Do you have a good command of DC Blower?

DC blowers fan offers maximum reliability and superior cooling with frame sizes ranging from 20 mm to 160 mm and air flows up to 250 CFM. All models can with auto restart protection and feature ball bearing, hydraulic bearing, sleeve bearing that provides a unique alternative to traditional sleeve bearing designs. With a variety of additional options, these DC blower fans are the ideal forced air cooling solution for the user's application.

What are the components of a DC blower?

The DC blower is mainly composed of six parts: motor, air filter, blower body, air chamber, base, and drip nozzle. The blower operates eccentrically on the rotor offset in the cylinder and changes the volume between the blades in the rotor slot to suck in, compress, and discharge air. During operation, the pressure difference of the blower is used to automatically send the lubrication to the drip nozzle, and drip into the cylinder to reduce friction and noise, and at the same time, it can keep the gas in the cylinder from returning.

What are the advantages of DC blowers?

1. Since the impeller runs frictionlessly in the body and does not require lubrication, the discharged gas does not contain oil. For chemical, food, and other industries, DC blowers can be used to convey air.

2. The structure of the DC blower determines that its mechanical friction loss is very small. Because only the bearing and gear pair have mechanical contact on the material selection, the rotor, casing, and gear ring have sufficient mechanical strength. Operational safety and long service life are major features of blower products.

3. The rotor of the DC blower has been checked for static and dynamic balance. The finished product runs smoothly with little vibration.

The discharge electrode of the DC blower does not need a grounding electrode, and the discharge electrode is composed of separate discharge needles for positive and negative. When there is no external air supply (such as a fan, compressed gas, etc.), the DC static elimination distance is longer than the AC type static elimination. In the case of external wind, the elimination distance mainly depends on the static elimination equipment. The structure, the air volume, and the strength of the high-voltage power supply. Since the discharge needle will be contaminated after long-term use, it will directly affect the static elimination performance and ion balance. Therefore, the static elimination electrode part should be cleaned regularly during use, especially since the DC blower discharge needle is easy to be contaminated, and the positive and negative discharge needles The degree of wear is different, and regular ion level testing is required. When the wear of the discharge needle is severe, the discharge needle should be replaced in time.
