Curved saw wheel steamer

Abstract

The invention relates to a curved saw wheel steamer which is provided with a round power wheel, wherein the center of the power wheel is fixedly matched with a wheel shaft, the power wheel is pivoted in the outer casing, and the circumference of the outer casing is provided with a steam inlet port and a steam discharge port, wherein one end of the wheel shaft passes through the center of one side of the outer casing, and a torque is output outwards through the rotation of the end; the middle part of the external part of the power wheel is provided with a plurality of curved concave and convex saw teeth, when the power wheel rotates under the action of steam, the front concave curved surfaces of the curved concave and convex saw teeth apply work under the momentum of the steam, and the back convex curved surfaces of the curved concave and convex saw teeth can reduce the drag produced by steam discharge after work application. The curved saw wheel steamer can still obtain high driving force under the driving of low-pressure steam, and has high power-generating efficiency.

Description

technical field [0001] The invention relates to a steam engine, in particular to an arc saw wheel steam engine. Background technique [0002] With the continuous improvement of industrial life, power consumption is increasing day by day, energy consumption is also increasing, and pollution emissions are also increasing. Pollution control and efficient use of energy are major issues that human beings are currently concerned about. As a clean and convenient secondary energy source, electricity is widely used in various fields of human production and life. The rapid development of the power industry has promoted the continuous updating and progress of power technology. At present, there are various power generation technologies such as thermal power generation, nuclear power generation, diesel power generation, hydropower generation, solar power generation, and wind power generation. Among them, the mainstream power still relies on thermal power. Power generation and other ele...

AI Technical Summary

Problems solved by technology

However, due to the characteristics of high pressure and high temperature of unsaturated steam, the expansion rate of the body of the current steam engine for thermal power generation is very large, and the gap between the blade and the casing is also large, so that the power generation efficiency of the steam engine is low. The energy consumption is large, and due to the fast speed of the impeller, the rotating structure is very worn, etc.

[0004]The impeller of the steam engine commonly used at present is designed so that each blade is obliquely installed outside the impeller, and the steam is punched from the horizontal direction to make the impeller rotate forward. The space is very large, the force of the steam stamping blade is not concentrated, and the efficiency of the force is very low. In addition, because the three sides of the blade are adjacent to the air, and one side is fixed, it is easy to bend the blade when it is impacted by saturated steam, which will reduce the power generation efficiency. ( Because saturated steam has heavy gas quality and uneven momentum)

More importantly, when each blade turns to the position of the steam injection port, the blade is impacted by the steam to generate power. After turning to the position of the steam injection port, the blade will produce resistance to the discharge of the steam. After the steam does work, the discharge streamline will not be smooth. Make the power generation efficiency drop even more

[0005] It can be seen that the above-mentioned existing steam engine obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
