In recent years, the technical level of China's textile machinery equipment has been improved by leaps and bounds. Not only has the intelligence of cotton spinning equipment with a better foundation improved significantly, but even relatively weak printing and dyeing and non-woven equipment have also made great progress. However, while feeling these achievements, the reliability of domestic textile machinery equipment is still an embarrassing issue. According to the survey, up to 81.5% of user enterprises believe that the stability of domestic textile machinery is poor, which shows that there is still a certain gap between the reliability of domestic equipment and the needs of users. So how can we close this gap?
According to the textile enterprises, foreign equipment arrives at the enterprise. After installation and commissioning, it can run smoothly after one week; while domestic equipment often runs after one month, and someone has to track it within three months. If something goes wrong, you have to stop for maintenance, which not only reduces the efficiency, but also increases the maintenance cost of the enterprise.
Compared with imported textile machinery, there is still a large gap in the overall level of domestic textile machinery equipment, which is mainly manifested in the following: first, the main engine has a high early failure rate, the reliability index gap is large, and the life-cycle cost is relatively high; Or the accuracy consistency is poor, the early failure, the life index is lower than the level of international famous brand products; the third is that the equipment has a long running-in period, which does not meet the user's requirements for high quality, high efficiency, and low consumption. To improve the reliability of textile machinery, we need to pay attention to all aspects of production, management, and manufacturing, and also need harmonious cooperation in many aspects. At present, textile machinery companies have generally paid more attention to product reliability, and many companies have made efforts to improve product reliability.
Many domestic companies hold similar ideas, and even feel that there is no need to make it too perfect. The machine will not be used for a few years, and it will be difficult to get rid of it even if it is as delicate as possible. With this thinking, it is naturally difficult to produce good products. Domestic companies often believe that the reliability of products and product quality are controlled by inspectors, and well-known foreign textile machinery companies have no special inspection agencies and inspectors for their parts and assemblies except for inspections of external parts. Every process and every post must be self-inspected. This is a very big gap between us and foreign advanced enterprises.
The concept of corporate decision-making plays an important role in improving product reliability. Many operators have unclear understanding or misunderstanding of reliability, which makes enterprises lack effective reliability management and mechanisms. The higher the degree to which companies value reliability, the greater the substantial increase in product reliability.
Reliability is a systematic project that runs from design, manufacturing, assembly to after-sales service, and should even be combined with national standards and industry standards. It is precisely because the company's understanding of reliability is inadequate that, while domestic textile machinery products have improved in terms of design level and processing capacity, the reliability cannot 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 should conduct a comparative test on the technical indicators of existing products and imported products to find advanced points. Second, strengthen information collection and management, accumulate historical data, and make comprehensive analysis and comparison of information, find weak links from it, find out key targets to overcome, and propose corresponding improvements. Third, strengthen the construction of testing institutions, attach importance to personnel training, and formulate reliability inspection standards.
The improvement of the reliability of the textile machinery is a blend of multi-disciplines. After all, the strength of an individual enterprise to integrate scientific research results, knowledge, technology, capabilities, experience, etc. is weak, and it is an inevitable choice to accelerate innovation and development by taking the road of industry-university-research cooperation. Some major and common technologies, forward-looking technologies and key equipment, with the support of the state, related enterprises jointly raise funds, which not only lowers the cost of repeated introductions, but also has independent intellectual property rights, which is conducive to improving core competitiveness and forming private label products.
Five wire traveller manufacturers including Chongqing Golden Cat Textile Equipment Co., Ltd., Changzhou Hangyue Textile Machinery Co., Ltd., Shanghai Far East Wire Clothing Co., Ltd., Wuxi Owl Textile Equipment Co., Ltd., Qingdao Fengyi Textile Equipment Co., Ltd., etc. The "New Generation Textile Equipment Traveler Technology Innovation Alliance" was established, and the "Research on Traveler Surface Treatment Technology" project was developed in cooperation with the National Key Laboratory of Tribology of Tsinghua University. At present, the project has successfully solved the major key technical problems in the surface treatment of travellers. The life of travellers treated with this technology has reached more than 15 days (the lifespan of imported premium travellers is 15-20 days), and the quality has reached the international advanced level.
Introduce advanced technology
Enterprises can also introduce advanced technologies through joint ventures, cooperation, technology transfer, and hire foreign experts to improve product quality. For example, Guangshan White Shark Card Clothing Co., Ltd., located in Henan Province, has established a joint venture with Spain's Flickers Card, Guangshan Bruha Card Clothing Co., Ltd., which has introduced Spanish elastic card clothing manufacturing technology and equipment, which has significantly improved its wool spinning and brushing. Technical level and quality of elastic card clothing products.
