Description

一种新型涡轮a new type of turbine 技术领域Technical field
本发明涉及一种新型涡轮，属于涡轮技术领域。The invention relates to a novel turbine, belonging to the technical field of turbines.
背景技术Background technique
传统的水轮机涡轮结构分为两种，一种是反击式，一种冲击式。反击式是水从叶片之间流走带动水轮旋转；冲击式是水冲击水轮。由于冲击式水轮与外壳下部之间空隙大，水冲到水轮上就落到下部排水口中，导致水等能量物质从涡轮叶片与外壳之间流走，进而造成能量的流失与浪费。The traditional turbine turbine structure is divided into two types, one is a counterattack type, and the other is an impact type. The counterattack type is that the water flows away from the blades to drive the water wheel to rotate; the impact type is the water impact water wheel. Since the gap between the impact water wheel and the lower part of the outer casing is large, the water rushes onto the water wheel and falls into the lower water outlet, causing energy substances such as water to flow away from the turbine blade and the outer casing, thereby causing energy loss and waste.
汽轮机生产都是密排扇叶，生产成本高不易维护，蒸汽从扇叶之间流走，带动汽轮机转子转动，蒸汽从扇叶之间走，导致能量流失。Turbine production is densely fanned, the production cost is high and difficult to maintain, steam flows away from the blades, which drives the turbine rotor to rotate, and steam moves from between the blades, resulting in energy loss.

The cylindrical housing is further provided with an energy inlet and an energy outlet, and the energy inlet and the energy outlet are respectively connected with the grooves of the first end and the end.
所述涡轮单元叶片的末端部是直齿状。The end portion of the turbine unit blade is spur-toothed.
本发明的有益效果：本发明不仅结构简单、安装方便，而且可使得在上一个涡轮单元中散失的能量重新被回收利用，从而提高能源利用率；由于本发明提供的涡轮结构为封闭式结构，因此使得进入涡轮结构的水或蒸汽能够充分推动涡轮叶片旋转，而使能量散失降到最低，从而提高水或蒸汽的做功效率。本发明可应用于水利发电或者蒸汽发电。The invention has the advantages that the invention is not only simple in structure and convenient in installation, but also can re-use the energy lost in the last turbine unit to improve energy utilization; since the turbine structure provided by the invention is a closed structure, This allows water or steam entering the turbine structure to fully propel the turbine blades to rotate, minimizing energy loss, thereby increasing the efficiency of water or steam work.
