Abstract

本实用新型涉及制冷领域,是一种用于单机双级 制冷压缩机的回液回油筒。其结构特征是在密封筒 体上部设有低压回液口、低压回油口、控制台回油口, 下部设有出油口,各油口均设有阀门,其中低压回液 口分别设有低压回液阀和高压进气阀。本实用新型 结构合理,具有回液和回油功能,特别适用于超低温 压缩机上使用。

Description

本实用新型涉及制冷领域,特别是一种用于单机双级制冷压缩机的回液回油装置。
现有的单机双级制冷压缩机为防止液击事故,是在系统回气管路上装设热交换器,回气中所挟带的液体经热交换后蒸发成气体,并回压缩机低压腔;为适应超低工况,压缩机体中的低压级气腔与曲轴箱隔开,在低压级吸气腔上设一回油口,回油口与回油筒相通,回油筒所聚集的回油需经过油包上油分配阀返回曲轴箱内,整过回油过程较复杂。
本实用新型的目的是设计一种回液和回油合二为一的回液回油筒。
本实用新型的任务是这样完成的,在密封筒体的上部设有低压回液口、低压回油口、控制台回油口、下部设有出油口、各油口均设有阀门,其中低压回液口分别设有低压回液阀和高压进气阀,各油口经阀门后与压缩机的相应部件相连通,设备运行时,关闭高压进气阀和出油口阀,打开其它阀门,系统的低压回气管路在回气时所挟带的液体,先回到筒内,经自然蒸发成气体,经低压回油口回到低压级吸气腔内,低压级吸气腔内的余油经低压回油口进入筒内,控制台能量调节阀的余油经控制台回油口进入筒内,回油时,只要关闭低压回液阀,低压回油口和控制台回油口上的阀门,打开出油口阀和高压进气阀,让高压气体进入筒内,将回油从筒体下部经出油口压回曲轴箱内,达到油的循环使用。
本实用新型结构合理简单,同时具有回液和回油功能,可广泛用于超低温单机双级制冷压缩机上使用。
下面结合图例对本实用新型做进一步描述。
图1、回液回油筒示意图
参照图1密封筒体1上部设有低压回液口2,低压回液口2分别设有低压回液阀3和高压进气阀4,并与压缩机的低压回气管路和高压气管路相连通,低压回油口5和控制台回油口6均开设在筒体1的上部,分别配有阀7,并与压缩机的低压级吸气腔和控制台能量调节阀相连通,出油口8开设在筒体1下部,内接连通管9直至筒体底部,外接阀7后与压缩机的曲轴箱连通。
