A cleaning device for a vehicle, with which at least one cleaning location is cleaned with pressurized cleaning liquid and/or pressurized ambient air, is proposed, including: a pump-compressor stage for sucking up and conveying the cleaning liquid and/or the ambient air, a fluid path which fluidically connects the pump-compressor stage upstream to a cleaning liquid tank and to an environment of the cleaning device, and a fluid distribution apparatus downstream of the pump-compressor stage, which is fed with the cleaning liquid and/or the ambient air by the pump-compressor stage, the fluid distribution apparatus being fluidically connected to the cleaning location. A vehicle with such a cleaning device, the first and the second use, and a cleaning method for a vehicle are also proposed.

A method and corresponding gas processing system for cleaning deposited solid material from a fouled portion of a gas compressor whilst the gas compressor is in situ in a natural gas processing system are provided. Cleaning of a gas compressor is achieved by accumulating liquid removed from cooling gas used for cooling the gas compressor and supplying the accumulated liquid to an inlet of the gas compressor in order to remove deposited solid material from the gas compressor. The cooling gas is extracted from an intermediate stage of the gas compressor.

An electromagnetic propulsion unit for a land-based wheeled or tracked vehicle is provided. The propulsion unit includes a balancing plate assembly with an outer plate designed to couple to a rotor assembly. In the balancing plate assembly, the outer plate includes a lip that, during rotor assembly rotation, pumps one or more fluids from an air gap formed between the rotor assembly and a stator and the outer plate is constructed out of a non-electrically conductive material.

An electrical submersible pump assembly (ESP) has a centrifugal production pump with production pump stages. A gas separator upstream is from the production pump. A centrifugal charge pump is upstream from the gas separator. The charge pump has charge pump stages and a discharge that leads to an intake of the gas separator. Each of the production pump stages has a higher lifting capacity than each of the charge pump stages. The impellers of the production pump stages have vane exit angles greater than vane exit angles of the impellers of the charge pump stages.

An electric submersible pump assembly with integral heat exchanger, high speed gas separator, high-speed self-aligning bearings, and dual bearing thrust chamber is described. The described gas separator may be used for operating an electric submersible pump at high speeds as well as over a wide range of speeds and flowrates without replacing downhole equipment.

An electric submersible pumping system is constructed with an outer housing which contains an integrated pump and motor. The pump may comprise an impeller disposed within a stator of the motor to form an integrated pump and the motor. An electric submersible pumping system includes a stator having a passage extending longitudinally through the stator. A plurality of stages, including impellers and diffusers, are disposed within the passage.

A system for controlling the geometry of a variable geometry compressor. The system having: a mechanical linkage operable to vary the compressor geometry; a first fluid-powered actuator arranged to operate the linkage and configured to be powered by a pressurised supply of an incompressible fluid; and a second fluid-powered actuator arranged to operate the linkage and configured to be powered by a pressurised supply of a compressible fluid. Wherein the first and second actuators are further arranged to operate in combination on the mechanical linkage such that a first actuator force exerted by the first actuator on the mechanical linkage sums with a second actuator force exerted by the second actuator on the mechanical linkage.
