羅茨真空(kong)泵(beng)經常檢查油品(pin)質(zhi)(zhi)量，應(ying)及時發現油品(pin)變質(zhi)(zhi)，更換新油，確保羅茨真空(kong)泵(beng)工作正常。羅茨真空(kong)泵(beng)求(qiu)購

結構緊湊、工作平衡(heng)可靠和(he)流(liu)量(liang)均勻，所以化工生產中多用(yong)來輸送或抽吸易(yi)燃(ran)、易(yi)爆和(he)有腐蝕性的氣體。水(shui)環式真空泵由于葉(xie)(xie)輪攪(jiao)拌(ban)液體，損失能(neng)(neng)量(liang)大(da)，故其效率很低。真空泵度(du)不夠可能(neng)(neng)原因(yin)：電(dian)機(ji)(ji)供(gong)電(dian)不足導致轉速不夠；供(gong)水(shui)量(liang)不足；葉(xie)(xie)輪與分配板(ban)(ban)之間(jian)的間(jian)隙過(guo)(guo)大(da)；機(ji)(ji)械密(mi)封破損導致漏水(shui)漏氣；葉(xie)(xie)輪磨損過(guo)(guo)多；循環水(shui)排(pai)不出。排(pai)除方法：檢(jian)查供(gong)電(dian)電(dian)壓(ya)是否在(zai)電(dian)機(ji)(ji)額定的電(dian)壓(ya)范圍(wei)內(nei)；加大(da)供(gong)水(shui)量(liang)（必須控制在(zai)正確的范圍(wei)內(nei)，否則會導致電(dian)機(ji)(ji)超(chao)載(zai)發(fa)熱）；調小葉(xie)(xie)輪與分配板(ban)(ban)的間(jian)隙（一般在(zai)0.15—0.20mm）；更換(huan)機(ji)(ji)械密(mi)封；更換(huan)葉(xie)(xie)輪；檢(jian)查出水(shui)口(kou)的管路。羅茨(ci)真空泵求購
