具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例公开的燃气轮机启动系统进行详细地说明。
如图1至图3所示，本申请实施例公开一种燃气轮机启动系统，所公开的燃气轮机启动系统包括发动机、液压启动系统200、燃气轮机300和负载模块400。
其中，在发动机、液压启动系统200、燃气轮机300与负载模块400均设置于同一底盘100上的情况下，底盘100能够作为发动机、液压启动系统200、燃气轮机300与负载模块400的安装基础，同时底盘100能够对液压启动系统200、燃气轮机300与负载模块400实现运输，从而使得本申请中的燃气轮机启动系统能够成为移动式的燃气轮机启动系统，即能够在不同的地方为不同的临时大功率动力输出场景提供动力。
也就是说，在本申请中，由于底盘100能够对发动机、液压启动系统200、燃气轮机300以及负载模块400实现运输，从而使得本申请中的燃气轮机启动系统能够实现移动，从而能够缓解建造固定的燃气轮机启动系统而导致燃 气轮机启动系统的经济性和通用性较差的问题。同时，燃气轮机300本身的功率较大，从而能够带动大功率的负载模块400实现大功率的临时启动应用。本申请中的负载模块400可以是柱塞泵、发电机等可与燃气轮机300传动相连的设备中的至少一者。本申请不对负载模块400的具体种类进行限制。
本申请实施例公开的燃气轮机启动系统通过对相关技术中的燃气轮机启动系统的结构进行改进，通过将发动机、液压启动系统200、燃气轮机300以及负载模块400均设置于同一底盘100上，从而使得底盘100能够对发动机、液压启动系统200、燃气轮机300和负载模块400实现运输，即使得本申请的燃气轮机启动系统为可移动的燃气轮机启动系统，能够满足对不同地方的临时大功率动力输出的需求，也就是说，本申请实施例公开的燃气轮机启动系统能够解决背景技术中所述的固定的燃气轮机启动系统的经济性和通用性较差的问题。
在本申请可选的技术方案中，燃气轮机启动系统可以包括底盘车，底盘车包括底盘100和发动机，发动机与液压启动系统200相连，以使发动机中的第一动力能够传输至液压启动系统200，液压启动系统200与燃气轮机300相连，以使液压启动系统200的第二动力能够传输至燃气轮机300，燃气轮机300与负载模块400相连，从而使得燃气轮机300的第三动力能够传输至负载模块400。在此种情况下，底盘车本身具有的发动机能够作为整个燃气轮机启动系统的动力源，从而能够避免额外需要对燃气轮机启动系统配置动力源，进而能够减小整个燃气轮机启动系统的重量与成本，同时，有利于燃气轮机启动系统实现道路运输。当然，在此种情况下，底盘车的发动机的一部分动力供底盘车自身行走，另一部分动力可以作为第一动力。
本申请实施例公开的燃气轮机启动系统还可以包括取力器500，取力器500分别与发动机和液压启动系统200相连。在此种情况下，取力器500有利于将发动机的第一动力取出并输入至液压启动系统200中，用以使得液压启动系统200实现运行。并且，在燃气轮机启动系统的实际运用中，工作人 员可根据液压启动系统200需要的动力大小对取力器500的具体安装位置进行选择，从而使得取力器500能够实现对发动机不同功率的取用，本申请不对取力器500在底盘100上的具体安装位置进行限定。当然，取力器500的规格种类多样，不同规格的取力器500能够从发动机中取得的功率大小不同，本申请不对取力器500的具体规格进行限制。
在本申请实施例公开的燃气轮机启动系统中，液压启动系统200可以包括油箱210、液压泵220和液压马达230，液压泵220的进口与油箱210连通，液压泵220的出口与液压马达230的进油管路连通，液压马达230的回油管路与油箱210连通，液压马达230与燃气轮机300相连，以使液压马达230的第二动力传输至燃气轮机300，发动机与液压泵220相连。从而使得发动机能够将第一动力传输至液压泵220中，进而带动液压马达230实现运转。
具体的，发动机在启动后，发动机可将自身的第一动力传输至液压泵220，即发动机带动液压泵220运行，液压泵220可将油箱210中的油液从液压泵220的进口送入液压泵220中，液压泵220能够将具有压力的油液通过液压泵220的出口排至液压马达230中，从而驱动液压马达230实现运转，进而使得液压马达230能够带动燃气轮机300实现运转。
在本申请公开的燃气轮机启动系统中，燃气轮机300在不同的启动阶段的转速要求不同，为满足燃气轮机300不同的转速需求，在进一步的技术方案中，液压启动系统200还可以包括调速阀240，调速阀240设置于液压泵220与液压马达230之间，且分别与两者导通。
在上述情况下，液压泵220能够将具有压力的油液通过液压泵220的出口排至调速阀240中，通过对调速阀240的阀门的开度进行调节，从而能够调节进入至液压马达230中的油量，进入液压马达230中的油量不同，使得液压马达230的转速不同，而不同转速的液压马达230可以通过离合器或减速器与燃气轮机300相连，用于使得燃气轮机300实现不同的转速，进而能够满足燃气轮机300启动时在不同阶段的不同转速需求。即调速阀240能够 对通过的油量实现调节，从而能够满足燃气轮机300启动时在不同的阶段对转速的不同需求。
由于液压马达230在不同转速的时候，进入液压马达230中的油液的多少不同，也就是说，此时，从液压泵220的出口进入到调速阀240，继而进入到液压马达230中的油量是变化的。具体的，在液压马达230的转速较小的时候，调速阀240的开度较小，从而使得需要从液压泵220的出口排至调速阀240中的油量较小，此时，液压泵220为定量泵的情况下，液压泵220的出口排出的油量可能大于调速阀240允许通过的油量，从而导致液压泵220的出口处可能发生油液溢出的情况，为避免发生油液从液压泵220的出口溢出的情况，在进一步的技术方案中，液压启动系统200还可以包括第一旁通阀250，第一旁通阀250的进口与液压泵220的出口连通，第一旁通阀250的出口与油箱210连通。第一旁通阀250具体可以为溢流阀，例如压力溢流阀、流量溢流阀等，本申请实施例不对第一旁通阀250的具体种类进行限定。当然，还可以为普通的开关阀。
在上述情况下，当进入调速阀240中的油量小于定量泵的出口排出的油量的情况下，定量泵的出口排出的多余的油量能够通过第一旁通阀250回到油箱210中，从而能够避免液压泵220的出口发生油液溢出的情况。
在另一种可选的技术方案中，液压泵220可以为变量泵。在此种情况下，在调速阀240中允许通过的油量发生变化的情况下，变量泵通过出口排出的油量能够适应性的发生变化，用以适应调速阀240对液压马达230的转速的调节，此时，液压泵220的出口处无需设置第一旁通阀250，有利于简化液压启动系统200的整体设置。
在本申请实施例公开的燃气轮机启动系统中，液压启动系统200还可以包括过滤器，油箱210与液压泵220的进口之间设有过滤器，和/或，液压马达230的回油管路与油箱210之间设有过滤器。可选的，过滤器可以包括第一过滤器260，第一过滤器260设于油箱210与液压泵220的进口之间，且 与两者导通。在此种情况下，从油箱210流入至液压泵220的油液经过第一过滤器260，从而使得第一过滤器260能够将油液的杂质和颗粒物进行过滤，有利于液压泵220和液压马达230等构件的良好运行，即能够缓解油液中的杂质和颗粒物对液压泵220和液压马达230等构件产生磨损的问题，进而有利于整个液压启动系统200的良好运转。
在本申请实施例公开的燃气轮机启动系统中，可选的，过滤器还可以包括第二过滤器270，第二过滤器270设置在液压马达230的回油管路与油箱210之间，且与两者导通。在此种情况下，从液压马达230的回油管路回流至油箱210中的油液经过第二过滤器270，从而使得第二过滤器270能够将回油管路的油液中的杂质和颗粒物实现过滤，从而能够减少回流至油箱210的油液中的杂质和颗粒物，进而有利于减少油箱210中的油液在整个液压启动系统200中实现循环的过程中，而对液压启动系统200中的元件和管道产生磨损的问题。
本申请的液压启动系统200可以同时包括第一过滤器260与第二过滤器270，也可以只包括其中的一者，具体可由工作人员根据油液的质量以及使用需求进行选择性安装，本申请对过滤器的数量和安装位置不进行具体限制。
在油液中的杂质和颗粒物较多或是第二过滤器270使用时间较长的情况下，第二过滤器270可能被杂质和颗粒物堵塞，此时，液压马达230的回油管路中的油液无法通过第二过滤器270回流至油箱210中，这导致整个液压启动系统200不能继续运转。
为避免上述情况发生，在进一步的技术方案中，液压启动系统200还可以包括第二旁通阀280，第二旁通阀280的进口与液压马达230的回油管路连通，第二旁通阀280的出口与油箱210连通。在此种情况下，当第二过滤器270发生堵塞时，液压马达230的回油管路中的油液能够通过第二旁通阀280回流至油箱210中，从而能够避免整个液压启动系统200因第二过滤器270发生堵塞而立即需要停止运行，即第二旁通阀280的设置能够缓解第二 过滤器270发生堵塞后对液压启动系统200的运行状态的不良影响。
在液压马达230发生异常的情况下，液压马达230的回油管路中的油压可能小于油箱210中的油压，此时可能会导致液压马达230通过第二旁通阀280将油箱210中的油液倒吸至回油管路，甚至倒吸至液压马达230中，进而影响到整个液压启动系统200的运行。为避免上述情况发生，在更进一步的技术方案中，第二旁通阀280可以为单向阀，单向阀在油液从液压马达230流向油箱210的方向导通。在此种情况下，单向阀只能够在液压马达230向油箱210的流动方向上实现导通，从而能够避免油箱210中的油液通过单向阀倒流至液压马达230中，进而对液压启动系统200的正常运转造成影响，继而对整个燃气轮机启动系统的正常运转造成影响。
在本申请实施例公开的燃气轮机启动系统中，液压启动系统200还可以包括蓄能器，蓄能器设置于液压马达230与液压泵220之间的管路上并且导通。在此种情况下，当液压马达230中需要的油量小于液压泵220的出口排出的油量的情况下，蓄能器能够将液压泵220的出口排出的多余的油量暂时储存起来，而当液压马达230中需要的油量大于液压泵220的出口排出的油量的情况下，蓄能器能够将之前储存的油量排出，用以对液压泵220的出口排油量不足的情况实现补偿。也就是说，蓄能器能够稳定液压泵220对液压马达230不同油量大小的需求，从而使得液压马达230能够较为平稳地在不同转速中实现切换，有利于提升燃气轮机300运行过程中的稳定性。
在本申请实施例公开的燃气轮机启动系统中，燃气轮机启动系统还可以包括节温器和散热器，节温器与散热器相连通，节温器与散热器设置于所述液压泵220的出口与液压马达230的进油管路之间，从而使得节温器与散热器能够对液压泵220的出口排出的油液的温度实现调整，进而能够避免液压泵220中的油液的温度过高或过低而影响整个液压启动系统200的正常运行。
本申请实施例公开一种动力设备，所公开的动力设备包括上文中所述的任一项的燃气轮机启动系统。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
