罗茨鼓风机是冲天炉配套的重要组成部份,其鼓出的风量风压不足,会直接影响冲天炉熔炼操作,给铸铁件质量带来不利因素。我厂的罗茨鼓风机,自从64年从外厂调拨进厂后,在试用过程中,出现风量风压不足,造成熔化速度慢,铁水温度低。通过分析,由于风叶与风叶之间、风叶与机壳之间间隙太大,漏风太多所致。我们在 Roots Blower is an important part of the supporting cupola, the lack of wind pressure out of its bulky, will directly affect the cupola melting operations, cast iron parts to bring unfavorable quality. Roots blowers of our plant, since the transfer from the factory after 64 years into the plant, in the trial process, there is insufficient wind pressure, resulting in slow melting, hot metal temperature is low. Through analysis, due to the blade and the blade, the gap between the blade and the casing is too large, due to excessive air leakage. we are at
