Abstract

A suction chamber for use in a horizontal fluid pumping system is supported by a fixed vertical bracket, which is attached to a platform. The suction chamber is positioned between a motor and a pump in the horizontal pumping system. The pumping system may also include a thrust bearing chamber positioned between the motor and the suction chamber. The pumping system may also include a bearing chamber adapter positioned between the thrust bearing chamber and the suction chamber. The suction chamber has a suction chamber pump end and a suction chamber motor end. The suction chamber enables both motor-end seal removal and pump-end seal removal. In both motor end seal removal and pump end seal removal, the suction chamber of the invention remains connected to the vertical bracket. The pumping system may also include an integrated lifting device connected to the vertical bracket to lift the thrust bearing assembly.

First claim

What is claimed is:

1. A horizontal pumping system comprising:
a motor;
a pump driven by the motor;
a platform;
a thrust bearing assembly connected to the motor;
a suction chamber assembly, wherein the suction chamber assembly comprises:
a vertical bracket extending from the platform;
a suction chamber connected to the pump and supported by the vertical bracket, wherein the suction chamber includes a motor-end plate that has a central opening;

a bearing chamber adapter connected between the thrust bearing assembly and the suction chamber, wherein the bearing chamber adapter comprises an adapter pump-end plate removably attached to the motor-end plate of the suction chamber with fasteners that are accessible from outside the suction chamber;
a seal assembly inside the suction chamber, wherein the seal assembly is removably connected to the adapter pump-end plate of the bearing chamber adapter with fasteners that are accessible from inside the suction chamber; and
wherein the seal assembly is sized to be removed from the suction chamber through the central opening of the motor-end plate of the suction chamber when the adapter pump-end plate is removed from the motor-end plate.

2. The horizontal pumping system of claim 1 , wherein the suction chamber further comprises a pump end plate connected to the pump.

3. The horizontal pumping system of claim 2 , wherein the pump end plate is removable from the pump.

4. The horizontal pumping system of claim 1 further comprising:
an integrated lifting device connected to the vertical bracket and configured to remove the thrust bearing assembly from the horizontal pumping system to provide access to the seal assembly in the suction chamber.

5. The horizontal pumping system of claim 4 , wherein the integrated lifting device comprises:
a first member connected to the vertical bracket;
a second member connected to the first member at a pivot point, wherein the second member is capable of pivoted rotation about the first member; and
a trolley slideably engaged with, and removable from, the second member.

6. The horizontal pumping system of claim 5 , wherein the trolley further comprises:
a lifting member; and
a mechanism for lowering and raising the lifting member.

7. The horizontal pumping system of claim 6 , wherein the mechanism for lowering and raising the lifting member comprises a crank attached to the lifting member.

8. The horizontal pumping system of claim 6 , wherein the thrust bearing assembly may be lifted or removed from the horizontal pumping system utilizing the integrated lifting device.

9. A horizontal pumping system comprising:
one or more platforms;
a motor supported by the one or more platforms;
a pump supported by the one or more platforms;
a vertical bracket supported by the one or more platforms;
a suction chamber connected between the pump and mounted directly to and supportable by the vertical bracket, wherein the suction chamber includes a motor-end plate that has a central opening;
a thrust bearing assembly, the thrust bearing assembly comprising:
a thrust bearing chamber connected to the motor;
a bearing chamber adapter connected between the thrust bearing chamber and the suction chamber assembly, wherein the bearing chamber adapter includes an adapter pump-end plate that is removably connected to the suction chamber; and
a thrust bearing chamber bracket supported by the platform and connected to the thrust bearing assembly;

a seal assembly, wherein the seal assembly is removably connected to the adapter pump-end plate of the bearing chamber adapter with fasteners that are accessible from inside the suction chamber; and
wherein the seal assembly is sized to be removed from the suction chamber through the central opening of the motor-end plate of the suction chamber when the adapter pump-end plate is removed from the motor-end plate.

10. The horizontal pumping system of claim 9 , wherein the pump is removably connected to the suction chamber.

11. A horizontal pumping system comprising:
a motor;
a pump driven by the motor;
a thrust bearing assembly connected to the motor;
a suction chamber assembly, wherein the suction chamber assembly comprises:
a suction chamber connected to the pump, wherein the suction chamber includes a motor-end plate that has a central opening; and
a seal contained within the suction chamber, wherein the seal has a seal body with a greatest outer diameter and wherein the greatest outer diameter of the seal body is smaller than the central opening of the motor-end plate; and

a bearing chamber adapter connected between the thrust bearing assembly and the suction chamber, wherein the bearing chamber adapter comprises an adapter pump-end plate removably attached to the motor-end plate of the suction chamber with fasteners that are accessible from outside the suction chamber and wherein the seal body is connected to the adapter pump-end plate with fasteners that are accessible from inside the suction chamber.

12. The horizontal pumping system of claim 11 , wherein the seal is a cartridge seal assembly within the suction chamber assembly.

13. The horizontal pumping system of claim 11 , wherein the seal is a component seal assembly within the suction chamber assembly.

14. The horizontal pumping system of claim 11 , wherein the suction chamber assembly further comprises:
an inlet pipe; and
a nozzle.
