上海淞江减震器集团有限公司介绍：供水管道25公斤DN300橡胶膨胀节产品信息，这里说下DN300橡胶膨胀节参数：长度245mm，轴向压缩25mm，轴向拉伸14mm，横向位移15mm。.淞江集团为众多高层供水泵系统介绍高压橡胶膨胀节产品，起到减震和降噪的作用，以下是详细介绍。

 

淞江集团生产的2.5Mpa橡胶膨胀节采用了锻打法兰进行了冷镀锌处理，然后与橡胶管组合，并且加装了限位装置，起到了防止拉脱的作用，DN300单球镀锌法兰橡胶接头在使用的过程中起到了减震和降噪的作用，从而保护水泵设备的长期使用寿命，是众多泵房的降噪选择。

限位装置说明：淞江集团所生产的限位橡胶接头产品都配有高强度限位装置，所有螺杆采用8.8级高强度，并非4.8级可比的，耳板也是加宽、加大、加厚，没有对比就没有伤害，而且，我们还配有专用的缓冲胶块，起到了缓冲和降噪的作用。

 

Shanghai Songjiang shock absorber Group Co., Ltd. introduces the information of 25kg DN300 rubber expansion joint of water supply pipeline. Here are the parameters of DN300 rubber expansion joint: length 245mm, axial compression 25mm, axial tension 14mm, transverse displacement 15mm. Songjiang group introduces high-pressure rubber expansion joint products for many high-rise water supply pump systems, which play the role of shock absorption and noise reduction. The following is a detailed introduction.

 

The 2.5MPa rubber expansion joint produced by Songjiang group adopts forged flange for cold galvanizing treatment, and then combines with rubber pipe, and is equipped with limit device, which plays the role of preventing pulling off. DN300 single ball galvanized flange rubber joint plays the role of shock absorption and noise reduction in the process of use, so as to protect the long service life of pump equipment, which is the best choice for noise reduction of many pump stations Choose.

 

Limit device description: the limit rubber joint products produced by Songjiang group are equipped with high-strength limit device. All screws adopt 8.8 grade high strength, which is not comparable to 4.8 grade. The ear plate is also widened, enlarged and thickened, so there is no harm without comparison. Moreover, we are also equipped with special buffer rubber block, which plays the role of buffer and noise reduction.
