Product characteristics

This product uses the effective expansion and deformation of its working body bellows to absorb the size change of pipeline, conduit, container, etc. caused by thermal expansion and contraction, or to compensate for axial, lateral and angular displacements of pipeline, conduit, container, etc. The JDZ-type axial inward pressure corrugated compensator utilizes its own main elastic element, the expansion and contraction of bellows and offset to carry out the compensation of pipeline displacements, with a large compensation capacity and good elasticity, the product is suitable for conveying seawater, freshwater, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, oil products, air, gas and other media. It has a large compensation capacity and good elasticity, and is suitable for the transportation of seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas and other media.

Calculation of JDZ type internal pressure corrugated compensator on the support force:

Internal pressure thrust: F=100-P-A Axial elasticity: Fx=Kx-(f-X)

Transverse elasticity: Fy=Ky-Y Bending torque: My=Fy-L

Bending torque: Mθ=Kθ-θ Synthesis of the bending torque: M=My+Mθ

Where: Kx: axial stiffness N/mm X: axial displacement mm

Ky: lateral stiffness N/mm Y: lateral displacement mm Ky: transverse rigidity N/mm mm Y: actual displacement in transverse direction mm

Kθ: angular stiffness N-m/degree θ: actual displacement in angular direction

P: working pressure MPa A: effective area of bellows cm2 (check sample)

L: distance from the center point of compensator to the support m

JDZ type axial internal pressure type corrugated compensator application example:

a carbon steel pipeline, nominal diameter 500mm, working pressure 0.6MPa, medium temperature 300 ° C, the environment is very low temperature -10 ° C, the compensator installation temperature of 20 ° C, according to the layout of the pipeline (as shown in the figure), the need to install a pressure type corrugated compensator to compensate for the axial displacement of X = 32mm, the transverse displacement Y = 2.8mm, angular displacement θ = 2.8mm, and the displacement of θ = 2.8mm, and the displacement of θ = 2.8mm. The angular displacement θ = 1.8 degrees, known L = 4m, the number of compensator fatigue damage according to 15,000 times to consider, try to calculate the force of the bearing A.
