Introduction of YBX3 Explosion - proof Motor 

YBX3 explosion-proof motor, also known as YBX3 flameproof three-phase asynchronous motor, is YB3 explosion-proof motor through technology research and development to develop a new generation of products, the motor has high efficiency, energy saving, high temperature margin, long life, good performance, low noise , Advanced explosion-proof structure, excellent starting performance, beautiful appearance, high reliability, the operation does not produce spark, easy to use and maintenance advantages. YBX3 explosion-proof motor efficiency indicators in line with GB18613-2012 "small and medium-sized three-phase asynchronous motor energy efficiency limit and energy efficiency rating" motor energy efficiency level 2 indicators, and IEC60034-30 IE3 link the same. Its power level and placement size in line with the IEC scale and with the YB2, YB3 series of motor similar to the export configuration equipment is conducive to the deployment of the use of equipment and the deployment of the original replacement replacement. This series of motors can also be made of wet tropical YBX3-TH, dry tropical YBX3-TA, outdoor YBX3-W and outdoor anti-moderate corruption YBX3-WF1, outdoor anti-corrosive YBX3-WF2 and outdoor hot and humid case YBX3- THW, outdoor dry and tropical type YBX3-TAW, tropical type YBX3-T, outdoor tropical type YBX3-TW, indoor anti-medium corrosion type YBX3-F1, indoor strong corrosion type YBX3-F2.

Ex d Ⅱ C T4 Gb is suitable for use in the IIC class of the factory, the temperature group for the T1, T2, T3 and T4 groups of explosive gas mixture exists in the environment. YBX3-TH outdoor hot and cold type, YBX3-TA dry and tropical type, YBX3-TA dry and tropical type, YBX3-TH wet and tropical type, YBX3-THW outdoor hot and humid type, T tropical type, YBX3-TW outdoor tropical type and YBX3-WF1 outdoor medium anti-corrosion type and other climatic environmental conditions. 3. Implementation of the standard YBX3 series of high efficiency flameproof three-phase asynchronous motor main implementation criteria are as follows: GB 755-2008 Rotating motor quota and performance GB / T 1032-2012 Three-phase asynchronous motor test method GB 3836.1-2010 Explosive environment Part 1 : General requirements for equipment GB 3836.2-2010 Explosive atmospheres - Part 2: Equipment protected by flameproof enclosure "d" GB / T 4942.1-2006 Degree of protection (IP code) for the overall enclosure structure of a rotating electrical machine GB 10068-2008 Shaft center height Measurement, evaluation and limits for mechanical vibration of motors of 56mm and above GB / T 10069.1-2006 Methods and limits for the determination of noise of rotating electrical machines - Part 1: Determination of noise of rotating electrical machines GB / T 18613-2012 Small and medium-sized three-phase asynchronous Motor energy efficiency limit and energy efficiency rating.

YBX3 explosion-proof motor is mainly used for what places?

YBX3 explosion-proof motor can be used for coal mine (non-mining face) fixed equipment or plant IIB level, due to YBX3 efficient explosion-proof motor must meet the explosion requirements, so a lot of explosion-proof grade, EXDI and EXDII two. EXDI is used for coal mine non-mining surface, the important gas is methane. EXDII is used in workshops where the ignition temperature group is a group of T1 to T4 flammable gases or explosive atmospheres formed by vapor and atmosphere. The temperature groups are T1-T4 groups of flammable gases or vapor and air to form explosive mixtures in places where the mechanical equipment of the drive motor is mainly used for coal, oil, natural, petrochemical and chemical industries. Explosion-proof motors are used as the main power equipment, usually used to drive pumps, fans, compressors, conveyors and other transmission machinery. In addition, in the textile, metallurgy, transportation, grain and oil processing, paper, medicine and other departments are also widely used.
