1, according to the drawings shown in the orientation and scale device, in order to get high efficiency, in particular to ensure that the inlet and impeller clearance scale to meet the request.
2, to ensure that the horizontal direction of the spindle, and measuring the concentricity of the spindle and the motor shaft and the coupling of the two sides of the imbalance. The error between the two axes is not 0.05mm, and the error of the two sides of the coupling is not 0.05mm.
3, the device conditioning door, pay attention not to install anti, to ensure that the direction of intake and impeller rotation direction common.
4, fan device, turn the rotor, see is too tight or fixed with some scratching phenomenon.
5, the device fan imports and out of the pipeline, the weight should not be added to the chassis, should be added to support.
6, after all the devices, the total view qualified, before trial run.
Fan work should pay attention to the following questions:
1, the fan test work should be no load (close the intake pipe gate or conditioning door) under the conditions.
2, such as working in good condition, and then transferred to full load (regular pressure and flow) work.
3, the new device fan full load work of not less than 2h, repair the fan not less than half an hour.
