A solar heat receiver includes a casing having an aperture, and a piping system provided in the casing and discharging a heat medium, which is sent from a fluid supply source, to a fluid supply destination after the heat medium is heated by the solar light. The piping system includes: heat receiver tubes that heat the heat medium flowing therein; an inlet header tube that distributes the heat medium, which is introduced from the fluid supply source, to each of the heat receiver tubes, and an outlet header tube that collects the heat medium passing through each of the heat receiver tubes, and leads the heat medium to the fluid supply destination. The inlet header tube and the outlet header tube have a larger inner diameter than each of the heat receiver tubes.

Solar heat receiver and solar heat power generation device

A drive unit of a magnet coupling pump, in which leakage of the magnetic flux to the outside and the effect of the external magnetic field are suppressed. The drive unit includes: a driving magnet () positioned at an outside of the driven magnet () of the magnetic coupling pump () with respect to a rotation axis (A) of the magnetic coupling pump () to face the driven magnet () with a gap; a cup tube portion () made of a ferromagnetic material and in a tubular shape centered on the rotation axis (A); a case main body () including a cup () in which the driving magnet is fixed inside of the cup tube portion; a motor () rotating the cup around the rotation axis, and a tube portion (), which is tubular in shape. The cup is provided in the tube portion () with a gap.

A solar receiver is disposed on a top portion of a tower provided upright on the ground for heating a compressible working fluid by means of heat converted from sunlight collected by heliostats disposed on the ground, to raise the temperature of the compressible working fluid. The solar receiver has modules disposed back-to-back, and each of which includes a casing having a bottom plate to be fixed to the top-portion upper surface of the tower. A heat-transfer-tube unit is accommodated in the casing and includes heat transfer tubes. A sunlight inlet port having a circular shape in front view or an elliptical shape in front view is provided at the center portion of a plate-like member whose lower end is connected to an outer circumferential end of the bottom plate to constitute the casing and that extends obliquely upward from the outer circumferential end.

Solar receiving

The concentrating heat receiver () is provided with a casing () which has an opening portion () into which sunrays are made incident, a heat receiving portion () which is accommodated inside the casing () so that a working fluid flows therethrough and receive heat from sunrays made incident from the opening portion, thereby raising the temperature of the working fluid, and hanging members () in which the upper end sides thereof are coupled to an upper angle () and the other end sides thereof are loosely inserted into through holes () of the casing (), thereby supporting in a hanging manner the heat receiving portion () inside the casing ().

Solar concentrating heat receiver and system thereof

A solar-thermal gas turbine generator is equipped with a compressor, a heat receiver, and a turbine. Additionally, there is a generator that is driven by the solar-thermal gas turbine to generate power; and a steam power generation cycle in which high-temperature air exhausted from the turbine is introduced into a steam generator and in which a steam turbine that is operated with steam generated at the steam generator drives a generator to generator power, wherein a solar-thermal steam generator that generates steam by being heated with heat collected by the light collector is provided upstream of the steam turbine of the steam power generation cycle, and a distribution ratio for distributing the sunlight collected by the light collector to the heat receiver and the solar-thermal steam generator is adjusted in accordance with the sunlight intensity.

Solar-thermal gas turbine generator

Provided are a magnetic coupling as an axial bearing including a driven magnet (B) that is a permanent magnet provided to a rotating body () inside a casing () and a drive magnet (A) that is a permanent magnet placed face to face with the driven magnet in a radial direction of the rotating body outside the casing to be magnetically coupled with the driven magnet, a driving motor () that rotatably drives the drive magnet about an axis (P) of the rotating body, a radial bearing that is a dynamic bearing having annular bearing surfaces (BB) centering on the axis on an inner wall of the casing and the rotating body, each of the annular bearing surfaces being arranged with a gap between the drive magnet and the driven magnet in the radial direction of the rotating body, and a closed impeller (A) including a front shroud (A) arranged on a front side in the axis direction in the rotating body, a rear shroud (A) arranged on a rear side in the axis direction of the front shroud, and a vane (A) arranged between the front shroud and the rear shroud.

Blood pump and pump unit

In a pump conveying a supercritical fluid or a liquid are provided stator slots and motor mold members which are charged between the stator slots, so as to have a stator can of a motor driving the pump from the outside thereof. Additionally, by providing a main shaft of a motor driving the pump and bearings supporting the main shaft with clearance-fitting and by tightening inner rings of the bearings to the main shaft in an axial direction, the bearings are fixed to the main shaft.
