Coal heater wholesale, China Qingzhou Wei Machinery (certified), fans

 Of all walks of life in various types of mechanical and electrical equipment and motor fans supporting about 60% of the installed capacity of the motor, energy consumption accounts for about one-third of total electricity generation. It is particularly worth mentioning is the coal heater manufacturers, the majority of fans in the course there is the phenomenon of large horse-drawn cart, coupled due to changes in production, technology and other aspects, the need for frequent adjustment gas flow, pressure, temperature and the like; With the improvement of the last decade inverter technology development. Frequency performance increasingly perfect, has been widely used in AC Speed ??in different fields. The enterprise has brought considerable economic benefits, and promote the industrial production process automation. Fan test items wind, air pressure, input power, speed, range, energy efficiency. Fan noise detection and fan vibration detection mainly based on GB / T 2888-2008 "fan and blower noise measurement method", JB / T 8690-1998 "Industrial Fan noise limits", JB / T 8689-1998 "Fan vibration detection and restrictions ", GB 9068-1988" Determination of heating, ventilation and air conditioning equipment noise sound power - Engineering method ", GB / T 3767-1996" Determination of sound power levels of noise sources reflecting plane free sound pressure field engineering method. " Fans started work bearing parts of the vibration is small fuel hot air companies, but with longer, dust inside the fan operating time will be uneven attached to the impeller, the gradual destruction of the fan balancing fan bearing vibration gradually increase When the fan once the vibration reaches the maximum allowed 11mm / s (with the amplitude value represents the maximum allowable values ??are as follows) Fuel Heaters price, 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. When approaching the danger fan vibration value, there will be vibration meter alarm.
