Technical Application and Prospect Analysis of Domestic Seals

At present, China's construction machinery industry has introduced a large number of host design and manufacturing technologies from developed countries, and gradually adopted the international advanced sealing system design concept and sealing device application technology. However, due to the constraints of the domestic seal industry manufacturing level, the application level of construction machinery seal technology is still lagging behind the international advanced level of about 20-25 years, and the normal working hours of the host without leakage are only about 400h, which is less than 1/10 of the international advanced level.
