在(zai)使(shi)用(yong)(yong)水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)泵時(shi)(shi),氣(qi)(qi)(qi)蝕是(shi)一個普遍的(de)(de)問(wen)(wen)題。水(shui)(shui)環(huan)泵的(de)(de)真(zhen)(zhen)空(kong)(kong)度(du)(du)不(bu)能滿足要求,影響(xiang)水(shui)(shui)環(huan)泵的(de)(de)正(zheng)常使(shi)用(yong)(yong)。因此,如(ru)何避免水(shui)(shui)環(huan)泵的(de)(de)氣(qi)(qi)(qi)蝕已成為許多(duo)用(yong)(yong)戶面臨的(de)(de)主要問(wen)(wen)題。水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)泵制造商向我們介紹了(le)以下內容。 在(zai)水(shui)(shui)環(huan)式真(zhen)(zhen)空(kong)(kong)泵運行期(qi)間,真(zhen)(zhen)空(kong)(kong)度(du)(du)越(yue)高,沸點越(yue)低(di)。當液體(ti)沸騰時(shi)(shi),會形成許多(duo)氣(qi)(qi)(qi)泡。這(zhe)些(xie)小氣(qi)(qi)(qi)泡很(hen)容易破裂(lie)(lie),在(zai)研(yan)磨過程中(zhong)葉(xie)輪(lun)會受到(dao)嚴(yan)重影響(xiang)。在(zai)白天(tian)和黑(hei)夜里(li),葉(xie)輪(lun)會破裂(lie)(lie)。如(ru)果(guo)嚴(yan)重損壞,則(ze)由于無法修復,可能會被迫更換。如(ru)果(guo)工(gong)作液流量(liang)過大,它們還(huan)會產(chan)生尖(jian)銳的(de)(de)噪音,因此有必(bi)要降低(di)流量(liang)。 處(chu)理(li)措施:針對這(zhe)種現(xian)象,可將(jiang)(jiang)葉(xie)輪(lun)設計為銅葉(xie)輪(lun),不(bu)銹(xiu)鋼(gang)葉(xie)輪(lun)等(deng)材料。水(shui)(shui)環(huan)泵的(de)(de)前面有一個氣(qi)(qi)(qi)蝕閥(fa)。當空(kong)(kong)化噪音太(tai)大時(shi)(shi),稍微轉動(dong)空(kong)(kong)化閥(fa)可以降低(di)噪音。但是(shi),由于真(zhen)(zhen)空(kong)(kong)度(du)(du)會大大降低(di),因此要求高真(zhen)(zhen)空(kong)(kong)度(du)(du)的(de)(de)工(gong)藝不(bu)適(shi)用(yong)(yong)。 在(zai)使(shi)用(yong)(yong)水(shui)(shui)環(huan)式真(zhen)(zhen)空(kong)(kong)泵的(de)(de)過程中(zhong),如(ru)果(guo)出現(xian)氣(qi)(qi)(qi)蝕現(xian)象,應立(li)即(ji)將(jiang)(jiang)其停止,并(bing)應采(cai)取有效(xiao)措施停止該過程。另外,在(zai)實(shi)踐中(zhong),遵循正(zheng)確的(de)(de)步(bu)驟可以有效(xiao)地防(fang)止出現(xian)氣(qi)(qi)(qi)穴問(wen)(wen)題。
