1、液體比重不同時(shí)，浮球的動(dòng)作位置將會(huì)有所變動(dòng)，一般SG比水小時(shí)，浮球浸在液體中部分將相對(duì)增多；2、產(chǎn)品參考比重以水（SG=1）所以使用時(shí)在選用浮球時(shí)須考慮液位的比重SG，一定大于浮球規(guī)格所標(biāo)示，否則，浮球開(kāi)關(guān)無(wú)法浮動(dòng)； 3、粘度高不會(huì)干涸的液體，一般應(yīng)選用外徑較大的浮球；4、使用磁鐵來(lái)感應(yīng)磁簧開(kāi)關(guān)，因此被測(cè)液位應(yīng)無(wú)鐵屑，否則會(huì)影響浮球?qū)﹂_(kāi)關(guān)的正確動(dòng)作。小型浮球液位開(kāi)關(guān)是一種、結(jié)構(gòu)簡(jiǎn)單，使用安裝方便的液位控制器。它沒(méi)有復(fù)雜的電路，不會(huì)受到干擾，使用磁簧開(kāi)關(guān)不需要提供電源即可工作并且接點(diǎn)壽命可達(dá)200萬(wàn)次。它設(shè)有復(fù)雜的電路，不會(huì)受到干擾，只要材質(zhì)選擇正確，任何性質(zhì)液體、壓力、溫度皆可使用。大連液位控制器報(bào)價(jià)液位開(kāi)關(guān)直裝式既可以頂裝也可以底裝。</p><div

style="text-indent:25px">浮球液位開(kāi)關(guān)的調(diào)試：浮球液位開(kāi)關(guān)在我們安裝前只需要重新標(biāo)定水位線。無(wú)法對(duì)開(kāi)關(guān)本身進(jìn)行調(diào)整的。這時(shí)用萬(wàn)用表測(cè)開(kāi)關(guān)狀態(tài)，在水線附近會(huì)隨水位高低通斷，這說(shuō)明沒(méi)問(wèn)題。只要保證安裝過(guò)程中與熱力設(shè)備的水位線一致就好了。比如SOR的液位開(kāi)關(guān)吧，一般在筒壁上都貼著水位線，我們把開(kāi)關(guān)泡在在水槽中，慢慢下沉，使水面逐漸靠近標(biāo)識(shí)線，靠近時(shí)會(huì)聽(tīng)到微動(dòng)開(kāi)關(guān)動(dòng)作的聲音。需要注意的是：高加液位開(kāi)關(guān)等的工作溫度高，里邊的水溫也高；高溫水的密度要小于室溫水密度。因而室溫水的動(dòng)作線比開(kāi)關(guān)標(biāo)識(shí)線要低些的。液位低報(bào)警接在常閉上(NC)，液位高接常開(kāi)(NO)。這類(lèi)開(kāi)關(guān)還是不難安裝的。液位開(kāi)關(guān)本身都會(huì)帶兩對(duì)以上的微動(dòng)開(kāi)關(guān)，分別輸出兩對(duì)常開(kāi)兩對(duì)常閉接點(diǎn)，在應(yīng)用時(shí)通常是"接通報(bào)警"。</p><p style="text-indent:25px">液位開(kāi)關(guān)的三大作用： 1、液位開(kāi)關(guān)有很多種類(lèi)，比如浮球液位開(kāi)關(guān)，是在密閉的非導(dǎo)磁性管內(nèi)安裝有一個(gè)或多個(gè)干簧管，然后將此管穿過(guò)一個(gè)或多個(gè)中空且內(nèi)部有環(huán)形磁鐵的浮球，液位的上升或下降會(huì)帶動(dòng)浮球一起移動(dòng)，從而使該非導(dǎo)磁性管內(nèi)的干簧管產(chǎn)生吸合或斷開(kāi)的動(dòng)作，并輸出一個(gè)開(kāi)關(guān)信號(hào)。2、液位開(kāi)關(guān)一般作為報(bào)警連鎖用，儲(chǔ)罐上用的比較多的是浮球液位開(kāi)關(guān)和外貼式超聲波液位開(kāi)關(guān)，一般我們儲(chǔ)罐上都只有一個(gè)液位計(jì)，但是重要的聯(lián)鎖我們往往要做2/2 或2/3的邏輯選擇程序，這個(gè)開(kāi)關(guān)就是液位計(jì)的補(bǔ)充，畢竟比新加一個(gè)液位計(jì)成本低。3、液位變送器可以放到罐頂，像雷達(dá)液位計(jì)、伺服液位計(jì)、超聲波液位計(jì)等你想放下了也不行，現(xiàn)在用的比較多的是罐頂?shù)囊何挥?jì)在罐下面加一個(gè)顯示表，便于觀察維護(hù)。電子式液位開(kāi)關(guān)安裝所需空間小，安裝工藝簡(jiǎn)單。</p><div

1、需要明白浮球液位開(kāi)關(guān)是怎樣來(lái)實(shí)現(xiàn)功能的，也就是它的工作原理。浮球液位開(kāi)關(guān)是由干簧管與浮球組成，通過(guò)浮球內(nèi)置磁鐵吸合干簧管觸點(diǎn)的閉合或者斷開(kāi)，從而輸出信號(hào)報(bào)警，而干簧管觸點(diǎn)的兩頭分別焊接一條線。2、要明白浮球液位開(kāi)關(guān)內(nèi)部結(jié)構(gòu)的接線圖，明白一個(gè)液位控制是怎么連接線路的，兩個(gè)甚至三個(gè)液位點(diǎn)，內(nèi)部的接線是怎樣的，這樣就完全可以明白怎么去接線了。浮球液位開(kāi)關(guān)接線注意事項(xiàng)：1.浮球液位開(kāi)關(guān)接線方法主要是干簧管式，而比如電纜式則是另外一回事，具體可以點(diǎn)下面鏈接去看看。2.需要另外提到一點(diǎn)就是浮球液位開(kāi)關(guān)是不可直接去控制水泵等產(chǎn)品，也就是說(shuō)不能夠直接連接220V電壓。音叉液壓開(kāi)關(guān)具有使用壽命長(zhǎng)、性能穩(wěn)定、安全可靠等優(yōu)點(diǎn)。大連液位控制器報(bào)價(jià)</p><p

1、根本型，根據(jù)浮力原理，浮子在丈量管內(nèi)隨液位的升降而上、下移動(dòng)，浮子內(nèi)的持久磁鋼通過(guò)耦合效果，驅(qū)動(dòng)紅、白色翻柱翻轉(zhuǎn)180°，液位上升時(shí)翻柱由白色轉(zhuǎn)為紅色，降低時(shí)由紅色轉(zhuǎn)為白色，然后完成液位指示。2、電遠(yuǎn)傳，在浮子液位計(jì)上裝置變送器，通過(guò)浮子上下移動(dòng)，經(jīng)磁耦合效果使導(dǎo)桿內(nèi)丈量元件順次動(dòng)作，取得電阻信號(hào)改變，轉(zhuǎn)換成0～10mA或4～20mA的標(biāo)準(zhǔn)信號(hào)輸出，與顯現(xiàn)外表或計(jì)算機(jī)連接，到達(dá)遠(yuǎn)傳意圖。 3、上下限開(kāi)關(guān)輸出，在液位計(jì)立管上由用戶(hù)設(shè)定上、下限方位裝置操控器，操控器內(nèi)帶有自保持效果的舌簧開(kāi)關(guān)，使用磁性浮子隨液位移動(dòng)使簧片開(kāi)關(guān)動(dòng)作時(shí)，完成報(bào)警或限位操控。大連液位控制器報(bào)價(jià)</p><p
