Abstract

A vacuum pump (10) includes a control device (20) for processing operational data and operational instructions. Further, the vacuum pump (10) includes a touch screen (40) serving as display for displaying the operational data callable from the control device (20) and as input for inputting operational instructions into the control device (20). The touch screen (40) includes a display panel (42) and a key panel (44) as display and the input, respectively, and is connected with the control device (20) via a data line (36). By combining the display and the input in a single device, namely the touch screen, the trouble for display and data input is reduced.

Claims

1. A vacuum pump comprising:

a control device for processing operational data and operational instructions,

a display for displaying the operational data callable from the control device, and

an input means for inputting operational instructions into the control device,

the display and the input means including;

a touch screen connected with the control device via a data line and comprising a display panel as the display and a key panel as the input means.

2. The vacuum pump according to claim 1, further including:

a program memory which includes a program for generating an operational surface on the touch screen.

3. The vacuum pump according to claim 1, further including:

a separate operational unit which comprises the touch screen which is connected with the control device via the data line.

4. The vacuum pump according to claim 3, wherein the operational unit is mobile and the data line is configured so as to be detachable for removing the operational unit.

5. The vacuum pump according to claim 1, charactcrizcd in that wherein the key panel comprises a start key for starting the pump operation and a stop key for stopping the pump operation.

6. The vacuum pump according to claim 1, wherein the key panel comprises keys for inputting a nominal rotary frequency.

7. The vacuum pump according to claim 1, wherein the display panel comprises a temperature indication for indicating an operational temperature.

8. The vacuum pump according to one of claim 1, wherein the display panel comprises a rotary frequency indication for indicating the actual rotary frequency.

9. A vacuum pump system comprising:

(a) at least one vacuum pump unit, each vacuum pump unit including;

a control device,

sensors for sensing actual pump parameters, the sensors being connected with the control device,

an interface means connected with the control device;

(b) a mobile operational unit including;

a touch screen having a display panel for displaying pump parameters, the display panel defining touch keys through which an operator inputs information,

a means for temporarily interconnecting the touch screen with the interface means to (1) display actual pump parameters sensed by the sensors and (2) communicate operating instructions input through the touch keys to the control device.
