Reliability is the biggest gap between domestic mining equipment and imports

Reliability is the biggest gap between domestic mining equipment and imported mining equipment, and it is also the fundamental factor affecting China's mining equipment occupation of high-end market and exports. The key to improving the competitiveness of domestic mining equipment products is to improve the reliability of domestic mining equipment as soon as possible and shorten the gap with foreign products.

Through the analysis and research on the quality title topics frequently appearing in domestic mining equipment products, this title topic can be solved from the following ways: First, through the improvement of design means and tools, improve the reliability from the source of design. High pressure mill. The focus of this work should be to promote and use 3D CAD and computer-aided test CAT technology to achieve simulation assembly, dimensional interference analysis, simulated stress analysis, strength check, fatigue analysis and machine simulation calculation analysis. The second is to make full use of some advanced advanced technologies that have matured abroad, such as electromechanical and hydraulic integration technology, advanced electronic control technology and load sensing technology to realize intelligent control of sand washing machine for mining equipment. The third is to improve the quality of domestic components and basic components, such as the quality of engines, hydraulic torque converters, power shift transmissions, pumps, valves, motors, hydraulic cylinders, seals, fasteners and electrical components. It is the key to improving the reliability of domestic mining equipment, or directly implementing international procurement. The fourth is to strengthen the management of process links, especially the management of assembly and commissioning. Before the machine leaves the factory, it will carry out strict test and machine testing according to national standards, and all the minor faults that occur in the early stage of mining equipment will be excluded from the factory. machine. The fifth is to strengthen the inspection of foreign associations and external parts to strictly control the quality of foreign and external parts.

Improve service level

With the development of the times, the purchasing psychology of users is also changing. From the past, simply considering the price shift to comprehensive consideration of the overall value of equipment, foreign brands with high cost performance are favored by more and more users, and the advantages of low prices of domestic mining equipment will be It has been replaced by the advantages of foreign mining equipment that pursues high reliability. Therefore, domestic mining equipment enterprises must strengthen the after-sales service, especially the training of sandblasting machines for weak links such as training, guidance and regular return visits. In recent years, the domestic strength in after-sales service has indeed been strengthened. For example, in order to make the corporate service concept more humanized, Sany Heavy Industry took the lead in integrating the corporate culture into the enterprise service field and introduced the CI design concept. It was the first in the same industry in the country to launch the service mascot logo-type stone breaking machine. On the basis of attaching great importance to after-sales service, Sany Heavy Industry quickly adjusted the investment of funds raised in 2003 according to the market conditions, and turned to the after-sales network construction project that was originally intended to expand the production capacity of mining equipment that is still immature in some markets. , achieved good results.

Accelerate the process of internationalization

Under the situation that the domestic market is not smooth, domestic mining equipment enterprises should fully understand and give play to their own advantages and actively expand exports. This is not only the current important task of mining equipment enterprises, but also the inevitable development direction of the vibrating screen. At the bauma exhibition in Munich, Germany in 2004, more than 30 mining equipment manufacturers in China signed up for the exhibition. The exhibiting products were mainly shoveling transport machinery, compaction and paving machinery, representing the highest level of domestic mining equipment. However, except for a few manufacturers' products that have passed CE certification, most of the products cannot enter Europe at all. In terms of exports, China's product disadvantages are very obvious. However, domestic mining equipment companies can take advantage of their strengths and avoid weaknesses. At present, the advantages of domestic mining equipment industry export are mainly reflected in the following aspects: First, product coverage is wide, product adaptability is strong; second, low price and strong competitiveness; third, high export enthusiasm; fourth, the country From the aspects of taxation, export credit, special funds, and self-operated foreign trade rights, it provides favorable conditions for the export of enterprises. Domestic mining equipment enterprises should fully study these favorable conditions and promote the rapid development of export trade.
