    摘要: A method for pressure and temperature control of fluid in a series of cryogenic compressors. An actual speed for each compressor and an actual inlet pressure and actual inlet temperature at entry are determined. The maximum speed for each compressor and a desired inlet pressure for the first compressor is provided. A speed index for each compressor is determined from the maximum speed and actual speed of each compressor. A proportional value is determined from the deviation of the actual and desired inlet pressure. A priority value is determined from the smaller of the proportional value and the smallest speed index. A desired inlet temperature for the first compressor and a desired speed for each compressor are determined from the priority value. The actual inlet temperature is adjusted to the determined desired inlet temperature and the actual speed for each compressor is adjusted to the determined desired speed.

    摘要: A fan driving circuit drives a first fan and a second fan which are connected in parallel and connected to an anode of a direct current power. The fan driving circuit includes a pulse width modulation signal generation module, a phase lock and delay module, a first pulse output comparator and a first capacitor. The width modulation signal generation module is connected between an external power and the first fan. The phase lock and delayed module is electrically connected to the pulse width modulation signal generation module. The first capacitor is connected between the DC and the ground. The first fan is supplied as normal by a PWM power supply, the second fan is powered by “shadow” and out-of-phase pulses taken from an inductor in the first fan and stored in the capacitor, to achieve a “two-for-one” power supply aspect, which saves power and reduces operational noise.

    摘要: A method and system improving energy efficiency of a turbojet engine by optimizing rotating speed of a fan and operability of an engine, by freeing the fan from exclusive control of a low-pressure (LP) shaft by providing combined control with a high-pressure (HP) shaft when cruising power has been reached. The turbojet engine include at least one LP turbine and one HP turbine coupled to coaxial LP shafts and HP shafts, respectively, which can drive LP and HP compressors, respectively. The LP compressors include a fan that forms a first primary air-intake compression stage. The LP and HP shafts are mounted on one of two driving mechanisms, an inner ring gear, and a planet carrier for a planetary gear train for driving the fan, the HP shaft being mounted on a disengagement mechanism and the fan being coupled to the planetary gear train via an outer driven ring gear.

    摘要: A cooling system for a generator of a vehicle has an engine, a generator and a wind collection box. The generator has a rotor driven by the engine and a fan synchronously rotating with the rotor. The wind collection box is connected to the generator via a first guiding tube. The fan draws exterior air from the wind collection box and the first guiding tube to allow the exterior air to flow through the generator. Thus, heat in the generator that is mounted in an airtight engine compartment is dissipated.

    摘要: A choke valve (safety valve) is provided in association with a submergible pump employed in oil wells or the like to prevent the flow of well fluid toward the well head when the pump is not operating. Differential pressure across the pump is employed to open the valve, and the valve closes automatically when the pump is de-energized. Bottom-hole pressure merely closes the valve more tightly. A reciprocating tapered valve member controls the opening and closing of a longitudinal passage through a tubular valve housing, the differential pump pressure being applied across an annular piston reciprocating in an annular chamber surrounding the longitudinal passage and connected to the valve member by a plurality of longitudinal piston rods, springs surrounding the piston rods biasing the valve member to a closed position. The storm choke can be operated by fluid pressure applied from the earth's surface in order to permit "killing the well" or flushing sand from the choke.

    摘要: A system for compressing a fluid, such as ethylene monomer and adding a constituent to same to produce a product therefrom, for instance: a polymerized product, such as polyethylene. The system sets forth the use of plural stages of centrifugal compressors requiring a given amount of horsepower for the driving thereof, and only some of the required horsepower is externally supplied. Some of the energy stored in the fluid, through the compressing thereof and the introduction of heat thereto, is deployed in the system to drive some of the compressor stages.
