Introduction to the characteristics of paper-size explosion-proof motor equipment
Paper size explosion-proof motor, also known as paper size explosion-proof three-phase asynchronous motor, is a new
Generation of products developed through technical research and the development of paper-size explosion-proof motors. The motor has high efficiency, energy saving, large temperature rise margin, long life and good performance, low noise, advanced explosion-proof structure, excellent starting performance, beautiful appearance, high reliability, no electric sparks during operation, and convenient use and maintenance. The efficiency index of paper size explosion-proof motor conforms to the energy efficiency limit value and energy efficiency level of small and medium-sized three-phase asynchronous motors in paper size and is equivalent to the paper size of paper size. Its power level and installation size conform to the paper size standard and are the same as the paper size series motors, which is conducive to the matching application of export equipment and the replacement of original equipment. This series of motors can also be made into YBX3-TH for humid tropics, YBX3-MT for dry tropics, YBX3-W for the outdoors, YBX3-WF1 for outdoor moderate corrosion, YBX3-WF2 for outdoor strong corrosion and YBX3- THW, outdoor dry tropical type YBX3-TaW, tropical type YBX3-T, outdoor tropical type YBX3-TW, indoor anti-moderate corrosion type YBX3-F1, indoor
anti-strong corrosion type YBX3-F2.

Based on the paper size basic series motors, it can also be made into YBX3-W outdoor type, YBX3-TH humid tropical type, YBX3-THW outdoor humid tropical type, YBX3-T dry tropical type, YBX3-TaW outdoor dry tropical type, YBX3 -T tropical type, YBX3-TW outdoor tropical type and YBX3-WF1 outdoor medium anti-corrosion type and other climate and environmental conditions. paper size implementation standard paper size series high-efficiency flameproof three-phase asynchronous motor main implementation standards are as follows: MB 585-2008 Rating and performance of rotating electrical machines MB/T 1032-2012 test methods for three-phase asynchronous motors MB 3834.1-2010 explosive atmosphere paper Part size: General requirements for equipment MB 3834.2-2010 Explosive atmospheres Part 2: Equipment protected by flameproof enclosure paper size MB/T 49.1-2006 Degree of protection for the overall enclosure structure of rotating electrical machines (the copy) code) classification input method 10068- 2008 Measurement, evaluation, and limit value of mechanical vibration of the motor with shaft center height of 56mm and above MB/T 1009.1-2006 Noise measurement method and the limit value of rotating electrical machine Part of paper size: Noise measurement method of rotating electrical machine MB/T 18913-2012 Energy efficiency limit value and energy efficiency grade of small three-phase asynchronous motor
Where are paper-size explosion-proof motors mainly used?
Paper-size explosion-proof motors can be used in a coal mine (the copy) non-excavation face) fixed equipment or factory IIB level, because paper size high-efficiency explosion-proof motors must meet the explosion-proof requirements, so there are many explosion-proof grades, there are two kinds of EXDIR and EXDII. The one with EXDIR is used in the non-mining face of the coal mine, and the main gas is methane. EXDII is used in the workplace where there is an explosive mixture formed by flammable gas or vapor with an ignition temperature group of T1-T4 group. The driving motor of mechanical equipment in the place where the temperature group is an explosive mixture of flammable gas or vapor and air in the T1-T4 group is mainly used in coal mines, petroleum, natural gas, petrochemical, and chemical industries. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors, conveyors, and other transmission machinery. In addition, it is also widely used in textile, metallurgy, transportation, grain and oil processing, papermaking, medicine, and other departments.

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.
