Abstract

一种小型水轮发电机转子顶起充油装置，其特点是：它包括油箱，在油箱上置有伸入油箱油中的抽油缸，抽油缸的结构是，包括在油箱内置的缸体，缸体上支座固定在油箱的上盖上，在缸体上支座设置的出油口上连接有逆止阀，在缸体的下端设有吸油口，在缸体内设有抽油活塞，在抽油活塞上置有单向阀，抽油活塞的活塞杆上端与动力杆铰接，动力杆的前端与缸体上支座的支臂铰接。抽油缸的抽油活塞靠动力杆手动操作，往复上下运动将油箱内的油由缸体的吸油口通过单向阀吸入缸体上腔，再通过缸体上支座出油口的逆止阀压入水轮发电机组的吸油口而将水轮发电机转子顶起，并且实现支撑转子的推力轴承的油润滑，具有结构简单，使用简便，手动操作，无需电源等优点。

Description

小型水轮发电机转子顶起充油装置
技术领域
本实用新型是一种用于小型水轮发电机转子顶起充油装置。 
背景技术
现有小型水电站一般是各自独立供电系统，电站主要设备的水轮发电机经常需要停机，长时间停机再开机前需要给水轮发电机组支撑转子的推力轴承注入润滑油，水轮发电机组支撑转子的推力轴承注入润滑油需要首先将水轮发电机组的转子顶起来。通常需要通过现有技术的电动液压泵产生的液压力将水轮发电机组的转子顶起来，再为推力轴承注入润滑油。由于独立供电的小型水电站在水轮发电机组停机的情况下，通常当停电或没有备用适合电动液压泵工作所需要的电源时，不能实现将水轮发电机组的转子顶起来而对其支撑推力轴承注入润滑油，在少润滑油的情况下，水轮发电机组强行开机将会降低其使用寿命或损毁。 
发明内容
本实用新型所要解决的技术问题是，提供一种结构简单，使用简便，手动操作，无需电源供电的小型水轮发电机转子顶起充油装置。 
解决其技术问题采用的技术方案是，一种小型水轮发电机转子顶起充油装置，其特征是：它包括油箱，在油箱上置有伸入油箱油中的抽油缸，所述抽油缸的结构是，包括在油箱内置的缸体，缸体上支座固定在油箱的上盖上，在缸体上支座设置的出油口上连接有逆止阀，在缸体的下端设有吸油口，在缸体内设有抽油活塞，在抽油活塞上置有单向阀，抽油活塞的活塞杆上端与动力杆铰接，动力杆的前端与缸体上支座的支臂铰接。 
本实用新型的小型水轮发电机转子顶起充油装置，由于在油箱上置有伸入油箱油中的抽油缸，抽油缸的抽油活塞靠动力杆手动操作，往复上下运动将油箱内的油由缸体的吸油口通过单向阀吸入缸体上腔，再通过缸体上支座出油口的逆止阀压入水轮发电机组的吸油口而将水轮发电机转子顶起，并且实现支撑转子的推力轴承的油润滑,具有结构简单，使用简便，手动操作，无需电源等优点。 
附图说明
图1 是小型水轮发电机转子顶起充油装置结构示意图；
图2 是图1中A-A剖视示意图。
图中：1逆止阀，2缸体，3吸油口，4油箱，5缸体上支座，6支臂，7单向阀，8动力杆，9抽油活塞。
具体实施方式
下面利用实施例对本实用新型作进一步说明。 
参照图1和图2，本实用新型的小型水轮发电机转子顶起充油装置具有油箱4，在油箱4上置有伸入油箱4油中的抽油缸，所述抽油缸的结构是，包括在油箱4内置的缸体2，缸体上支座5固定在油箱4的上盖上，在缸体上支座5设置的出油口上连接有逆止阀1，在缸体2的下端设有吸油口3，在缸体2内设有抽油活塞9，在抽油活塞9上置有单向阀7，抽油活塞9的活塞杆上端与动力杆8铰接，动力杆8的前端与缸体上支座5的支臂6铰接。抽油缸的缸体2、缸体上支座5和支臂6为一体结构。逆止阀1和单向阀7均采用市售单向阀。利用逆止阀1和单向阀7具有正向通油，反向截油的特点而实现反向液压自锁的目的，通过逆止阀1和单向阀7向水轮发电机组的吸油口正向供油而使水轮发电机转子顶起，为支撑转子的推力轴承提供油润滑。
