本文主要介紹計量泵的一些概念知識，希望對您計量泵購買時能對計量泵有更深一步的了解。巴特計量泵，真的很不錯的計量泵哦！巴特計量泵報價熱線：0371-67993077
怎么知道對于每臺計量泵都有哪些其他選項?
對于每臺計量泵和它的識別碼，在ProMinent® 產(chǎn)品目錄中都給出了詳細(xì)的解釋。通過查詢識別碼，對具體的計量泵可以選擇相應(yīng)的選項。
基本的附件包包括哪些?
附件包中包括：底閥，注射閥，2米吸液管和5米排液管線。
一個完整的計量泵泵頭都包括哪些部件?
一個完整的液力端包括以下部件：泵頭，隔膜，閥，背板和安裝螺栓。
底閥的主要用途是什么？
底閥本身有一定的重量可以保持吸液管線伸直并且使吸液管線垂直于化學(xué)藥桶。另外它也是一個逆止閥，保持化學(xué)藥液的正向流動。底閥還有助于改善泵的重復(fù)精度和正常吸液。底閥內(nèi)有濾網(wǎng)可以防止固體顆粒被吸入吸液管線，小的固體顆粒吸入可能會導(dǎo)致計量泵隔膜破損。底閥還包括連接件，用來連接吸液管。底閥應(yīng)當(dāng)垂直安裝，并且保持底閥離開儲藥桶底部一定距離。對于大多數(shù)靠自吸方式工作的計量泵底閥選擇是非常必要的。
注射閥的主要用途是什么？
注射閥被應(yīng)用于排液管線和注射點的連接。注射閥不能用作隔離設(shè)備或者用作防止虹吸的保護(hù)。在要求不是太高的場合中，注射閥可以產(chǎn)生0.5bar的背壓。
沖洗設(shè)備的主要用途是什么？
沖洗設(shè)備用來清洗計量泵泵頭和排液管線。主要應(yīng)用于計量的化學(xué)藥品易于凝固或者計量泵需要經(jīng)常處于閑置狀態(tài)的情況下。
什么是浮子開關(guān)，其主要作用是什么？
浮子開關(guān)是控制儲藥桶液位的非常關(guān)鍵的設(shè)備。當(dāng)液位降低時，浮子下沉，開關(guān)內(nèi)觸點閉合，此觸點可用于控制計量泵，例如停止計量泵1并啟動計量泵2，也可以用于接通報警/指示燈指示儲藥桶空。通過浮子的反向動作，浮子開關(guān)可以應(yīng)用于收集罐，指示收集罐已滿同時停止計量泵。
單級浮子開關(guān)和兩級浮子開關(guān)有什么不同?
當(dāng)開關(guān)動作時，單級浮子開關(guān)直接停止計量泵。對于兩級浮子開關(guān)，激活級時可以用來報警指示儲藥桶低液位。當(dāng)?shù)诙夐_關(guān)激活時，計量泵停止。
什么是多功能閥?
多功能閥是非常通用的產(chǎn)品，它可以產(chǎn)生恒定的背壓，確保重復(fù)計量精度。設(shè)備內(nèi)集成了防虹吸閥的功能，它可以防止化學(xué)藥品被吸入真空管線，防止水路中產(chǎn)生文丘里效應(yīng)或負(fù)輸送壓頭。 設(shè)備內(nèi)集成了泄壓閥功能，在系統(tǒng)管路阻塞時可以保護(hù)計量泵、管線和其他系統(tǒng)設(shè)備，防止過壓工作。多功能閥內(nèi)還集成有引液閥功能，可以釋放排液管線的壓力，幫助計量泵引液。多功能閥可以使排出液體安全地回流到儲藥桶中。
流量監(jiān)視器的主要功能是什么?
流量監(jiān)視利用接近開關(guān)，在每個流量脈沖動作時激活。計量泵將排液沖程和流量監(jiān)視到的脈沖數(shù)量進(jìn)行對比。 如果連續(xù)8個沖程或者設(shè)定的沖程數(shù)，泵不能檢測到相應(yīng)的脈沖信號，計量泵停止并發(fā)出故障指示。在吸液管線空、阻塞或泄漏，排液管線阻塞，隔膜破損等的情況下，流量監(jiān)視器都可以通過檢測不到脈沖信號而發(fā)出報警信號。 如果計量流量降低20%或低于設(shè)定的值，則比例流量監(jiān)視器就可以檢測到。
故障報警繼電器和步進(jìn)繼電器主要用途是什么？
報警繼電器在計量泵出現(xiàn)故障時觸點斷開(NC)或者閉合(NO)。
在計量泵出現(xiàn)故障時同步繼電器閉合，通常同步繼電器連接依附計量泵使其與主計量泵產(chǎn)生同樣的頻率。
脈沖阻尼器的主要用途是什么？
選擇合適尺寸的脈沖阻尼器可以減小90%或者更多的脈動，使產(chǎn)生接近于層流的流動。脈沖阻尼器減小被計量介質(zhì)的加速度并且降低壓頭損失。
緩沖器與脈沖阻尼器的功能有什么不同？
緩沖器可以減小管路的脈動，同時減小介質(zhì)的加速度并且降低水頭損失。緩沖器內(nèi)部液體和氣體沒有分離。緩沖器內(nèi)腔終會充滿液體，并且需要將液體排放掉。
什么是隔膜破裂監(jiān)視器，它是如何工作的？
在驅(qū)動端和泵頭之間的背板上有一漏液排出孔，一根導(dǎo)管連接漏液排出孔到一小圓柱筒內(nèi)。如果隔膜破裂，液體由漏液排出孔排到小圓柱筒內(nèi)。小圓柱筒內(nèi)有一浮子開關(guān)，只要筒內(nèi)有10ml的液體，浮子開關(guān)就可以被激活。開關(guān)觸點可以設(shè)置為常開或常閉。
