During assembly, an oil ring without annular leakage is formed. The oil ring is worn during operation, and there is no leakage after the oil ring opening is wide. The oil consumption rate reaches the international leading level of 0.04g/ kW.h. After the product is promoted in China, it can save 200 billion yuan of environmental protection investment for the country every year. At the same time, it can save oil and reduce the maintenance cost of more than 30 billion yuan. At present, the piston ring because of the thin chromium layer (about 12 lines), the life is shorter. The product chromium layer reached about 20 silk, but easy to collapse chromium. Can you help solve it? The company pays attention to technological innovation and product research and development, research and development of the production of multifunctional heterofiber casting steel dimensional cleaning machine, seed cotton sales drying equipment, wind power transmission equipment enjoys a good reputation in the market. In particular, the production technology of the multifunctional heterosexual fiber cleaning machine is in the leading level in China and has obtained the national utility model patent.
