How to install concentric reducing rubber soft coupling?
Reducing concentric rubber soft joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. This product takes advantage of rubber's elasticity, high airtightness, medium resistance, weather resistance and radiation resistance, and uses polyester cord fabric with high strength and hot and cold stability. After cross-mixing, high pressure and high temperature mold vulcanization.
 
After the concentric rubber joints of different diameters enter normal operation, check whether the displacement of the spring bracket under the working load is in accordance with the design. After the equipment stops running, check whether the indicator plate returns to the load installation position. By testing the above precautions, the correct installation data can be obtained to ensure stable vibration damping and vibration resistance and safety. The rubber shock absorber achieves a high degree of vibration damping under both axial and lateral pressure, especially for generators, engines and systems, with an application range of approximately 25 Hz (1.500 rpm). Need to change the thickness of the tube, will also be used where the flow rate changes, so that different sizes of tubes are connected in a straight line to achieve different caliber fittings. Concentric rubber joints of different diameters (large and small heads) are characterized by high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration damping, good noise reduction, easy installation, etc. The maximum bearing pressure of rubber joints of different diameters is 1.6MPa. Like common rubber joints, they are also composed of inner rubber layer, nylon cord reinforced layer and outer rubber layer.
 
Thin-walled tubes with outer diameter up to 5mm and wall thickness less than 2.25mm are made of medium carbon steel and used for manufacturing mechanical parts, such as stressed parts of buses and conveyors. Concentric reducer rubber soft joints are produced under cold-rolled or heat-treated conditions, and hot-rolled cast tubes are produced under cold-rolled or heat-treated conditions. The outer diameter of the reducer cold-rolled concentric rubber soft joint is generally larger than 32mm and 2.5 to 75mm.
 
The brittleness and toughness of concentric reducer rubber flexible joints seem to be opposite, but different from hard pipes and hoses. It can be considered that the lower the hardness, the softer it is. Hammered cracked metal is brittle, but uncracked metal is not necessarily ductile. This is because some metals are hard and do not crack, while others are soft and easily deformed. Ductility is the property of being affected by external forces and not easily damaged. Toughness is different from ductility. Soft data is not necessarily elastic.
