"Inflatable Air Blower" is the use of wind power and the indoor and outdoor temperature difference caused by natural air convection, rotation of the turbine in order to promote the use of centrifugal force and negative effects of the indoor stale hot air exhaust. Fan related to energy transmission and distribution systems, is very critical part of building energy efficiency. According to the National Air Conditioning Equipment Quality Supervision and Inspection Center for many years a lot of fans in the fan test showed rated conditions are a problem, and therefore the need for strict product standards in accordance with the requirements of production and manufacturing wind turbines. Fans just started working low vibration bearing parts, "Inflatable Air Blower" But with the longer running time, the dust will be uneven within the fan attached to the impeller, the gradual destruction of the fan balancing, make the gradual increase in bearing vibration When the fan once the vibration reaches the maximum allowed 11mm/s (with an amplitude value represents the maximum allowable value of below), the fan must be shut down to repair (remove dust accumulation, redo balancing). Because this time is very dangerous, the user must not be forced to use. Fan vibration when approaching a dangerous level, there will be vibration alarm instrumentation. Fan bearing temperature is normal when ≤70℃, if once raised to 70℃, electronic control shall (will) alarm. We should find out the reasons, first check whether the cooling water is normal? Bearing oil level is normal? If you can not find a reason, bearing temperature quickly rose to 90℃, "Inflatable Air Blower" electronic control should (will) alarm, stop signal again. Fan driving, parking or operation of the process, if found abnormal phenomenon should be checked immediately, inspection found little fault should promptly identify the cause of trying to eliminate. If found large fault (such as fans severe vibration, shock, severe rise in bearing temperature rise, etc.) should be immediately stopped and checked.
