Slide plate continuous capacity type gas turbine power machinery

Abstract

The invention relates to slide plate continuous capacity type gas turbine power machinery, which comprises a stator, a rotor, a blade, and an end cap. The rotor is eccentrically arranged in the stator. A crescent space is formed between the inner wall of the stator and the surface of the rotor. The blade is installed in the first groove of the rotor. The power machinery is characterized by also comprising a rotary disc, a floating eccentric disc, an elastic coupler, and bearings. Two ends of the central shaft of the rotor are connected to the end cover and the floating eccentric disc through bearings. The floating eccentric disc and a second rotary disc are connected by a bearing. The second rotary disc and a second end cover are connected by a bearing. A first rotary disc and a first endcover are connected by a bearing. The elastic coupler is connected to the second rotary disc through a connection key. The first rotary disc, the second rotary disc, and the stator are coaxial. Two ends of the blade are connected to the first rotary disc and the second rotary disc respectively. The stator is provided with a first air opening and a second air opening. The power machinery can rotateat a high speed and has the advantages of small volume, lightness, high thermal efficiency, large power, and long service life.

Description

technical field [0001] The invention relates to an energy conversion power machine, in particular to a sliding vane continuous volume gas wheel power machine. Background technique [0002] Pneumatic turbine power machinery is widely used in production and daily life. Most of the existing gas turbine power machinery is continuous speed type or discontinuous volume type. [0003] The continuous speed type can achieve small size, light weight and high horsepower due to continuous work. However, its working process requires two energy conversions: potential energy is converted into kinetic energy through the stator and blades; kinetic energy is converted into mechanical work through the blades and rotor. Therefore, the energy loss is large and the thermal efficiency is low. Such as aviation axial flow compressor, airflow compression is that when the airflow passes through the moving blades, the kinetic energy is increased by external work and then passes through Its kinetic ...

AI Technical Summary

Problems solved by technology

[0006] The power machine adopts the continuous volume working mode, which has achieved beneficial effects in overcoming the shortcomings of the continuous speed type and the discontinuous volume type by combining the advantages of both, but there are still the following deficiencies: First, the axial intake and exhaust structure is adopted, The area of ​​the inlet and exhaust ports is too small, which is only suitable for low-power power machinery; secondly, because the rotor is loaded, and the blade is subjected to the difference in airflow pressure between the two elementary chambers, the two sides of the blade and the corresponding sides of the rotor groove are greatly worn. Not only does it affect life, but more importantly, it is not suitable for high-speed rotating power machinery

Third, limited to the experimental conditions, the highest speed is below 3400 rpm, there is no way to increase the speed, the best expansion (or compression) conditions cannot be satisfied, and the airflow expansion (or compression) process is completely out of balance
