Bulk density: mass per unit volume at a loose state of dust. True density: if trying to exclude particles and particles between the air inside the ventilation duct ventilation, as measured in the collapsed state mass per unit volume of dust Hangzhou ventilation pipeline company, we call it the true density. Dust mechanism: gravity, centrifugal force, inertial impaction, contacts, retention, diffusion, static electricity, cohesion. Inertial dust collector: To improve the effect of dust gravity settling chamber building ventilation pipe processing, you can set a variety of forms in which baffle airflow direction abrupt change, inertia or make use of the dust particles collide with baffles and traps . Suitable particle size 20 ~ 50μm. Hangzhou ventilation pipeline company, Riverside area ventilation pipes, ventilation pipe processing provided by Hangzhou Hangzhou Xingda ventilation equipment. Hangzhou Xingda ventilation equipment (www.tz1288.com/shop/index_6525.html) strong, credible, in Hangzhou, Zhejiang fan, ventilation equipment industry has accumulated a large number of loyal customers.
