["1. 회전식 압입 泵 的疑问

2018-05-09View Original

Thread Content

제조부에 있는 회전식 압입 泵 中,出口阀开度过大会导致跳闸,开小了量不够还会憋压。 전기공작공이 왔어도 이유를 설명하지 못했고, 很纠结,备用泵总是坏,请各位大神帮解答心中疑惑。谢谢

이는 회전식 압离心泵 在在启动前关闭出口阀的原因

어떻게 해결할 수 있을까요?怎样才能让它正常运行啊

选型有问题,或者泵没达到要求

a. 회전식 압喷泵 流量范围本身就非常狭窄,打开出口阀门即在大流量下运行,超功率过载保护; b. 小流量时出口压力很大,时间长介质内能不断增加,介质温度升高损坏集流管,叶轮; c. 备用泵总是坏,考虑厂家质量问题,目前我公司生产的旋壳泵还未发现类似问题; 解决问题方案: a. 按照标准,额定功率应保持25%富余量,可能是与厂家沟通时没有明确大流量下不超功率,应保持在额定点工作,如果还超功率,一般来说,旋喷泵电机为变频电机,调节电机频率,减速运行; b. 尽量避免关闭阀门或者开度很小时使用; 3. 直观认为设备选型存在较大问题,参数设置偏离额定工况,短时间内运行不会引起大问题,但是长此以往对生产不利,建议联系厂家解决问题或者重新选型泵型。

회전식 泵 出口压力高,所以开大了憋压。 这种情况出现多久了?是生产方式就有还是最近才有的呢"
