Description
本申请属于容积泵技术领域，涉及双转子回转式容积泵，特别涉及一种用于水面航行器无轴推进使用的喷射泵。
传统的水面航行器是采用轴流泵、混流泵、螺旋桨为基础的叶片泵作为推进装置，叶片泵只能在最佳设计工况点附近才能发挥效率，脱离最佳设计工况点，效率直线下降，且有较大的限制工作区域(年不超过500—50小时)。
叶片泵安装位置不可调整，喷口与泵体只能是轴向安装，一泵一喷口，喷口的方向不能改变。
叶片泵存在理论转速下限，且低于额定转速时效率急剧下降，因此无法调控流量、能耗。目前空化、空泡问题是影响叶片泵喷水推进器效率的关键。高航速导致叶片泵吸入大量空气。喷水推进效率下降。因此，无法在航速超过50节的船舶上使用。
叶片泵依靠叶轮旋转速度产生对水的作用力，噪音大。
叶片泵叶轮材料非钢即铜，摩擦损耗大，阻力大，使用寿命短，而且重量大。
叶片泵的叶轮按抛物线角度加工，直径增大，难度增加，不利于大型化。
目前，水面航行器的发展趋势是高航速、高效率、低噪声、低损耗，易维护，因此急需研发一种新式的喷射泵，以取代传统的叶片泵。

实施例一，请参照图1、图2、图3、图4、图5、图6、图7、图8、图9，本申请提供一种双转子回转式容积泵，包括泵壳1、前端盖2、后端盖3、主转子10,副转子20，前端盖2、后端盖3分别安装在泵壳1的前端
和后端，前端盖2和后端盖3中的其中一者可以与所述泵壳一体制成，以增强整个双转子回转式容积泵的紧凑型和密封性。前端盖2上设置有上、下轴承座4、5，后端盖3上设置有上、下轴承座6、7，每个轴承座内装有轴承和油封，请参照图9，下轴承座7内装有轴承18和油封19，泵壳1内设置有上腔8和下腔9，泵壳下腔9侧壁上设置有进水口14、出水口15，主转子10安装在泵壳下腔9中，副转子20安装在泵壳上腔8中，主转子10由主传动轴11和两个凸轮12、13构成，这些凸轮12、13环绕主传动轴11周向均布(在其他的可选的实施方式中，凸轮12、13环绕主传动轴11周向非均匀分布)，副转子20由副传动轴21和带有凸轮槽22、23的圆柱体25构成，凸轮槽22、23的数量与主转子上凸轮12、13的数量相同，副传动轴21设置在圆柱体25的中心，主传动轴11由前、后端盖下轴承座5、7中的轴承支承，副传动轴21由前、后端盖上轴承座4、6中的轴承支承，主转子10上安装的凸轮12、13与泵壳下腔9内壁相切，从而减少摩擦损耗，泵壳下腔9为工作腔，主转子10上安装的凸轮12、13形成了分隔壁，将泵壳下腔9分成高压区和低压区。构成副转子20的圆柱体25与泵壳上腔8内壁相切，主转子10上安装的凸轮与副转子上的凸轮槽相吻合，副转子20起过渡密封作用，使主转子10在旋转过程中，周期性在工作腔中形成高压区和低压区，利用低压吸入流体，利用高压挤出流体。两个凸轮12、13可以实现在175-185度范围内出水。
在本发明提供的双转子回转式容积泵中，主转子10上安装的凸轮12、13与泵壳下腔9内壁相切，构成副转子20的圆柱体25与泵壳上腔8内壁相切，由于这种相切结构分割成的密封的两个子腔(如图6中所示，凸轮
12、13左侧为一个子腔，右侧为另一个子腔；两个子腔中的其中一个为高压区，另一个为低压区)，使得该双转子回转式容积泵的效率大大提高，在零转以上即有效率，也就是说，只要驱动主转子转动，副转子便被动随着主转子同步转动，出水口便输出液体。
主传动轴11的外端装有主动齿轮16，副传动轴21的外端装有被动齿轮17，主动齿轮16与被动齿轮17相啮合，主传动轴11的外端轴头装有皮带轮，皮带轮在外部动力源的带动下高速旋转，主动齿轮16、被动齿轮17同步反向旋转，主传动轴11和副传动轴21也同步反向旋转，主转子和副转子也同步反向旋转，由于凸轮12、13形成分隔壁，将泵壳下腔分成了高压区和低压区，进水口设置在低压区，出水口设置在高压区。当主转子开始旋转后，进水口吸入流体，经过加压后，由出水口排出，可以作为喷射泵使用。
通过上述描述可知，本发明提供的双转子回转式容积泵包括主转子10和副转子20两个转子，两个转子分别由主传动轴11和副传动轴21带动旋转。具体地，主传动轴11是在外部动力源的带动下高速旋转的，而副传动轴21是通过与主传动轴11之间的传动机构(主动齿轮16与被动齿轮17相啮合)被动旋转的，也就是说，两个转子中只有主转子10是在外部动力源的驱动下旋转的，副转子20不需要外部驱动，副转子20只需在主转子的带动下随之旋转即可。因此，本发明中的双转子回转式容积泵，与其他需要同时驱动两个转子的液压泵(转速最高为500r/min)相比，转速大大提高(本发明的转速可以达到1200r/min)，因此，在相同容积的液压泵中，本发明的双转子容积泵的流量大大提高，功率大大提高。
实施例二，请参照图10，图11、图12、图13、图14，本申请提供一种双转子回转式容积泵，其主体结构与上述实施例一相同，包括泵壳、前端盖、后端盖、主转子、副转子，前端盖、后端盖分别安装在泵壳的前端和后端，前端盖上设置有上、下轴承座，后端盖上设置有上、下轴承座，泵壳内设置有上腔和下腔，泵壳下腔侧壁上设置有进水口、出水口，主转子安装在泵壳下腔中，副转子安装在泵壳上腔中，其不同之处在于:
主转子30由主传动轴31和三个凸轮32、33、34构成，这些凸轮32、33、34环绕主传动轴31周向均布(在其他的可选的实施方式中，凸轮32、33、34环绕主传动轴31周向非均匀分布)，副转子40由副传动轴41和带有凸轮槽42、43、44的圆柱体45构成，凸轮槽42、43、44的数量与主转子上凸轮32,33,34的数量相同，副传动轴41设置在圆柱体45的中心，主转子上安装的凸轮32、33、34与泵壳下腔9的内壁相切，构成副转子40的圆柱体45与泵壳上腔8的内壁相切，主转子上安装的凸轮32、33、34与副转子上的凸轮槽42、43、44相吻合。三个凸轮32、33、34可以实现在115-125度范围内出水。
实施例三，请参照图15、图16、图17、图18，本申请提供一种双转子回转式容积泵，其主体结构与上述实施例一相同，包括泵壳、前端盖、后端盖、主转子、副转子，前端盖、后端盖分别安装在泵壳的前端和后端，前端盖上设置有上、下轴承座，后端盖上设置有上、下轴承座，泵壳内设置有上腔和下腔，泵壳下腔侧壁上设置有进水口、出水口，主转子安装在泵壳下腔中，副转子安装在泵壳上腔中，副转子20由副传动轴21和带有
凸轮槽22、23的圆柱体25构成，凸轮槽22、23的数量与主转子上凸轮12、13的数量相同，副传动轴21设置在圆柱体25的中心，其不同之处在于:
主转子50由主传动轴51和两个凸轮52、53构成，这些凸轮52、53环绕主传动轴51周向均布(在其他的可选的实施方式中，凸轮52、53环绕主传动轴51周向非均匀分布)，凸轮52的左、右两侧对应的设置有缺口521、523，凸轮53的左、右两侧对应的设置有缺口531、532，设置缺口的目的是减轻凸轮的重量，同时增加工作腔的容积，可以吸入和排出更多的流体。
实施例四，请参照图19、图20、图21、图22，本申请提供一种双转子回转式容积泵，其主体结构与上述实施例二相同，包括泵壳、前端盖、后端盖、主转子、副转子，前端盖、后端盖分别安装在泵壳的前端和后端，前端盖上设置有上、下轴承座，后端盖上设置有上、下轴承座，泵壳内设置有上腔和下腔，泵壳下腔侧壁上设置有进水口、出水口，主转子安装在泵壳下腔中，副转子安装在泵壳上腔中，副转子40由副传动轴41和带有凸轮槽42、43、44的圆柱体45构成，凸轮槽42、43、44的数量与主转子上凸轮32、33、34的数量相同，副传动轴41设置在圆柱体45的中心，其不同之处在于:
主转子60由主传动轴61和三个凸轮62、63、64构成，这些凸轮62、63、64环绕主传动轴61周向均布(在其他的可选的实施方式中，凸轮62、63、64环绕主传动轴61周向非均匀分布)，凸轮62的左、右两侧对应的设置有缺日621、622，凸轮63的左、右两侧对应的设置有缺口631、632,凸轮64的左、右两侧对应的设置有缺口641、642，设置缺口的目的是减轻
凸轮的重量，同时增加工作腔的容积，可以吸入和排出更多的流体，从而增加该双转子回转式容积泵的输出流量。
实施例五，本申请提供一种双转子回转式容积泵，其不同之处在于:本实施例中的双转子回转式容积泵还可以包括靠近所述进水口14设置的进气口，以在吸入水的同时吸入气体。吸入气体可以是空气也可以是其他不与吸入的液体反应的气体(例如氮气)。进气口可以设置在泵壳1下腔侧壁上，也可以设置在图3中所示的进气口所在的部件的侧壁上。具体地，图3中的进气口所在的部件可以与泵壳1一体制成，以增强整个双转子回转式容积泵的紧凑型和密封性。
由于液体是不能压缩、气体可以压缩，因此该容积泵在通过进水口将液体吸入的同时，气体通过进气口吸入，气体和液体的混合物在低压区吸入，在高压区被压缩，压缩出来的“汽液”混合喷流，大大提高了做功效率。当该容积泵作为喷射泵使用时，射程能够大大提高。加入适量空气后，该容积泵转动的阻力减小，转速加快，“汽液”混合喷流，能够产生较大的推力。
其中，加入的气体(例如空气)的比例可根据需要设定，例如加入15％—40％的空气，可增加20％-35％的效率。
具体地，当该双转子回转式容积泵的进水口与待吸入液体的上表面处于同一高度，或者该双转子回转式容积泵的进水口位于待吸入液体的液面以下时，该双转子回转式容积泵的自吸力为零，可以加入最多的空气。
当该双转子回转式容积泵的进水口位于待吸入液体的液面以上时，则该双转子回转式容积泵的进水口与待吸入液体的液面之间的高度差越大，
该双转子回转式容积泵的进水管道越长，自吸力越大，则可以加入较少的空气；反之，该双转子回转式容积泵的进水口与待吸入液体的液面之间的高度差越小，进水管道越短，自吸力越小，则可以加入较多的空气。
此外，所述进气口连接进气管，所述进气管的第一端与所述泵壳1的内部连通，所述进气管的第二端与大气连通。也就是说，进气管将大气与泵壳1的内部连通。
进一步地，所述进气管上设有阀门。阀门可以用于气体是否进入泵壳1内部，当阀门开启时，进气管将大气与泵壳1的内部连通，空气可以进入泵壳1内部；当阀门关闭时，进气管将大气与泵壳1的内部隔离，空气不可以进入泵壳1内部。阀门可以是各种适合的阀门，例如机械阀、电磁阀；手动阀、自动阀；流量控制阀等。
加入的空气的比例可以通过改变进气管的内壁的横截面积来调节，也可以通过控制阀门来调节。当阀门还用于控制进气管内的气体的流量时，可以是流量控制阀或者其他能够实现流量调节功能的阀门。
实施例六，请参照图23和图24，本申请提供一种双转子回转式容积泵，其主体结构与上述实施例相同，包括泵壳1、前端盖2、后端盖3、主转子、副转子，前端盖、后端盖分别安装在泵壳的前端和后端，前端盖上设置有上、下轴承座，后端盖上设置有上、下轴承座，泵壳内设置有上腔和下腔，泵壳下腔侧壁上设置有进水口14、出水口15，主转子安装在泵壳下腔中，副转子安装在泵壳上腔中，其不同之处在于:本实施例中的双转子回转式容积泵的前端盖2与泵壳1一体制成。可选地，前端盖3也可以与泵壳1一
体制成。前端盖2和后端盖3中的其中一者与所述泵壳一体制成，能够增加该双转子回转式容积泵的密封性和紧凑性，降低生产加工难度。
此外，如图24所示，本实施例中的双转子回转式容积泵还可以包括齿轮箱70，所述齿轮箱70与泵壳1的外壁连接，主动齿轮16和被动齿轮17(参照图)设置在该齿轮箱70内。齿轮箱70将主动齿轮16和被动齿轮17包裹在内，避免主动齿轮16和被动齿轮17受到外界的损害，保证主动齿轮16和被动齿轮17顺畅传动。
齿轮箱70包括腔体和密封腔体的防尘盖(图未示)，齿轮箱70可以为椭圆形。
另外，本申请的双转子回转式容积泵呈葫芦形，如图5、图6、图10、图11、图12、图15、图16、图17、图19、图20和图21所示，上腔8的容积小于下腔9的容积。也就是说，副转子20所在的上腔8的容积小于主转子10所在的下腔9的容积。具体地，下腔9的容积可以是上腔8的容积的1.5倍、两倍、三倍、四倍或者其他合适的比值。副转子20与主转子10同步旋转，起到密封的作用；主转子旋转形成高压区和低压区，起到输出流量的作用。本申请中只有主转子10的转动输出流量，也就是说，只有主转子10推动液体流出，即只有主转子10旋转向外输出流量，因此转速能够达到很高。
本申请与相同转速的液压泵相比，本申请的双转子回转式液压泵内部容积大，因此相同时间内输出的流量大。
本申请的双转子回转式液压泵只有一个转子(即主转子10)输出流量，转速可以达到很高，因此，与相同容积的液压泵相比，在相同的时间内能够输出更多的流量。
在本申请的上述实施例中，优选地，凸轮环绕主传动轴的周向均匀分布，如图5、图6、图10、图11、图13、图15、图16、图19和图20所示。例如，在图6所示的实施方式，凸轮个数为二，此时两个凸轮之间的角度为180°；在图11所示的实施方式中，凸轮个数为三，此时，三个凸轮之间的角度为120°。凸轮均匀分布，则任意相邻的两个凸轮与泵壳1内壁之间的容积是相等的，可以吸入和排出相同的流体，因而该双转子回转式容积泵能够输出稳定的流量。
当凸轮环绕主传动轴的周向非均匀分布时，相邻凸轮之间的角度可以任意设定角度。例如，当凸轮个数为二时，两个凸轮之间的角度可以是190°、170°、160°等。
本申请提供的双转子回转式容积泵，结构简单，加工容易，成本低，重量轻，工作区域宽、效率高，流量大，使用寿命长，噪音低，用途广泛。
