Supercritical fluid power device

Abstract

The invention belongs to the technical field of energy power, and discloses a supercritical fluid power device. The supercritical fluid power device comprises a turbine chamber, a Tesla turbine, an input part annularly arranged outside the Tesla turbine in the circumferential direction, and two bearing assemblies symmetrically arranged on the two sides of a disc of the Tesla turbine. Each bearingassembly comprises a plurality of first bearing sheets sleeving a shaft and a plurality of second bearing sheets, wherein a gap is formed between one of the two first bearing sheets on the outermost side and the input part, and a gap is formed between the other one of the two first bearing sheets on the outermost side and the turbine chamber; the second bearing sheets correspondingly sleeve the outer sides of the middle first bearing sheets, balls are arranged between the two sides of each second bearing sheet and the first bearing sheet adjacent to the second bearing sheet, the balls abut against the second bearing sheets, gaps are formed between the balls and the first bearing sheets, and gaps are formed between the second bearing sheets and the first bearing sheets. According to the supercritical fluid power device, the bearing abrasion probability is close to zero, and the service life of the whole device is prolonged.

Description

technical field [0001] The invention relates to the technical field of energy and power, in particular to a supercritical fluid power device. Background technique [0002] Tesla turbine, also known as bladeless turbine, is shaped like a shaft with multiple smooth and thin disks fixed at a certain distance. When the air flow hits these disks from the tangential direction, the air flow will Adsorbed on the disc due to the viscosity of the surface layer. When the speed of the airflow slows down and energy is applied to the disc at the same time, the gas will spiral and move towards the heart and be discharged, thereby driving the overall operation. [0003] At present, in the device with the above-mentioned Tesla turbine, it will be used with a bearing. However, due to the low torque of the Tesla turbine and the friction that exists when the inner and outer rings of the bearing itself rotate, the device with the above-mentioned Tesla turbine will be on the bearing. The large ...

Problems solved by technology

[0003] At present, in the device with the above-mentioned Tesla turbine, it will be used with a bearing. However, due to the low torque of the Tesla turbine and the friction that exists when the inner and outer rings of the bearing itself rotate, the device with the above-mentioned Tesla turbine will be on the bearing. Higher power loss also results in higher wear and shorter service life of the existing bearings and thus shorter service life of the device with the aforementioned Tesla turbine
