A liquid pressurizing apparatus, comprises a tank provided on a device installation surface for storing liquid so that a fluid level is located above the device installation surface; and a vertical pump including a suction port connected to the tank, multi-stage impellers arranged in a vertical direction, and a discharge port for discharging the liquid passing through the multi-stage impellers. The multi-stage impellers include a first stage impeller positioned at the lowest part of the multi-stage impellers and being configured such that the liquid from the suction port flows into the first stage impeller. The first stage impeller is disposed below the device installation surface.

Liquid pressurizing apparatus and urea synthesis plant

A vertical pump includes: a rotary shaft; multi-stage impellers; a casing accommodating the multi-stage impellers; a mechanical seal provided in a penetration part of the casing for the rotary shaft; a balance sleeve, the balance sleeve being positioned between a final stage impeller of the multi-stage impellers and the mechanical seal in the penetration part for the rotary shaft; an intermediate chamber provided between the rotary shaft and the casing and provided on an opposite side of the multi-stage impellers across the balance sleeve in an axial direction of the rotary shaft, the intermediate chamber communicating with an intermediate stage impeller among the multi-stage impellers; a low pressure chamber provided between the rotary shaft and the casing, the low pressure chamber communicating with a low pressure side compared to the intermediate chamber; and a partition wall part dividing the intermediate chamber and the low pressure chamber.

Vertical pump and urea synthesis plant

A rotary machine has a housing that houses a fluid in a supercritical state, a rotary shaft that penetrates the housing, rotation rings that rotate integrally with the rotary shaft, and stationary rings that contact the rotation rings when the rotary shaft is stopped, the stationary rings being positioned in a state in which sealing gaps are defined between the rotation rings and the stationary rings when the rotary shaft rotates, a circulating pipe path that supplies a portion of the fluid to inlet portions of the sealing gaps, a temperature-adjusting device that adjusts a temperature of the fluid in the circulating pipe path, and a control unit that controls operation of the temperature-adjusting device so as to heat the inlet portions of the sealing gaps to a predetermined temperature before the rotary shaft is driven.

Rotary machine

A motor vehicle to which a control device is applied includes an idling stop control section for stopping operation of an engine when a predetermined stopping condition is fulfilled while the engine is idling, and a neutral-at-idle control section for shifting a transmission of the vehicle into neutral when a predetermined shift-into-neutral condition is fulfilled. While a post-stoppage elapsed time measured by a timer is shorter than or equal to a predetermined time after the vehicle stops moving, operation of the engine is stopped by the idling stop control section if the predetermined stopping condition is fulfilled but shifting of the transmission into neutral by the neutral-at-idle control section is prohibited even if the shift-into-neutral condition is fulfilled.

Control device for motor vehicle

An output control device configured to control the output of a running drive source mounted on a vehicle includes an anomaly discriminator which judges that the output control device is anomalous, if excess acceleration G (output difference index) of the vehicle remains greater than or equal to a predetermined threshold value G. . . , Gfor a predetermined time t, . . . , tor longer, wherein the predetermined time t, . . . , tfor the anomaly discrimination is set so as to shorten with increase in the threshold value GGof the excess acceleration of the vehicle.

Output control device for vehicle

The control device, which is driven by an engine mounted on the vehicle, generates electric power and determines a power generation voltage for supplying the electric power to an electrical load and an electricity storage unit, comprising an electricity storage amount detection unit for detecting an amount of electricity stored in the electricity storage unit, by integrating an input/output current to/from the electricity storage unit a voltage lowering unit for lowering the power generation voltage when a predetermined electricity storage amount is detected by the electricity storage amount detection unit, a time measuring unit for measuring time elapsed after termination of charging/discharging of the electricity storage unit, and a lowering prohibition unit for prohibiting the power generation voltage from being lowered by the voltage lowering unit if the time elapsed after termination of the charging/discharging is longer than or equal to a predetermined time.

Charging control unit of electric power generation control device for motor vehicle

An electric power generation control device for a motor vehicle is provided which ensures a satisfactory regenerative effect without entailing flickering of or reduction in life of headlights even if the headlights are turned on at all times. The electric power generation control device lowers the power generation voltage of an alternator when the electricity storage amount of a battery is at or above a predetermined level. While lighting of a headlight bulb is detected, lowering of the power generation voltage is restrained if the state of sunlight is equivalent to nighttime, and the power generation voltage is allowed to be lowered if the sunlight state is equivalent to daytime.

Electric power generation control device for motor vehicle

An engine start controller having a starter motor that is driven by battery to start engine, an activation switch that sends to the starter motor a START command for starting the engine, an activation circuit that connects the starter motor to the battery to supply a drive current, and an engine start control unit that issues an OPERATE command for operating the activation circuit when receiving the START command from the activation switch, and supplies the drive current to the starter motor. The controller is provided with a bypass circuit that directly sends to the activation circuit the START command that has been sent from the activation switch.
