style="text-indent:25px">擋板式流量開關(guān)如果不能動(dòng)作，該怎么辦呢？通常在空調(diào)系統(tǒng)中流量開關(guān)不動(dòng)作的原因是因?yàn)閾醢逅軟_力太小，其位移不足以使開關(guān)的常閉觸點(diǎn)閉合，尤其是大管徑低流速的情況下，要采用增加靶片面積進(jìn)行流量控制，如果管徑大而靶片相對(duì)較小則常會(huì)引起這種問題。此外對(duì)于使用的擋板式流量開關(guān)，必須注意安裝方向與水流方向要一致。如果是流量開關(guān)的靶片不能回，往往是靶片太寬或太長被卡住的緣故。如果安裝空隙不夠，即使當(dāng)時(shí)可以正常工作，長期使用中管道內(nèi)表面生銹或結(jié)垢造成通道變小，也有可能使靶片卡在管子內(nèi)不能有效動(dòng)作。一般要求靶片邊緣與管道內(nèi)壁要有不小于5 mm的距離。直通式流量開關(guān)價(jià)位選用劣質(zhì)的流量開關(guān)，會(huì)有重大的安全隱患,因此要選用好的流量開關(guān)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">流量開關(guān)在選型時(shí)應(yīng)該注意：1、供電電壓多大，是直流還是交流，一般直流為24V，交流220V。2、功耗為多少。3、輸出方式，有常開和常閉。4、觸點(diǎn)容量，一般流量開關(guān)通過設(shè)定流量，即可顯示流量是否達(dá)到設(shè)定值。流量開關(guān)需使用規(guī)定的電源電壓，使用規(guī)定以外的電壓，會(huì)引起開關(guān)誤動(dòng)作、損壞、觸電和火災(zāi)等。流量開關(guān)不要使用超過開關(guān)較大負(fù)荷的負(fù)載。請(qǐng)不要使用會(huì)產(chǎn)生浪涌電壓的負(fù)載。開關(guān)的輸出部分，因?yàn)闆]有浪涌保護(hù)裝置，所以反向電壓會(huì)使開關(guān)損壞。當(dāng)直接驅(qū)動(dòng)繼電器、電磁閥等會(huì)產(chǎn)生浪涌電壓的負(fù)載時(shí)，要使用內(nèi)置浪涌吸收元件型號(hào)的產(chǎn)品。</p><p style="text-indent:25px">水流量開關(guān)的調(diào)試：1，水流量開關(guān)是工廠附近的較小流量值調(diào)整，在使用時(shí)不能設(shè)置比工廠設(shè)定位置時(shí)，這將導(dǎo)致開關(guān)不能返回到“不流動(dòng)”位置低。2.如果需要增加流量值，順時(shí)針轉(zhuǎn)動(dòng)調(diào)整螺釘。如果您想在增加出廠設(shè)置值后降低流量值，請(qǐng)轉(zhuǎn)動(dòng)可逆時(shí)鐘的調(diào)整螺釘。3、調(diào)整結(jié)束后，流量開關(guān)的設(shè)定值應(yīng)檢查不小于工廠設(shè)定值。通過多次按主杠桿，檢查開關(guān)是否有“點(diǎn)擊”的聲音當(dāng)主杠桿返回，一旦發(fā)現(xiàn)沒有。時(shí)鐘應(yīng)旋轉(zhuǎn)調(diào) 節(jié)螺絲，直到杠桿以“點(diǎn)擊”的聲音返回。4.密封漆的定型螺絲不可調(diào)。一旦改變，就會(huì)破壞流量開關(guān)的控制，或?qū)е抡{(diào)節(jié)失效。5，流量調(diào)節(jié)器太高，以驅(qū)動(dòng)在低流量的片流，所述開關(guān)不能**作。流量調(diào)節(jié)過低，過于敏感開關(guān)故障。機(jī)械形式的流量開關(guān)的價(jià)格低。</p><div

style="text-indent:25px">選擇流量開關(guān)的要素有：1.儀表周圍有無大功率設(shè)備；2.防護(hù)等級(jí)3.介質(zhì)溫度與壓力以及介質(zhì)較小流量，常用流量，較大流量，4.殼體材質(zhì)，5.準(zhǔn)確度；6.儀表口徑，7.儀表安裝環(huán)境溫度；8.開關(guān)設(shè)定刻度與連線方式，9.儀表周圍有無大功率設(shè)備； 10.儀表電源線走向問題。水流開關(guān)的流量效果由精度和安裝要求來決定。選擇合適的流量開關(guān)，除了根據(jù)自己需求功能選型之外，還應(yīng)該根據(jù)流體工況特性、安裝要求、環(huán)境條件、經(jīng)濟(jì)性以及用戶提供的參數(shù)等做出合理的選擇。壓差式流量開關(guān)即使水系統(tǒng)中有空氣也不會(huì)產(chǎn)生漂浮的情況。固體流量控制器哪家好</p><p

style="text-indent:25px">擋板式流量開關(guān)的安裝須知：1.安裝時(shí)管道中的水流方向一定要和水流開關(guān)上塑料殼體上的箭頭方向一致，否則水流開關(guān)無法工作。2.切勿用手及工具扳動(dòng)黑色儀表外殼，造成內(nèi)部元器件損傷，水流開關(guān)將無法進(jìn)行工作。3.安裝位置一般安裝在水泵出水口到設(shè)備出水口的這段管路中，不要安裝在水泵的吸入口的管路上，這樣容易致使水泵無法正常吸水，水流開關(guān)也無法打開。4.允許將擋板式水流開關(guān)進(jìn)行水平或垂直安裝，但塑料接線盒不能在下，即不能倒置。5.擋板式流量開關(guān)一定要安裝到一段直管段上，其兩邊要滿足有5倍管徑的直管段。固體流量控制器哪家好</p><p
