KAILONG brand low-noise transformer fans are characterized by low noise and energy-saving.It is specially in the cooling system of middle and big-sized transformers.It is designed and manufactured by Taizhou Tongda Electromechanics Co.,Ltd in accordance with the industrial standard of JB/T9642-1999(transformer fans)and others.It has been approved in the provincial check participated by state authoritative persons.The product,with merits of low noise,high efficiency,stable performance,long service life.Suitable for transformer cooling system or with the transformer with the radiator, is the present advanced low noise, performance, high efficiency of transformer cooling system dedicated fan, and also can match for all kinds of conditions need to run using ventilated environment.

1.Products description

2.The fan structure


3.Choose
1, fan using conditions;
Fan - using the environment temperature of 40 ℃ ~ 75 ℃, height is not more than 1000 meters above sea level, the relative humidity of 95%, the sun wheel
Maximum intensity of 0.98 kw / ㎡, the maximum rainfall intensity 50 mm / 10 min, by gas blower are not allowed to have a strong acid, strong alkali,
Halogenated hengjing, ketones, aldehydes and other corrosive gases.
2, Fan selection principle：
1 /, fan of geometry features:The diameter of the fan, namely;Tip of the blade row by the diameter of the circle, axial flow fan is the most important parameters, the geometry characteristic of the calculated diameter size can be selected;Usually with the flow, total pressure, leaf number, speed, medium density and so on, the diameter size directly affect the aerodynamic performance and structure size of the fan.
2 /, Fan movement characteristics:Determine the axial flow fan air flow axial movement and the parameters of the rotary motion is the movement characteristics of axial flow fan, axis
Flow fan according to the aerodynamic design and calculation of parameters to determine the level through the fan air flow velocity and direction.
3 /,The dynamic performance of the Fan:The dynamic performance of the axial flow fan system parameters such as flow rate, air pressure, power, efficiency, these parameters are generally based on fan production factory to provide product technical parameter table, namely axial flow fan performance parameters, as the main basis when choosing axial flow fan.
