We have to look at the concept of Shanxi fan air volume and pressure, the air volume actually refers to the speed of the fan-ventilated area and the plane of the plot. The ventilation area is subtracted from the value of the projected area of ??the outlet area of ??the tongue at the vortex obtained, the plane is the velocity of the air flow rate through time. When the plane speed is constant, the larger the area of ??Jiaozuo ventilation fan manufacturers, which is the larger outer diameter of the blades of the impeller fan manufacturers, the greater the amount of wind. The larger the amount of wind, the air, the greater heat absorption, thermal effect is more obvious fan. What is the role of a fan in the mine? Whether it is coal or metal mining, mining can not be separated in Anyang ventilation blower fan manufacturers, fan acting on the task of mine has four points: (1) the fresh air to the mine Xinxiang dust blower manufacturers, supply underground staff breathing ; (2) the external manager of harmful gases and dilute exhaust wells, to ensure that no explosion or dangerous occurrence; (3) the discharge of coal dust flying the well outside the well; (4) to adjust the temperature of the well, so that the normal operation of the staff. As can be seen from here, ventilation doing good or bad, is directly related to life safety and production development of the mine workers.
