水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)真(zhen)(zhen)空泵是(shi)(shi)什么? 離(li)心力效應(ying)產生水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)的(de)(de)(de)自旋(xuan),以(yi)(yi)獲得水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)真(zhen)(zhen)空泵的(de)(de)(de)真(zhen)(zhen)空。主要用(yong)(yong)于吸入(ru)空氣(qi),高真(zhen)(zhen)空度可達85%以(yi)(yi)上(shang)。它由(you)泵體和(he)(he)泵蓋組成(cheng)。葉輪由(you)均勻地呈放(fang)射(she)狀分布的(de)(de)(de)多個葉片和(he)(he)輪轂構(gou)成(cheng)。在啟(qi)動泵之(zhi)(zhi)前(qian)(qian),向工作(zuo)(zuo)(zuo)(zuo)室中(zhong)注入(ru)適(shi)量(liang)的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)或(huo)其他工作(zuo)(zuo)(zuo)(zuo)流(liu)體。啟(qi)動后,由(you)于離(li)心力的(de)(de)(de)作(zuo)(zuo)(zuo)(zuo)用(yong)(yong),水(shui)(shui)(shui)(shui)(shui)(shui)被拋到工作(zuo)(zuo)(zuo)(zuo)室的(de)(de)(de)壁上(shang),形成(cheng)旋(xuan)轉水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)。 水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)泵具有(you)(you)以(yi)(yi)下優點: (1)結(jie)構(gou)簡單,制造精度不高,易(yi)于加工。操作(zuo)(zuo)(zuo)(zuo)簡單,維(wei)護方(fang)便。 (2)結(jie)構(gou)緊湊,泵一般直接(jie)與(yu)電動機連接(jie),轉數高。采用(yong)(yong)較(jiao)小(xiao)的(de)(de)(de)結(jie)構(gou)尺寸,可以(yi)(yi)獲得較(jiao)大的(de)(de)(de)位移。 (3)泵腔(qiang)內沒(mei)有(you)(you)金屬摩擦(ca)表面,也無需潤(run)滑(hua)泵。旋(xuan)轉部(bu)分和(he)(he)固定部(bu)分之(zhi)(zhi)間的(de)(de)(de)密封(feng)可以(yi)(yi)通過水(shui)(shui)(shui)(shui)(shui)(shui)封(feng)直接(jie)完成(cheng)。 (4)泵腔(qiang)內壓縮(suo)氣(qi)體的(de)(de)(de)溫度變化小(xiao),可以(yi)(yi)認為是(shi)(shi)等(deng)溫壓縮(suo),因此(ci)可以(yi)(yi)去(qu)除易(yi)燃易(yi)爆氣(qi)體。 (5)由(you)于沒(mei)有(you)(you)排(pai)氣(qi)門和(he)(he)摩擦(ca)表面,因此(ci)可以(yi)(yi)去(qu)除含(han)塵氣(qi)體,可冷凝氣(qi)體和(he)(he)氣(qi)水(shui)(shui)(shui)(shui)(shui)(shui)混合物。 水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)泵還(huan)具有(you)(you)以(yi)(yi)下缺點: (1)低效率,通常為30%左右(you),最好達到50%。 (2)真(zhen)(zhen)空度低。這不僅是(shi)(shi)由(you)于結(jie)構(gou)限制,而且更(geng)重要的(de)(de)(de)是(shi)(shi),工作(zuo)(zuo)(zuo)(zuo)流(liu)體的(de)(de)(de)飽和(he)(he)蒸氣(qi)壓。 水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)真(zhen)(zhen)空泵拆卸(xie)時應(ying)注意(yi)什么? (1)告訴Electric拆線(xian),停電,并貼上(shang)警告牌“如果有(you)(you)人正在維(wei)修,請勿移動”。 (2)水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)真(zhen)(zhen)空泵在與(yu)系統連接(jie)的(de)(de)(de)管道上(shang)斷開連接(jie)或(huo)添加盲板。 (3)拆卸(xie)水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)真(zhen)(zhen)空泵之(zhi)(zhi)前(qian)(qian),應(ying)先通過排(pai)水(shui)(shui)(shui)(shui)(shui)(shui)孔將水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)泵中(zhong)的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)排(pai)出。 (4)拆卸(xie)水(shui)(shui)(shui)(shui)(shui)(shui)環(huan)真(zhen)(zhen)空泵時,應(ying)小(xiao)心卸(xie)下所有(you)(you)墊片。如果損壞,請用(yong)(yong)...
