<p> 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。 </p> <p> <br /> </p> <p>

雙側(cè)進水式泵：又叫雙吸泵，即葉輪兩側(cè)都有一個進水口。它的流量比單吸式泵大一倍，可以近似看作是二個單吸泵葉輪背靠背地放在了一起。 </p> <p> 按泵殼結(jié)合來分類 </p> <p> 水平中開式泵：即在通過軸心線的水平面上開有結(jié)合縫。 </p> <p> 垂直結(jié)合面泵：即結(jié)合面與軸心線相垂直。 </p> <p> 按泵軸位置來分類 </p> <p> 臥式泵：泵軸位于水平位置。 </p> <p> 立式泵：泵軸位于垂直位置。 </p> <p> 按葉輪出方式分類 </p> <p> 蝸殼泵：水從葉輪出來后，直接進入具有螺旋線形狀的泵殼。 </p> <p> 導(dǎo)葉泵：水從葉輪出來后，進入它外面設(shè)置的導(dǎo)葉，之后進入下一級或流入出口管。 </p><p> 04泵排液后中斷故障分析：吸入管路漏氣；灌泵時吸入側(cè)氣體未排盡；吸入側(cè)突然被異物堵住，或吸入口濾器堵塞；吸入管脫水，大量氣體吸入解決方法：檢查吸入側(cè)連接處及填料函的密封情況；重新灌泵；停泵，清洗濾芯，疏通吸入管路；檢查吸入管路是否破裂。并聯(lián)進口管線上的閥門是否打開（不常用的管線）。05流量不足故障分析：系統(tǒng)凈揚程增加；阻力損失增加；口環(huán)及葉輪磨損過大；其它地方漏液；泵葉輪堵塞、磨損、腐蝕。解決方法：檢查液位高度和系統(tǒng)壓力；檢察管路及止回閥等有無故障；更換口環(huán)及葉輪；檢查軸封等地方；清洗、檢查、調(diào)換。06揚程不夠故障分析：葉輪裝反（雙吸泵）；液體密度、黏度與設(shè)計條件不符；操作流量太大。解決方法：檢查葉輪；檢查有關(guān)物理性質(zhì)；調(diào)解閥門、減少硫量。07運行超負(fù)荷故障分析：動機質(zhì)量差，定轉(zhuǎn)子摩擦；葉輪與承磨環(huán)、葉輪與泵殼有摩擦；液體密度增加；填料壓得太緊或干摩擦；軸承損壞；轉(zhuǎn)速過高；泵軸彎曲；軸向力平衡裝置失效；聯(lián)軸器對中不良或軸向間隙太小；輸送液體黏度過高或密度過大。解決方法：檢查更換電動機；檢查泵內(nèi)零件并加以修理；檢查密度；放松填料、檢查水封管；檢查與更換軸承；檢察原動機轉(zhuǎn)速與電源；校正泵軸。靖江市瑞鑫泵業(yè)有限公司——歡迎您的來電詳詢。</p><div

二、安裝高度Hg計算允許吸上真空高度Hs是指泵入口處壓力p1可允許達到的zui大真空度，而實際的允許吸上真空高度Hs值并不是根據(jù)式計算的值，而是由泵制造廠家實驗測定的值，此值附于泵樣本中供用戶查用。位應(yīng)注意的是泵樣本中給出的Hs值是用清水為工作介質(zhì)，操作條件為20℃及及壓力為×105Pa時的值，當(dāng)操作條件及工作介質(zhì)不同時，需進行換算。1、輸送清水，但操作條件與實驗條件不同，可依下式換算Hs1=Hs+Ha－－Hυ－2輸送其它液體當(dāng)被輸送液體及反派人物條件均與實驗條件不同時，需進行兩步換算：*步依上式將由泵樣本中查出的Hs1；第二步依下式將Hs1換算成H?s2、汽蝕余量Δh對于油泵型號，計算安裝高度時用汽蝕余量Δh來計算，即泵允許吸液體的真空度，亦即泵允許的安裝高度，單位用米。用汽蝕余量Δh由油泵樣本中查取，其值也用20℃清水測定。若輸送其它液體，亦需進行校正，詳查有關(guān)書籍。吸程=標(biāo)準(zhǔn)大氣壓（）-汽蝕余量-安全量（）標(biāo)準(zhǔn)大氣壓能壓管路真空高度。例如：某泵必需汽蝕余量為，求吸程Δh？解：Δh=從安全角度考慮，泵的實際安裝高度值應(yīng)小于計算值。當(dāng)計算之Hg為負(fù)值時，說明泵的吸入口位置應(yīng)在貯槽液面之下。例2-3某離心泵從樣本上查得允許吸上真空高度Hs=。靖江市瑞鑫泵業(yè)有限公司——給您質(zhì)量服務(wù)。無錫耐磨離心泵類型</p><p
