多发动机设备
技术领域
本发明涉及多发动机设备。
背景技术
图1示出了从现有技术已知的多发动机设备1的细节，例如被用于船舶上或用在海事应用中。因而，图1中示出的多发动机设备1包括多个发动机2、3和4，它们可以被实施为燃气发动机或双燃料发动机。此外，图1示出多发动机设备1的燃料供给系统5，通过该燃料供给系统5发动机2、3和4可被供给气体燃料和进气空气的混合物。
从现有技术已知的多发动机设备1的燃料供给系统5对于气体燃料包括燃料管线6、7、8以及分配给燃料管线6、7、8的气体压力调节阀9、通风阀10和切断阀11。经由燃料供给系统5的燃料管线6、7、8，取决于气体压力调节阀9、通风阀10和切断阀11的开关位置，可以沿多发动机设备1的发动机2、3和4的方向输送气体燃料，其中多发动机设备1的每个发动机2、3和4被分配一个混合物形成单元12，通过混合物形成单元，气体燃料可以在多发动机设备1的各自发动机2、3和4的气缸13的上游与进气空气混合，以便以这种方式向发动机2至4的气缸13提供燃气和进气空气的混合物用于燃烧。为了简洁起见，在图1中对于多发动机设备1的每个发动机2、3和4仅示出一个气缸13。
在从现有技术已知的根据图1的多发动机设备1中，燃料供给系统5包括对于每个发动机2、3和4的独立的气体压力调节阀9、独立的通风阀10以及独立的切断阀11，它们被接收在对于每个发动机2、3和4的独立壳体14中。燃料管线6、7和8是双壁管，其中内管6a、7a和8a在各自发动机2、3和4的各自混合物形成单元12的方向上引导各自气体燃料，并且其中外管6b、7b和8b围绕各自的内管6a、7a和8a并在各自壳体14的方向上排出任何可能的气体泄漏。
从现有技术已知的多发动机设备具有相对复杂的构造。需要简化多发动机设备的构造。尤其需要通过简化燃料供给系统的构造来减小多发动机设备的燃料供给系统的组件所需的安装空间。
发明内容
由此着手，本发明基于创造一种新型多发动机设备的目的。此目的通过根据权利要求1的多发动机设备解决。根据本发明，燃料供给系统的所有切断阀和所有通风阀定位在共同的壳体中。
由于多发动机设备的燃料供给系统的所有切断阀和所有通风阀都定位在共同的壳体中的事实，在一方面简化多发动机设备的构造，同时尤其减小多发动机设备的燃料供给系统的各部件的安装空间要求。
根据本发明的进一步改进，定位在共同壳体中的共同的切断阀和共同的通风阀对于所有发动机存在。替代地，独立的切断阀和独立的通风阀对于所有发动机存在，它们定位在共同壳体中。尤其当对于多发动机设备的所有发动机而言存在定位在共同壳体中的共同的切断阀和共同的通风阀时，能够特别大地简化了多发动机设备的构造，并且特别大地减小了特别是燃料供给系统的部件的安装空间要求。
根据本发明的进一步改进，多发动机设备的燃料供给系统包括对于每个发动机的独立的气体压力调节阀，其优选地在单独壳体中定位在切断阀和通风阀的下游。通过这样，能够进一步简化多发动机设备的构造，并且进一步减小特别是燃料供给系统的安装空间要求。
对于引导到各自发动机的各自燃料管线各自的气体压力调节阀到各自发动机的发动机船坞连接的距离优选地是气体压力调节阀的标称宽度的5倍到100倍之间，更优选地在5倍到75倍之间，特别优选地在5倍到50倍之间，最优选地在5倍到20倍之间。这样的从各自发动机的各自发动机船坞连接到各自气体压力调节阀的距离是优选的，以便在一方面提供气体压力调节阀下游的各自燃料管线的足够大的调节距离，并且在另一方面通过减小气体压力调节阀下游的各自燃料管线的缓冲部分使气体压力调节的动态最小化。
附图说明
本发明的优选的进一步改进从从属权利要求和下面的描述中获得。通过附图更详细地解释本发明的示例实施例，而没有限制于此。附图示出了：
图1是根据现有技术的多发动机设备的细节；
图2是根据本发明的第一多发动机设备的细节；和
图3是根据本发明的第二多发动机设备的细节。
具体实施方式
本发明涉及多发动机设备，尤其是用于船舶或海事应用。
图1和2分别示出根据本发明的多发动机设备21的示例实施例，在所示的示例实施例中每个多发动机设备21包括设计为燃气发动机或双燃料发动机的三个发动机22、23、24。本质上发动机的数量是完全示例性的。发动机的数量也可以等于二个、三个或多于三个。
多发动机设备21包括燃料供给系统25，通过该燃料供给系统发动机22、23、24可以被供给以气体燃料和进气空气的混合物，其中燃料供给系统25包括用于气体燃料的燃料管线26、27和28，如同通常在实践中，所述燃料管线以双壁的方式包括内管26a、27a、28a和围绕各自内管26a、27a、28a的外管26b、27b、28b，以便在发动机22、23、24的方向上通过各自内管26a、27a、28a引导燃料。形成在各自内管26a、27a、28a和各自外管26b、27b、28b之间的各自燃料管线26、27、28的中空空间用作限定的泄露排放。
根据图2和3的多发动机设备21的各自燃料供给系统25还包括气体压力调节器29、通风阀30以及切断阀31。通风阀30用作使各自燃料管线26、27、28的内管26a、27a、28a通风。在图2和3的多发动机设备21的燃料供给系统25的情况下，燃料供给系统25的所有切断阀31和所有通风阀30定位在共同的、特别是气密的壳体34中。由于这个原因，一方面能够简化燃料供给系统25的构造，另一方面减小燃料供给系统的安装空间要求。
虽然在图2的示例性实施例中燃料供给系统25包括位于共同壳体34中的用于多发动机设备21的每个发动机22、23、24的独立的切断阀31以及独立的通风阀30，图3的多发动机设备21的燃料供给系统25包括对于所有发动机22、23和24共同的切断阀31以及共同的通风阀30，它们定位在共同壳体34中。
在图2的示例实施例中，共同供给管线36因此通向共同的壳体34，在该共同的壳体中布置发动机32、33、34的独立的切断阀31和独立的通风阀30。在发动机22、23和24的方向上引导来自定位在壳体34中的阀30、31的气体燃料的燃料管线26、27、28起从共同壳体34的独立排放管线的作用。在图3的示例实施例中，多发动机设备21的燃料供给系统25同样包括这样的共同供给管线36。然而引导到各自发动机22、23、24的独立燃料管线26、27、28在独立的切断阀31和通风阀30的上游的壳体34的区域中还没有分叉，但只在壳体34的下游或共同的切断阀31和通风阀30的下游分叉。
图2和3的各自多发动机设备21，亦即，各自多发动机设备21的各自燃料供给系统25包括对于各自发动机22、23、24的独立的气体压力调节阀29，其定位在切断阀31的下游和通风阀30的下游、以及用于切断阀31和通风阀30的共同壳体34的下游，亦即，每个气体压力调节阀29在用于它的单独的、特别是气密的壳体35中。
与从现有技术已知的多发动机设备31对比，气体压力调节阀29没有以到发动机的明显距离定位在切断阀以及通风阀的上游，而是以到发动机22、23、24相对短的距离定位在通风阀30以及切断阀31的下游，其中，为了提供各自燃料管线26、27和28的分别在各自气体压力调节阀29下游的限定的调节距离，并且为了减少各自燃料管线26、27和28的分别在各自气体压力调节阀29上游的缓冲部分、因此优化气体压力调节的动态，设计对于引导到各自发动机的各自燃料管线26、27、28的各自气体压力调节阀29到各自发动机22、23、24的所谓发动机船坞连接（engine dockyard connection）的距离。
对于分别引导到各自发动机的各自燃料管线26、27和28的各自气体压力调节阀29到各自发动机22、23、24的发动机船坞连接的距离在这个例子中优选地等于各自的气体压力调节阀29的标称宽度的5倍至100倍之间，更优选地在5倍至75倍之间，特别优选地在5倍至50倍之间，最优选地在5倍至20倍之间。
由气体压力调节阀29的壳体35限定的内部空间和由切断阀31和通风阀30的共同壳体34限定的内部空间通过形成在各自的内管26a、27a、28a和各自的外管26b、27b、28b之间的燃料管线26、27、28的中空空间相联接，以便引导可沿切断阀31和通风阀30的共同壳体34的方向发生的任何气体燃料的泄露，并且通过共同壳体34以限定的方式排放所述泄露。在图2和3中，从这个意义上说，虚线箭头示出了多发动机设备21的燃料供给系统25的通风37。除了该通风37，壳体34优选是气密的。该通风37的进口优选地形成在发动机22、23、24的区域中、在共同壳体34的区域中和在燃料管线26、27、28的区域中。该通风37的出口优选地形成在壳体34的区域中。
在气体压力调节阀29的下游，气体燃料是通过燃料管线26、27、28的内管26a、27a、28a可被供给到各自发动机22、23、24的混合物形成设备32，以便在各自的混合物形成单元32的区域中提供气体燃料和进气空气的混合物并向各自发动机22、23、24的气缸33提供该混合物。
因此，在根据本发明的具有多个发动机的多发动机设备中，对于气体燃料的燃料供给系统的所有切断阀和通风阀被定位在共同壳体中。气体压力调节阀在用于切断阀和通风阀的此壳体的下游、以距发动机一个短距离被布置在分别的壳体中。通过本发明，能够简化多发动机设备的构造。能够节省安装空间和成本。能够改进气体压力调节的动态。
