如图1和图2所示，本申请实施例提供一种油分离器，油分离器包括筒体10和进气管20。其中，筒体10的侧壁具有进气孔11，进气孔11的轴线与筒体10的轴线不相交，进气管20穿设在进气孔11内，并与筒体10的内部连通。
应用本申请的技术方案，将进气孔11的轴线与筒体10轴线不相交，可以使流体进入筒体10时增加离心效果，进而能够促进流体气液分离，提高了装置的分离效率和分离效果。通过上述结构可以在便于进气孔11与进气管20焊接的同时提高进气孔11与进气管20的连接强度。
具体地，进气管20的位于筒体10内部的端面设计为斜面。如此能够进一步提高流体进入筒体10的离心效果。
其中，进气孔11的周缘还设置有环形翻边111，环形翻边111可以设置在筒体10的内侧，也可设置在筒体10的外侧，进气管20与环形翻边111连接。如此可根据装置的实际使用需求来设置翻边的具体位置，从而能够提高装置的适用范围。在本实施例中，环形翻边111设置在筒体10的外侧。将进气孔11的周缘处设置有环形翻边111，在安装过程中，进气管20的外壁与环形翻边111进行接触，且进气管20的一端与筒体10内部连通，如此可以提高进气管20与筒体10之间的接触面积。
在本申请的其它实施例中，环形翻边111贯穿进气孔11的两侧，进气管20与环形翻边111连接。如此进一步提高了进气孔11与进气管20的接触面积，从而能够进一步提高进气孔11与进气管20的焊接强度，保证装置运行时的稳定性。
其中，环形翻边111的端面可以为平面、弧面，也可设置为斜面。只要能够便于进气管20与进气孔11连接即可。
如图4所示，环形翻边111具有相对设置的连接端和自由端1112，环形翻边111的自由端1112凸出筒体10的外侧壁设置，环形翻边111的自由端1112的端面为平面。通过设置上述结构，将环形翻边111的一端面设置为平面，如此在安装过程中便于进气管20伸入进气孔11内，从而便于进气管20与进气孔11的焊接，提高了装置的安装效率。
如图5所示，环形翻边111具有相对设置的连接端和自由端1112，环形翻边111的自由端1112凸出筒体10的外侧壁设置，环形翻边111的自由端1112的端面为弧面。上述设置结构简单，将环形翻边111的一端设置为弧面，如此便于环形翻边111的加工，从而有利于降低装置的生产成本。
具体地，在环形翻边111的自由端1112的端面为弧面的情况下，弧面与筒体10的外侧壁表面的间距相同。上述设置，使得环形翻边111的自由端1112延伸方向的曲率与筒体10外壁相等，如此能够保证装置整体结构的一致性，且方便加工，降低了加工成本。
进一步地，环形翻边111的轴线与进气孔11的轴线重合。上述设置，能够保证环形翻边111与进气孔11结构的一致性，从而进一步保证了进气孔11与进气管20焊接后整体的结构强度，并且该结构方便将进气管20穿设进进气孔11内。
具体地，环形翻边111的高度大于或者等于0.5mm。通过设置上述结构，在保证环形翻边111与进气管20具有足够的接触面积的同时合理地利用了筒体10内、外壁空间。其中，环形翻边111的高度可设置为0.5mm、1mm或者1.5mm等。
进一步地，油分离器为不锈钢材质。上述材料结构简单易于加工，在降低装置生产成本的同时能够有效地减小装置的重量，从而保证了装置的轻量化。其中，在本申请的其他实施例中，油分离器的材料还可设置为其它金属材质，具体可根据装置的使用环境选择不同的材料，如此能够提高装置的适用范围。
进一步地，进气管20与进气孔11为钎焊或者氩弧焊连接。通过上述焊接方式，进一步保证进气管20与进气孔11焊接后的结构强度，在保证装置运行的稳定性的同时能够延长了装置的使用寿命。其中，在本申请的气体实施例中，进气管20与进气孔11还可采用其他方式进行连接固定，只要保证进气管20与进气孔11连接后装置的工作性能即可。
其中，油分离器还包括出气管30，出气管30的位于筒体10内部的外径小于出气管30的位于筒体10外部的外径，如此能够限制出气管30的连接深度，同时出气管30与筒体10的焊接处设置有拉花，从而使得焊接时焊接处有充足的焊料，能够保证焊接后的结构强度。
如图3所示，本申请又一实施例提供了一种油分离器，与上述实施例不同之处在于，本申请中的环形翻边111设置在筒体10的内侧。
应用本申请的技术方案，将进气孔11的轴线与筒体10轴线不相交，可以使流体进入筒体10时增加离心效果，进而能够促进流体气液分离，提高了装置的分离效率和分离效果。将进气孔11的周缘处设置有环形翻边111，在安装过程中，进气管20的外壁与环形翻边111进行接触，且进气管20的一端与筒体10内部连通，如此可以提高进气管20与筒体10之间的接触面积，通过上述结构可以在便于进气孔11与进气管20焊接的同时提高进气孔11与进气管20的连接强度。同时，环形翻边111设置在筒体10的内侧或筒体10的外侧。如此可根据装置的实际使用需求来设置翻边的具体位置，从而能够提高装置的适用范围。
