Building too high-speed iron to promote the development of Jinyu
“I hope the relevant national ministries will speed up the preliminary work of the Taijiao High-speed Rail project and start the project as soon as possible, and strive to start construction in 2015 and give a tilt in the investment ratio.†On March 6th, Li Zhengyin, deputy to the National People's Congress and head of the Shanxi Provincial Department of Transportation In an interview, said. The cemented carbide seal-ring can be divided into both or the kinetic seal-ring and staticseal-ring, and constitutes mechanic seal together with the spring, rubber seal-ring and steel jacket.

Li Zhengyin said that at present, Taiyuan to Henan Jiaozuo to drive more than 8 hours. With a total length of 319.8 kilometers and a Taijiao high-speed railway passing through the revolutionary old district of Taihang Mountain, the drive from Taiyuan to Jiaozuo will be shortened to 1 hour and 20 minutes, greatly bringing closer the economic and social links between Shanxi and Henan.
“In addition, the approval of high-speed railways from Datong to Zhangjiakou has also entered the national level. We hope to start construction this year,†said Li Zhengyin.
This year, Li Zhengyin also pays special attention to issues concerning the inclusion of special vehicles for highway supervision and inspection into law enforcement duty vehicles. "After the bus reform, only the maritime transport agencies of the Shanxi Transportation and Transportation System can be equipped with law enforcement and duty vehicles, and highway agencies will supervise and inspect special vehicles. According to Article 73 of the Highway Law, Article 15 of the Road Traffic Safety Law and the Ministry of Transport The “Administrative Measures for Special Vehicles for Supervision and Inspection of Highways†stipulates that special vehicles for highway supervision and inspection shall belong to vehicles for law enforcement and enforcement.†Li Zhengyin recommends that special vehicles subject to supervision and inspection of roads be identified by law enforcement and duty vehicles.
In addition, Li Zhengyin also suggested that the "Road Transportation Regulations" and related supporting regulations be amended as soon as possible. With the rapid development of the road transport industry, many provisions of the regulations and related supporting regulations are no longer suitable for the current road transport development needs. If a small car with a small safety risk is required to apply for ordinary cargo transportation, it still needs to be approved. Practitioners must obtain a qualification certificate, which restricts the development of the ordinary trucking industry and the express delivery industry of small cars.
The precision seal-ring is made of high quality materials by an advanced process, having very complicated shapes, high accuracy, stable mechanic properties, much higher wear and corrosion resistance, and a service life of more than twenty thousand hours in the normal case.
The Seal Ring will be used mainly for waste water pump,water discharge pump for mines, centrifugal pump, centrifuge, slag slurry pump and slurry abrasion and corrosion. The seal-ring will be installed on the pump body andratatingaxle, and forms through the end face of the kinetic and static ring a liquid or gas seal.
