Exhaust fan performance 'regulatory exhaust fan fire, is to let the wind pressure or wind turbines achieve a standard of fans artificially controlled. Through effective regulation, allowing high pressure air blower in ensuring the stable operation of the conditions necessary to meet the production requirements for flow or pressure but also to maximize energy savings. Although users will use a different adjustment method, but achievable goal is the same, but the effect is there are some differences. Select the adjustment method is not only related to the effect of exhaust fan fire, more fan energy savings will have a huge impact, so choose an appropriate adjustment method to keep fans on the premises to achieve the same effect of energy-saving effect. The only way to improve the efficiency of the fan, to achieve energy efficient, but also to better protect the fans, to extend efficiency. Feature Highlights exhaust fan fire performance is such that its effect is that these energy-efficient exhaust fans offer, we must operate in accordance with the above instructions correctly to obtain better results. For high-level underground chamber usually exhaust ventilation and Class 2 speed things work situation, two-speed electric ho different purpose still favorable. Switch to a low-speed two-speed fan runs fast, with a lot of ho enhance speed, wind row also corresponds greatly enhance exhaust fan pictures, then the system immediately become smoke from the exhaust Yi situation. However, in the planning process, and we will meet the electrical control of two-speed fan problem, basically speaking from how to deal with the motor windings Δ connection Y connection to double conversion and interlock, fire linkage of self-control and manual; Fans in the fast circulation of defense down, and how to ensure the maximum level of credibility do smoke, how to ensure the power supply and other problems. Following on as part of the two-speed fan control discussions. Because the underground chambers by underground space, limiting factors and exhaust fan manufacturers in the wind and air pressure and other factors of satisfaction factor, the fire's smoke and exhaust ventilation system is usually used in combination can, therefore, we at underground garage using two-speed fan, the same is basically the same fans and the same duct. Under normal circumstances, as the exhaust ventilation fan running at low speed applications, when a fire, fan into a fast run both stand as fire exhaust fan applications. So a machine 2 with not only decrease the cost of health made, save space, more important thing is to greatly enhance the configuration of the application rate and credibility. Should the smoke exhaust and harm are basically two systems to leave, but only exhaust fan exhaust fan fire, when the fire bet to produce runs, usually fewer applications, as revealed problems not easily be discovered in time and get the repairs, while real fire, is not easy to guarantee Hang Shun betting applications. The two-speed fan just to overcome this deficiency, usually as an exhaust fan running, the problem appears to be excavated and get timely repairs, often in a good posture drops ready.
