style="text-indent:25px">壓差式流量開(kāi)關(guān)的設(shè)計(jì)原理是根據(jù)HVAC設(shè)備的阻力和流量的曲線(xiàn)來(lái)設(shè)計(jì)的。往往根據(jù)HVAC設(shè)備的原理可以看到壓差式流量開(kāi)關(guān)的工作原理。HVAC設(shè)備的換熱器有其阻力與流量的性能曲線(xiàn)，通過(guò)檢測(cè)其兩端的進(jìn)出水壓差，并與該裝置的預(yù)先設(shè)定值進(jìn)行比較，就可以準(zhǔn)確控制流量。流量開(kāi)關(guān)有多種，分別是，壓差式和靶式流量開(kāi)關(guān)，然而兩者相比，壓差式流量開(kāi)關(guān)是一種精確的流量控制方式，它具有準(zhǔn)確的流量控制值。它直接安裝在機(jī)組內(nèi)，避免用戶(hù)安裝不正確的情況出現(xiàn)。如果在機(jī)組內(nèi)安裝從壓差開(kāi)關(guān)連接兩根銅管至換熱器的進(jìn)出口，測(cè)量其進(jìn)出口的壓差，即反映出流量。而用戶(hù)現(xiàn)場(chǎng)不需要安裝和接線(xiàn)，也就避免了靶式水流開(kāi)關(guān)的安裝不準(zhǔn)確導(dǎo)致機(jī)組故障的隱患。</p><p style="text-indent:25px">選用劣質(zhì)的流量開(kāi)關(guān)，會(huì)有重大的安全隱患，一旦出現(xiàn)事故，會(huì)被追責(zé)到底。由于消防行業(yè)的重要性，不但要求流量開(kāi)關(guān)在安裝調(diào)試時(shí)能達(dá)到要求，而且要求流量開(kāi)關(guān)能夠長(zhǎng)期穩(wěn)定運(yùn)行，不能在關(guān)鍵時(shí)刻掉鏈子。如果用戶(hù)貪便宜，為了敷衍消防驗(yàn)收人員，選擇劣質(zhì)的流量開(kāi)關(guān)，可能會(huì)在時(shí)間之后，開(kāi)關(guān)不能發(fā)出信號(hào)，一旦發(fā)生消防事故，將會(huì)用于流量開(kāi)關(guān)不能及時(shí)啟泵，造成重大的安全責(zé)任事故。流量開(kāi)關(guān)要注意開(kāi)關(guān)的外部壓降。在劃定規(guī)矩電壓以下使用開(kāi)關(guān)時(shí)，會(huì)呈現(xiàn)，縱然流量開(kāi)關(guān)任務(wù)畸形，但負(fù)載不行動(dòng)的景象。流量開(kāi)關(guān)的保護(hù)值在工廠已經(jīng)標(biāo)定好不需再做調(diào)整。</p><div

style="text-indent:25px">水流量開(kāi)關(guān)的真正作用是：1.檢測(cè)管路中液體是否流動(dòng)和流動(dòng)的量（流量，也就是液體流動(dòng)壓力）是否達(dá)到要求，同時(shí)靠開(kāi)關(guān)電接點(diǎn)輸出（提供）一個(gè)信號(hào)的通斷的狀態(tài)。2.設(shè)備系統(tǒng)靠檢測(cè)有無(wú)信號(hào)或控制電流從此開(kāi)關(guān)上通過(guò)（水流開(kāi)關(guān)電接點(diǎn)的通、斷狀態(tài)）來(lái)判斷管路系統(tǒng)的工作狀況，給出相應(yīng)的控制或運(yùn)行方式或措施。壓差式流量開(kāi)關(guān)在未出廠前可直接由工廠安裝在機(jī)組內(nèi)，并且現(xiàn)場(chǎng)安裝的部件不但不會(huì)影響它流量控制準(zhǔn)確性，對(duì)主水管管徑無(wú)任何要求，可以給我們帶來(lái)的很多便利和成功率。壓差式流量開(kāi)關(guān)壓差開(kāi)關(guān)動(dòng)作和復(fù)位有明確的流量值。工業(yè)流量開(kāi)關(guān)哪里買(mǎi)</p><p

style="text-indent:25px">靶式水流開(kāi)關(guān)的靶流片在正常使用時(shí)長(zhǎng)期受水流壓迫處于彎曲變形狀態(tài)，易疲勞破壞，尤其在流速超過(guò)3m/s以上時(shí)其壽命將縮短。如果每個(gè)模塊都需要流量信號(hào)，就更不適宜安裝靶式流量開(kāi)關(guān)。目前各個(gè)模塊機(jī)廠家的模塊機(jī)的換熱器就近接模塊機(jī)組的主水管，不可能提供安裝靶流開(kāi)關(guān)所需要的前后段較小的直管距離，讓一些廠家不得不放棄每個(gè)模塊需要一個(gè)水流信號(hào)這一理想的水流保護(hù)方法。量開(kāi)關(guān)殼體內(nèi)部的流體通道上裝有一個(gè)內(nèi)部裝有永久磁鐵的活塞。當(dāng)活塞被液流所引起的壓力差推動(dòng)時(shí)，磁性活塞便會(huì)使設(shè)備內(nèi)部的密封簧片開(kāi)關(guān)動(dòng)作，活塞的直徑?jīng)Q定了啟動(dòng)流量。兩個(gè)傳感元件之間的溫差與過(guò)程流速及過(guò)程介質(zhì)的性質(zhì)有關(guān)。兩個(gè)傳感元件之間的溫差在無(wú)流量狀態(tài)下較大，但隨著流量的增加，被加熱的傳感元件冷卻，溫差減小。流體流速直接影響熱擴(kuò)散的程度。高溫流量控制器哪里買(mǎi)</p><p
