眾所周知，對于各種真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)性(xing)能(neng)，都(dou)有規(gui)定的(de)(de)(de)(de)(de)(de)測試方(fang)法來測試該性(xing)能(neng)的(de)(de)(de)(de)(de)(de)性(xing)能(neng)，主要(yao)性(xing)能(neng)是(shi)極限(xian)壓(ya)(ya)(ya)力，流(liu)(liu)量(liang)(liang)和抽(chou)(chou)速(su)。這(zhe)次，小(xiao)編(bian)打算(suan)討論螺桿真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流(liu)(liu)量(liang)(liang)，例如如何控制(zhi)(zhi)其流(liu)(liu)量(liang)(liang)，流(liu)(liu)量(liang)(liang)不(bu)(bu)足的(de)(de)(de)(de)(de)(de)原因(yin)以(yi)及如何消(xiao)除(chu)此問(wen)題(ti)。相信許多用(yong)(yong)(yong)戶對這(zhe)些(xie)問(wen)題(ti)感到困(kun)惑，不(bu)(bu)用(yong)(yong)(yong)擔(dan)心(xin)，請(qing)跟隨螺桿真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)廠(chang)家(jia)進行(xing)了(le)解(jie)。 首先，讓我們簡單介紹一下真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)主要(yao)性(xing)能(neng)的(de)(de)(de)(de)(de)(de)概念。 1.極限(xian)壓(ya)(ya)(ya)力。真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)與檢測容(rong)器相連，放(fang)置待測氣(qi)(qi)體后，連續長(chang)時(shi)(shi)(shi)間抽(chou)(chou)氣(qi)(qi)。當容(rong)器的(de)(de)(de)(de)(de)(de)氣(qi)(qi)壓(ya)(ya)(ya)不(bu)(bu)再降低并且(qie)壓(ya)(ya)(ya)力保(bao)持在(zai)一定值時(shi)(shi)(shi)，次級壓(ya)(ya)(ya)力就是(shi)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)極限(xian)壓(ya)(ya)(ya)力。 2.流(liu)(liu)量(liang)(liang)。在(zai)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)吸入口(kou)，每(mei)單位(wei)時(shi)(shi)(shi)間的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體流(liu)(liu)量(liang)(liang)稱為泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流(liu)(liu)量(liang)(liang)。在(zai)真(zhen)(zhen)空(kong)(kong)技術中，流(liu)(liu)量(liang)(liang)單位(wei)以(yi)壓(ya)(ya)(ya)力*體積/時(shi)(shi)(shi)間表示，即Pa.m3/s或(huo)Pa.m3/h。通常，泵(beng)(beng)(beng)(beng)會給出流(liu)(liu)量(liang)(liang)與入口(kou)壓(ya)(ya)(ya)力的(de)(de)(de)(de)(de)(de)關系圖。 3.抽(chou)(chou)速(su)。在(zai)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)吸入口(kou)，每(mei)單位(wei)時(shi)(shi)(shi)間流(liu)(liu)動(dong)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體量(liang)(liang)稱為泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)速(su)率。即，通過將流(liu)(liu)量(liang)(liang)QA(Pa.m3/s)除(chu)以(yi)測試罩(zhao)中的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體A的(de)(de)(de)(de)(de)(de)分壓(ya)(ya)(ya)pA而獲得氣(qi)(qi)體A的(de)(de)(de)(de)(de)(de)泵(beng)(beng)(beng)(beng)送(song)速(su)度sA(m3/s)。典型的(de)(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)速(su)率與氣(qi)(qi)體類型有關。給定的(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)速(su)率表示某種氣(qi)(qi)體的(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)速(su)率。如果(guo)沒(mei)有特殊指示，則使用(yong)(yong)(yong)多指抽(chou)(chou)吸。 正確控制(zhi)(zhi)螺桿真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)流(liu)(liu)量(liang)(liang)不(bu)(bu)僅可以(yi)為設備提供良(liang)好的(de)(de)(de)(de)(de)(de)保(bao)護，還可以(yi)提高使用(yong)(yong)(yong)率。那么，該怎么做呢(ni)? 1，速(su)度控制(zhi)(zhi) 葉輪速(su)度的(de)(de)(de)(de)(de)(de)變化會改變螺桿真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流(liu)(liu)量(liang)(liang)曲線，并且(qie)曲線的(de)(de)(de)(de)(de)(de)特性(xing)不(bu)(bu)會改變。隨著速(su)度降低，曲線變平，揚程和流(liu)(liu)速(su)降低。 2，旁通閥(fa)(fa)調整 使用(yong)(yong)(yong)與泵(beng)(beng)(beng)(beng)并聯的(de)(de)(de)(de)(de)(de)中間閥(fa)(fa)。實(shi)際效果(guo)就...

羅(luo)茨(ci)真(zhen)空泵(beng)長時間(jian)使用后(hou)(hou)，會發生(sheng)不同的(de)(de)(de)(de)(de)(de)(de)故障(zhang)。一旦發生(sheng)故障(zhang)，我們(men)需要及時解決，以(yi)(yi)防止(zhi)(zhi)進一步(bu)的(de)(de)(de)(de)(de)(de)(de)惡(e)化和(he)(he)更(geng)多的(de)(de)(de)(de)(de)(de)(de)麻煩。氣(qi)(qi)蝕(shi)(shi)(shi)現象對真(zhen)空泵(beng)有一定(ding)的(de)(de)(de)(de)(de)(de)(de)影響。對于氣(qi)(qi)蝕(shi)(shi)(shi)現象，讓(rang)我們(men)教您(nin)解決方案(an)： 1、降低設備的(de)(de)(de)(de)(de)(de)(de)工(gong)作流(liu)(liu)體(ti)(ti)(ti)溫度(du)(du)(du)以(yi)(yi)防止(zhi)(zhi)氣(qi)(qi)蝕(shi)(shi)(shi)。 2、降低進氣(qi)(qi)溫度(du)(du)(du)可以(yi)(yi)間(jian)接降低水循環液的(de)(de)(de)(de)(de)(de)(de)溫度(du)(du)(du)，防止(zhi)(zhi)發生(sheng)氣(qi)(qi)蝕(shi)(shi)(shi)，還可以(yi)(yi)提高物料的(de)(de)(de)(de)(de)(de)(de)干燥速度(du)(du)(du)并提高設備的(de)(de)(de)(de)(de)(de)(de)利(li)用率(lv)。 3、在羅(luo)茨(ci)真(zhen)空泵(beng)中發生(sheng)氣(qi)(qi)蝕(shi)(shi)(shi)時，主要損壞是氣(qi)(qi)泡破(po)裂時葉輪和(he)(he)泵(beng)殼表面(mian)的(de)(de)(de)(de)(de)(de)(de)點(dian)蝕(shi)(shi)(shi)。 4、由于羅(luo)茨(ci)真(zhen)空泵(beng)氣(qi)(qi)蝕(shi)(shi)(shi)的(de)(de)(de)(de)(de)(de)(de)原因，眾所(suo)周知(zhi)，可以(yi)(yi)更(geng)換(huan)(huan)具(ju)有低飽和(he)(he)蒸(zheng)氣(qi)(qi)壓的(de)(de)(de)(de)(de)(de)(de)工(gong)作流(liu)(liu)體(ti)(ti)(ti)(要求工(gong)作流(liu)(liu)體(ti)(ti)(ti)具(ju)有良(liang)好(hao)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)動性以(yi)(yi)及與泵(beng)送氣(qi)(qi)體(ti)(ti)(ti)的(de)(de)(de)(de)(de)(de)(de)良(liang)好(hao)相容性)，以(yi)(yi)減少氣(qi)(qi)蝕(shi)(shi)(shi)和(he)(he)增加真(zhen)空度(du)(du)(du)。這樣做的(de)(de)(de)(de)(de)(de)(de)缺點(dian)之一是工(gong)作流(liu)(liu)體(ti)(ti)(ti)的(de)(de)(de)(de)(de)(de)(de)后(hou)(hou)處理問(wen)題(ti)，因此很少使用更(geng)換(huan)(huan)工(gong)作流(liu)(liu)體(ti)(ti)(ti)的(de)(de)(de)(de)(de)(de)(de)做法。 以(yi)(yi)上是羅(luo)茨(ci)真(zhen)空泵(beng)氣(qi)(qi)蝕(shi)(shi)(shi)解決方案(an)的(de)(de)(de)(de)(de)(de)(de)介紹。如果將來(lai)(lai)在使用機(ji)器的(de)(de)(de)(de)(de)(de)(de)過程(cheng)中出現氣(qi)(qi)穴(xue)現象，可以(yi)(yi)參考本文中描(miao)述(shu)的(de)(de)(de)(de)(de)(de)(de)方法進行處理。注意正確的(de)(de)(de)(de)(de)(de)(de)操作過程(cheng)。如果您(nin)自己無法解決問(wen)題(ti)，則(ze)需要找到專(zhuan)業(ye)人員來(lai)(lai)及時處理。希望對您(nin)有所(suo)幫助。

水環真空泵一直非常關注粗糙真空的獲得，例如真空過濾，真空水轉移，真空蒸發等。它已廣泛用于工業生產的許多過程中。 為了節約能源，有必要盡可能地節約能源。我們如何使用水環真空泵來節能? 1. 水環真空泵對角安裝，以減小彎頭或蝸殼，使水口面向水池。 2.縮短水環真空泵管道，拆除1米長的鋼管，并在10小時內節省0.21千克柴油。 3.擴大水環真空泵的出口管直徑。例如，將15米長的4米長水管替換為15厘米長的管道，并節省10公斤柴油10小時。 4.如果可以保持進水清潔，則可以卸下水環真空泵過濾器。 5.更換?
