How fire exhaust fan bearing location should be repaired to maintain it exhaust fan fire has now become a leader in the wind turbine industry, everyone it has no stranger to ultra-high performance, but on fire exhaust fan bearing location, How should we carry out repair and maintenance of it, today as we detail below: a fire exhaust fan bearings check the oil supply situation, if there is leakage found the box, first tighten the bolts on the cover on it and see. how kind of effect, exhaust fan, does not work, then replace with new packing. II. If you are replacing the fire exhaust fan bearings, we must ensure that the new bearings and bearing housing clean, but also to the new bearing into the oil placed 75 degrees around the set period of time and then come up with the shaft. In the process of loading the bearing, remember forced to install, do not damage the shaft, exhaust fan supply, but also pay attention to maintenance and other supporting equipment. III. General fire exhaust fan bearing lubricant is better replaced once a quarter, at the beginning of running axial fan, when the first oil change, to make the fan work 200 hours or so, the next oil change in one to two months, after the work is checked once a week, to see whether the transformation, normal, you can change the oil two to four months, it would be best to use a unified factory lubricant replacement To be noted is that the exhaust fan sales, have removed the old oil and clean the fuel tank and then replaced with new oil. The difference between the role of exhaust fan exhaust fan and positive pressure fans is this: When the basement fire, there is a lot of smoke produced, HTF exhaust fan, this time, the fire started with the exhaust fan, the smoke from the fire area to exclude . In addition, it can usually exhaust fan in a basement also for air. Positive pressure blower is pointing escape corridor air supply fan. It outdoor air pressure into the interior. When the building is on fire, it will produce a lot of smoke, carbon monoxide and other toxic gases and block the line of sight, through positive pressure blower air to escape the fire stairs, indoor smoke can not reach the stairs, to create conditions for people to escape. If the blower is located in the roof of high-rise buildings, sending through the pipeline to the stairwell or elevator shaft front room fan, then known as positive pressure air supply, but also to its role when the fire broke out in the floor, to the stairwell or elevator room blower, guarantor The safe evacuation.
