Application 1

The actual working conditions of the high-pressure fuel pump in the cylinder are characterized by high working temperature, high working frequency and fast pressure change.

The requirements for seals are almost demanding, requiring high temperature resistance (engine temperature 100-160 ° C), opticur NC (Working life cycle reaches 1 billion), good follow-up (high operating frequency and fast pressure change). Due to the limitations of the sealing performance indicators, the market share of the global high-pressure fuel pump is currently occupied by Dr. Song and the Hitachi brand.

The VS011 seal developed by our company fully meets the working conditions of the high-pressure fuel pump. Through the accumulation of many customers in Guangzhou and Beijing and the accumulation of practical work experience, we have achieved satisfactory results. Many high-pressure fuel pumps currently on the market have been installed with our seals.
