Description

在管路中的油分离器
技术领域
本发明涉及在压缩机内从制冷剂中分离出油,尤其涉及在螺杆式压缩机的排气端处从制冷剂中分离出油。
背景技术
螺杆式压缩机或螺旋式压缩机广泛地用于空调应用场合,以便在制冷循环的一部分中压缩制冷剂。螺杆式压缩机包括啮合的螺杆转子或螺旋转子。尽管两个转子结构是最常用的结构,但是在本领域内具有三个或多个转子的螺杆式压缩机也是公知的,这些转子容纳在各自的重叠的缸孔内,以便成对地相互配合。典型的螺杆式压缩机的转子安装在处于壳体端板中位于入口和排气侧上的轴承上。制冷剂由螺杆转子朝向排气侧压缩并经过端口排放到排气管路中。
在常规的应用场合中,因为当制冷剂流过并压缩时需要润滑螺杆式压缩机的轴承和转子,所以油夹带在制冷剂中,因此需要在排气之后且在进入到制冷循环或空调循环的其余部分之前除去油。因此,油和制冷剂的混合物输送经过该压缩循环并随后排放到油分离器中,在该油分离器中,油从制冷剂中分离出来。制冷剂从该油分离器流向该冷凝器。
油分离器通常为两种形式,立式或卧式。卧式油分离器通常呈圆柱体形状,其中在一个端部处具有入口。在卧式油分离器中,油和制冷剂的混合物通过该入口进入。该混合物流向该分离器的内表面,以便使得油滴撞击到该表面上并被收集。在该流动和重力的作用下,油往往会收集在分离器的底部附近的特别部分,其中油通过排出口被排出。或者可选的是,网孔分离器或挡板用于增大油在其上收集的撞击表面。制冷剂随后从位于油收集区域之上的分离器上部离开。
发明内容
本发明的一目的在于提供一种用于螺杆式压缩机的改进的油分离装置。
本发明的另一目的在于提供一种使用在螺杆式压缩机的排出管路中的简单且有效的油分离装置。
本发明的又一目的在于提供一种油分离装置,其使用排出管路和重力作为用于实现油分离的装置。
本发明的再一目的在于提供一种具有简单且低成本的结构的油分离装置。
本发明的这些和其它的目的通过使用本发明的用于从制冷剂中分离出油的油分离器来实现。该油分离器包括:具有内表面的排出管路;在该排出管路中用于形成在该排出管路中的入口和出口的结构,其中入口的直径比出口扩宽;以及用于防止油从该出口离开的结构,和用于将该油从该排出管路中引导出的装置。在一个实施例中,该结构是大致圆形的壁,并且起到防止作用的该结构是该壁的形状以及该壁相对于该排出管路的相对取向。在一个实施例中,该相对取向如此确定,即,使得该排出管路具有一带有水平分量取向的流动方向,并且该壁具有相对于该水平分量的垂直分量取向。
附图说明
参照附图并结合以下的详细描述可更好地理解本发明,在附图中:
图1是螺杆式压缩机的示意图,其示出了排出端和与排出管路的连接;
图2是油分离器的截面图,其示出了本发明的油分离器结构;
图3是沿图3的线3-3截取的截面图,其示出了油在分离器上向下流动;和
图4是图2所示的油分离器的替代实施例。
具体实施方式
现参照附图进行详细描述,在图1中示出了螺杆式压缩机的示意截面图。该螺杆式压缩机包括壳体12、相互啮合的转子14、制冷剂入口18、以及排出端20,该排出端包括排出板22以及与排出管路26连接的排出壳体24。在操作中,假定转子14中的一个转子是驱动转子,转子14旋转地与另一个转子啮合,以使其旋转。旋转的转子14的共同动作使得制冷剂气体经吸入入口18吸入到转子14的凹槽中,转子啮合以便收集并压缩气体的体积,并且将热的压缩后的制冷剂气体输送到排出端20。
本发明的油分离器28设计成位于排出管26中,如图2所示。油分离器28包括挡油件30、止回阀49、和回油孔48。当压缩后的气态制冷剂从排出端20排放到排出管26时,油分离器28用于在制冷剂流向冷凝器之前将油从制冷剂中去除。
因此,油分离器28优选地呈圆形,其具有带有入口31的中心开口,其中壁32形成该开口并在曲线形基部上轴向地且径向地从入口31延伸到出口34。如图所示,油分离器28的水平轴线X沿与制冷剂R流动的相同方向延伸,如箭头所示。壁32从油分离器28的端面36延伸到排出管26的内壁上,并且油分离器28借助已知的方法例如焊接从而固定到该壁上。当制冷剂蒸气流经该排出管26,油0附着在排出管的壁38上并且沿蒸气流动方向流动。因此,油0沿壁38流动,直到油到达由壁32、38形成的挡油部分40,并且由此防止油进一步经该挡油部分40行进,同时大部分油从其中分离出来的制冷剂蒸气继续行进经过制冷或空调循环。在油分离器28的上端部42上,油聚集在挡油部分40中,并且在重力G的作用下如图3中箭头所示地在壁32的外表面和壁38的内表面上向下流到下端部44。油沿壁38的下端部46流向位于回油孔48附近的由壁32、38形成的下挡油部分41,(该回油孔如图3中虚线所示)。回油孔48垂直地向下延伸,通过重力G的作用,从油分离器28的挡油部分40中传送多余的油。经回油孔48传送的油回收到用于润滑螺杆轴承和转子的油槽中。可选择的是,除了重力G的作用之外或与重力G区分开,油分离器与油槽之间的压力差还可用于经回油孔48传送油。如图2所示,油分离器28可选地包括止回阀49,该止回阀铰接在出口34的上部处,以防止在系统不工作时制冷剂经压缩机回流。
可选的是,如图4所示,壁32可包括唇部50,以便进一步将油的流动保持在壁32的外侧上。另外,挡油件不是必须具有完全垂直的取向;油分离器的取向的垂直分量可实现油在重力的作用下向下流并流到返回管,必需通过系统和排出管路的结构,使得倾斜的取向可实现所需的效果。
尽管参照优选实施例和特定形式的压缩机来描述本发明,但是本领域的普通技术人员应当理解,可在本发明的精神和范围内进行各种变型和改变,因此本发明的范围仅由后附的权利要求来限定。
