Description

动力系统及压裂设备 技术领域
本申请涉及压裂设备技术领域，具体而言，涉及一种动力系统及压裂设备。
背景技术
涡轮压裂设备具有体积小、重量轻、功率大、燃料经济性好等优点被逐渐推广应用于油田增产作业。一台涡轮压裂设备最大水马力可达5000HP，相当于2台2500HP常规柴油机压裂车。此外，涡轮压裂设备能够100％使用井场天然气作为燃料，大大降低燃料费用，节约作业成本，并大幅降低氮氧化物，二氧化碳和甲烷的排放。
涡轮压裂设备的主要动力构成包括主动力总成部分和辅助动力总成部分。主动力总成部分主要是由涡轮发动机通过减速箱驱动高压柱塞泵进行压裂液的泵送。辅助动力总成部分主要为设备作业前后或作业中的一些附件提供动力，如设备作业前，涡轮发动机排气消音器盖板的打开、主动力总成部分的涡轮发动机的启动以及主动力总成部分中的减速箱刹车；设备作业过程中，对减速箱、柱塞泵内部各摩擦副的强制润滑以及各系统的散热；设备作业结束后，涡轮发动机排气消音器盖板的关闭都通过辅助动力总成部分驱动润滑系统实现的。
涡轮压裂设备的辅助动力总成部分采用的是多个电动机分别直接驱动执行驱动部件和电动机驱动一套液压系统，液压系统再驱动余下执行部件相结合的方式，实现各辅助功能。其中，柱塞泵高压润滑泵、柱塞泵低压润滑泵、减速箱润滑泵、涡轮发动机舱体换气扇、柱塞泵润滑油散热器风扇、液压油\涡轮发动机润滑油\减速箱油散热器风扇、涡轮发动机燃油泵、空压机分别由独立的电动机进行驱动；余下的执行部件消音器下盖板油缸、消音器上盖板油缸、涡轮发动机启动马达、减速箱刹车钳、控制阀由电动机驱动液压系统实现。液压系统由两台电动机分别驱动两台液压泵，一台液压泵为涡轮发动机启动马达提供动力，另一台液压泵为消音器下盖板油缸、消音器上盖板油缸、减速箱刹车钳、控制阀提供动力。
可见，减速箱润滑系统是通过减速箱润滑电机驱动减速箱润滑泵，润滑泵从减速箱润滑油箱吸油后，泵送到减速箱内部润滑点。液压系统包含了两台液压泵，电动机一驱动液压泵一从液压油箱吸油后，为涡轮发动机启动马达提供动力；电动机二驱动液压泵二从液压油箱吸油后，为消音上盖板油缸、减速箱刹车钳、控制阀提供动力。
液压系统与减速箱润滑系统二者为毫无关联的系统，需要分别配备独立的液压油箱、电动机一、液压泵一、电动机二、液压泵二；以及减速箱润滑油箱、减速箱润滑电机、减速箱润滑泵。因部件较多，使设备整体空间更紧凑、弱化了后期设备维便利性，且使设备的整体造价更高。

应该指出，以下详细说明都是例示性的，旨在对本申请提供进一步的说明。除非另有指明，本文使用的所有技术和科学术语具有与本申请所属技术领域的普通技术人员通常理解的相同含义。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
本申请提供了一种动力系统，请参考图1，包括：油箱10；减速箱20，具有润滑系统，润滑系统与油箱10相连通；液压系统，包括液压执行元件，液压执行元件与油箱10相连通。
本申请的动力系统包括油箱10、减速箱20和液压系统，液压系统包括液压执行元件，减速箱20的润滑系统和液压执行元件均与油箱10相连通，油箱10中的油液用于对减速箱20进行润滑，也用于为液压执行元件提供动力。润滑系统和液压系统共用一个油箱，避免润滑 系统和液压执行元件分别用两个独立的油箱供油所导致的动力系统的零部件较多的问题，减小了零部件所占用空间，优化了动力系统的空间布置情况，腾出更多的空间，便于后期设备维修，且降低了动力系统的成本。
具体实施时，通过对减速箱所需要的润滑油和液压系统的液压油油品性质的对比，两种油品在不同温度下粘度相近，因此，确定润滑系统和液压系统的工作介质能够使用同种油品。
在本实施例中，液压系统包括多个液压执行元件，多个液压执行元件包括用于与压裂设备的发动机连接的马达30；动力系统还包括：第一液压泵40，第一液压泵40的进口与油箱10相连通；切换部件50，第一液压泵40的出口通过切换部件50与润滑系统的进入端相连通，第一液压泵40的出口通过切换部件50与马达30的进口相连通；切换部件50具有使第一液压泵40的出口与润滑系统的进入端相连通且使第一液压泵40的出口与马达30的进口相断开的第一连通状态和使第一液压泵40的出口与润滑系统的进入端相断开且使第一液压泵40的出口与马达30的进口相连通的第二连通状态，切换部件50在第一连通状态和第二连通状态之间切换；润滑系统的输出端和马达30的出口均与油箱10相连通。其中，马达30用于启动压裂设备的发动机。
具体实施时，因为润滑系统所需的油量与液压系统的马达30启动发动机所需的油量相近，且二者不同时工作，故通过切换部件50在第一连通状态和第二连通状态的切换作用，实现第一液压泵40对润滑系统和马达30的油液的供给；并且，通过切换部件50的切换作用，单个第一液压泵40即可实现对减速箱20的润滑和控制马达30工作，降低了成本。
在本实施例中，切换部件50为电磁阀。当电磁阀不通电时，第一驱动件60驱动第一液压泵40为减速箱的润滑系统提供润滑油，当电磁阀通电时，第一驱动件60驱动液压泵为马达30提供动力。电磁阀在第一连通状态和第二连通状态切换时更方便快捷，切换迅速，并且，电磁阀可以连接控制系统，更容易远程操控以切换连通状态。
在本实施例中，动力系统还包括第一驱动件60，第一驱动件60与第一液压泵40驱动连接。
具体实施时，第一驱动件60的设置使第一液压泵40可以被驱动，从而产生在油箱10中吸油的效果，为油液流向润滑系统和马达30提供了动力。
在本实施例中，第一驱动件60为电动机。
在本实施例中，动力系统还包括：第一连接管70，第一连接管70的第一端与第一液压泵40的出口连接且相连通，第一连接管70的第二端与切换部件50连接且相连通；第二连接管80，第二连接管80的第一端与油箱10相连通，马达30的出口和润滑系统的输出端均与第二连接管80相连通；第三连接管90，第三连接管90的第一端与第一连接管70连接且连通，第三连接管90的第二端与第二连接管80连接且相连通，第三连接管90的第二端位于马达30的出口和第二连接管80的第一端之间，第三连接管90的第二端位于润滑系统的输出端和第二连接管80的第一端之间；其中，第三连接管90上设置有安全阀100。
具体实施时，第一连接管70用于将油箱10中的油液输送进入润滑系统和马达30中；第二连接管80用于将润滑系统和马达30中排出的油回流至油箱10中，第一连接管70与第二连接管80使动力系统中的油路形成了循环；第三连接管90上设置安全阀100保证了第一液压泵40的安全运行，进而保证了动力系统的安全性。
在本实施例中，动力系统还包括：第二连接管80，第二连接管80的第一端与油箱10相连通，马达30的出口和润滑系统的输出端均与第二连接管80相连通；第四连接管110，第四连接管110的第一端与切换部件50连接且相连通，第四连接管110的第二端与润滑系统的进入端相连通；第五连接管120，第五连接管120的第一端与第一连接管70连接且相连通，第五连接管120的第二端与第二连接管80连接且相连通，第五连接管120的第二端位于马达30的出口和润滑系统的输出端之间；其中，第五连接管120上设置有溢流阀130。
具体实施时，第四连接管110的设置将切换部件50出口的油液输送至润滑系统的进入端，使减速箱20能够得到润滑；第五连接管120上设置的溢流阀130避免压力超过允许值，从而保证系统不因压力过高而发生事故。
在本实施例中，液压系统包括多个液压执行元件，多个液压执行元件包括至少一个第一液压执行元件；动力系统还包括：第二液压泵140，第二液压泵140的进口与油箱10相连通，第二液压泵140的出口与至少一个第一液压执行元件相连通；其中，至少一个第一液压执行元件包括控制阀150、减速箱20的刹车21、用于与消音器的第一盖板连接的第一油缸160和用于与消音器的第二盖板连接的第二油缸170中的至少一个。
具体实施时，第二液压泵140的设置是为了将油箱10内的油液抽送至控制阀150、减速箱20的刹车21、第一油缸160和第二油缸170。
具体地，控制阀150为CGV(COMPRESSOR GUIDE VANE)控制阀；在油液的作用下，第一油缸160控制第一盖板发生动作，第二油缸170控制第二盖板发生动作。
在本实施例中，动力系统还包括第二驱动件180，第二驱动件180与第二液压泵140驱动连接；其中，第二驱动件180为电动机。第二驱动件180使第二液压泵140在油箱10中抽取油液并抽送至各个液压执行元件，使液压执行元件发生动作。
具体地，动力系统还包括蓄能器190和卸荷阀200，卸荷阀200的入口与第二液压泵140的出口相连通，蓄能器190与卸荷阀200的出口相连通，蓄能器190与各个第一液压执行元件均相连通。具体实施时，第二驱动件180驱动第二液压泵140从油箱10内吸油后，将油液泵入蓄能器190，当蓄能器190内压力达到卸荷阀200的设定压力时，第二液压泵140实现卸载，当蓄能器190内压力低于卸荷阀200的设定压力的85％时，第二液压泵140重新向蓄能器190内部输送油液，如此反复。蓄能器190内储存的油液，为控制阀、刹车、第一油缸和第二油缸提供动力。具体地，减速箱20的刹车21、第一油缸160和第二油缸170均通过电磁阀与蓄能器190连接。
本申请还提供了一种压裂设备，包括上述实施例中的动力系统。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：
本申请的动力系统包括油箱10、减速箱20和液压系统，液压系统包括液压执行元件，减速箱20的润滑系统和液压执行元件均与油箱10相连通，油箱10中的油液用于对减速箱20进行润滑，也用于为液压执行元件提供动力。润滑系统和液压系统共用一个油箱，避免润滑系统和液压执行元件分别用两个独立的油箱供油所导致的动力系统的零部件较多的问题，减小了零部件所占用空间，优化了动力系统的空间布置情况，腾出更多的空间，便于后期设备维修，且降低了动力系统的成本。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必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，以便这里描述的本申请的实施方式例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
