About blower and exhaust fan of the role and the difference between them and the main role of the blower exhaust fan, in general, these points are the following, in order: positive pressure blower: it is mainly used to supply air within the evacuation routes to be able to maintain Positive pressure, thus avoiding the invasion of smoke affect the evacuation. Makeup air blower: it is mainly used in the large underground garage interior natural supplement inadequate smoke wind area, to be able to ensure that when the exhaust air can be complementary, avoid running up wind down effect caused by smoke. Exhaust fan: mainly used to remove harmful gases Nanchang fans offer, in order to avoid harmful gases indoor air pollution. Exhaust fan: it is mainly used in the initial fire smoke fire exclusion in the region, to prevent smoke diffusion affects the evacuees. Between the blower and exhaust fan, is somewhat different, specific examples are: a difference: the two can not use either. Difference between the two: in the fire protection system, if you use the blower, so there are only two, positive pressure blower and exhaust fan up.

Overall, since the cooling fan with energy-saving, environmentally friendly features Nanchang fans wholesale, concern in all sectors of the refrigeration research and development. We believe that only a good grasp of technology and grasp the market demand, the chiller used in cold storage will shine. Wet curtain of water pump What are the requirements we all know, the pump is to run power wet curtain cooling system, wet curtain whether the normal operation, the key is to choose the right pump, but how should choose, pay attention to what matters it? 1, clear the installation location of the pump, measure the distance to the water pump, water pump area and the use of the site to be supplied to the pump wet curtain height. 2, to determine pump selection, based on the measured data to determine the pump suction, head, flow, velocity, selected pumps are generally used self-priming centrifugal pipeline pump or submersible pump.

Practice for high pressure centrifugal fan high pressure centrifugal fan operating procedures as follows: 1 fan before start, closing the intake air control valve, the wind slightly open valve. The gap between the various parts of the fan to check the suitability of the rotating part and whether the collision between the fixed part or friction phenomenon. 2. Coupling not someone near Nanchang fans, and to add security cover. 3. The bearing housing oil level is at the minimum and maximum oil level lines, lines, meters and other is normal, the cooling system is working. 4. After the fan starts to gradually open the damper until the specified load. Fan during operation, the bearing temperature can not be higher than 40 ℃, the surface temperature can not be higher than 70 ℃. 5. If the fan phenomenon occurs severe vibration or impact or bearing temperature abnormal phenomenon, should immediately emergency stop, and promptly investigate the cause.
