[News] JASUNG has obtained the world's first 315KW permanent magnet direct drive drum explosion-proof certification, leading the belt drive system slimming revolution

[News] JASUNG has obtained the world's first 315KW permanent magnet direct drive drum explosion-proof certification, leading the belt drive system slimming revolution

(Summary description)On July 22, 2018, Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd. (JASUNG) was again recognized by the Chinese Academy of Coal Science, and obtained the world's first 315KW permanent magnet drum explosion-proof certification!
As the current domestic explosion-proof three-phase permanent magnet synchronous electric drum with the largest power (315kW) for mines, it is an emerging product in coal mine electromechanical equipment. Among the national inspection agencies, the Shanghai Coal Science Testing Center is based on relevant institutions and safety standards. The center authorizes the qualification of electric drum inspection and inspection to inspect such products.
The above is made by Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd., the world's largest power (315kw) electric drum detection test chart, the system efficiency is 97%! Before this technology, the world's largest electric drum was 75kw.

Information

On July 22, 2018, Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd. (JASUNG) was again recognized by the Chinese Academy of Coal Science, and obtained the world's first 315KW permanent magnet drum explosion-proof certification! As the current domestic explosion-proof three-phase permanent magnet synchronous electric drum with the largest power (315kW) for mines, it is an emerging product in coal mine electromechanical equipment. Among the national inspection agencies, the Shanghai Coal Science Testing Center is based on relevant institutions and safety standards. The center authorizes the qualification of electric drum inspection and inspection to inspect such products. The above is made by Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd., the world's largest power (315kw) electric drum detection test chart, the system efficiency is 97%! Before this technology, the world's largest electric drum was 75kw.

As the current domestic explosion-proof three-phase permanent magnet synchronous electric drum with the largest power (315kW) for mines, it is an emerging product in coal mine electromechanical equipment. Among the national inspection agencies, the Shanghai Coal Science Testing Center is based on relevant institutions and safety standards. The center authorizes the qualification of electric drum inspection and inspection to inspect such products. Due to the low-speed and high-torque characteristics of the tested electric drum products, the transmission power far exceeds the power of traditional electric drums, making it difficult for the original inspection capabilities to meet the test requirements. For this reason, the Shanghai Coal Science Testing Center is anxious for customers and organized The special technical meeting used the existing equipment to quickly formulate a simple modification plan on the basis of the original electric drum test bench. The Mining Machinery Safety Inspection Institute and the Electrical Explosion-Proof Safety Inspection Institute worked closely together to design drawings, process and make, install and debug. It only took more than one month to successfully complete the inspection task, which was recognized by users.

For a long time, the traditional electric drum in the mine adopts the structure of built-in oil-cooled motor, reduction gear and oil-immersed cooling and lubrication in the drum. The motor works in a narrow and relatively sealed space, and the gear transmission is in harsh working conditions and has relatively poor heat dissipation conditions. Factors such as poor make it difficult to increase the power of the product. With the development of the industry, the permanent magnet synchronous drum motor is not only the rotor of the permanent magnet motor, but also assumes the function of the original transmission drum transmission belt. It uses the characteristics of the low speed and large torque of the permanent magnet motor, without the need to set a reduction gear, plus the permanent magnet motor. High-efficiency transmission characteristics, and an external cooling system can be installed, so its transmission power is greatly improved.

As a well-known third-party inspection agency in China, the Shanghai Coal Science Testing Center is committed to the testing and inspection of mining products to ensure the safety of coal mining. The issuance of the explosion-proof certificate for the 315kW explosion-proof three-phase permanent magnet synchronous electric drum for mines has opened the prelude to the application of high-power permanent magnet synchronous electric drums in coal mines. Faced with the continuous emergence of new products of coal mining equipment, Shanghai The Coal Science Testing Center will continue to improve its own inspection capabilities, develop more advanced inspection equipment, and continue to escort the safe use of coal mine electromechanical products in the mine.
