An oil blending system for a marine diesel two-stroke engine and/or generator comprises a blender having at least one inlet for receiving a lubrication oil and at least one other component and at least one outlet for outputting a mixed lubrication oil composition to the engine or generator. A blender controller is configured to receive parameter data on the current lubrication oil status used in the engine or generator and receive parameter data on the current engine and/or generator status. The blender controller is also configured to automatically determine whether the currently used lubrication oil is within a predetermined parameter range based on the current engine and/or generator status. If the current lubrication oil is outside a predetermined parameter threshold, the blender controller is configured to determine a new lubrication oil composition for the engine or generator.

A hydraulic fracturing plan executable by a hydraulic fracturing system to hydraulically fracture a plurality of oil and gas wells.

A planetary reduction gear (10) for an aircraft turbine engine, said reduction gear comprising a rotatable sun gear, a rotatable ring gear (9) and satellite gears meshed with the sun gear and the ring gear and carried by a planet carrier intended to be fixed to a stator, the reduction gear further comprising an annular trough for recovering and channelling lubrication oil that is mounted around the ring gear, characterised in that the reduction gear further comprises an annular deflector (22) fixed to the ring gear and configured to route the oil exiting radially towards the outside of the ring gear up to the trough by virtue of centrifugal forces, the trough comprising an annular chamber (18) which is axially remote relative to a median plane (P) substantially passing through the centre of the ring gear, and an annular duct (20) located on a side of said chamber and emerging in said chamber.

Magnetic chip detectors and associated for detecting metallic chips in engine fluid of an engine are provided. A magnetic chip detector includes first and second magnetic chip capture zones. The first magnetic chip capture zone includes a first electrically conductive terminal spaced apart from a second electrically conductive terminal to define a first chip-receiving gap therebetween. The second magnetic chip capture zone includes a third electrically conductive terminal and either the second electrically conductive terminal or a fourth electrically conductive terminal to define a second chip-receiving gap therebetween. The magnetic chip detector includes an electric circuit including both the first chip-receiving gap and the second chip-receiving gap. The electric circuit provides an output indicative of a chip detection by one or both of the first magnetic chip capture zone and the second magnetic capture zone.

A filter for filtering particulates from a fluid stream includes a filter element with a filter medium and a metallic debris sensor assembly. The metallic debris sensor assembly includes a core and a coil of electrically-conductive wire. The core has a first end, a second end, and an intermediate portion interposed between the first and second ends. The first end is disposed in spaced relationship with the second end such that a measurement area is disposed therebetween. The coil of electrically-conductive wire is wound around the intermediate portion of the core. The core is adapted to generate a magnetic field in the measurement area when an electrical current is passed through the coil. At least a portion of the filter medium of the filter element is disposed within the measurement area. The filter can be incorporated into a wear detection system and used in methods of monitoring.

A cleaning system of a vehicle oil circuit is provided, including a filter unit, an oil storage unit and a flushing unit. The filter unit includes a filter chamber, a first oil inlet tube and an oil outlet tube. The first oil inlet tube is communicated with a first opening of the vehicle oil circuit. The oil outlet tube is communicated with a second opening of the vehicle oil circuit. The oil storage unit includes a waste oil chamber and a second oil inlet tube communicated with a third opening of the vehicle oil circuit. The flushing unit includes a flushing chamber and a flushing tube. The flushing chamber receives a washing oil. The flushing tube is communicated respectively with the flushing chamber and a fourth opening of the vehicle oil circuit. The flushing tube guides the washing oil to enter the vehicle oil circuit.

A cleaning system for a vehicle oil circuit is provided, including a heat exchange unit. The heat exchange unit includes an oil inlet channel, a first container, a second container and an oil outlet channel. The first container is located within the second container. The first container defines a first space communicated with the oil inlet channel and the oil outlet channel, and the first container and the second container define a second space therebetween and non-communicated with the first space. The oil inlet channel guides an oil from the vehicle oil circuit to the first space, and the oil outlet channel discharges the oil from the first space. The first space receives the oil, and the second space receives a detergent. When the oil is in the first space, a heat of the oil is transferred to the detergent through the first container.

A fluid storage and dispensing system that safely and efficiently stores all grades of motor oil is provided. The system is configured to accurately dispense motor oil into vehicles. The system may also be used for the storage of and dispensing of other fluids.

A hydraulic fracturing plan executable by a hydraulic fracturing system to hydraulically fracture a plurality of oil and gas wells.

An industrial oil degassing system and method to remove gas from an industrial machine oil. Described is an industrial oil degassing system, including a pressure tank under pressure to receive oil charged with gas, a separation tank with an atmospheric pressure to separate gas from the oil, and a seal oil tank with an atmospheric pressure to receive the degassed oil from the separation tank. Further described is a method for industrial degassing of oil with the steps of exerting a pressure to a pressure tank, supplying the oil to the pressure tank, supplying the oil from the pressure tank to a separation tank with atmospheric pressure, separating gas from the oil in the separation tank, and supplying the degassed oil to a seal oil tank with atmospheric pressure.
