The YWG high-speed self-lubricating and explosion-proof motor, the largest power in China, has been successfully developed by Shanghai Electric Group Shanghai Electric Machinery Factory Co., Ltd., which is designed and manufactured in compliance with GB755 "Ratings and Performance of Rotating Electric Machines", GB 3836.1 "Electrical Equipment for Explosive Gas Atmospheres-Part 1: General Requirements", GB 3836.8 "Electrical Equipment for Explosive Gas Atmospheres-Part 8:"n" Type Electrical Equipment "and other relevant standards. This motor product: 1. It is the largest power of similar motors in China at present, and its technical level has reached the domestic leading and international advanced; 2. After theoretical calculation and comparison, more reasonable self-lubricating end-cover sliding bearings and lubricating oils are selected to ensure reliable bearing temperature rise; 3. The stator windings adopt low-glue insulation system and VPI vacuum pressure impregnation technology; 4. Through reasonable structural design and complete mechanical calculation, the reasonable critical speed of the rotor is controlled, the vibration of the motor is effectively controlled, and the safe operation of each mechanical component is ensured; 5. Through reasonable electromagnetic design and rotor ventilation system and internal and external air path design, and Take noise reduction measures to effectively reduce motor noise. 6. Apply for the following seven patents (including patent applications) for technical preparation and design and manufacturing process: "Brazing Process for End Rings and Guide Bars of Motor Rotor Using Low-Silver Solder"(Patent Application No. 200710172006.7)"Motor Rotor and Stator Core Pressing Machine"(Patent No. 200820150645.3),"Auxiliary junction box for flameproof motors"(Patent No. 200820056392.3),"Manufacturing Method of Cable Connectors for Flameproof Motors"(Patent Application No. 200810034898.9),"Connecting Structure for Auxiliary Component Leads on Flame-Proof Motors"(Patent Application No. 200810034896.x),"Stator Punching Sheet Sizing and Slot Die"(Patent Application No. 200910057099.8),"Method for Punching Set Members and Rotor Punching Sheet"(Patent Application No. 200910057100.7). 7. The on-site industrial operation results show that the overall performance of the motor fully reaches the level of imported products, among which the motor noise value is about 10dB lower than the national standard limit, and the maximum motor vibration value is 1.0 mm/s, which is far lower than the national standard limit (2.8 mm/s), both superior to similar imported motors on site. The YWG high-speed self-lubricating non-spark three-phase asynchronous motor adopts self-lubricating bearings and a fully enclosed air-air cooling method, eliminating a series of additional costs and pollution problems caused by conventional forced lubricating oil stations and water supply, air supply and cooling systems. It is widely used in explosive hazardous locations in Zone 2 of the factory, especially in harsh environments such as offshore oil production, oil and gas pipeline transportation, and can withstand wind, sun, rain, low temperature, The test of various complex environmental conditions such as high altitude. It has certain advantages in production and use, especially in terms of economy. It is efficient, energy-saving, low-noise and environmentally friendly, and has high cost performance and market value. Its comprehensive performance has reached the international advanced level, which will make up for the technical gap of this type of motor in China, break the monopoly of imported products, enhance the domestic and international competitiveness of the "Shanghai Electric" brand and electrified explosion-proof motors, and promote the localization process of equipment for major national projects, especially explosion-proof electrical equipment, and can enter the international market, creating greater economic and social benefits for enterprises and users. At the same time, the design, process, manufacturing, inspection and quality assurance systems of Shanghai Electric Group Shanghai Electric Machinery Factory Co., Ltd. can meet the requirements of mass production of products. At present, the motor of this project has been operating safely and stably in the Tieling Oil Pipeline Pump Station of the Tieqin Line for nearly 10,000 hours. Due to the successful development of this project, the company subsequently undertook and successfully completed pipeline oil transportation projects such as the Shilan Line and the Zhongyin Line, which also served as the follow-up Qing-Railway The fourth-line and the Yidong-line projects have seized huge advantages. With the development of my country's oil, natural gas and other industries, the future market share is expected to reach 200 million yuan.
