Centrifugal wind chassis choice points and Failure Analysis centrifugal wind chassis is initiated by the motor rotation of the impeller, the wind chassis fire ventilation, gas impeller blades rotating force, acting on the gas to energy growth, the gas in the centrifugal force of the impeller thrown around, resolved to speed scroll type casing can be converted into pressure energy, when the gas impeller exclusion, pressure impeller is lower than the inlet pipe pressure, the new gas at a pressure difference suction impeller, low noise wind chassis, gas is continuously kept marginalized from the pump, air box, a centrifugal fan product choice points 1. wind chassis air flow control parameter selection, total pressure, efficiency, noise, and electrical power. Centrifugal and axial flow. 2. Fan the provision of the wind chassis, muffler favor. 3. When the fan selection should consider the loss of air leakage pipeline system, strategy errors, and negative real problems ventilator wind, air pressure, and as usual acceptance of wind capacity of 1.05 to 1.1, pressure is peaceful coefficient of 1.10 to 1.15 . But I do not accept too large to guard fan long run in a low efficiency area. 4. meticulous pipe network resistance characteristic feature of standing room and fan relationship. For the fan can run firm, should be similar to what the fan at its highest efficiency point, what point fan performance curve to the right of the peak point of the total pressure (ie, the amount of wind side, and as usual all-peak pressure of 80 %). Exhaust wind chassis to create greater value for our exhaust wind chassis has a lot of advantages on the performance of the manufacturing process, the use of exhaust wind chassis performance advantage can create a lot of value for us. The growth rate of the exhaust air box special equipment manufacturing industry is relatively high, and there is a large increase over the previous year. Exhaust air box factory direct exhaust air box lowest price significantly increase industry profit growth, significant economic benefits, but also the production of special air box, in which the special equipment manufacturing industry profit growth to enhance the anomalies. In fact, in the exhaust duct chassis use, we will find that there are still many things to pay attention to the. When the exhaust wind chassis two-speed exhaust fan test, you should start low, and check the direction of rotation is correct; it must be at the start and then start the high-speed fan still prevent reverse rotation speed, causing the switch trips and motor damage. Centrifugal fan and wind chassis, the required air inlet fully open higher power. If the inlet operated fully open, there is risk of damage the motor. When the exhaust fan will test the best fan inlet or outlet piping valve closure, the valve operation will be gradually opened up to the desired operating mode, and note that the exhaust fan operating current exceeds the rated current. Sheng clean air conditioning (Figure), low-noise wind chassis, the chassis by the Texas wind Sheng provide clean air-conditioning Limited. Texas Air Conditioning Equipment Co., Ltd. Sheng-purification (www.dzhffj.com) located in Dezhou City, Shandong Province, Wuhan City acres of industrial park. Scraps and development in the wave of market economy, the current clean air conditioning Sheng Tong has a high profile in fan, ventilation equipment, and enjoys a good reputation. Sheng purification of air conditioning made the whole network business alliance certification, marking our service and management level has reached a new height. Sheng clean air-conditioning staff willing to work with all people of insight and common development, for a better future.
