Problems solved by technology

[0002] General generators need coal to provide energy for power generation, but this will pollute the environment, and coal is a non-renewable resource that will eventually be used up. Therefore, generators that provide energy through non-polluting and renewable energy are the future generators. Mainstream, but existing geothermal generators have low efficiency and complex structures

Abstract

The invention discloses a high-speed direct-drive terrestrial heat generating system. A driving part directly drives a high-speed motor part via a thin-walled sleeve coupling; vibration of the driving part is absorbed via the transformation of an oil film damper mounted outside a supporting bearing, and the rigidity of a supporting part can be changed, as a result, the driving part can bear high rotation speed running so as to achieve high-speed generating; the driving part bears a higher rotation speed and does not need to be raised in speed via a gear shifting box, and the driving part is directly connected with a motor via the thin-walled sleeve coupling, so as to achieve direct driving, simplify the structure of a generating system and reduce the size of the generating system; a molybdenum and a graphite ring are paired and play a role of a thrust bearing, and the coning motion of a turbine disc can be restrained, and the stability of a rotor is kept; and the generating system is simple in structure, an air bearing is adopted to support the high-speed motor part, lubrication and cooling are not required, and meanwhile, the casing hood of the high-speed motor part is integral, and the structure is simple.

Description

technical field [0001] The invention belongs to the field of geothermal power generation, in particular to a high-speed direct-drive geothermal power generation system. technical background [0002] General generators need coal to provide energy for power generation, but this will pollute the environment, and coal is a non-renewable resource that will eventually be used up. Therefore, generators that provide energy through non-polluting and renewable energy are the future generators. Mainstream, but existing geothermal generators have low efficiency and complex structures. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a high-speed direct-drive geothermal power generation system, which has high integration, high efficiency, high-speed direct drive does not need a gearbox, can continuously generate electric energy, and has no environmental hazards specialty.
