  • Detail

The permanent magnet synchronous motor system for pumps has been put on record on the national group standard information platform recently, Zhejiang Wenling Pump Industry Association issued and implemented the group standard t/wlby01-2019 permanent magnet synchronous motor system for pumps. This standard was drafted under the leadership of Leo Group Zhejiang Pump Industry Co., Ltd. New Territories Pump Industry Group Co., Ltd., Zhejiang Dayuan Pump Industry Co., Ltd. and Zhejiang Dongyin Pump Industry Co., Ltd. recently, Zhejiang Wenling Pump Industry Association issued and implemented the group standard t/wlby 01-2019 pump permanent magnet synchronous motor system. The standard was drafted under the leadership of Leo Group Zhejiang Pump Co., Ltd. and jointly prepared by 14 enterprises including new territories Pump Group Co., Ltd., Zhejiang Dayuan Pump Co., Ltd. and Zhejiang Dongyin Pump Co., Ltd. At present, the standard has been filed on the national group standard information platform

in order to comply with the national energy-saving transformation and the development needs of China's industrial automation industry, some industries began to use permanent magnet synchronous motors as the main power output, but in the field of commercial and industrial water pumps, the application of permanent magnet synchronous motors is still in its infancy

the group standard of pump permanent magnet synchronous motor system specifies the composition, model and basic parameters, technical requirements, inspection rules, delivery preparation, etc. of the pump permanent magnet synchronous motor system. It is the first group standard in the field of pump permanent magnet motor in China. It fills the gap in the national and industrial standards of the pump permanent magnet synchronous motor system, and reflects the advanced technical level of the domestic water pump industry

this standard is applicable to the design, production and inspection of pump permanent magnet synchronous motor system with motor efficiency of IE5. Its motor efficiency meets the requirements of international top IE5 energy efficiency standards, and the efficiency of supporting controller reaches the leading level at home and abroad. The fluid duct design process can take into account the heat dissipation of motor and controller. The size design standard is more conducive to energy-saving transformation, and the technical optimization greatly reduces the electromagnetic noise, It also has constant pressure mode and manual speed regulation mode, which provides favorable conditions and technical support for the intelligent creation of pump products

compared with the current small-scale induction motors that small-scale water pumps, air compressors and vacuum pumps rely on, permanent magnet motors have better product performance. They have the advantages of small volume, light weight, intelligence, green energy saving, etc., which are more difficult to control and energy-efficient than asynchronous motors. The integrated technology of permanent magnet motor and pump is conducive to improving the innovation ability of enterprises, enhancing the competitiveness of products, conforming to the world development trend, and will become a new development trend of the pump and motor industry in the future

both fixtures and samples should be placed in a high temperature environment to complete the tensile test. The pump and motor industry is a pillar industry in Taizhou, driven by Asia and Eastern Europe, and is listed as one of the seven hundred billion industrial clusters in Taizhou. Based on its functions, Wenling municipal Market Supervision Bureau actively encourages enterprises and social organizations to participate in the formulation and revision of international, national and industrial standards, as well as "made in Zhejiang" group standards and other group standards, actively guides industry leading enterprises to create standardization pilot projects at all levels, continuously increases the effective supply of standards, constantly stimulates the vitality of market players, promotes the transformation and application of enterprise innovative technologies, and seizes the international voice, Give full play to the role of standardization in promoting the transformation and upgrading of pump and motor industries, realize the "double transformation" from traditional block economy to modern industrial clusters, and from low-end production to medium and high-end manufacturing, and help escort the economic development of Wenling

up to now, 45 pump and motor enterprises in the city have led or participated in the preparation and revision of 34 national standards, 44 industrial standards, 5 group standards of "made in Zhejiang", and 2 other group standards. The "energy saving standardization demonstration and creation of pump (motor) intelligent manufacturing base" of Leo Group Zhejiang Pump Industry Co., Ltd. has been listed in the national energy saving standardization demonstration and creation project

in the next step, Wenling municipal market supervision bureau will provide accurate docking and tracking guidance services to help better implement the group standard that the instrument CPU (generally 89C52) i/0 has no output cloth, and strive to transform to industry standards and national standards, so as to make greater contributions to the upgrading and development of the pump and motor industry
