Low-pressure steam turbine

Abstract

A low-pressure steam turbine comprises a frame and a rotatable spindle. The spindle is arranged on the frame and provided with a rotor, cavities are uniformly distributed circumferentially, an air bag is mounted inside each cavity and provided with an air inlet passage and an air outlet passage, an electromagnetic reversing valve is arranged between the air inlet passage and the air outlet passage and located on a connecting shaft, one end of the spindle is connected with a power generator to realize power generation, and the other end of the spindle is provided with a rotary air supply valve which is further connected with an air source. The low-pressure steam turbine which is designed on the basis of fluid mechanics breaks the scope of all power machines, is a perfect combination of the fluid mechanics, the air pressure mechanics, the lever mechanics and the potential energy mechanics, and is capable of circulating the self energy source and realizing multiple work application, so that mechanical efficiency of the steam turbine is improved greatly and more energy can be saved. Besides, heat insulation and dissipation are out of consideration since ultrahigh pressure steam driving is omitted. Accordingly, the low-pressure steam turbine is simple in structure, low in cost, convenient in maintenance and durable, and can be applied to power dragging and power generation widely.

Description

technical field [0001] The invention relates to a power machine, specifically, a low-pressure steam turbine designed based on fluid mechanics. Background technique [0002] The traditional high-pressure steam turbine is still an indispensable power machine in today's society. Water is heated in a special boiler and turned into ultra-high pressure steam to blow the impeller of the steam turbine and output power. Because the density of the gas is very small, it disperses immediately after blowing on the impeller of the steam turbine, so the power obtained is greatly reduced. If you want to increase the power output, you can only increase the pressure of the steam. In order to save energy and reduce emissions, increase the firepower The efficiency of power generation requires the installation of supercritical thermal power units. The steam pressure is astonishingly high at 25 MPa. The technical requirements are very high in all aspects. my country is currently developing a 1000...

AI Technical Summary

Problems solved by technology

The power unit is designed in the shape of a blade, with high air resistance and low power conversion efficiency; the structure of the rotary air supply valve is very complicated, which requires high processing technology; the reversing valve directly contacts the ring cam to control the switch state, and the reversing valve is very easy to damage; The airbag has two interfaces, the air inlet and the air outlet, which increases the difficulty of installation and sealing; the circulation of the device from large to small, each of which operates independently, each must have an independent rack, independent Generator, independent rotary air supply valve and air supply pipeline greatly lengthen the circulation path of compressed air, greatly increase the cost, and take time and effort to manufacture and install
