In recent years, the technical level of my country’s textile machinery equipment has improved by leaps and bounds. Not only the complete sets of cotton spinning equipment with good foundation have been significantly improved in intelligence, but even the relatively weak printing, dyeing and non-woven equipment have also made great progress. . However, while feeling these achievements, the reliability of domestic textile machinery equipment is still a lingering embarrassing issue. According to a survey, up to 81.5% of user companies believe that the stability of domestic textile machinery is poor. It can be seen that there is still a certain gap between the reliability of domestic equipment and user needs. So how can this gap be shortened?
Reliability gap
According to textile enterprises, foreign equipment has been installed and debugged after arriving at the enterprise. , it can start running smoothly after a week; while domestic equipment often takes a month to start running, and someone has to track it within three months, and minor problems often occur and have to be stopped for maintenance, which not only reduces efficiency, It also increases the company’s maintenance costs.
Compared with imported textile machinery, there is still a large gap in the overall level of domestic textile machinery equipment. This is mainly reflected in the following: First, the early failure rate of the main engine is high and the reliability index gap is Large, the whole life cycle cost is relatively high; second, the product quality or accuracy consistency is poor, early failure, and the life index is lower than the level of international famous brand products; third, the equipment has a long running-in period and does not meet the user’s requirements for high quality, high efficiency, and low consumption. To improve the reliability of textile machinery, attention needs to be paid to all aspects of production, management, and manufacturing, and harmonious cooperation from many aspects is also required. At present, textile machinery companies have generally paid more attention to product reliability, and many companies have made efforts to improve product reliability.
Similar ideas
Many domestic companies hold similar ideas and even feel that there is no need to do anything It’s so perfect that the machine won’t last a few years, and no matter how refined or well-made it is, it can’t escape the fate of being eliminated. With this kind of thinking, it is naturally difficult to produce good products. Domestic enterprises often believe that the reliability and quality of products are checked by inspectors. However, well-known foreign textile machinery enterprises do not have specialized inspection institutions and inspectors for their own parts and assemblies, except for inspection of external parts. , every process and every position must conduct self-inspection. This is a very big gap between us and advanced foreign companies.
The concepts of enterprise decision-makers play an important role in improving product reliability. Many operators have unclear understanding of reliability or have misunderstandings, which makes enterprises lack effective reliability. management and mechanisms. The higher a company attaches importance to reliability, the greater the substantial improvement in product reliability.
System integration
Reliability runs through design, manufacturing, assembly and after-sales service A system project should even be integrated with national standards and industry standards. It is precisely because enterprises have insufficient understanding of reliability that while domestic textile machinery products have improved in terms of design level and processing capabilities, their reliability has not been able to keep up.
Enterprises that want to improve product reliability should pay attention to the following points. First, before designing, the company’s R&D department must conduct comparative tests on the technical indicators of existing products and imported products to find out the advanced points. Second, strengthen information collection and management, accumulate historical data, conduct comprehensive analysis and comparison of information, identify weak links, identify key targets to overcome, and put forward corresponding improvement suggestions. Third, strengthen the construction of testing institutions, pay attention to personnel training, and formulate reliability testing standards.
Industry-university-research cooperation
The improvement of textile machinery reliability is the integration of multiple disciplines. After all, the power of individual enterprises to integrate scientific research results, knowledge, technology, capabilities, experience, etc. is weak, and it is an inevitable choice to take the road of industry-university-research cooperation to accelerate innovation and development. For some major, common technologies and forward-looking technologies and key equipment, with the support of the state, relevant enterprises can jointly raise funds, which is not only cheaper than repeated introduction, but also has independent intellectual property rights, which is conducive to improving core competitiveness and forming private brand products.
Chongqing Jinmao Textile Equipment Co., Ltd., Changzhou Hangyue Textile Machinery Parts Co., Ltd., Shanghai Far East Steel Wire Card Clothing Co., Ltd., Wuxi Owl Textile Equipment Co., Ltd., Qingdao Fengyi Textile Equipment Co., Ltd. and other five traveler manufacturers established the “New Generation Textile Equipment Traveler Technology Innovation Alliance” in 2011, and cooperated with the National Key Laboratory of Tribology at Tsinghua University to develop the “Traveler Surface Treatment Technology Research” project. At present, this project has successfully solved major key technical problems in surface treatment of travellers. The service life of travellers treated with this technology has reached more than 15 days (the service life of imported high-quality travellers is 15 days to 20 days), and the quality has reached the international advanced level.
Introducing advanced technology
Enterprises can also introduce advanced technology through joint ventures, cooperation, technology transfer, hiring foreign experts, etc. technology to improve product quality levels. For example, Guangshan White Shark Card Clothing Co., Ltd., located in Henan Province, has established a joint venture with Spanish Flexfort Guangshan Bruja Card Clothing Co., Ltd., which has introduced Spanish elastic card clothing manufacturing technology and equipment, significantly improving its wool spinning and brushed card clothing. The technical level and quality of elastic card clothing products. </p
