Embodiment Construction

[0027] The drawing shows a subsea delivery unit 1 with an outer pressure housing 2 and a module housing 3 arranged in the pressure housing, said pressure housing consisting of two housing parts 21, 22, so The module housing 3 accommodates a pump 31 and a drive 32 with a coupling 33 . The drive device 32 and the coupling device 33 are sealed against the ingress of process media by blocking media. The module housing 3 is supported at its right-hand end on a fixed bearing 24 of the second pressure housing part 22 and is provided with a swivel connection for the electrical and hydraulic supply lines 5 . The pressure housing 31 is mounted axially displaceably on the left side in the inlet connection 25 , so that the left end of the module housing 3 is designed as a floating bearing. Two flanges 23 , 26 are arranged on the pressure housing 2 , via which flanges a connection to the pipeline system can be produced.

[0028] The module housing 3 is arranged in the pressure housing 2 ...

Abstract

The invention relates to an underwater delivery unit with a pump and a drive device that is sealed against the surrounding water and a process medium. According to the invention, the pump (31) and the drive device (32) are combined into a module with a module housing (3) and are arranged in a pressure housing (2), wherein the pressure housing (2) is filled with the process medium and surrounds the module housing (3).

Description

technical field [0001] The invention relates to a subsea delivery unit with a pump and a drive, wherein the drive is sealed against the surrounding water and against the process medium. The invention is particularly suitable for conveying multiphase mixtures. Background technique [0002] DE 37 21 398 A1 describes a delivery unit consisting of a pump and a drive, wherein the pump is surrounded on all sides by a pump housing which has a suction chamber with a suction opening and A pressure chamber with a discharge port. The pump housing is designed watertight and is connected to an equally watertight motor housing that accommodates the drive unit and encloses a motor chamber that surrounds the encapsulated drive unit and is relatively opposite to the motor housing. The suction chamber is separated liquid-tightly. The motor chamber is filled with a plugging medium, in this case oil, which serves to lubricate bearings, possibly gears or the like and to load the seals and to ...
