Centrifugal compressor installation process

The installation of a centrifugal compressor is a rigorous engineering task that must be carried out according to specific procedures to ensure the compressor’s performance and safety. Here are the key steps in the installation process: 1. **Preparation**: Check whether the installation site meets the technical requirements, including floor levelness and a clean environment, to ensure there is sufficient space for installation and maintenance tasks. 2. **Equipment verification and placement**: Before installation, a thorough inspection of the compressor equipment should be carried out, including verifying the model, specifications, and the integrity of the equipment. Place the device in the designated location and adjust its horizontal and vertical positions. 3. **Installation and Fixing**: Install the compressor firmly on the prepared foundation in accordance with the design drawings and the manufacturer’s requirements. Foundation bolts are usually required to secure the equipment and ensure its stability. 4. **Connect piping and electrical systems**: Install the pipes related to the intake, exhaust, and cooling systems. At the same time, wiring work for the electrical circuits is carried out, including connections to the control system and power supply. 5. **Installation of shaft end seals**: A trial seal is used during the initial installation, and once the equipment has been tested individually, it is replaced with a proper dry gas seal. This step is crucial for ensuring the reliability of the compressor’s long-term operation. 6. **Inspection and Testing**: After completing all the installation steps above, conduct an inspection of the system to ensure that all components are installed correctly and there are no defects. Then, a no-load test run is carried out to check the operating condition of the compressor, such as whether vibration, noise, temperature, etc., are within normal limits. 7. **Debugging**: Based on the test results, make the necessary adjustments to the compressor to ensure it meets the designed operating conditions. 8. **On-site inspection**: Finally, relevant personnel conduct an on-site inspection to ensure that the installation quality meets the standards, after which it is put into formal use. Each step must be carried out strictly by professionals to ensure the quality and safety of the installation. .

Thank you so much for the very detailed information

Regarding fixing with spot welding of the alignment studs, does it mean that after alignment is completed, the studs are directly welded in place? And what about making adjustments later on?

After the secondary grouting of the base, it is embedded in concrete; any subsequent adjustments are made at the bolts that secure the cat paw to the base

If possible, could you share the full version? Steam purging, oil circulation, and so on

Hello, Engineer Liu. I would like to ask what is the general sequence for tightening the mid-plane bolts – should we tighten those near the dry gas seal first? What percentage of torque should be applied on the first attempt?
