The compensation principle of maintenance-free rotating compensator is to form a couple of equal-sized and opposite forces by forming double rotating drums and L-arm. The force arm rotates around the Z-axis center to absorb the thermal expansion generated by the thermal pipes on both sides of the couple.

When the thermal expansion is absorbed, the maximum swing y value occurs when the couple arm rotates to 0, so the distance of the first guide bracket of the compensator should be increased.

Although the absorption thermal expansion increases with the increase of rotation angle 0 or couple arm L, in order to limit y swing too large, the value of 0 does not exceed the recommended value of the parameter table, and the value of L should be as large as possible, generally in the range of 2-6.

  • High Voltage Maintenance-free Rotary Compensator
  • High Voltage Maintenance-free Rotary Compensator
  • High Voltage Maintenance-free Rotary Compensator
Characteristics

1. The compensation capacity of a group of rotary compensators can reach 1800 mm.


2. There is no internal pressure thrust generated by the control pressure, so the fixed bracket of the two segments of the compensator can be made smaller.


3. The double sealing structure is adopted, the sealing filler is superior, the long-term operation does not need maintenance, and the working performance is reliable.


4. High compressive strength, good safety performance, maximum pressure up to 10 MPa, maximum temperature 540 C;


5. Easy installation, low heat loss, high cost performance;


6. The compensator has two basic combinations and dozens of variations.
