controller for regulating the operation of the motor;

a data processing unit (DPU) for communicating with the motor controller, and for receiving: 1) input from the pressure monitor, and 2) user input related to: a maximum lubrication pressure of a lubrication target; and

wherein the data processing unit is configured to determine and communicate a motor speed and/or motor torque to the motor controller based on the received input 1) and 2).

2. The pump according to claim 1 , wherein the user input is further related to a target pump pressure of the pump.

3. The pump according to claim 1 , wherein the DPU is configured for continuously receiving input from the pressure monitor.

4. The pump according to claim 1 , wherein the DPU is configured for minimising the difference between input 1) and 2).

5. The pump according to claim 4 , wherein the DPU is configured for minimising the difference in a closed feedback loop.

6. The pump according to claim 1 , wherein the motor controller is configured for regulating the operation of the motor continuously.

7. The pump according to claim 1 , wherein the motor controller is configured for regulating the operation of the motor discontinuously.

8. The pump according to claim 1 , wherein the DPU and the motor controller are an integrated unit.

9. The pump according to claim 1 , wherein the user input is received via a communication device.

10. The pump according to claim 9 , wherein the communication device is a wireless device.

11. The pump according to claim 10 , wherein the communication device is a tablet or a smart phone or a laptop.

12. The pump according to claim 10 , wherein the communication device is a device configured with near field coupling or Bluetooth.

13. The pump according to claim 1 , wherein the user input is obtained via a scanning device configured for reading a label associated with the pump capacity and/or lubrication target.

14. The pump according claim 1 , wherein the user input is received manually.

15. The pump according to claim 14 , wherein the user input is received via a panel or a potentiometer.

16. The pump according to claim 1 , wherein the pressure monitor is placed in an open circuit.

17. The pump according to claim 1 , wherein the pressure monitor is a pressure sensor.

18. The pump according to claim 1 , wherein the pressure monitor is a pressure-derived pump parameter.

19. The pump according to claim 1 , wherein the motor is an electric motor.

20. The pump according to claim 1 , further comprising a power supply.

21. The pump according to claim 1 , wherein the pump is selected from the group of: piston pump, gear pump, and rotating piston pump.

22. The pump according to claim 1 , with the proviso that the pump is not a piston pump.

23. A method for regulating the pump pressure of a mobile lubrication pump, comprising the steps of:

a) providing a mobile lubrication pump comprising a pump, a motor, and a pressure monitor;

b) providing at least one condition parameter via a communication device, wherein the condition parameter is related to: a maximum lubrication pressure of a lubrication target;

c) measuring the pump pressure;

d) determining and regulating the speed and/or torque of the motor based on the input in b) and c).

24. The method according to claim 23 , wherein the method is computer implemented.

25. The method according to claim 23 , wherein the condition parameter is further related to a target pump pressure of the pump.
