Description

平动式旋转压缩装置
技术领域
本发明涉及在气体压缩、流体输送和抽真空领域,尤其涉及一种具有平动活塞的旋转压缩机械。
背景技术
气体压缩机、流体泵和真空泵是重要的通用压缩机械。目前,滚动活塞压缩机械和转子压缩机械作为第二代压缩机械的代表,都具有一个月牙型的工作腔;通过滑板将月牙型的工作腔的隔离成膨胀腔和压缩腔;回转部件(转子或者平动活塞)使膨胀腔和压缩腔的容积变化,实现压缩机械的吸气(液)和排气(液)。但是这两种压缩机械都存在一个问题,即滑板伸入工作腔中通过与缸体或者转子(活塞)接触来隔离膨胀腔和压缩腔,这种接触为线接触,同时接触面有着很高的相对速度;这两个因素决定了该类型压缩机械不能承受很大的压差,磨擦磨损严重;严重时会导致滑板和缸体或者转子(活塞)表面分离,使得密封失效。
大金工业株式会社于上世纪90年代提出一种摇动压缩机械(专利申请号94191130.6),将活塞和滑板作成一体,滑板穿过工作腔进入带导轨的缸体中,将工作腔隔成膨胀腔和压缩腔。导轨可沿缸体摇动,滑板可在导轨中做往复运动,从而使得活塞在转子驱动下做摇动压缩。该结构减少了磨损和泄漏,在制冷压缩行业取得了一些运用。但是其活塞与滑板是一体的,很难加工;缸体内侧需要预留滑板的往复运动空间,使得缸体体积庞大,容易变形;由于结构限制,工作时机器产生的压缩热和摩擦热无法快速排出,散热性能差。
发明内容
为了解决上述的压缩机械所遇到的技术问题,本发明的一个目的是提供一种平动式旋转压缩装置,其具有结构简单、工作效率高的特点。本发明的另外一个目的是提供上述的平动式旋转压缩装置的应用。
为了实现上述的第一个目的,本发明采用了以下的技术方案:
平动式旋转压缩装置,该装置包括缸体、平动活塞和偏心转子,偏心转子设置在缸体内,平动活塞设置在偏心转子上,平动活塞与偏心转子之间活动联接,偏心转子的旋转中心与缸体同心,平动活塞的外侧面保持与圆形缸体内侧面相切,形成有月牙型的工作腔,缸体内壁铰接设有滑板,平动活塞的径向上设有滑板槽,滑板穿过工作腔伸入到滑板槽内,滑板与滑板槽滑动联接,滑板将工作腔分隔成膨胀腔和压缩腔,膨胀腔和压缩腔上分别设有吸入口和排出口。
上述装置的工作原理如下:偏心转子驱动平动活塞沿缸体内壁平动,同时由于铰接滑板的约束,其又相对于缸体做一定幅度的摆动。这种复合运动使得工作腔有规律的变化,在一个工作周期中,膨胀腔体积变大,实现吸气(液);压缩腔体积变小,实现排气(液),完成了吸排(液)过程。
作为优选,上述的平动活塞与偏心转子之间通过滑动轴承或滚动轴承联接。通过滑动轴承或滚动轴承联接,平动活塞与偏心转子之间减少了摩擦损失,提高了机械效率。
作为优选,上述的缸体内壁设有凹形槽,所述的滑板的端头设有柱形凸头,柱形凸头活动容置在凹形槽内形成滑板与缸体内壁的铰接结构。上述的结构具有结构简单、稳定可靠的特点。作为再优选,上述的凹形槽的1/3圆周与圆形缸体连通。
作为优选,上述的平动活塞包括内壁体和外壁体,内壁体和外壁体通过若干放射状设置的连接板连接,连接板之间形成有散热通道。上述结构增加了冷却系统,提高了散热效果和压缩效率。
作为优选,上述的平动活塞设有两块具有平行面的连接板,所述的滑板槽形成在两块连接板之间。上述的结构具有结构简单、稳定可靠的特点。
作为优选,上述的缸体的外圈设有若干散热翅片。
为了实现上述的第二个目的,本发明的压缩装置可以作为压缩机、流体泵以及真空泵使用。
本发明由于采用了以上的技术方案,具有以下的特点:
①使得滑板与缸体(活塞)之间的接触从传统线接触变成现在的面接触,极大降低了泄漏;
②通过滑板约束平动活塞,使其运动方式从高速转动变为低速平动,其与缸体的相对运动速度降低了一个数量级;
③增加了平动活塞内侧的散热通道,可快速冷却活塞;
④取消了用来预紧滑板的弹簧,减少了易损件。
本发明的效果是:该压缩机械与同类型滚动活塞压缩机械和摇动压缩机械相比,泄漏降低,容积效率显著提高,并能得到更高的输出压力;减少了摩擦损失,提高了机械效率;改善了冷却系统,提高了散热效果和压缩效率;减少了弹簧和导轨等易损件,提高机械的可靠性;采用了粉末冶金的异型滑板,简化了加工工艺,使其具备了批量化生产的基础。
本发明与摇动压缩机械的区别在于:平动活塞的回转压缩装置的活塞和滑板是分体的;活塞上开有散热通道和滑板槽;平动活塞与转子之间增加了轴承;滑板铰接在缸体上,可在活塞上的滑板槽内做往复运动;取消了导轨,减少了零件和泄漏通道。这种结构对比摇动压缩机械,在散热、泄漏、加工过程能力、机器体积和零件数量方面有着比较大的提高和改善。
附图说明
图1为本发明的结构示意图。
图2为本发明平动活塞的结构示意图。
图3是本发明的工作原理图。
具体实施方式
下面结合附图对本发明的具体实施方式做一个详细的说明。
如图1所示的平动式旋转压缩装置,该装置包括缸体1、平动活塞2、偏心转子4、轴承5和滑板6。其中,圆环型缸体1是固定的,缸体1的外圈设有若干散热翅片。平动活塞2设置在缸体1内,平动活塞2设置在偏心转子4上并与缸体1的大通孔按偏心设置,平动活塞2与偏心转子4之间通过轴承5活动联接,偏心转子4的旋转中心与缸体1同心,平动活塞2的外侧面保持与圆形缸体1内侧面相切,形成有一个月牙型的工作腔6、7,并且平动活塞2可以绕缸体1的圆心平动。缸体1内壁设有凹形槽10,凹形槽10的1/3圆周与圆形缸体1连通。所述的滑板6的端头设有柱形凸头9,柱形凸头9活动容置在凹形槽10内形成滑板6与缸体1内壁的铰接结构。
如图2所示,平动活塞2包括内壁体13和外壁体14,内壁体13和外壁体14通过若干放射状设置的连接板15连接,连接板15之间形成有散热通道16,并且平动活塞2设有两块具有平行面的连接板15,两块连接板15之间形成有滑板槽8。滑板6穿过工作腔6、7伸入到滑板槽8内,滑板6与滑板槽8滑动联接,滑板6可以在滑板槽8内往复运动,滑板6将工作腔分隔成膨胀腔6和压缩腔7,膨胀腔6和压缩腔7上分别设有吸入口11和排出口12。
当偏心转子4通过轴承5驱动平动活塞2沿顺时针v方向运动时,由于滑板6的约束,平动活塞2只能以缸体1的圆心为中心做近似平动,运动过程中膨胀腔6的容积逐渐变大,将外界的气(液)体吸入,压缩腔7的容积逐渐变变小,将气(液)体排除,从而实现了吸气(液)和排气(液)。活塞上的散热通道16能将压缩产生的热量快速带出。
本发明的工作原理如图3所示:平动活塞2的圆心为O2,缸体1的圆心为O1,缸体1的最高点为A,滑板6圆头的圆心为O3;当机器运行时,平动活塞2以O2O1为半径,绕O1做平动,同时又以O3圆心,以O1O3为半径作轻微摆动,在这过程中,滑板6在滑板槽8中做有规律的往复运动。定义平动活塞2的运动方向为顺时钟,以其圆心O2与滑板6的中心线O1O3重合时为一个工作周期的起始点,旋转角a=∠O2O1A。则在一个周期内a从0°变成360°;当a=0°时,工作腔处于上一周期的吸排气(液)结束状态;随着a的增加,新形成的膨胀腔6逐渐变大,开始将外界的气(液)体吸入;而上一周期的膨胀腔6开始封闭,转变成本工作周期的压缩腔7,将气(液)体排出;到a=360°时,一个周期的吸气(液)过程和排气(液)过程完成。如此循环,实现了平动回转压缩机械的吸排气(液)过程。
