在(zai)(zai)(zai)(zai)使(shi)用(yong)(yong)水(shui)(shui)環(huan)(huan)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)時,氣(qi)(qi)蝕是(shi)一(yi)(yi)個普遍的(de)(de)問(wen)題(ti)。水(shui)(shui)環(huan)(huan)泵(beng)(beng)(beng)(beng)的(de)(de)真(zhen)空(kong)(kong)(kong)度不能(neng)滿足(zu)要(yao)(yao)求,影(ying)響水(shui)(shui)環(huan)(huan)泵(beng)(beng)(beng)(beng)的(de)(de)正常使(shi)用(yong)(yong)。因此,如何避免水(shui)(shui)環(huan)(huan)泵(beng)(beng)(beng)(beng)的(de)(de)氣(qi)(qi)蝕已(yi)成為(wei)許多(duo)(duo)用(yong)(yong)戶面臨的(de)(de)主要(yao)(yao)問(wen)題(ti)。水(shui)(shui)環(huan)(huan)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)制造商向我們介紹(shao)了以下(xia)內容(rong)。 在(zai)(zai)(zai)(zai)水(shui)(shui)環(huan)(huan)式(shi)(shi)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)運行期間,真(zhen)空(kong)(kong)(kong)度越高,沸(fei)點越低(di)。當液(ye)體沸(fei)騰時,會形(xing)成許多(duo)(duo)氣(qi)(qi)泡(pao)。這些小氣(qi)(qi)泡(pao)很(hen)容(rong)易破裂(lie),在(zai)(zai)(zai)(zai)研(yan)磨(mo)過(guo)程(cheng)(cheng)中(zhong)葉輪(lun)會受到嚴(yan)重(zhong)影(ying)響。在(zai)(zai)(zai)(zai)白天和(he)黑(hei)夜里,葉輪(lun)會破裂(lie)。如果(guo)嚴(yan)重(zhong)損壞,則(ze)由于無法修復,可能(neng)會被迫更(geng)換。如果(guo)工(gong)作(zuo)液(ye)流量過(guo)大,它們還會產生(sheng)尖銳的(de)(de)噪(zao)音,因此有必要(yao)(yao)降低(di)流量。 處理措(cuo)施:針對這種現(xian)(xian)象,可將(jiang)葉輪(lun)設計為(wei)銅葉輪(lun),不銹鋼葉輪(lun)等材料。水(shui)(shui)環(huan)(huan)泵(beng)(beng)(beng)(beng)的(de)(de)前面有一(yi)(yi)個氣(qi)(qi)蝕閥。當空(kong)(kong)(kong)化噪(zao)音太大時,稍(shao)微轉動空(kong)(kong)(kong)化閥可以降低(di)噪(zao)音。但(dan)是(shi),由于真(zhen)空(kong)(kong)(kong)度會大大降低(di),因此要(yao)(yao)求高真(zhen)空(kong)(kong)(kong)度的(de)(de)工(gong)藝不適用(yong)(yong)。 在(zai)(zai)(zai)(zai)使(shi)用(yong)(yong)水(shui)(shui)環(huan)(huan)式(shi)(shi)真(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)過(guo)程(cheng)(cheng)中(zhong),如果(guo)出現(xian)(xian)氣(qi)(qi)蝕現(xian)(xian)象,應立即將(jiang)其停(ting)止(zhi),并(bing)應采取有效措(cuo)施停(ting)止(zhi)該過(guo)程(cheng)(cheng)。另外,在(zai)(zai)(zai)(zai)實踐中(zhong),遵循正確的(de)(de)步驟(zou)可以有效地防止(zhi)出現(xian)(xian)氣(qi)(qi)穴問(wen)題(ti)。
