DFBZ/XBDZ-I-4.0 low-noise square wall axial flow fan

DFBZ/XBDZ-I-4.0 low-noise square wall axial flow fan ，Adopting efficient and low-noise axial flow impeller, fan specific motor direct drive, and square soundproof housing (can further reduce fan noise; the whole machine is made into a square shape, with simple reserved square holes on the wall and easy installation). The air outlet is equipped with aluminum alloy self hanging louvers (which can prevent outdoor rainwater, dust, and natural wind from flowing into the indoor area); It has obvious advantages such as beautiful appearance, low noise, smooth operation, and firm installation, and is widely used for low-noise wall exhaust in civil and commercial construction projects and workshops of factories and mines. Explosion proof and anti-corrosion fans can be made according to the requirements of the usage scenario.

This series of fans is generally equipped with three-phase motors, which can be customized according to user requirementsUse single-phase motor below 0.55kW

DFBZ/XBDZ-I-4.0 low-noise square wall axial flow fan，Axial flow fan is mainly composed of impeller, casing, motor and other components, and the bracket is connected to the casing and air duct using steel. The impeller and casing of the anti-corrosion axial flow fan are made of fiberglass, while other types of axial flow fans are generally made of steel plates.

working principle

When the impeller rotates, gas enters the impeller axially from the inlet and is pushed by the blades on the impeller, causing the energy of the gas to increase, and then flows into the guide vanes. The guide vanes convert the deflected gas flow into axial flow, while introducing the gas into the diffuser, further converting the kinetic energy of the gas into pressure energy and introducing it into the working pipeline.

The working mode of axial flow fan blades is similar to that of aircraft wings. However, the latter applies lift upwards to the wings and supports the weight of the aircraft, while axial flow fans fix their position and move the air.

The cross-section of an axial flow fan is generally a wing section. The blades can be fixed in position or rotated around their longitudinal axis. The angle or spacing between the blades and the airflow can be either non adjustable or adjustable. Changing the blade angle or spacing is one of the main advantages of axial flow fans. The angle between leaflets produces lower flow rates, while increasing the spacing can produce higher flow rates.

*Axial flow fans can change the blade spacing during fan operation(This is quite similar to a helicopter rotor), thus changing the flow rate accordingly. This is called a Variable Vane (VP) axial flow fan.

Application scenarios

Can be used for ventilation and heat dissipation in places such as metallurgy, chemical industry, light industry, food, pharmaceutical equipment, mechanical equipment, and civil buildingsIf the casing is removed, it can also be used as a free fan or installed in series at intervals in longer exhaust ducts to increase the air pressure in the ducts.

Characteristics of axial flow fan:

Small axial flow fanLow power consumption, fast heat dissipation, low noise, energy-saving and environmentally friendly. Due to its small size, it has a wide range of applications.

Large axial flow fans have the characteristics of simple structure, stability and reliability, low noise, large air volume, and wide functional selection range.

BSJG-3.5F Explosion proof diagonal flow duct fan

The diagonal flow fan is divided into cylindrical diagonal flow fans（GXF type and drum type diagonal flow fan (SJG type), GXF type fan is a medium pressure duct fan,

ButSJG type diagonal flow fan has higher air pressure.

The flow rate of a diagonal fan is greater than that of a centrifugal fan

Machine, with a total pressure higher than axial flow fan and a volume smaller than centrifugal fan.The SJG series diagonal flow fan is a component of the SWF series fan

Derivative product, using drum shaped air duct to adjust airflow direction Thus achieving the effect of recovering static pressure, improving wind pressure and efficiency.

BSJG-3.5F Explosion proof diagonal flow duct fanCan be used for general ventilation and air exchange, with the following usage conditions:

1. Application site: As an indoor ventilation system for general factories and buildings, it can be used as both an input gas and an exhaust gas.

2. Types of gas transported: air and other non flammable gases, harmless to human body and non corrosive to steel.

3. Impurities in gas: Viscous substances are not allowed in the gas, and the dust and hard particles contained should not exceed 150mg/m3.

4. According to the special needs of users, magnetic motor transmission can also be designed to achieve stepless variable speed and variable air volume structure.

5. Gas temperature: not exceeding 60 ℃.
