Description

一种涡轮增压器密封套
技术领域
本实用新型涉及一种涡轮增压器，具体地说，涉及一种涡轮增压器的密封套，属于机械技术领域。
背景技术
涡轮增压器在工作过程中，其密封机构是涡轮增压器保证正常工作的重要环节，防止轴承的润滑油进入增压器的气体流通部分，并阻止压气机的空气或涡端的燃气进入增压器的润滑油腔。
目前，密封机构中与背板配合的密封套上通常设置一道密封圈进行密封。使用这种密封套的涡轮增压器在脉冲增压时，涡轮前燃气瞬时压力会达到很高值，这样在涡轮端与压气机端压力平衡破坏情况下，密封效果差，容易发生漏油、漏气现象。当增压器漏油后，润滑油随压气机出口气流进入发动机会破坏发动机正常工作。
实用新型内容
本实用新型要解决的问题是针对以上问题，提供一种密封效果好、故障率低的一种涡轮增压器密封套。
为解决以上问题，本实用新型所采用的技术方案是：一种涡轮增压器密封套，包括密封套本体，其特征在于：所述密封套本体上设有两个密封槽，两个密封槽的轴向宽度分别为1.1+0.03 +0.035mm。
作为上述技术方案的进一步改进：
所述密封套本体的内径为φ4.1+0.005 +0.01mm。
所述密封套本体上设有甩油盘，甩油盘为圆盘形。
本实用新型采取以上技术方案，具有以下优点：与背板配合的密封套上设置两个密封槽，在密封槽内设置密封圈，均与背板油密封，增加了密封机构的密封性更好，能够有效降低发动机的故障率。
下面结合附图和实施例对本实用新型作进一步说明。
附图说明
附图为本实用新型实施例中密封套的结构示意图。
图中，
1-密封套本体，2-甩油盘，3-第一密封槽，4-第二密封槽。
具体实施方式
实施例，如图所示，一种涡轮增压器密封套，包括密封套本体1，密封套本体1上设有甩油盘2，甩油盘2为圆盘形，与背板配合的密封套本体1上设有两个密封槽，为第一密封槽3和第二密封槽4，第一密封槽3和第二密封槽4内分别安装有密封条，密封套本体1通过密封条与背板紧密配合并油密封，第一密封槽3和第二密封槽4的轴向宽度分别为1.1+0.03 0.035mm，密封套本体1的内径为φ4.1+0.005 +0.01mm。
