Thank you for your attention to Zhongyuan innovation [Knowledge News Information] column! Xiaoman is one of the 24 solar terms and the two solar terms in summer. Small fullness - It means that the seeds of summer crops begin to fill up, but are not mature, just small fullness, not big fullness. innovation remind you Cement plant power plant powder material lifting and conveying equipment industry customers: In the full season, everything is thriving and growing vigorously, and the physiological activities of the human body are also in a vigorous period. The consumption of nutrients is more than the 24 solar terms in the four seasons. Therefore, it should be timely and properly supplemented to protect the internal organs of the body from damage. Thank you for following the Zhongyuan Innovation Material Powder Conveying Pump Co. LTD website http://ceshi2.66554433.cn, and wish you May your hard work and dedication bring you continued success and happiness!!

气流粉末输送泵在输送中压力损失的原因

Time: 2016/10/14 9:02:44

    流粉末输送泵在输送中压力损失的原因。在气力输送过程中,粉末输送泵输送压缩空气和被输送物料所消耗的一切能量,都是由输送空气压缩机来承担的。粉末输送泵输送管道内压力损失随着物料运动状态变化而变化,因此想通过小管径输送管道的实验结果来指导两相流压力损失计算,由于输送流动状态不同,因此不可能有一个统一的计算方法。下面我们来为大家来说一下粉末输送泵产生输送管道内压力损失的主要原因。
    1:由于在输送管道内压缩空气速度分布不均,因此散布在输送管道气流中的压缩空气所携带的颗粒受到的推力也不相同。
    2:被输送物料的颗粒并不是*呈球体状,很容易受到不均匀推力而产生旋转。
    3:被输送物料颗粒间和颗粒与输送管道内壁之间不断的发生碰撞、摩擦。
    4:被输送物料的物理性能,如密度、黏性、温度、粒径等
    5:输送速度。
