眾(zhong)所(suo)周知，對于各種真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)性(xing)(xing)能，都有規定的(de)(de)(de)(de)(de)(de)測(ce)試(shi)方(fang)法來測(ce)試(shi)該(gai)性(xing)(xing)能的(de)(de)(de)(de)(de)(de)性(xing)(xing)能，主(zhu)要(yao)性(xing)(xing)能是極限壓(ya)(ya)(ya)力(li)(li)，流(liu)(liu)(liu)量(liang)(liang)(liang)和抽速(su)(su)(su)。這(zhe)次(ci)，小編打算討論螺(luo)桿真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)(liang)，例(li)如如何控(kong)制(zhi)其(qi)流(liu)(liu)(liu)量(liang)(liang)(liang)，流(liu)(liu)(liu)量(liang)(liang)(liang)不(bu)足(zu)的(de)(de)(de)(de)(de)(de)原因以(yi)及(ji)如何消除此問(wen)題。相信許多用戶對這(zhe)些問(wen)題感到困(kun)惑，不(bu)用擔(dan)心，請(qing)跟(gen)隨螺(luo)桿真(zhen)空(kong)(kong)泵(beng)(beng)(beng)廠家進行了解。 首(shou)先(xian)，讓我(wo)們簡單介紹一(yi)下(xia)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)主(zhu)要(yao)性(xing)(xing)能的(de)(de)(de)(de)(de)(de)概念。 1.極限壓(ya)(ya)(ya)力(li)(li)。真(zhen)空(kong)(kong)泵(beng)(beng)(beng)與(yu)檢測(ce)容(rong)器(qi)相連，放置待測(ce)氣(qi)(qi)體(ti)后，連續長時(shi)間(jian)抽氣(qi)(qi)。當容(rong)器(qi)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)壓(ya)(ya)(ya)不(bu)再降低并且(qie)壓(ya)(ya)(ya)力(li)(li)保持在(zai)一(yi)定值時(shi)，次(ci)級壓(ya)(ya)(ya)力(li)(li)就(jiu)是泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)極限壓(ya)(ya)(ya)力(li)(li)。 2.流(liu)(liu)(liu)量(liang)(liang)(liang)。在(zai)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)吸(xi)入口(kou)(kou)，每單位時(shi)間(jian)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)流(liu)(liu)(liu)量(liang)(liang)(liang)稱為(wei)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)(liang)。在(zai)真(zhen)空(kong)(kong)技術(shu)中，流(liu)(liu)(liu)量(liang)(liang)(liang)單位以(yi)壓(ya)(ya)(ya)力(li)(li)*體(ti)積/時(shi)間(jian)表(biao)示(shi)，即(ji)Pa.m3/s或Pa.m3/h。通常，泵(beng)(beng)(beng)會給(gei)(gei)出流(liu)(liu)(liu)量(liang)(liang)(liang)與(yu)入口(kou)(kou)壓(ya)(ya)(ya)力(li)(li)的(de)(de)(de)(de)(de)(de)關系圖。 3.抽速(su)(su)(su)。在(zai)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)吸(xi)入口(kou)(kou)，每單位時(shi)間(jian)流(liu)(liu)(liu)動(dong)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)量(liang)(liang)(liang)稱為(wei)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)速(su)(su)(su)率(lv)(lv)。即(ji)，通過將流(liu)(liu)(liu)量(liang)(liang)(liang)QA(Pa.m3/s)除以(yi)測(ce)試(shi)罩中的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)A的(de)(de)(de)(de)(de)(de)分壓(ya)(ya)(ya)pA而獲得氣(qi)(qi)體(ti)A的(de)(de)(de)(de)(de)(de)泵(beng)(beng)(beng)送(song)速(su)(su)(su)度sA(m3/s)。典型的(de)(de)(de)(de)(de)(de)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)速(su)(su)(su)率(lv)(lv)與(yu)氣(qi)(qi)體(ti)類型有關。給(gei)(gei)定的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)速(su)(su)(su)率(lv)(lv)表(biao)示(shi)某種氣(qi)(qi)體(ti)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)速(su)(su)(su)率(lv)(lv)。如果沒有特殊指示(shi)，則使(shi)用多指抽吸(xi)。 正確控(kong)制(zhi)螺(luo)桿真(zhen)空(kong)(kong)泵(beng)(beng)(beng)流(liu)(liu)(liu)量(liang)(liang)(liang)不(bu)僅(jin)可(ke)以(yi)為(wei)設備提供良好(hao)的(de)(de)(de)(de)(de)(de)保護，還可(ke)以(yi)提高使(shi)用率(lv)(lv)。那么，該(gai)怎么做呢? 1，速(su)(su)(su)度控(kong)制(zhi) 葉輪速(su)(su)(su)度的(de)(de)(de)(de)(de)(de)變(bian)化(hua)會改變(bian)螺(luo)桿真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)(liang)曲(qu)(qu)線，并且(qie)曲(qu)(qu)線的(de)(de)(de)(de)(de)(de)特性(xing)(xing)不(bu)會改變(bian)。隨著速(su)(su)(su)度降低，曲(qu)(qu)線變(bian)平，揚程和流(liu)(liu)(liu)速(su)(su)(su)降低。 2，旁通閥調整(zheng) 使(shi)用與(yu)泵(beng)(beng)(beng)并聯的(de)(de)(de)(de)(de)(de)中間(jian)閥。實際效(xiao)果就(jiu)...

離(li)心(xin)泵(beng)有很多不同(tong)的(de)(de)(de)類型，對(dui)于不同(tong)液體需要選(xuan)擇不同(tong)的(de)(de)(de)離(li)心(xin)泵(beng)，液體粘度不大(da)(da)(da)、流(liu)量(liang)較大(da)(da)(da)、揚程不高(gao)時，宜(yi)選(xuan)用(yong)往復泵(beng)；液體粘度較大(da)(da)(da)、流(liu)量(liang)較小、揚程不高(gao)或(huo)含(han)有氣泡時，可選(xuan)用(yong)旋渦泵(beng)；液體粘度較大(da)(da)(da)、流(liu)量(liang)較小、揚程較高(gao)時，宜(yi)選(xuan)用(yong)轉子泵(beng)。 理解類型的(de)(de)(de)選(xuan)擇是最基本的(de)(de)(de)，只有正(zheng)確選(xuan)擇才能使得正(zheng)常運轉，但(dan)是我(wo)們在(zai)使用(yong)中經常會遇到(dao)突然(ran)泄(xie)漏的(de)(de)(de)問題，這又是哪些(xie)原因(yin)(yin)造成(cheng)的(de)(de)(de)呢？下面就(jiu)來分析一下。 1、抽空、氣蝕或(huo)較長(chang)時間憋(bie)壓，導(dao)致密(mi)封破壞； 2、對(dui)泵(beng)實際輸出量(liang)偏小，大(da)(da)(da)量(liang)介(jie)(jie)(jie)質泵(beng)內循環，熱量(liang)積聚(ju)，引(yin)起(qi)介(jie)(jie)(jie)質氣化，導(dao)致密(mi)封失效； 3、回流(liu)量(liang)偏大(da)(da)(da)，導(dao)致吸(xi)人管側容器(塔、釜、罐、池)底部沉(chen)渣(zha)泛起(qi)，損(sun)壞密(mi)封； 4、對(dui)較長(chang)時間停運，重新起(qi)動時沒有手動盤車(che)，摩(mo)擦(ca)副因(yin)(yin)粘連而扯壞密(mi)封面； 5、介(jie)(jie)(jie)質中腐(fu)蝕性、聚(ju)合性、結(jie)膠性物質增多； 6、環境溫度急劇變(bian)化； 7、工況頻繁變(bian)化或(huo)調整； 8、突然(ran)停電或(huo)故(gu)障停機等。 當遇到(dao)突然(ran)泄(xie)漏的(de)(de)(de)問題，我(wo)們一定要正(zheng)確分析，以采取對(dui)的(de)(de)(de)措施，以免(mian)造成(cheng)不要的(de)(de)(de)損(sun)失。

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?
