Abstract:
A power supply system and method includes a power grid input unit and a diesel generator input unit, separately used for supplying an alternating current to a power supply unit. An automatic transfer switch unit is connected to the power grid input unit and the power supply unit or connected to the diesel generator input unit and the power supply unit, which is used for converting the received alternating current into a direct current. A control unit, which is used for monitoring a current load current and current diesel generator power, determines when to turn off a preset number of power supply loads according to a magnitude relationship between the current diesel generator power and the current load power, as well as according to priority levels of current loads. The power supply system also includes a plurality of loads and at least one storage battery pack.

Abstract:
A lube system is provided and includes an air-oil tank including a deaerator configured to remove a first quantity of oil from a first air-oil supply to generate a second air-oil supply having a second quantity of oil, which is smaller than the first quantity of oil, the air oil tank being configured to output the second air-oil supply to an air vent line, a de-oiler disposed along the air vent line and configured to remove from the second air-oil supply oil mist including oil droplets of a minimum size and a system disposed between the deaerator and the de-oiler, which is configured to encourage formation of the oil droplets of at least the minimum size.
Abstract:
A baffle for engine fluid cooling includes a fluid guide having a pair of side walls, a bottom wall, and a coolant fluid inlet. A channel receives a pair of heat exchangers such that one may be positioned proximate to or above a part of the bottom wall and the other may be positioned proximate to or above another part of the bottom wall. Some coolant entering the guide flows into the first heat exchanger and some coolant is passed under the first heat exchanger and subsequently into the second heat exchanger.
Abstract:
In an internal combustion engine, upper and lower crankcases include a crank chamber, a clutch chamber in communication with the crank chamber, and a cam chain chamber. The upper crankcase includes a second upper partition wall configured to separate the cam chain chamber and the clutch chamber from each other. The lower crankcase includes a first lower partition wall configured to separate the cam chain chamber and the crank chamber from each other, and a second lower partition wall configured to separate the cam chain chamber and the clutch chamber from each other. An oil passage allowing communication between the cam chain chamber and the crank chamber is provided in the first lower partition wall. First passages allowing communication between the cam chain chamber and the clutch chamber are provided respectively in the bottom surface of the second upper partition wall and in the top surface of the second lower partition wall.
Abstract:
The present disclosure provides a hydraulic system of a transmission having a controller and a variable displacement pump. The pump includes an inlet and outlet and is adapted to be driven by a torque-generating mechanism. The system also includes a lube circuit fluidly coupled to the pump. A lube regulator valve is disposed in the lube circuit, such that the lube regulator valve is configured to move between at least a regulated position and an unregulated position. The regulated position corresponds to a regulated pressure in the lube circuit. A pressure switch is fluidly coupled to the lube regulator valve and configured to move between a first position and a second position, where the switch is disposed in electrical communication with the controller. A solenoid is disposed in electrical communication with the controller and is controllably coupled to the pump to alter the displacement of the pump.
Abstract:
A single-cylinder, dual head internal combustion engine wherein in a single, mechanically unconstrained piston moves reciprocally within the cylinder between the two heads. Magnets or nonmagnetized ferromagnetic structures in the piston interact with magnets in a sleeve riding on the outside surface of the cylinder to cause synchronous movement of the sleeve. A yoke coupled to the sleeve may be coupled to a conventional crankshaft to convert the reciprocal movement of the sleeve into rotary motion. Multiple single-cylinder, dual head units may be ganged to form multi-cylinder engine configurations. In one embodiment, the magnets in the sleeve are electromagnets whereby de-energizing the electromagnets decouples the sleeve from the piston, thereby eliminating the need for a mechanical clutch in a power train driven by the engine.
Abstract:
A device for continuously supplying small quantities of grease to a gear or train of gears. The unit consists of an idler gear to which is coupled a screwshaft mounted in a body which is suitably drilled and channeled and to which is connected a spring-loaded grease cartridge. The screwshaft takes grease supplied from the cartridge and conducts a metered amount through the channels to the idler gear where it is expelled between the gear teeth to lubricate gears with which it is in mesh.
Abstract:
A connection device, a control box component, and a fracturing apparatus are provided. The connection device includes: a fixation rack, configured to be fixedly connected with a mounting base; a box connection mechanism, configured to be connected with the control box, and drive the control box to move at least from a first position to a second position relative to the fixation rack. In a case that the control box is located at the first position, the control box is located at a side of the transmission component and a distance between the control box and the transmission component is less than a predetermined distance, and during the control box being moved from the first position to the second position, the control box is away from the transmission component to form an operation space for the transmission component at the first position.
