Description

水轮机密封装置
技术领域
本实用新型涉及一种水轮机密封装置。 
背景技术
目前冷却塔用水轮机在使用过程当中，由于设备本身结构紧凑、运转速快而传统密封结构单一等原因，经常引起水轮机齿轮油泄漏，进而造成齿轮、轴承的异常磨损，严重缩短了设备的使用寿命。 
实用新型内容
根据以上现有技术中的不足，本实用新型要解决的技术问题是：提供一种可以克服上述缺陷，能提高水轮机使用寿命，具有良好密封性的水轮机密封装置。 
本实用新型解决其技术问题所采用的技术方案是：一种水轮机密封装置，包括水轮机，其特征在于：还包括内套、外套，内套和外套均为弹性密封套，内套紧贴水轮机外壁，外套设置在内套外侧，内套和外套之间设置有阶梯式迷宫台阶。 
所述的阶梯式迷宫台阶内设置有弹性密封圈。 
水轮机外壁紧贴包覆有内套和外套，双重保证其密封性。而且内套与外套之间设置有阶梯式迷宫台阶，当发生介质泄漏时可增加介质泄漏路径，尽可能减少介质的泄漏量，同时阶梯式迷宫台阶内设置弹性密封圈，同样可增大介质泄漏路径和介质泄漏的摩擦力，从而减少介质损耗。 
本实用新型所具有的有益效果是：加工制造简单、维修方便、密封性能好、运行中稳定性与可靠性高。 
附图说明
图1是本实用新型结构示意图； 
图中：1、水轮机；2、内套；3、外套；4、阶梯式迷宫台阶；5、密封圈。 
具体实施方式
下面结合附图对本实用新型的实施例做进一步描述： 
如图1所示，一种水轮机密封装置，包括水轮机1，还包括内套2、外套3，内套2和外套3均为弹性密封套，内套2紧贴水轮机1外壁，外套3设置在内套2外侧，内套2和外套3之间设置有阶梯式迷宫台阶4，阶梯式迷宫台阶4内设置有弹性密封圈5。 
水轮机1外壁紧贴包覆有内套2和外套3，双重保证其密封性。而且内套2与外套3之间设置有阶梯式迷宫台阶4，当发生介质泄漏时可增加介质泄漏路径，尽可能减少介质的泄漏量，同时阶梯式迷宫台阶4内设置弹性密封圈5，同样可增大介质泄漏路径和介质泄漏的摩擦力，从而保证密封性，并减少介质损耗保证设备的使用寿命。
