Centrifugal Blower Airflow Device Ventilator Electric Foot Dual Axial Centrifugal Fan
The DJF-1 Electric Pedal Dual-use Fan is designed to handle large volumes of air when the power supply is cut off in the war in the basement.It can be used filter-type ventilation system when suffering atomic, chemical, or bacterial cases.
This centrifugal fans use blades to extract gasses and air at right angles while spinning the air outwards radially. As a result, centrifugal fans can operate effectively in environments that have both extreme temperatures and high pressure, providing a stronger and more stable airflow when compared with axial fans.
The focus of the technical indicators is to ensure that the 400-person unit filter-type ventilation system in wartime human-driven situations.In peachtime,this unit can work for ventilation in basement,Restaurant,shopping mall and so on.It can be used as filtration and drying systems,ventilate and exhaust systems, air pollution control (clean side of dust collectors) and other industrial processes.
The DJF-1 is constructed with centrifugal fan and incorporates hollow airfoil blades for higher efficiencies and better sound quality. All housings are reinforced with rigid bracing to increase structural integrity. The support angles are intermittently welded and caulked between welds to prevent bleed-through corrosion.And it also contains human-driven application to ensure this system can work normally when the power supply is cut off
The centrifugal fans are a type of fan that uses centrifugal force to create a pressure increase and a volume flow.
This type consists of a fan wheel that rotates in a snail-shaped cover.
The flow enters the fan through an inlet placed axially with the fan wheel shaft and motor, and is then thrown out radially with the help of the force from the fan wheel.
Unlike axial fans, the motor is not in the volume flow of radial fans.
To change the performance and characteristics of centrifugal fans, different designs are used on the fan wheel.
The strength of the centrifugal fan is its versatility. A centrifugal fan can be designed to transport a variety of volume flows at a wide range of pressures.
At higher flows and relatively low pressures, an axial fan may be a better option.
Centrifugal fans are available in single and double suction versions.
Centrifugal fans can be connected in series in two or more stages, this gives acceptable sound levels even at very high pressures.
A centrifugal fan usually has a higher overall efficiency than an axial fan.
The flow of centrifugal fans is mainly regulated with speed control, it is also not unusual for centrifugal fans to run towards a fixed operating point.
As an alternative, the flow can also be regulated with dampers that have variable opening. A third option is through a guide rail device that creates a co-rotation of the volume flow before the fan.To choose the right centrifugal fan, you should start from the area of use, how the fan is to be controlled and whether there are any special requirements.

The Application Scenarios
Notes
Normally this fan works by electric drive,only use Human-driven in the war.Once using Human-driven,it must be in emergency situation,so we must ensure the equipment is always in a normal working condition.At ordinary times
to strengthen the maintenance, especially the sports part.
1,Check the gearbox for oil leakage and oil seepage, and replace the sealing gasket if necessary
2,For the chain, tooth disc and flywheel to regularly add lubricating oil, do not rust
3.Check the partial structure of the support for rust damage and lost fasteners
4.Gearbox maintenance: Open the gearbox to check the lubricating oil;then add a new 120 gasoline if the oil amount is insufficient, ensure the oil plane flush with the lower surface of the shaft.
Then one person runs slowly and check for phase rubbing or crash sound.
If there is no mechanical faults, the four people should operate for 5 minutes at the same time. If there is any fault, the parts should be repaired or replaced in time
5.If the fan is not used for a long time, the belt should be removed, or the motor base is loosened, so that the belt is thrown loose. The above maintenance work should be carried out once a quarter, and once in one or two month in hot and humid days
- This centrifugal fans are designed for a wide range of air volumes and pressures. With backward inclined, backward curved, backward inclined airfoil, radial and forward curved impeller types, centrifugal fans offer the flexibility to match the performance and application at the highest efficiency. Most models are available in single-w
- ide or double-wide configurations that allow for even higher volumes of air.
- The construction allows for the maximum compactness of fans, excellent motor cooling, low noise levels and high energy efficiency.
- The fans are designed and produced in line with clients' specific requirements and comply with all provisions of current regulations and directives concerning the environmental design of fans.
-
- Technologies
- We direct major investments into key technologies to ensure energy efficiency, robustness and especially the consistent qualities of the fans.
- Modern technologies of winding, forming and impregnating stator windings ensure the fans' long life. And the technologies of the final assembly of fans and the mechanical balancing of the rotor stack with the propeller of the fan give excellent vibro-acoustic characteristics.
- All key machining operations on components and sub-assemblies of fans are quality-controlled. In the case of the most complex fans with integrated electronic drives, the process parameters together with the testing parameters.
- If a client specially wishes, the fan's appropriateness can also be confirmed by measurements of the aerodynamic and vibro-sound characteristics and its functionality by testing its thermal sustainability.
- Areas Of Product Application
This fan is designed to supply and exhaust air in hospitals, hotels, schools, fume hoods and similar environments.These units are used in the most complex energy efficient heating, ventilation, air conditioning and cooling systems. With its competencies in planning, sample production and lab testing, the application development team ensures a quick response and the adapted construction and functioning of centrifugal fans in line with clients' needs or specifications.
