compared with single sphere rubber bellows , double sphere rubber joint’s advantages are its displacement is larger,instantaneous pressure on the larger deformation and so on, especially when installed in the export part of the pump. When the pump starts, instantaneous pressure is much higher than working pressure; double sphere rubber joint will reflect its advantages. Larger displacement and lower rubber aging speed of double sphere rubber joint will make better effects. However, its draft is very complex, requires high technical, so the cost is very high, thus the application number is smaller than single sphere rubber joint.
features of rubber bellows
1.rubber bellows can greatly reduce pipeline system shock and noise, and can fundamentally resolve pipe joints displacement, axial stretch and non-concentricity.
2. By using different materials, it can be made many kinds to cater
for different medium and environment. Such as acid resistance, alkali resistance, corrosion resistance, oil resistance and heat resistance etc.
3. The material is pure rubber, sealing is very good. It is in light weight, very easy
for installation . Rubber bellows has long life performance, but must be not contact
with sharp metal instruments to avoid piercing the sphere.
4. Rubber bellows can be used for lift and transportation of raw water and sewage, transportation of water supply cooling cycle water thermal power ,condensate water of metallurgy industry and chemical industry.
