Product Description

YBBP Series Flamepreview Variable- fraction Adjust-speed Indication Motors


Overview  

The paper-size explosion-proof frequency conversion speed regulation three-phase asynchronous motor is a new product successfully developed on the basis of the paper-size series motors and combined with the current domestic and foreign new technologies in electromagnetic structure, technology, materials, etc. It has good speed regulation performance, Energy saving, large temperature rise margin, long life, good performance, low noise, advanced explosion-proof structure, high reliability, convenient use, and maintenance, etc., and can be used with various frequency conversion devices at home and abroad, which is helpful for energy saving and automatic control. Its rated power rated speed and installation size are the same as the paper-size series motors.  


This series of motors comply with the paper size "rotating motor rating and performance" industry standard paper size series variable frequency speed regulation three-phase asynchronous motor (the copy) frame size 80 +345[]] and its explosion-proof performance complies with paper size Explosive atmospheres Part paper size: Equipment General Requirements" and paper size Explosive Atmospheres Part 2: Equipment Protected by Flameproof Enclosures Paper Size", respectively made of flameproof ExdIMb, ExdIIBT4G b, ExdIIBT4G b, suitable for coal mine underground (the copy) non-excavation work Surface) and factory IIB, IIB level, temperature group paper size group in the hazardous area of explosive gas atmosphere.  
The enclosure protection grade of this series of motors is IP or paper size, and the cooling method is Ic433.  
This series of motors can also be made into humid tropics type, dry tropics type, outdoor type, outdoor medium anti-corrosion type, and outdoor damp heat type.  


2. Structure Description  
The paper-size explosion-proof frequency conversion speed regulation three-phase asynchronous motor adopts a computer-aided design so that the motor can adapt to the situation of SPWBM and paper-size variable frequency power supply. To obtain a more appropriate inductance value, suppress and reduce the adverse effects of harmonics.  
The electromagnetic load design of the motor takes into account a certain margin, which can not only ensure the overload capacity of the motor at high frequency but also maintain constant torque output at low-frequency operation. In addition, the motor insulation system adopts the 6-level insulation system widely used in the world, with reliable insulation and excellent performance. In terms of structural design, its installation size is the same as that of paper-size series motors, which is convenient for users to use together.  
The motor adopts a separate axial flow fan for forced ventilation to ensure that the motor has a good cooling effect when running at different speeds.  
3. Conditions of use  
Altitude: suitable for altitudes not exceeding paper-size meters  
Ambient air temperature: work in an environment where the ambient air minimum - of 15% does not exceed the paper size.  
The maximum relative humidity of the ambient air does not exceed 9% (when the temperature is the paper size (the copy) coal mine underground) or the monthly average relative humidity of the wettest month is 80%, and the monthly average minimum temperature of the month is not higher than 25% (factory).  
Rated voltage: 380/650V, 650/740V  
Nominal frequency: 500 Hz  
Working mode: continuous working system 1" (msg. "12:34 am)  

Frequency modulation range: 2-pole frequency modulation range paper size above pole is 3(5) constant torque speed regulation, 50%100Hz constant power speed regulation.

Our Advantages

 

 

Strict quality standards, precision machining, and other spare parts and design maintain product stability, strictly select product parts suppliers, and perfect after-sales service system to allow customers to enjoy a new experience

Our company has introduced the latest research results of the Chinese Academy of Sciences, C4-II ternary flow wing twisted blades, which have high aerodynamic efficiency.
The surface of the ventilator impeller blade is sprayed with advanced super-resistant (CN) metal material to form a wear-resistant, anti-corrosion protection layer on the surface of the blade. The wear resistance of the blade surface is 10 to 50 times higher than that of the ordinary carbon steel material, thereby greatly prolonging the service life of the blade.

After we have absorbed the advantages of many domestic blade structures, based on the optimal control theory of concentrated parameters and distributed parameters, adopting the advanced ternary flow theory of impeller machinery and perfect CAD design technology, through multi-parameter control by blade bending amount, this blade is a high-performance fan blade. It ensures that the ventilator is operating in a wide and efficient area on the premise of meeting the wind volume and wind pressure.

Our company adopts computer simulation calculation and quasi-ternary flow theory, we correct the blade shape and calculate coordinate parameters of its shape, then make the core mold and the external pressure mold of the blade, and the blades are formed by hot pressing. According to a large number of experiments, the tilting blade has a larger lift-to-drag ratio than the original organic blade type and is the best choice for the airfoil blade.

The blades are welded with high-strength carbon steel material. The petiole is treated with high-quality carbon steel. So that the blade maintains the strength and rigidity of the steel blade when ensuring the corrosion resistance and wear resistance of the blade. Moreover, it effectively protects the blade from corrosion resistance and wear resistance in a humid air environment, and improves the operating life of the ventilator.

The surface of the blade is coated with a super-resistant (CN) metal material coating, which not only maintains the strength and rigidity of the high-quality carbon steel blade, but also effectively protects the blade from corrosion resistance and wear resistance in a humid air environment, and improves the operating life of the ventilator.

The petiole is forged and made of high-quality medium carbon steel, and the tempering heat treatment is performed. The root has enough transition arc to eliminate stress concentration, through reasonable and correct force analysis and calculation, the strength, and safety factor of the most dangerous section of the blade root is more than 6 times. And carry out 100% X-ray non-destructive testing for welding seams of the blade root section and the blade, and all the defects were eliminated. Therefore, the impeller has a high degree of operational safety. Since the supply of the ventilator produced by our company, there has never been an accident of the petiole breaking and flying blades.

The impeller hub is made of high-quality steel and then tempered to process heat treatment. The surface of the hub is processed into a spherical shape, the petiole hole is placed at the thickest part of the center of the rim, which reduces the friction loss of the wind flow and ensures that the force-bearing section of the hub has sufficient tensile strength and rigidity. The welded joints of the hub all adopt groove welding and carry out 100% X-ray non-destructive testing for welding seam, which ensures the safe operation of the impeller.

After the blade is formed, first sandblasting is performed to remove dirt on the surface of the blade such as welding slag and oxide layer, to show the original color of the metal; Then, using the latest international inverter pulse arc power supply and high-speed arc spray gun to paint the super-resistant (CN) metal material on the surface of the blade, to form a wear-resistant anti-corrosion protection layer on the surface of the blade. Compared with the traditional arc spraying equipment and spraying process, the coating is denser, the ultra-resistant (CN) metal material has higher bonding strength with the blade's basic body, and the service life is longer.
 

 

Quality assurance measures:

In long-term production management, our company has formed a set of standardized process control measures and control points, which can provide users with high-quality products in all directions. Our company has a good reputation and is an enterprise that users can absolutely trust.

Our company has obtained the IS09001 certification from the International Organization for Standardization (see Enterprise Qualification Materials for details). We strictly standardize the operation process and control points of product manufacturing
