Description
技术领域
本发明涉及用于燃气轮机的第一阶段的转子叶片。
背景技术
燃气轮机涉及旋转热机,其使用来自燃烧的气体将气体的焓转化为有用能量,且其提供机械功率到旋转轴上。
因此,涡轮机通常包括压缩器或者涡轮压缩器,来自外部环境的空气在压力下进入压缩器或者涡轮压缩器内部。
各种喷射器供给燃料,该燃料与空气混合,以形成空气-燃料点火混合物。
涡轮机,实际上,即,涡轮膨胀器携带轴向压缩器,其将机械能供给到使用者,转换在燃烧室中燃烧的气体的焓。
在产生机械能的应用中,膨胀跳跃细分为两个部分跳跃,每一个部分跳跃发生在涡轮机中。高压涡轮机在燃烧室的下游携带压缩器。收集来自高压涡轮机的气体的低压涡轮机然后连接到使用者。
涡轮膨胀器、涡轮压缩器、燃烧室(或者加热器)、出口轴、调节系统和点火系统形成了燃气轮机设备的主要部分。
至于所关心的燃气轮机的功能,已知流体通过一系列入口导管进入压缩器。
在这些导管系统中,气体具有低压和低温的特性,而当其通过压缩器时,气体被压缩,且其温度增加。
气体然后进入燃烧(或者加热)室,其中,其经历进一步较大的温度增加。
气体的温度增加所必须的热量由通过喷射器引入加热室的液态燃料的燃烧提供。
当启动机器时,通过火花塞实现燃烧的触发。
在燃烧室的出口处,高温高压气体通过特殊的导管到达涡轮机,其中,高温高压气体放出在压缩器和加热室(燃烧室)中积累的部分能量,然后通过排放通道流到外部。
由于由气体给予涡轮机的能量大于在压缩器中吸收的,所以一定量的能量保持可用,在机器的轴上,其去除由附件以及移动机械机构的被动阻力吸收的功,形成设备的有用功。
由于高比率能量可用,涡轮机,实际上,即,涡轮膨胀器,通常是多阶段的,以优化由气体转化为有用功的能量转换收益。
因此,阶段为涡轮机的每个部分的构成元素,且包括定子和转子,每个装备有一系列叶片。
然而,所有涡轮机共同的主要必需要求之一为高效率,其必须获得来用于在涡轮机的所有部件上开发。
近年来,技术上超前的涡轮机已经通过升高诸如燃烧温度、压力变化、冷却系统和涡轮机的其它部件的效率之类的热动力学循环参数来进一步改进。
现在,为了进一步提高效率,必须在叶片系统的轮廓的空气动力学参数上开发。
叶片系统的几何构造极大地影响空气动力学效率。
这依赖于这样的事实,即,叶片的几何特性确定相对流体速率的分布,因此影响沿着壁的限制层的分布,以及最后的但不是最小的摩擦损耗。
在低压涡轮机中,观察到,旋转速率工作条件可以从额定速率的50%变化到105%,因此,涡轮机的叶片系统必须将高的空气动力学效率维持在很宽的范围内。
特别是在低压涡轮机的第一阶段的转子叶片的情况下,需要特别高的效率,同时维持合适的空气动力学和机械载荷。
目前,具有允许高效率在涡轮机的工作条件下具有变化,同时能够维持有用的寿命的叶片是困难的。
发明内容
本发明的目的是提供用于燃气轮机的第一阶段的转子叶片,其允许在宽的工作范围内的高空气动力学性能。
还有的目的是提供用于燃气轮机的第一阶段的转子叶片,其同时能够获得部件本身的高的有用寿命。
另一个目的是提供用于燃气轮机的第一阶段的转子叶片,其允许在宽的工作范围内的高空气动力学性能,同时能够获得部件本身的有用寿命。
通过提供如在权利要求1中指定的用于燃气轮机的第一阶段的转子叶片实现了根据本发明的这些目的。
本发明的还有的特性在随后的权利要求中指定。
附图说明
参考包括的示意性附图,从下面的示例性的和非限制性的描述可以更明白根据本发明的用于燃气轮机的第一阶段的转子叶片的特性和优点,其中:
图1是根据本发明的生产有空气动力学轮廓的涡轮机的转子的叶片的凸起视图;

这样,可以维持叶片1的高的有用寿命,也具有高的空气动力学效率,其在燃气轮机的宽的工作范围内为恒定的,或者只有稍微变化。
当使用可变喷嘴时,这有利地证明是特别有用的,喷嘴大大地改变了在第一阶段转子的入口处的气流的流体动力学条件。
根据本发明的还有的方面,转子提供给配备有可变吸嘴的燃气轮机的第一阶段,所述转子包括一系列成形的叶片1,其每个具有成形的空气动力学轮廓。

而且,根据本发明的叶片的空气动力学轮廓由表格I的值通过将闭合曲线20的系列堆叠在一起且连接它们来获得,使得获得连续的空气动力学轮廓。
考虑每个叶片1的尺寸可变性,最好通过熔炼过程获得,每个叶片1的轮廓在垂直于叶片1本身的轮廓的方向上可以具有+/-0.3mm的公差。
每个叶片1的轮廓也可以包括随后涂覆的涂层,使得改变轮廓本身。
优选地,所述抗磨损的涂层具有在垂直于每个叶片表面方向上限定的厚度,其范围从0到0.5mm。
而且,很明显,表格I的坐标的值可以乘以或者除以校正常数,以获得更大或者更小比例的轮廓,同时维持相同的形式。
因此,可以看出,用于根据本发明的燃气轮机的第一阶段的转子叶片实现了上述的目的。
