JDZ Type Universal Bellows Compensator

JDZ Universal Bellows Compensator is a component used to compensate for the elongation or contraction of pipelines due to temperature changes. It is primarily applied in thermal pipelines, with common forms including waveform compensators and bellows. It is also known as a shock-absorbing bellows compensator, expansion joint, or伸缩节. It consists of a bellows (an elastic element) and accessories such as end pipes, brackets, flanges, and conduits.

Working Principle and Function

The JDZ Universal Bellows Compensator utilizes the effective伸缩 deformation of the bellows to absorb dimensional changes in pipelines, conduits, or containers caused by thermal expansion and contraction. It simultaneously compensates for axial, lateral, and angular displacement. Additionally, it can absorb equipment vibrations, reduce the impact of vibrations on pipelines, and absorb pipeline deformations caused by earthquakes and ground settlement.

Technical Parameters and Application Scenarios

The technical parameters of the JDZ Universal Bellows Compensator include:

• Working Pressure: 0.6MPa, 1.0MPa, 2.5MPa
• Nominal Diameter: DN15 to DN3000
• Displacement Direction: Axial (with minor lateral and angular displacement)
  These parameters make the compensator suitable for various industrial pipeline systems, especially in scenarios requiring absorption of multiple types of displacement.

Installation and Usage Requirements

When installing the JDZ Universal Bellows Compensator, the following points should be noted:

1. Ambient Temperature: Should be within the range of -25°C to 60°C, with relative humidity ≤95%. Waterproofing and cooling measures should be taken in露天 or high-temperature environments.
2. Installation Method: Generally, it should be installed vertically. In special cases, it can be installed倾斜, but additional support components are required for protection.
3. Pipeline Height: When the pipeline height exceeds 2m, a platform should be set up to facilitate operation and maintenance.
4. Cleaning: The pipeline should be cleaned before installation to remove污物 and weld slag. Valves should be cleaned again after installation.
5. Bypass Pipeline: To ensure the production process can continue during faults or maintenance, a bypass pipeline should be added.

Through the above introduction, one can better understand the definition, working principle, technical parameters, as well as installation and usage requirements of the JDZ Universal Bellows Compensator.
