Shanxi fan bearing temperature is too high: ① bearing severe vibration; ② viscosity of the lubricant does not deteriorate or contain foreign materials, inadequate or excessive lubricant filling; ③ Rolling bearings damaged or bent, the bearing inner or outer ring too loose tolerances or too tight. Shanxi fan motor current or temperature is too high: ① car when not shutting the inlet pipe; ② sent gas contains viscous material; ③ spindle speed exceeds the rating; ④ bearing box severe vibration; ⑤ motor input voltage is too Current low or missing items. We have to look at high temperature fan air volume and pressure of the concept of Shanxi fire fans suppliers, wind 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 ventilation area, that is, the larger the outer diameter of the impeller blades, the greater the amount of wind. The larger the amount of wind, the air, the greater heat absorption, thermal effect is more obvious fan. Shanxi blower pressure for proper ventilation, equipment needed to overcome the resistance of the supply fan, we generally will change the value of the measured pressure is called the static pressure, which is parallel to the surface pressure of the gas on the role of the object, the main fan manufacturers is the use of holes perpendicular to its surface measuring out. In practice, Shanxi fans suppliers, not to say that strong ventilation air volume capacity. Fans also take into account the major manufacturers of air is flowing Shanxi blower suppliers, air flow path in its encounter obstacles, so when the wind increases, pressure decreases. Sometimes in order to reduce the system impedance, even the choice of a smaller size fan, also can obtain the same amount of wind.
