Description

带防汽蚀装置的液环式真空泵
技术领域
本实用新型涉及液环式真空泵,具体讲是一种带防汽蚀装置的液环式真空泵。
背景技术
我们知道,现有的液环式真空泵,是在泵体上方设有汽水分离器,这种液环式真空泵,在极限压力状态下工作或者泵内工作介质温度高时,导致泵内产生汽蚀,运行振动大、噪音大,长时间运行容易损坏液环式真空泵。
发明内容
本实用新型解决的技术问题是,解决在极限压力状态下工作或者泵内工作介质温度高时,导致泵内产生汽蚀,运行振动大、噪音大,长时间运行容易损坏液环式真空泵的问题,提供一种在极限压力状态下工作或者泵内工作介质温度高,导致泵内产生汽蚀时,可以消除泵内汽蚀,有效防止泵体损坏,保持安全正常运转的带防汽蚀装置的液环式真空泵。
本实用新型的技术方案是:泵体上方设有汽水分离器,主要结构特点是,泵体左侧经左气体分配盘设有左通气管,泵体右侧经右气体分配盘设有右通气管,左通气管和右通气管上设有通气连通管,通气连通管与汽水分离器相连通,左通气管和右通气管上分别设有左通气开关和右通气开关。
本实用新型的有益效果是,由于泵体左侧设有左通气管,泵体右侧设有右通气管,左通气管和右通气管上设有通气连通管,通气连通管与汽水分离器相连通,在极限压力状态下工作或者泵内工作介质温度高,导致泵内产生汽蚀时,可以消除泵内汽蚀,有效防止泵体损坏,能够保持安全正常运转。本实用新型适用于液环式真空泵。
附图说明
附图是本实用新型的一种结构示意图。
具体实施方式
如图所示的带防汽蚀装置的液环式真空泵,泵体3上方设有汽水分离器4,泵体3左侧经左气体分配盘设有左通气管1,泵体3右侧经右气体分配盘设有右通气管7,左通气管1和右通气管7上设有通气连通管6,通气连通管6与汽水分离器4相连通,左通气管1和右通气管7上分别设有左通气开关2和右通气开关5,当液环式真空泵在极限压力状态下工作或者泵内工作介质温度高,导致泵内产生汽蚀时,逐渐打开左通气开关2和右通气开关5,气体从汽水分离器4经通气连通管6,经左通气管1和右通气管7进入泵体3内,可以消除泵内汽蚀,有效防止泵体损坏,能够保持安全正常运转。
