Installation process of propylene refrigeration compressors
Thread Content
Here is a presentation of the installation process for a set of propylene refrigeration compressors. The motors drive these compressors; the gearbox and the compressor do not share a common base – the motor has its own base, while the compressor features a horizontally split structure. After mechanical testing in the factory, anti-rust oil is applied to all components. During on-site installation, it is necessary to open the compressor casing for cleaning, and a test seal is installed for oil circulation and individual unit testing. Once oil circulation and individual unit testing are successful, a dry gas seal is installed in place of the test seal.
1. Inspect equipment and components: Upon receiving the equipment, first check whether components such as the propylene refrigeration compressor, motor, and gearbox are intact, and ensure that all components have undergone mechanical testing in the factory and have been coated with rust preventive oil. 2. Install bases: Install separate bases for the motor and the compressor, ensuring that the bases are stable and properly aligned. 3. Install the motor: Place the motor on its base and secure it with bolts, making sure the connection between the motor and the gearbox is proper. 4. Install the compressor: Place the compressor on its base, making sure that the horizontal partition is aligned precisely. 5. Cylinder cleaning: Perform the cylinder cleaning process on-site, carefully cleaning the interior of the compressor to remove any impurities or residual rust preventive oil. 6. Install test-running seal: The test-running seal is installed for oil circulation and individual unit testing to ensure that the sealing device is installed correctly with no leaks. 7. Conduct oil circulation and individual unit testing: Start the system to carry out oil circulation tests to ensure that all components are functioning properly, and then perform individual unit testing to verify the performance and stability of the compressor. 8. Replace the dry gas seal: After successful testing, replace it with a dry gas seal to prepare for official operation. 9. Final inspection: Conduct a final check of the entire system to ensure that there are no leaks at any connections and that the system parameters meet the design requirements. 10. Official commissioning: Once all installation and testing tasks are completed, the propylene refrigeration compressor can be officially put into operation. By following these steps, the proper installation and optimal operation of the propylene refrigeration compressor can be ensured. .
For this split-type design, is the dry gas seal installed on the shaft first, and then is the rotor placed into the lower housing?
The dry gas seal is also part of the final assembly; what is installed now is a test seal, which will be replaced with a dry gas seal after individual unit testing
