新聞山東THOMAS CENTRI 776 SEK INOX脫水機報價
任何一臺待修泵、修好的泵或一臺新泵均應(yīng)進行試抽測，檢查有否故障、故障表現(xiàn)的形式和部位、所能達到的極限真空度和經(jīng)歷的時間，有條件的還要進行抽氣速率的鑒定。試抽測的具體方法、步驟如下:1.清擦干凈該泵所有部分，去除油污、臟物。取下皮帶，用倒順開關(guān)試馬達正反轉(zhuǎn)，使其轉(zhuǎn)向與泵輪所標(biāo)箭頭方向一致。若泵輪無標(biāo)記，可用手掌泵進氣口，以另一手盤動皮帶輪，感到向內(nèi)有吸力時皮帶輪的轉(zhuǎn)動方向即為正確方向，作好標(biāo)記。然后上好皮帶.開泵前在泵進氣口接入測試裝置。

在所有的齒輪泵中屬于品質(zhì)比較并且有一定特殊的應(yīng)用范圍。但是不銹鋼泵在工作的時候也會出現(xiàn)一些意想不到的故障，比如停機。我們就有必要來分析一下停機的主要原因，這樣就可以避免以后造成不必要的機器損害。停機主要是由機械密封的失效造成的。失效的表現(xiàn)大都是泄漏，泄漏原因有以下幾種：1.齒輪泵動靜環(huán)密封面的泄漏，原因主要有：端面平面度，粗糙度未達到要求，或表面有劃傷；端面間有顆粒物質(zhì)，造成兩端面不能同樣運行；安裝不到位，方式不正確。、在凝結(jié)水回收系統(tǒng)中，若利用工作背壓回收凝結(jié)水時，應(yīng)選用背壓率較高的蒸汽疏水閥（如機械型蒸汽疏水閥）；當(dāng)用汽設(shè)備內(nèi)要求不得積存凝結(jié)水時，應(yīng)選用能連續(xù)排出飽和凝結(jié)水的蒸汽疏水閥（如浮球式蒸汽疏水閥）；在凝結(jié)水回收系統(tǒng)中，用汽設(shè)備既要求排出飽和凝結(jié)水，又要求及時排除不凝結(jié)性氣體時，應(yīng)采用能排飽和水的蒸汽疏水閥與排氣裝置并聯(lián)的疏水裝置或采用同時具有排水、排氣兩種功能的蒸汽疏水閥（如熱靜力型蒸汽疏水閥）；當(dāng)用汽設(shè)備工作壓力經(jīng)常波動時，應(yīng)選用不需要調(diào)整工作壓力的蒸汽疏水閥。、蒸汽疏水閥的公稱壓力及工作溫度應(yīng)大于或等于蒸汽管道及用汽設(shè)備的高工作壓力及高工作溫度。、一個蒸汽疏水閥的排水能力不能滿足要求時，可并聯(lián)安裝幾個蒸汽疏水閥。、為便于檢修可設(shè)旁通管及旁通閥。蒸汽疏水閥的使用說明：1）、裝前清洗管路設(shè)備，除去雜質(zhì)，以免堵塞。、蒸汽疏水閥必須安裝在用汽設(shè)備低點下方和易排水、易于檢修的地方，并盡可能集中排列，以便于管理，連接應(yīng)牢固緊密。、安裝時，注意閥體上箭頭方向與管路內(nèi)介質(zhì)流動方向應(yīng)一致。補償環(huán)密封圈泄漏，原因主要有：壓蓋變形，預(yù)緊力不均勻；安裝不正確；密封圈質(zhì)量不符合標(biāo)準(zhǔn)；密封圈選型不對。齒輪泵停止運轉(zhuǎn)后的要求：1.輸送易結(jié)晶，易凝固，易沉淀等介質(zhì)的泵，停泵后應(yīng)防止堵塞，并及時用清水或其他介質(zhì)沖洗泵和管道。高溫齒輪泵停車應(yīng)按設(shè)備技術(shù)文件的規(guī)定執(zhí)行，停車后應(yīng)每偏2一3min盤車半圈，直到泵體溫度降至5℃為止。離心油泵停止運轉(zhuǎn)后應(yīng)關(guān)閉泵的人口閥門，待泵冷卻后再依次關(guān)閉附屬系統(tǒng)的閥門。
