With the development of domestic brands, the market share of the domestic inverter enterprises are gradually expanding, especially accelerated instead of foreign brands of trend in recent years. It has yet to be and international top brands such as Siemens, ABB, comprehensive competition strength, but on the part of niche products and market shows a certain competitive advantage, market share gradually expanding.
The development of frequency converter in our country
First, foreign brand monopoly market, in the 1990 s import high voltage inverter is mainly supporting key projects in our country, the domestic customers not yet aware of energy saving effect, the product price is higher.
Second, domestic companies found high voltage frequency conversion market, to seek technological breakthroughs, but facing the customer trust and the product is not stable, although priced at less than half of the foreign brand, but due to performance issues, domestic enterprises can only in the small customer orders.
Third, the domestic enterprises make a breakthrough, first of all, through the accumulation, is not the technical difficulties, reliability has been to meet customer requirements, gradually establish a brand, foreign brands generally lags behind that of the local enterprises in the services, for domestic enterprises good development opportunity.
Fourth, the domestic enterprise full blossom, the large customer realized foreign brand monopoly market, no longer will be more attention to domestic enterprises, sped up localization process.
The traditional energy saving way - asynchronous servo energy-saving technologies
Asynchronous servo controller and frequency converter actually, is only relative to the general frequency converter, vector drive direct drive servo is to use an asynchronous induction motor, and which has the function of feedback device. Asynchronous servo integration with variable frequency and synchronous servo technology of energy conservation, and the advantages of them together, and overcome the shortcomings of their respective, disruptive revolutionary technology is injection molding machine industry. Its main advantages are as follows:
1, the system dynamic response is fast, cost-effective, injection molding machine can improve production efficiency.
2, power saving rate is high.
3, installation is simple.
Section 4, asynchronous servo electrical failure, does not affect the injection molding machine.
5, the late maintenance cost is low.
Asynchronous servo controller can be used in the injection molding machine, die-casting machine, shoes machine, aluminum extrusion machine, punch and other hydraulic press, air compressor and other energy-saving projects requires precise control of the motor. Although asynchronous servo is still on the stage of popularization, fame is not big enough. But from asynchronous servo injection molding machine has been completed, you can see that in the effect of the renovation project of asynchronous servo energy-saving technology relatively better energy saving technology, the upgrade product of frequency converter, synchronous servo will get a greater space for development and application of energy conservation.
Energy-saving reform - suzhou million source asynchronous servo injection molding machine and energy saving disruptive technology, completely different from the traditional energy saving mode, the asynchronous servo energy-saving cleverly combines the advantages of variable frequency energy saving technology and synchronous servo energy-saving technology, overcome the shortcomings of their respective again at the same time, high energy saving, low cost.
