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

 Boiler fan in the design is based on maximum operating conditions to be considered hot air fuel prices, in actual use, there are a lot of time fans need to be adjusted according to actual conditions, the traditional approach is to switch the throttle valve to adjust the way it Species adjustment mode increases throttle loss for the air system, when there will be in the starting inrush current, and the system itself is the stage of adjustment, adjust the speed is slow, reduce the loss of ability is very limited, but the entire system Working in fluctuating; and through the installation of the inverter (device) on the boiler fan can solve these problems once and for all fuel Heaters company, allows the system to work flat and stable state, and to recover their investments through frequency energy. Fans started working low vibration bearing parts, but with a longer running time coal heater manufacturers, interior blower fan dust unevenly adhered to the impeller, the gradual destruction of the fan balancing, the bearing vibration gradually increase Great, once vibration reaches the maximum allowed fan 11mm / s (with the amplitude value represents the maximum allowable value of below), 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. The maximum allowable turbine bearing vibration values ??are: (1) The effective display of bearing vibration speed: 11mm / s. (2) the following values ??bearing amplitude display: motor synchronous speed of 3000 rev / min: maximum allowable value: 0.1mm (double amplitude) Motor synchronous speed of 1500 r / time: The maximum allowable values ??are: 0.2mm (double amplitude) Motor synchronous speed of 1000 rpm / min: maximum allowable value: 0.31mm (double amplitude) Motor synchronous speed of 750 revolutions / min: maximum allowable value: 0.4mm (double amplitude) Motor synchronous speed 600 r / time: The maximum allowable value: 0.5mm (double amplitude) Motor synchronous speed of 500 rev / min: maximum allowable value: 0.6mm (double amplitude) wholesale coal heater, Qingzhou Min Wei Machinery (already certification), the fan is provided by Qingzhou Wei Min Machinery Co.
