Explosion -proof is to be able to work normally when explosion -proof. It can work normally when explosive danger. It can resist impact and heat resistance, so it is called explosion -proof shaft flow.Explosion -proof needs to be considered from three necessary conditions. One of the necessary conditions is limited, and the explosion will be limited.Select the corresponding explosion -proof instrument and explosion -proof electrical equipment.Standard structures are: explosion -proof, increased safety, positive pressure type, sand filling type, and oil supply type.
Based on the required air volume, voltage, speed, etc., Determine your fan type to select the model, choose a bearing fans with relatively low noise.Pay attention to the internal inspection of the shell when purchasing to prevent the tools or debris left.
Before installation, check whether the fan is damaged or deformed in detail.If so, install it after the correct restoration.
The base of the explosion -proof shaft fans needs to be naturally fitted with the basic plane. It is not allowed to knock the base forcibly connected to prevent the base from deforming.During installation, set the base for calibration, use iron pads and keep the horizontal position, and then tighten the foot bolt.Before installation, carefully check whether the explosion -proof shaft fans are damaged or deformed due to packaging and transportation, and then installed correctly after repairs.When installing, check whether the relevant parts are loose. The blade and the sliding pillow space should be uniform and not allowed to collide.The base of the explosion -proof shaft fans needs to be naturally fitted with the basic plane, and the bolt is not forcibly connected to prevent the base from deforming.During the installation, use the horizontal ruler to correct the base, keep the horizontal position, and then tighten the foot bolt.
Explosion -proof shaft flowers, exhaust volume and functional selection can be set on the operating panel to meet different operations in different places.Therefore, the function type of design schemes is also colorful and diverse, reaching different main use regulations, so that we can see that it will be more unusual in the characteristics of the design plan.Everything is effective to strictly control the setting of settings, or it will have different functions.
(2) What are the advantages of explosion -proof shaft flow fans?
Explosion -proof shaft fans:
I. Overview of explosion-proof shaft ventilation ventilation ventilation-proof shaft flow ventilation is a new type of fan that improved the design based on the BT30-11 in the 1980s. It has obvious advantages compared to the BT30-11 fan:
1. The performance is greatly improved, and the full pressure effect is 89.5%;
2. The structure is more reasonable;
3. Low noise, noise (more than A) decrease 3.6db (A).Explosion -proof shaft ventilator is applicable and transported flammable and explosive non -corrosive gases. The environmental temperature must not exceed 60 ° C. It is widely used in general factories, warehouses, offices, residential ventilation, ventilation and air heat dissipation.Inside the exhaust pipes are installed in series to improve the pressure in the pipeline, the motor can be used as a free fan.The anticorrosive shaft fans (FT35-11) are processed by the anticorrosive material coating, and the motor uses a special anticorrosive motor to transport corrosive gases.Explosion-proof shaft fans (BT35-11) are used to transport flammable and explosive gases.The leaf wheels are processed by aluminum alloy to prevent sparks in operation. The motor uses explosion -type motors.The performance parameters of the FT35-11 and the BT35-11 fan are the same as the T35-11 fan.The fan needs to bring a bracket foot and motor voltage.
2. Explosion -proof shaft ventilation explanation
1. The air vent on the wind turbine must be installed and hopes to install the protective net.
2. Pay attention to check whether the connection parts are loose during installation. The gap between the blades and the air cylinder should be uniform and must not touch each other.
3. The weight of connecting the air outlet pipe should not be bear by the fan of the fan, and the supporting frame should be added during installation.
4. Check whether the fan should be damaged and deformation before installation. If it is damaged and deforms, it can be installed after being repaired properly.
5. After the installation is completed, the experiment must be performed first. After the operation is normal, it is allowed to be formally used.Technical parameter explosion -proof logo: EEDIIBT4 protection level: IP54 anticorrosive grade: WF1 rated
