Application case of bellows type expansion in Xiamen Metro Line 2 project

The official website of Shanghai Songjiang shock absorber Group Co., Ltd. introduces to you: bellows type expansion in Xiamen Metro Line 2 project information. Songjiang group provides flexible rubber pipe joint products for HVAC systems of several metro lines in Xiamen. The following is the introduction of the bellows type expansion contract for line 2.

Introduction to Xiamen Metro Line 2 project

Xiamen Metro Line 2 has a total length of 41.6km and 32 stations, with an average station spacing of 1.32km, all of which are underground lines. Starting from Wuyuan Bay in the East and reaching Tianzhu Mountain in the west, it mainly passes through Wuyuan Bay, Guanyinshan area, Jiangtou area, Yuandang Hubei area, Haicang new city and maluanwan area, serving as the East-West skeleton line from Xiamen island to Haicang, and building a rapid cross sea connection between Xiamen Island and Haicang District.

The vehicles of Xiamen Metro Line 2 are the first batch of permanent magnet motor traction systems in domestic metro projects. The permanent magnet motor adopts a fully sealed structure, with low maintenance cost, energy saving, environmental protection and high power. The energy-saving index is expected to reach more than 25%.

Bellows type expansion mainly uses the unique properties of rubber, such as high elasticity, high air tightness, medium resistance and radiation resistance. It is made of polyester cord fabric with high strength and strong cold and heat stability. It is cross-linked by high-pressure and high-temperature molding. It has high internal density, can withstand high pressure, excellent elastic deformation effect, product structure design, high end face arc, long curve and large multiple displacement functions, It is especially used in places with complex geological conditions, large settlement range and frequent changes in cold and heat during pipeline movement, which are easy to cause pipeline damage.
