有鉴于此,本发明的目的在于揭露一种喷油螺旋两段式空气压缩机具有一顺向喷油嘴,喷射注入润滑油进入中间冷却室,以增加喷油螺旋两段式空气压缩机的冷却效率。
此喷油螺旋两段式空气压缩机包含有一单体式壳体以及一顺向喷油嘴。单体式壳体更包含有一第一段压缩室、一中间冷却室以及一第二段压缩室。第一段压缩室、中间冷却室以及第二段压缩室平行地堆叠于单体式壳体之中。顺向喷油嘴对准中间冷却室,以平行中间冷却室的方向,喷射注入润滑油进入中间冷却室。
喷油螺旋两段式空气压缩机更包含有一第一段螺旋转子对,设置于第一段压缩室之中,以及一第二段螺旋转子对,设置于第二段压缩室之中。
在一实施例中,单体式壳体更包含有一中间隔板设置于第一段压缩室以及中间冷却室之间,且第一段螺旋转子对的一螺旋转子端部与中间隔板的一隔板端部对齐。
在一实施例中,第一段压缩室更包含有一油气混合压缩空气出口,而第二段压缩室更包含有一油气混合压缩空气入口。
在一实施例中,喷油螺旋两段式空气压缩机更包含有一喷油模块,其中顺向喷油嘴被固定在喷油模块,而喷油模块更包含有一喷油室,以导引在第一段压缩室中被压缩的气体进入中间冷却室。
在一实施例中,喷油螺旋两段式空气压缩机更包含有一前轴承座固定于第一段压缩室以及第二段压缩室的一端,一第一段后轴承座固定于第一段压缩室的另一端,以及一第二段后轴承座固定于第二段压缩室的另一端。
在一实施例中,喷油螺旋两段式空气压缩机更包含有一齿轮箱设置于前轴承座。
在一实施例中,齿轮箱包含有一变速齿轮组以及一传动轴连接于变速齿轮组。
综上所述,根据本发明的一实施例所揭露的喷油螺旋两段式空气压缩机可以利用顺向喷油嘴直接喷射注入润滑油进入中间冷却室,且润滑油喷雾平行于第一段压缩的空气在中间冷却室中的气流方向,因此喷油螺旋两段式空气压缩机的冷却效率可以有效地被提升。
此外,隔板端部向着第一段螺旋转子对的端缘延伸,更有效增加第一段压缩室的压缩效率,同时也增加了整体喷油螺旋两段式空气压缩机的压缩效率。

参阅图1,其是依照本发明一实施例所绘示的一种喷油螺旋两段式空气压缩机的示意图。如图所示,喷油螺旋两段式空气压缩机100包含有一单体式壳体200,一前轴承座110固定于单体式壳体200的一端,一第一段后轴承座130以及一第二段后轴承座140分别固定于单体式壳体200的另一端。
单体式壳体200更包含有一第一段压缩室220,一中间冷却室250,以及一第二段压缩室280。其中,上述的第一段压缩室220、中间冷却室250以及第二段压缩室280平行堆叠地形成于单体式壳体200之中。参阅箭头201代表气体流动的方向,而虚线箭头则代表喷射注入中间冷却室250的润滑油喷雾302。
第一段压缩室220更设置有一第一段螺旋转子对230,安装于第一段压缩室220之中,以压缩由空气入口210吸入的空气形成一第一段压缩空气,而第一段压缩的空气经由第一段空气出口240被排出,以进入中间冷却室250。第二段压缩室280更设置有一第二段转子对282,安装于第二段压缩室280之中,其进一步压缩第一段压缩空气,以形成一第二段压缩空气,第二段压缩空气具有相对于第一段压缩空气较高的压力。第一段压缩的空气由中间冷却室250经由一第二段空气入口270进入第二段压缩室280,以更进一步地在第二段压缩室280中被压缩,以形成第二段压缩空气,并由一第二段空气出口290被排出。
此外,一齿轮箱120被固定于前轴承座110,而齿轮箱120包含有一变速齿轮组122以及一传动轴124连接于变速齿轮组122。传动轴124传输由马达所产生的一动力进入变速齿轮组122,以分配所需的动力至第一段螺旋转子对230以及第二段转子对282。
一顺向喷油嘴304对准中间冷却室250,以喷射注入润滑油喷雾302,进入中间冷却室250,而润滑油喷雾302平行于中间冷却室250。因此,喷油螺旋两段式空气压缩机100的冷却效率被有效地增加。
此外,顺向喷油嘴304可以直接固定于单体式壳体200,以喷射注入润滑油喷雾302进入中间冷却室250。或者,喷油螺旋两段式空气压缩机100更可以包含有一喷油模块300,而顺向喷油嘴304固定于此喷油模块300。喷油模块300则更包含有一喷油室306能够导引第一段压缩的空气进入中间冷却室250,而当第一段压缩的空气进入中间冷却室250时,顺向喷油嘴304以平行于第一段压缩空气的气流方向,喷射注入润滑油喷雾302。
值得注意的是,单体式壳体200更包含有一中间隔板260设置于第一段压缩室220以及中间冷却室250之间,而第一段螺旋转子对230的一螺旋转子端部232对齐中间隔板260的一隔板端部262。换言之,第一段螺旋转子对230的螺旋转子端部232延伸至中间隔板260的隔板端部262的一端缘。
在一实施例中,第一段空气出口240是一油气混合压缩空气出口,而第二段空气入口270是一油气混合压缩空气入口。
在一实施例中,前轴承座110固定在第一段压缩室220以及第二段压缩室280的一端,而第一段后轴承座130则被固定在第一段压缩室220的另一端,此外一第二段后轴承座140则被固定在第二段压缩室280的另一端。
根据本发明的一实施例所揭露的喷油螺旋两段式空气压缩机利用顺向喷油嘴直接喷射注入润滑油进入中间冷却室,且润滑油喷雾平行于第一段压缩的空气在中间冷却室中的气流方向,因此喷油螺旋两段式空气压缩机的冷却效率可以有效地被提升。
此外,隔板端部向着第一段螺旋转子对的端缘延伸,更有效增加第一段压缩室的压缩效率,同时也增加了整体喷油螺旋两段式空气压缩机的压缩效率。因此,本发明所揭露的喷油螺旋两段式空气压缩机的工作效率同时被有效地提升。
虽然本揭露已以实施方式揭露如上,然其并非用以限定本揭露,任何本领域具通常知识者,在不脱离本揭露的精神和范围内,当可作各种的更动与润饰,因此本揭露的保护范围当视后附的权利要求范围所界定者为准。
