計(jì)量泵以其超好的優(yōu)越性，在各行業(yè)中得到廣泛的應(yīng)用，以下介紹各類計(jì)量泵基礎(chǔ)知識(shí)問答，新手必看，老手可略過。巴特計(jì)量泵供應(yīng)者，做全球做好的泵。
1、計(jì)量泵基本的附件包括哪些?
答：附件中包括：底閥，注射閥，2米吸液管和5米排液管線。
2、一個(gè)完整的計(jì)量泵泵頭都包括哪些部件?
答：一個(gè)完整的液力端包括以下部件：泵頭，隔膜，閥，背板和安裝螺栓。
3、底閥的主要用途是什么？
答：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(gè)逆止閥，保持化學(xué)藥液的正向流動(dòng)。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(huì)導(dǎo)致計(jì)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(chǔ)藥桶底部一定距離。對于大多數(shù)靠自吸方式工作的計(jì)量泵底閥選擇是非常必要的。
4、注射閥的主要用途是什么？
答：注射閥被應(yīng)用于排液管線和注射點(diǎn)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。
5、沖洗設(shè)備的主要用途是什么？
答：沖洗設(shè)備用來清洗計(jì)量泵泵頭和排液管線。主要應(yīng)用于計(jì)量的化學(xué)藥品易于凝固或者計(jì)量泵需要經(jīng)常處于閑置狀態(tài)的情況下。
6、什么是浮子開關(guān)，其主要作用是什么？
答：浮子開關(guān)是控制儲(chǔ)藥桶液位的非常關(guān)鍵的設(shè)備。當(dāng)液位降低時(shí)，浮子下沉，開關(guān)內(nèi)觸點(diǎn)閉合，此觸點(diǎn)可用于控制計(jì)量泵，例如停止計(jì)量泵1并啟動(dòng)計(jì)量泵2，也可以用于接通報(bào)警/指示燈指示儲(chǔ)藥桶空。通過浮子的反向動(dòng)作，浮子開關(guān)可以應(yīng)用于收集罐，指示收集罐已滿同時(shí)停止計(jì)量泵。
7、單級浮子開關(guān)和兩級浮子開關(guān)有什么不同?
答：當(dāng)開關(guān)動(dòng)作時(shí)，單級浮子開關(guān)直接停止計(jì)量泵。對于兩級浮子開關(guān)，激活級時(shí)可以用來報(bào)警指示儲(chǔ)藥桶低液位。當(dāng)?shù)诙夐_關(guān)激活時(shí)，計(jì)量泵停止。
