Environmental protection steel explosion -proof shaft flow is a specially designed ventilation equipment that is mainly used for places with explosive dangers, such as petroleum, chemical industry, coal mines and other industries.This is a special design to prevent sparks or high temperatures during operation, thereby avoiding explosive accidents that may trigger.
Environmental steel explosion -proof shaft flowers are usually composed of explosion -proof motors, blades, air cylinders and other components. Among them, the impeller is processed by aluminum alloy, and the motor is an explosion -type motor to ensure the safety and reliability of the equipment.The fan is suitable for transporting flammable and explosive non -corrosive gases, and can work normally in environments with a temperature of no more than 60 ° C.
The working principle of the steel explosion -proof shaft fans is based on the basic design of the axis flow fan, and the consideration of explosion -proof characteristics is added.The following is the detailed working principle description:
Basic principle of axis flow fan:
When the motor of the axis flowers starts, the drivers impeller (also known as a rotor) rotates.
Gas (air) enters the impeller from the air inlet axis of the fan.
The blades on the impeller promote the gas to make it a certain energy (mainly kinetic energy).
When the gas is conducted, the guide leaf transforms the flow direction of the gas from the radial direction to axis, and the gas is imported from the voltage.
In the transverse tube, the kinetic energy of the gas is transformed into pressure energy, thereby increasing the pressure of the gas.
Finally, the gas is guided to the working pipeline or a specific area.
Explosion -proof characteristics:
Steel explosion -proof shaft fans specially considered explosion -proof requirements during design.This usually includes a special explosion -proof motor and an explosion -proof designs.
When explosion -proof motors can prevent sparks or heat from being transmitted to the external environment when sparks or short circuits inside the motor, thereby avoiding possible explosive risks.
The shell of explosion -proof design can resist the pressure fluctuations and explosion shock waves of the external environment, ensuring that the fan can still work normally or maintain the structure of the structure normally in the explosive environment.
In some special circumstances, explosion -proof shaft flowers may also be equipped with inert gas filling or special sealing measures to reduce the interaction of internal and external environments, thereby reducing the risk of explosion.
Application and characteristics:
Steel explosion -proof shaft flowers are usually used in the industrial environment of flammable and explosive gas or dust, such as petroleum, chemical industry, coal mines and other industries.
They not only have the function of ventilation, but also quickly eliminate the concentration of harmful gases or reduce the concentration of explosive gases in emergency situations, thereby reducing the possibility of accidents.
In addition, due to the use of explosion -proof design, these fans are relatively safe when running, and can run stably in harsh environments to ensure production safety.
In summary, the working principle of the steel explosion -proof shaft fans is mainly based on the basic design of the axis flow fan, and the consideration of explosion -proof characteristics is added to make it safe, effectiveEarth operation.
