Description

压缩机滑片的表面处理方面
技术领域
本发明涉及压缩机技术领域,尤其是一种压缩机滑片的表面处理方法。
背景技术
滑片压缩机体积小、重量轻、运行平稳和容积效率高,被广泛应用于各种空气压缩、小型制冷空调以及食品机械中。这种滑片压缩机在运转时,滑片随转子做旋转运动,滑片在离心力和滑槽中流体压力的共同作用下甩出滑槽,贴紧缸体壁面不断移动,运转过程中,滑片的摩擦损耗主要发生在滑片侧面和滑槽之间以及滑片顶部与缸体之间。传统的滑片主要依靠润滑油来减小摩擦损耗,但在使用一段时间后,润滑条件因各种因素而不断恶化,使得滑片表面磨损急速增大,由此导致压缩机效率降低,滑片严重磨损时,压缩机易堵转失效。对滑片进行表面处理可以延长滑片的寿命,新冷媒如CO2的使用大幅度提高了压缩机工作压力,从而提高了对滑片的强度和耐磨性要求,但是现有的表面渗氮处理工艺得到的产品质量不理想,已经无法满足这种要求,滑片的强度和耐磨性需要得到进一步的提高。
发明内容
本发明的目的是提供一种压缩机滑片的表面处理方法,这种方法可以解决现有压缩机滑片的表面处理方法存在处理得到的产品质量不理想,滑片的耐磨性无法满足使用要求的问题。
为了解决上述问题,本发明采用的技术方案是:这种压缩机滑片的表面处理方法包括以下步骤:
(1)清除滑片表面的油污和杂质;
(2)用箱式电阻炉将清洗后的滑片加热至830~850℃,保温2~3h,然后迅速淬入温度为220~250℃的油中,保持1~2h,取出后,空冷至室温;
(3)随后进行低温回火,回火温度为150~160℃,保温1~2h,回火完成后空冷至室温;
(4)将滑片放入持续通入氨气的氮化炉中进行氮化处理,将炉温升至500~520℃,保温8~15 h,再将炉温升至520~540℃,保温20~45 h,随炉冷却至室温。
上述压缩机滑片的表面处理方法的技术方案中,更具体的技术方案还可以是:步骤(1)中用无水乙醇对滑片进行超声波清洗,清洗时间在3min以上。
进一步的,步骤(2)中的油为N32机械油。
进一步的,步骤(4)中氨气的分解率控制在25~32%。
进一步的,步骤(1)中的滑片为GCr15钢滑片。
由于采用了上述技术方案,本发明与现有技术相比具有如下有益效果:进行淬火加回火后具有较高的硬度、均匀的组织、良好的耐磨性、高的接触疲劳性能,能提高滑片的强度;渗氮参数的控制,避免渗氮出现裂纹,提高了渗氮硬度,表面硬度达到66HRC以上;处理前进行超声波清理,能保证硬度均匀。
