Five years of sharpening the sword to rewrite the monopoly pattern of foreign brands
"After five years of development and testing, we have successfully developed an oil-free water lubricated single screw air compressor, which broke the long-term monopoly of foreign brands in one fell swoop and became another benchmark for "Creation in Shunde"." Dai Jiaman, director of the operation and management department of Guangdong Zhengli Precision Machinery Co., Ltd., who came back from the China International Fluid Machinery Exhibition, revealed to reporters the latest scientific research results of the project. At present, the project has applied for a patent.
Long-term monopoly of foreign brands
In the field of air compressors, in the past, whenever water-lubricated single screw compressors were mentioned, everyone would naturally think of a famous Japanese brand. This company has been on the market since the 1980s and has a monopoly in the market. The person in charge of Zhengli Precision R&D Center told reporters that the company has gradually improved and improved the technology of water-lubricated single screw compressors, and by the mid-1990s, it was close to perfection. Both waterproof materials and various aspects of performance were quite perfect. By the late 1990s, the performance of the product became more stable. The person in charge of the R&D center pointed out that the Japanese company has always mastered the core technology of oil-free single screw lubrication. In its cooperation with a Taiwanese company for large-scale production in the mainland, it is limited to the transfer of technology for the whole machine part. The technical part still needs to purchase from its extremes, has absolute right to speak in the industry, and has been in a monopoly position for many years.
Inspired by repairing foreign brands
It is precisely because of the long-term monopoly of foreign brands that many companies in the Pearl River Delta have encountered difficulties when using foreign brands: the warranty service period provided by the product is about two years, which has caused many users in the Pearl River Delta to encounter problems and cannot get them in time. solve. "The far water cannot save the near fire", many customers have sent out distress signals to Zhengli Seiko, which is also a single screw air compressor field. Zhengli Precision already has a fairly good technical foundation in the field of single-screw air compressors. Basically, it has broken through all technical problems in the research and development of water lubrication products, and has determined three sets of technical solutions. It can be said that by repairing the products of foreign brands, the company has actually well reviewed the three sets of technical solutions that the company has put forward. After diagnosis, it is determined that the research direction of one of the solutions does not have the technical problems exposed by foreign brands. This greatly encouraged the company's R&D personnel, excited the researchers of Zhengli Precision, and confirmed the feasibility and advancement of the third set of technical solutions.
The person in charge of the technology pointed out that Zhengli Precision's research on water-lubricated single screw compressors, among which the research results proposed for the product in the optimal solution, were already in the leading position in the industry at that time. In 2008, Zhengli Precision accelerated its efforts on the basis of the original scientific research, and added more than 1 million yuan in scientific research funding to further improve the plan and achieve new breakthroughs.
Five years of research and development broke the monopoly in one fell swoop
After 5 years of development and testing, Zhengli Seiko finally succeeded in manufacturing a high-tech product at the beginning of this year—oil-free and water-lubricated single screw compressor, breaking the foreign monopoly in this product. The person in charge of the R&D center told reporters that the entire set of equipment is made in China except for the bearings and star wheel materials supplied abroad.
Whether the oil-free water-lubricated single screw compressor can achieve sufficient displacement under the rated power is recognized in the industry to test whether the meshing pair has high precision. The longevity and energy-saving patent of Zhengli Precision's high-precision meshing pair breaks through the shortcomings of low viscosity and low sealing of water, and the volumetric efficiency still maintains a very high level. For example, Zhengli Seiko OGWFD22 has an exhaust pressure of 0.7MPa, an exhaust volume of 3.5m3/min, and a motor power of only 21.88kW, which is superior to similar famous foreign brands. So far, several units have been tested in customers and are in good condition.
Environmental protection and energy saving technology is at the international advanced level
Zhengli Precision Oil-free water-lubricated single-screw compressor not only inherits the characteristics of oil-injected single-screw energy saving, long life, and quietness, but also has the following characteristics: such as providing oil-free high-quality compressed air, low operating and maintenance costs, and energy saving , Low specific power, more efficient and energy-saving than oil-free twin-screw compressors. This is the biggest advantage of positive air compressors; in terms of environmental protection, the product uses pure water that meets drinking water standards instead of lubricating oil and rotors. The bearings are lubricated with grease, the star wheel is a self-lubricating bearing, and uses a high-performance water filter to filter impurities, which fully meets the requirements of environmental protection. At the same time, it also has the characteristics of low noise. The selling price of this series of products is 10% to 15% lower than that of foreign products of the same specification.
Dai Jiaman pointed out that the advent of oil-free water lubricated single screw compressors, in addition to breaking the long-term monopoly of foreign brands, more importantly, more extensive applications, suitable for medicine, food processing, beer brewing, advanced spraying, chemical fiber, high Piezoelectric insulation, powder storage and drying, film, film manufacturing, electronics, printing industry, precision control instrumentation, aerospace industry and other industries that require oil-free high-quality air, environmental protection and energy saving technology are at the international advanced level. When participating in the exhibition in Beijing, a leading machinery company in Beijing conducted a careful comparison of the products of its peers and fully affirmed the products and technology of Zhengli Precision.
Energy-saving and environmental protection has become a corporate consensus
"After our products came out, the company's customers took the initiative to come to the door after learning the project information, and even many of them were customers in new fields." The person in charge of Zhengli Precision R&D Center pointed out that this phenomenon makes the company's scientific researchers very excited, reflecting Domestic companies have a sense of innovation and energy conservation and environmental protection. At present, energy-saving and environmentally friendly products are not only popular in Europe and the United States, but have also become the consensus of domestic companies, representing the future trend. At the mechanical parts exhibition held in Shunde on November 3 this year, Zhengli Precision's water-lubricated single screw provided the exhibitors with compressed air. The silent effect and the technical highlights of water lubrication demonstrated by the on-site startup won the site visit Great attention from customers.
“Whether it is at the Beijing exhibition or the Shunde exhibition, the oil-free water-lubricated single screw compressor with independent intellectual property rights of Zhengli Precision is particularly favored by customers." Dai Jiaman said that Zhengli Precision will continue to increase investment in technology research and development in the future , Expand technical cooperation with famous domestic scientific research institutions, further improve and improve the company’s products and technologies, and strive to participate in the formulation of relevant national standards for the product as a representative of the enterprise, and better polish the "Shunde Creation" brand. Continuously interpret the business philosophy of "creating value for customers" to the society.
