Axial flow
When the leaves are rotated, the gas enters the impeller from the axial direction of the airway, driven by the blades on the impeller, so that the energy of the gas will be increased, and then enter the guide leaves.The guide leaf transforms the deflection air into axial flow. At the same time, the gas is imported into the voltage, which further converts the kinetic energy of the gas into a pressure energy, and then introduces the working pipe.The working method of a shaft -flow ventilator blade is similar to the wing of the aircraft.However, the latter uses the upward force to the wing and supports the weight of the aircraft, while the axial flow ventilator is fixed and the air moves.The cross section of the axial flow ventilator is usually a wing section.The leaves can be fixed in place or rotating the longitudinal axis around.The angle between the blade and the airflow or the distance between the blades is not adjustable or adjustable.Change the blade angle or spacing is one of the main advantages of the axial flow exhaust fan.The distance between the small leaves generates lower the flow, and the increase can generate higher traffic.
Common faults in shaft flow ventilator
1. Shaft -flow ventilator shaft shaft vibration;
2. Detect whether the leaf rotation heart is bent in the axis of the shaft flow ventilator;
3. Treatment of the replacement shaft heart and re -control the balance basis of the operating standards;
4. Check whether the entrance clock and the impeller are worn;
5. The processing entrance clock also moves backwards;
6. The axial axial stream exhaust device checks whether the axis is shifted or grinded between the axis;
7. Process adjustment of the axis streaming exhaust fan motor or replace the axis;
8. Check whether there are too many impeller crystal crystals;
9. Treat the crystals on the cleaning leaves;
10. Check whether the impeller is deformed or whether the blade is bent;
