Embodiment Construction

[0044] Figure 1a A schematic section through an embodiment of a multistage pump according to the invention is shown, which is generally designated by reference numeral 1 . The multistage pump 1 is designed as a centrifugal pump for conveying liquid from the pump inlet 7 to the pump outlet 6 .

[0045] In the following description of a preferred embodiment of the multistage pump 1 according to the invention, reference is made exemplarily to a configuration in which the multistage pump 1 is designed as a horizontal cylindrical casing pump with a multistage casing, ie as a double Cartridge case pump. The multistage pump can be designed, for example, as pump 1 of pump type BB5.

[0046] It is to be understood that the present invention is not limited to this embodiment. The multistage pump can be designed, for example, as a vertical multiphase pump.

[0047] The multistage pump 1 comprises a cylindrical housing 4 and a plurality of stages 3 each having an impeller 34 for conve...

Abstract

The invention relates to a pump for conveying a fluid, comprising a cylindrical housing and a pump shaft which is arranged in the interior of the cylindrical housing and which is rotatable about an axis, having an impeller which is arranged on the pump shaft in a torque-proof manner for acting on the fluid, the pump further has a pump inlet for supplying fluid to the interior space and a pump outlet for discharging fluid from the interior space, one end of the cylindrical housing is closed by a cover, and the pump comprises a clamping device for fixing the cover to the cylindrical housing, the clamping device comprising a clamping element and a clamping device which can be arranged in a bore of the clamping element, the clamping element includes first and second abutment surfaces. The clamping device is movably arranged relative to the clamping element along a clamping axis such that, in a mounted state of the cover, the clamping element is clamped between the cylindrical housing and the cover by cooperating with the clamping device, in which mounted state a clamping force is exerted on the cover by the cylindrical housing via the first abutment surface to the second abutment surface such that, in the mounted state, the clamping element is clamped between the cylindrical housing and the cover by cooperating with the clamping device. The cover is fixed to the cylindrical housing by a clamping force.

Description

technical field [0001] The invention relates to a pump with a cylindrical housing according to the preambles of the independent claims. Background technique [0002] Multistage pumps for conveying fluids are used in many different fields, especially in applications where high pressures are to be generated. Important industries using multistage pumps are eg the oil and gas processing industry, the power generation industry, the chemical industry, the cleaning and wastewater industry or the pulp and paper industry. [0003] In the oil and gas processing industry, multistage pumps are designed, for example, to transport hydrocarbon fluids, such as extracting crude oil from oil fields or transporting oil / gas through pipelines or within refineries. Another application is the injection of process fluids, which in most cases are water, and especially seawater, into oil reservoirs. For this application, the pumps are designed as (water) injection pumps, which deliver seawater at h...
