Pump system
A pump system configured to deliver drilling fluid in at least one of a driving well and a drilling well includes a pump unit, a rotary drive device configured to drive the pump unit, and a gearbox comprising a driving gear and an driven gear. The rotary drive device is operatively connected to the pump unit by the gearbox.
1. A pump system configured to deliver drilling fluid in at least one of a driving well and a drilling well, the pump system comprising:
a pump unit comprising a pump unit housing;
a single rotary drive device configured to drive the pump unit; and
a gearbox encasing a driving gear, a driven gear, and an intermediate gear, the gearbox extending longitudinally along a side of the pump system, and the driving gear being configured to rotate around a driving gear axis, the driven gear being configured to rotate around a driven gear axis, and the intermediate gear being configured to rotate around an intermediate gear axis,
wherein the rotary drive device is operatively connected to the pump unit by the gearbox, and each of the driving gear axis, driven gear axis and intermediate gear axis are arranged so as to substantially lie in a same horizontal plane.
2. The pump system as recited in claim 1 , wherein the rotary drive device includes a single shaft end to which the driving gear is rotationally connected.
3. The pump system as recited in claim 2 , further comprising at least one of a clutch and an elastic clutch, wherein the driving gear is connected to the single shaft end by at least one of the clutch, so as to selectively establish a rotationally fixed connection between the driving gear and the single shaft end, and by the elastic clutch, so as to establish a permanent rotationally fixed connection between the driving gear and the single shaft end.
4. The pump system as recited in claim 1 , wherein within the gearbox, the driving gear and the driven gear are helical gears.
5. The pump system as recited in claim 1 , wherein the rotary drive device is arranged at least at almost a same level as the pump unit.
6. The pump system as recited in claim 1 , wherein each of a shape, a size and an arrangement of the rotary drive device has a width (B) which is substantially the same as a width (b) of the pump unit.
7. The pump system as recited in claim 1 , wherein the rotary drive device has an extension (L) arranged in a direction of the width (B) of the pump system.
8. The pump system as recited in claim 1 , wherein the pump unit further comprises a pump drive shaft.
9. The pump system as recited in claim 8 , wherein the pump drive shaft is not a crankshaft of the pump unit.
10. The pump system according to claim 8 , wherein the driven gear is connected to the pump drive shaft.
11. The pump system as recited in claim 8 , wherein the pump unit further comprises a crankshaft with a crankshaft gear wheel, and wherein the pump drive shaft includes a pump drive shaft gear wheel, the crankshaft gear wheel and the pump drive shaft gear wheel being configured to mesh with each other.
12. The pump system as recited in claim 8 , wherein the pump unit further comprises a housing.
13. The pump system as recited in claim 12 , wherein the pump drive shaft is configured to protrude out of the housing.
14. The pump system as recited in claim 12 , wherein the rotary drive device includes a rotary device housing, and the rotary device housing and the pump unit are at least substantially adjacent to one another.
15. The pump system as recited in claim 1 , wherein the gearbox is surrounded by a gearbox housing.
16. The pump system as recited in claim 1 , wherein the gearbox includes a slip-on gear.
17. The pump system as recited in claim 1 , wherein the pump system is provided as a modular design with modules comprising the pump unit, the rotary drive device and the gearbox, each of the pump unit, the rotary drive device and the gearbox being surrounded by a housing.
18. A pump system configured to deliver drilling fluid in at least one of a driving well and a drilling well, the pump system comprising:
a pump unit comprising a pump unit housing;
a single rotary drive device configured to drive the pump unit; and
a gearbox encasing a driving gear and a driven gear, the gearbox extending longitudinally along a side of the pump system, and the driving gear being configured to rotate around a driving gear axis and the driven gear being configured to rotate around a driven gear axis,
wherein the rotary drive device is operatively connected to the pump unit by the gearbox, and each of the driving gear axis and the driven gear axis are arranged to lie in a same horizontal plane.
