粉末输送泵的管道疏通问题详细解析

    巩义创新制造的粉末输送泵比提升机、螺旋输送机节省80-98%的配件维护费,并具有结构简单、维护方便等优点;粉末输送泵同时具有体积小、风压低、运转可靠、几乎没有易损件等诸多优点。粉末输送泵可输送物料3—500M,提升高度可达50M,粉末输送泵是一种综合性价比更高的输送粉状物料的专业设备。粉末输送泵可用于:火力发电、水泥、粉煤灰、白灰、石膏粉、精细化工等物料比≤1.6以下企业的生产和使用。

    粉末输送泵管道疏通注意事项:

  一:由于低速栓状流气力输送系统粉末输送泵在一般的情况下,一台锅炉需配置两条以上输送管道,因此具备采用正吹反抽疏通管道装置的条件。采用该粉末输送泵装置要比采用补气环疏通输送管道效果明显,而且疏通的速度快。
  二:在输送管道起始端设置气动正吹蝶阀、气动反抽球阀和输送管道压力开关等组成疏通管道装置,采用了PLC程序控制。
  三:当输送管道压力开关输出超高信号时,关闭L型仓泵气动进气阀,开启气动反抽球阀,利用锅炉尾部烟道内的负压对输送管道内干灰进行反抽,反抽时间为30s.此时,如果输送管道内压力仍没有下降到正常值,则关闭反抽气动球阀,开启气动正吹蝶阀,利用输送压缩空气对输送管道进行加压,正吹时间为90s.反抽、正吹反复动作,直到输送管道内压力恢复正常,由输送管道压力开关输出信号,自动解除疏通管道程序,恢复L型仓泵输送正常运行程序。
  四:输送系统正常运行时,气动正吹蝶阀、气动反抽球阀处于关闭状态
