    • A discharge head for a vertical pump is proposed comprising a base plate (11) for mounting the discharge head, a top plate (12), at least one support member (13) connecting the base plate (11) with the top plate (12), a discharge pipe (15) with an outlet (16) for delivering a fluid, said discharge pipe (15) extending through the base plate (11), and an inner tube (17) for receiving a shaft (4) that connects a drive unit (3) with an impeller (21) of the vertical pump, wherein the inner tube (17) extends in an axial direction (A) and coaxially within the discharge pipe (15) in the region of the base plate (11), passes through a wall of the discharge pipe (15) at an intersection (18), and further extends to the top plate (12), wherein the inner tube (17) comprises a bellows member (19) being located between the intersection (18) and the top plate (12). In addition, a vertical pump with such a discharge head (10) is proposed

    • A combustion staging system for fuel injectors of a multi-stage combustor of a gas turbine engine is provided. The system has pilot and mains fuel manifolds respectively distributing fuel to pilot and mains stages of the injectors. The system further has a splitting unit which controllably splits a metered fuel flow and sends respective portions of the metered flow to the pilot and mains fuel manifolds to perform staging control of the combustor. The splitting unit is able to deselect the mains manifold so that there is no flow into the combustor from the mains manifold. The system further has a cooling flow recirculation line having a delivery section arranged to provide a cooling flow of fuel to the mains manifold when that manifold is deselected so that the deselected mains manifold remains primed with relatively cool fuel. The recirculation line further has a return section arranged to collect the cooling flow from the mains manifold. The system further has one or more fuel pressure sensors which detect the pressure of the cooling flow on the recirculation line. The system further has a control arrangement which is adapted to close off the recirculation line when the pressure sensor(s) indicates a failure of the cooling flow.
    • 提供了用于燃气涡轮发动机的多级燃烧器的燃料喷射器的燃烧分级系统。 该系统具有先导和主燃料歧管,分别将燃料分配给喷油器的引导和主要级。 该系统还具有分裂单元,其可控制地分开计量的燃料流并且将计量流的相应部分发送到引燃和主燃料歧管以执行燃烧器的分级控制。 分裂单元能够取消市电歧管的选择,使得没有流量从市电歧管流入燃烧器。 所述系统还具有冷却流再循环管线,所述冷却流再循环管线具有输送部分,所述输送部分布置成当歧管被取消选择时向所述干线歧管提供冷却燃料流,使得未被选定的干线歧管保持用相对较冷的燃料启动。 再循环管线还具有布置成收集来自干线歧管的冷却流的返回部分。 该系统还具有一个或多个燃料压力传感器,其检测再循环管线上的冷却流的压力。 该系统还具有控制装置,该控制装置适于在压力传感器指示冷却流失败时关闭再循环管线。
