The selection and number of rotations of the rotary compensator are mainly based on the following considerations:
In terms of selection:
The pressure and temperature of the steam in the pipe: The selection of the rotary compensator should be based on the pressure and temperature of the steam within the pipe. Different compensators are suitable for different pressure and temperature ranges. For example, some compensators may be suitable for low-pressure pipelines, while others may be suitable for high-pressure pipelines.
The actual direction of the pipeline: The arrangement of the rotary compensator should be carried out in conjunction with the actual direction of the pipeline to ensure its effectiveness and efficiency.
Reduce eccentric moment: In order to control the generation of running eccentric moment, the height of the rotary compensator body should be reduced as much as possible. For example, when the nominal diameter is in a specific range, the height of the compensator may take some minimum value.
Increase the ability to compensate: When installing the rotary compensator, pre-bias installation should be carried out according to the thermal displacement of the pipe section between the two fixed brackets, so as to increase the compensation ability of the compensator and reduce the lateral displacement of the pipeline.
Bracket setup : Due to the large compensation capacity of the rotary compensator, the pipe section of the compensator will produce a certain lateral displacement during operation. Therefore, sliding brackets, rolling brackets or guide brackets should be provided to reduce the thrust on the fixed bracket.
In terms of number of rotations:
The number of rotations of the rotary compensator can be calculated by a specific formula, the specific formula is: number of rotations N = θ/ (360°/N), where θ represents the measured angular error and N represents the transmission ratio of the rotary compensator.
Please note that the selection of the rotary compensator and the determination of the number of rotations is a complex process, involving many factors and technical details. Therefore, in practical applications, you can consult us by telephone at any time to ensure the accuracy and validity of model selection and calculation. At the same time, when installing and using the rotary compensator, the relevant safety regulations and operation guidelines should be strictly followed to ensure the normal operation of the equipment and the safety of personnel.
