The countdown to the Beijing Winter Olympics has entered the countdown, and China's intelligent manufacturing on the ice and snow field is showing its talents. Among them, the "made in Shandong" snow wax car is an extremely shining star. This big man is China's first snow wax car with complete intellectual property rights. Its design team leader is Shandong Industrial Design and Research Institute located in Yantai High-tech Zone. It is carried by Yantai Manufacturing and Yantai Dondel Industry Co., Ltd. Hydrogen circulation pump, "clock" manufactured by Yantai Long-lasting Watch Group.

The hydrogen fuel tractor equipped with Snow Wax uses WEF160 hydrogen fuel cell, which is the first 162kW fuel cell heavy truck in China. The tractor is equipped with a hydrogen circulation pump produced by Yantai Dondel Industry Co., Ltd.

The hydrogen circulation pump is a key component of a hydrogen fuel cell engine, and plays an important role in improving fuel utilization and ensuring hydrogen safety (hydrogen overflow causes unsafe factors in the external environment). For the hydrogen circulating pump, it is necessary to have a good sealing design (hydrogen is easy to leak), strong water resistance (the remaining hydrogen after the stack reaction has a small amount of water vapor), a large flow (suitable for high-power stacks), and pressure output. Stability (low pressure to high pressure), oil-free (guarantee hydrogen purity), etc., the technical difficulty is much higher than that of traditional gas circulation pumps.

The reporter learned from Yantai Dondel Industry Co., Ltd. that the hydrogen circulating pump has completed 82 corresponding DV tests and 4 durability tests, including normal temperature and normal pressure durability test, salt spray durability test, high and low temperature durability test, hydrogen durability test, etc. Among them, the hydrogen durability test has been completed for 18,000 hours, and it is the only manufacturer at home and abroad that has actually used hydrogen to run for more than 18,000 hours on the test bench. In addition, in 2021, it passed the first set of EMC tests in China.

As of the end of December 2021, a sample of 40 fuel cell vehicles on the market has been tracked and confirmed, with a cumulative mileage of 7,686,374 kilometers, making it the BOP component manufacturer with the longest application time for hydrogen fuel cell vehicles in China.
