Product Details
 隆重向您推荐:消防气体顶压设备,气体顶压设备,气体顶压应急消防给水设备,北京专业生产厂家,价格低廉,型号齐全,包消防验收。

气体顶压设备组成:压力罐、稳压泵系统、汽瓶系统、汽泵、及控制系统。

稳压泵系统启动与运行:启动前首先向压力罐及系统里充水,充到一定程度后,启动稳压泵继续向系统打水,直至把稳压罐内的水位提高到设定的水位上限即M1时,稳压泵(两台一备一用)自动停止,这时如果压力处在系统设定的压力下限P2(P1为系统压力上限,P2为系统压力下限)以下时,汽泵自动向罐内补气直到压力达到设定的稳压系统压力上限P1时汽泵停止。这是一个稳压周期的完成,此时整个消防系统处在稳压状态。

当系统内泄漏压力下降到P2时,磁翻板液位计检测到罐内水位如果下降了,当水位降至设定的水位下限M2时,稳压泵系统自动启动,向系统内补水,补到系统设定的水位上限时M1,水泵停止。(如果在补水的过程中罐内压力过高,即高于设定的稳压系统压力上限,这时罐顶的电磁阀D2自动打开泄压,以保障水能补到设定的水位),如果此时系统压力低于系统设定的压力下限时,这时汽泵自动启动向罐内补气,一直补到系统设定的压力上限P1时汽泵停止,如此反复运行以保证稳压系统处在设定的水位(M1---M2)及压力(P1---P2)范围内,达到稳压的目的。

气瓶系统:气瓶组配有气瓶N只、各气瓶通过管路与一条DN25的管路相连,DN25管路与气压罐顶部相连,管路通断由电磁阀D1控制,气瓶内压力在(12MPa---15MPa)公斤,出口压力设定为系统的下限压力以下P4=0.42.平时气瓶系统并不工作一直处于休眠状态,有火灾发生时才投入工作。工作过程为当有火灾发生时,稳压系统压力急剧下降,当下降到P4时,气瓶组电磁阀D1打开,气瓶组的高压气体伴随气泵的高压气体迅速打到气压罐内,把气压罐里的水迅速打到管道内,以保证10分钟的应急消防水源供给。
