The rotary blower has an inlet, and naturally there will be an outlet. Check whether the inlet filter is blocked. If it is blocked, it needs to clean the contents in time or clean the filter directly. It takes a long time and a long journey from the factory to the factory. No matter whether it is on the road or during loading and unloading, there may be deviation. Therefore, loosen the screw first, tap it gently with a hammer, select a wooden hammer, and then pull the belt by hand after probing. It is OK to tighten the screw without sticking points. If the diameter of the selected rotary blower impeller is much larger than that of the original fan impeller, in order to use the original annoying motor shaft, bearing and support, the machine start time, the strength of the original fan components, and the critical speed of the shaft must be calculated.
For the ventilation system with noise elimination requirements, the ventilator with high efficiency and low impeller circumferential speed should be selected first to work at the highest efficiency point; Corresponding noise elimination and vibration reduction measures shall also be taken according to the transmission mode of noise and vibration generated by the ventilation system. Vibration reduction measures for fans and motors are generally based on vibration reduction foundation, such as rubber vibration damper, spring vibration damper, etc. When the motor power of rotary blower is less than or equal to 75KW, it is not necessary to install the valve only for starting. When centrifugal boiler induced draft fan is selected to discharge high-temperature flue gas or air, the valve for starting shall be set to prevent overload caused by cold operation.
