The noise from radiator fan of supply is vexed questions. If you want to lower the noise but have no better way. And there is good skill that how to lower noise from radiator fan of power supply for yours from S&T .

1. Clean the dust of the surface of radiator fan : At first ,prepare a piece of toothpick and a little of lubricant oil. Then disassembly the power supply and open its case, and take out the radiator fan . you can find the location of dust accumulated ,so you can clean them. And usually, it will be appeared a label of brand which be stuck with the center of radiator fan. Now you can find a bearing when you reveal the label. And then take proper lubricant oil and drop it into bearing and recover the label, and reinstall them. You must be careful not to use the inferior oil. Because they will enhance scuffing for the bearing.

2.Change the mute radiator fan of power supply: User maybe consider to use the mute power supply or change the fan. So far ,there are lots of mute power supplies in market, and they are all be inspected and tested strictly. So you can lower noise of power supply effectively. Certainly you can select the better radiator fan for the power supply. It is simple to change the radiator fan of power supply, but you must keep your eyes peeled to the part access of connect both the power supply and the radiator fan. 3.Cushion and avoid vibration: For the power supply, the position of the shock proof is not only between the radiator fan and power supply, but also between the power supply and the case. Except for being fixed firmly. You can also use the material just as strips of fabric and cushions to avoid vibration.

4.Avoid the strong current surge: sometimes the bigger noise from the blink that you switch on the power supply and there is strong current surge to occur. You can install a filter or change a better power supply.

The mini DC blower be used in many fields. But what characters do these mini fan
have? .

1.The friction of fan is a bit smaller, because of there is only mechanical touch between the bearing and the wheel gear. For the material of selecting, they all have enough intensity just as rotor, case and the cycle of wheel gear. They can run safety and longval.

2.For the structure, there is no friction of impeller inside of the body. And the air of draining without oil. It is a ideal air-pressure source for Chemical industry and Food industry.

3.The air flow is very smaller by the various air pressure when we use it. But the air flow changes with the speed. Therefore, it is wide range for selecting of air pressure. And meet your required of the different air flow through the various speed.

4.The DC blower is higher speed. The gap between the rotor and rotor, or between the rotor and the body is a bit. So there is little leakage, volume rate are higher. The technism strength for the handling and assembling. So it can guaranteed the gap of them to be proper and well-distributed, and get higher effective of volume rate. Furthermore, it is can’t occur friction by the expansions of body when they be heated.

The air flow into the impeller through the air intake,. The impeller be pushed by air pressure, to cause the air pressure increase and be transfer into guide blade. The guide blade will change the deflection flow to axial flow. And then push the air-flow into the diffuser, furthermore, the air-flow energy can be converted to pressure energy, at last, this energy can be transfer to blast pipe of requirement.

The running method of impeller of axial-flow fan is same as the wing of plane. But there is different of them. For the wing of plane, the rose force of rotated impeller will bearing the weight of plane and lift up them. But the impeller of axial-flow fan is fixed and it can move the air to flow.

The axial-flow fan is always used in the industrial and mining enterprise. But it is different from others, its rotator and blade is installed inside barrel. It is used to ventilate air and easy to install. It is convenience to use. The effective of air changing is obvious and can directly send the air flow to the place of requirement.

It is very easy for operating the DC blower . Of cause, it will be breakdown if you don’t maintenance it correctly. And how to maintain it ? So there are some points you need to notice for below:

1. For the place of assembling, we suggest it is indoor and avoid wind.

2. For the temperature of assembling, we suggest it is not high and keep it under 40 ℃.

3. For the humidity of running, we suggest its under 80 ℃.

4. For the atmosphere will be kept well, it can not involve the corrosive gases;

5. We suggest don’t running in the circumstance with lots dust. If you have to run it ,you can install a filter and time maintenance for it.

1. The structure of centrifugal fan is more complex than axial-flow fan.

2. The direct of medium in blast pipe be changed. But it not be changed about axial-flow fan.

3. The connection is different ,the centrifugal fan connect by axial and the axial-flow be installed internal of it;

4. The place of installing is different, the centrifugal fan be installed on the gate of air outlet or of air intake. Just as air condition. But the axial-flow fan always be installed inside of blast pipe.
