4月16日微型水泵能在不加引水的情況下，可以吸水，就表示這個水泵有自吸的功能?？沙槿∷?、液體(溶液)，適用于需要進行液體轉移、提升、清洗、噴灑、沖洗、灌溉等等多種場合。水泵的抽水管內是空氣的情況下，利用泵工作時形成的負壓（真空），在大氣壓的作用下將低于抽水口的水壓上來，再從水泵的排水端排出。這個過程前是不需要加“引水（引導用的水）”的。就是說具備這種自吸能力的微型水泵，就叫“微型自吸水泵”。簡稱：“微型吸泵”原理類似微型真空泵，鹽城計量泵密封生產廠家。 </p> <p> 微型水泵油脂粘度是發(fā)揮真空泵性能的重要因素之一，液體的粘度是液體流動阻力，或者說是液體的內摩擦力，鹽城計量泵密封生產廠家，鹽城計量泵密封生產廠家，因此粘度越大，各種運動部件所受的阻力就越大；但粘度太小，泵的密封性能變差，引起氣體泄漏，真空變劣。因此，各類微型水泵對潤滑油的選擇極為重要。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鹽城計量泵密封生產廠家" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247295161962890/6395142.jpg"></div><p> 機械密封處滲©水的第一種可能性是機封的動、靜環(huán)平面磨損。而造成機封的動、靜環(huán)平面磨損的原因有六個方面： </p> <p> 原因一、安裝過緊。觀察機械密封的動靜環(huán)平面，如有嚴重燒焦現象，平面發(fā)黑和很深的痕跡，密封橡膠變硬，失去彈性，這種現象是由于安裝過緊造成的。 </p> <p> 處理辦法：調整安裝高度，葉輪發(fā)裝后，用螺絲刀拔動彈簧，彈簧有較強的張力，松開后即復λ，有24MM的移動距離即可。 </p> <p> 原因二、安裝過松。觀察機封動、靜環(huán)平面，其表面有一層很薄的水垢，能夠擦去，表面基本無磨損，這是彈簧失去彈性及裝配不良造成，或電機軸向竄動造成。 </p> <p> 原因三、水質差含顆粒。由于水質差，含有小顆粒及介質中鹽酸鹽含量高，形成磨料磨損機封的平面或拉傷表面產生溝槽、環(huán)溝等現象。 </p> <p> 處理辦法：改進水壓或介質，更換機封。 </p> <p> 原因四、缺水運行造成干磨損壞。此現象多見于底閥式安裝形式進口處負壓，進水管有空氣，泵腔內有空氣，泵開機后，機封的磨擦高速運轉時產生高溫，無法得到冷卻，檢查機封，彈簧張力正常，摩擦面燒焦發(fā)黑，橡膠變硬開裂。處理辦法：排盡管道及泵腔內空氣，更換機械密封。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鹽城計量泵密封生產廠家" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247293380048828/7808572.jpg"></div><p> 為了充分發(fā)揮油封的功能，必須根據使用條件選定**合適的型式與材料。這里就主要的影響因素作一簡述。 </p> <p> <span style="font-size:12px;">軸的表面線速度：在同一直徑條件下，不同材料制造的油封，適應軸面旋轉線速度的能力不同，其關系如下圖所示。油封使用的線速度范圍一般小于15m/s, 滿意的潤滑和良好的散熱條件才是決定性因素。相應較低的數據，適用于更為苛刻的條件。 </span> </p> <p> <span style="font-size:12px;">溫度：由于旋轉軸表面與油封的密封唇部產生摩擦，所以密封唇口部的溫度高于油液中的溫度，一般油封工作時其唇緣的溫度高于工作介質溫度20~50℃。隨著轉速增高，壓力增加密封唇口處的溫度也隨之上升。另外，帶有防塵唇的油封，比無防塵唇的油封會出現高于20℃的過高溫度。當超過容許溫度時會縮短油封的工作壽命，造成密封唇過早長久性硬化，以及磨損加大。油封的工作溫度范圍與油封使用的材料有關：材料為丁晴橡膠（NBR）時為-40~120℃，亞力克橡膠（ACM）-30~180℃，氟橡膠（FPM）-25~300℃。</span> </p> <p> <span style="font-size:12px;">壓力：油封主要用于無壓或者在微壓的條件下使用，比較大工作壓力0.02～0.05Mpa。當工作壓力超過這個值時應選用耐壓型油封。</span> </p> <p> <br /> </p></p><br /><p>文章來源地址:
