General axis flow can be used for ventilation and ventilation of factories, warehouses, offices, houses and other places. It can also be used for air -cooler, evaporator, condenser, fog, etc., and can also be used for shaft flow.Anti -corrosion -proof shafts use anticorrosive materials and explosion -proof methods, and are equipped with explosion -proof motors, which can be used to transport explosive and volatile substances.In contemporary society, modern industries, construction and related real estate industries have developed agile, and the planning is expanding agile.In the construction of factories, warehouses, office, etc., one of the important links is the ventilation of buildings.At this moment, the anticorrosive shaft plays an important role.The anticorrosive shaft is directly driven by advanced predators and low noise exterior rotors or internal rotor motors.In addition, it is suitable for transporting flammable, explosive, and non -corrosive gases.
1. Pay attention to the wiring of explosion -proof shaft flowers:
1. Open the lid of the explosion -proof air motor motor wiring, and use a multimeter to confirm the motor winding without voltage
2. After the three -phase lead is marked, remove the power leader, short -circuit the three -phase lead on the power end, and wrap the connector with a white cloth to protect
3. Check whether the explosion -proof wind motor wiring box cover is sealed and the lead seal cover has aging cracks
4. Check whether the wiring box of the explosion -proof air motor machine is dry, clear the internal dirt inside the wiring box, and remove the oxidation layer in the wiring column
5. Check the phenomenon of not damaging, aging and other phenomena of the motor of the explosion -proof air motor motor
6. Use the Zheou table to measure the three relative ground and phase insulation resistance (only measure the opposite impact resistance when the three -phase current line is led from the motor wiring box) and the power cord to the ground insulation resistance: not less than 1MΩ, and recorded in the table in the table
7. Use a two -arm bridge to measure the three -phase dwarf resistance of the motor stator winding.The difference between the DC resistance of each phase winding must not exceed 4% of the smaller value
2. How to solve the efficiency of the processing of explosion -proof shaft flowers?
Explosion -proof is to be able to work properly when explosion -proof, and it can work normally when explosive danger. It can resist impact and heat resistance. Therefore, explosion -proof shaft flowers.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.
