汽(qi)液两(liang)相流液位自动疏水调节(jie)器构造及工作(zuo)原理:
汽(qi)液两相流(liu)液位自动疏水(shui)调节器构造:
汽(qi)液两(liang)(liang)相流液位自动(dong)疏水调(diao)节器由传(chuan)感器 (信(xin)号(hao)筒(tong)﹚和控制装置两(liang)(liang)部分(fen)构成。
传感(gan)器的作(zuo)用:发送容器内水位(wei)信号和变送调节用汽或液(ye)体量。

2.汽(qi)(qi)液(ye)(ye)两(liang)(liang)相(xiang)流(liu)(liu)自调(diao)节(jie)(jie)(jie)液(ye)(ye)位(wei)(wei)控(kong)(kong)(kong)制(zhi)器是(shi)基(ji)于(yu)流(liu)(liu)体力学理论和(he)控(kong)(kong)(kong)制(zhi)原理,利用(yong)汽(qi)(qi)液(ye)(ye)两(liang)(liang)相(xiang)流(liu)(liu)的(de)流(liu)(liu)动特遥(yao)(yao)遥(yao)(yao)设计的(de)一种全(quan)新概(gai)念的(de)液(ye)(ye)位(wei)(wei)控(kong)(kong)(kong)制(zhi)器,属自力式智能(neng)调(diao)节(jie)(jie)(jie),需消耗少(shao)量(liang)(liang)的(de)汽(qi)(qi)(约为(wei)排水(shui)量(liang)(liang)的(de)1-2%)作为(wei)执行(xing)(xing)遥(yao)(yao)遥(yao)(yao)的(de)驱动源。该液(ye)(ye)位(wei)(wei)控(kong)(kong)(kong)制(zhi)器由调(diao)节(jie)(jie)(jie)器疏水(shui)器和(he)信(xin)号管(guan)两(liang)(liang)部分组成。汽(qi)(qi)液(ye)(ye)两(liang)(liang)相(xiang)流(liu)(liu)自调(diao)节(jie)(jie)(jie)液(ye)(ye)位(wei)(wei)控(kong)(kong)(kong)制(zhi)器(疏水(shui)器)在火电厂加(jia)热(re)器上的(de)连接系统。信(xin)号管(guan)的(de)作用(yong)是(shi)发(fa)(fa)送(song)水(shui)位(wei)(wei)信(xin)号和(he)变送(song)调(diao)节(jie)(jie)(jie)用(yong)汽(qi)(qi);调(diao)节(jie)(jie)(jie)器的(de)作用(yong)是(shi)控(kong)(kong)(kong)制(zhi)出口水(shui)量(liang)(liang),相(xiang)当于(yu)自动调(diao)节(jie)(jie)(jie)系统中的(de)执行(xing)(xing)遥(yao)(yao)遥(yao)(yao)。其调(diao)节(jie)(jie)(jie)原理是(shi):当加(jia)热(re)器的(de)水(shui)位(wei)(wei)升高(gao)时,信(xin)号管(guan)内的(de)水(shui)位(wei)(wei)随之上升,导(dao)致(zhi)发(fa)(fa)送(song)的(de)调(diao)节(jie)(jie)(jie)汽(qi)(qi)量(liang)(liang)减少(shao),因(yin)而流(liu)(liu)过调(diao)节(jie)(jie)(jie)器中两(liang)(liang)相(xiang)流(liu)(liu)的(de)汽(qi)(qi)量(liang)(liang)减少(shao)、水(shui)量(liang)(liang)增加(jia),加(jia)热(re)器的(de)水(shui)位(wei)(wei)随之下降。反之亦然。由此实现了加(jia)热(re)器水(shui)位(wei)(wei)的(de)自动控(kong)(kong)(kong)制(zhi)。
