High speed titling-pad bearing
Adopt horizontal split-type tilting-pad bearing which made by material of ISI 1040 carbon steel (inner) and babbitt alloy (surface), when the speed load changes, the bearing diagonal block is automatically centered, this automatic adjustment function can ensure the machine’s smooth operation.
Efficient removable cooler and intake air adjustment
The cooler is separated from the gearbox, and the lubrication system is perfectly separated from the compressed air, ensuring that the compressed air is 100% clean and oil-free. Removable cooler, tube bundles is precisely matched with the finished shell, which can effectively improve the heat exchange rate between compressed air and water and reduce the consumption of cooling water.
By adjusting the installation angle of inlet guide vane of the impeller, the pre-rotation of airflow can be adjusted within a range of 70-105%.
Impeller dynamic balance test
Using advanced dynamic balance testing equipment, according to the requirements of “SUCCESS ENGINE Dynamic Balance Test Procedure”, a strict dynamic balance testing is carried out on each impeller and shaft assembly to ensure the balance and stability during high-speed operation.
Advanced large-screen PLC monitoring system
Large LCD display control screen, real-time monitoring of equipment operation, shutdown information, perfectly combined the surge control and energy saving optimization, complete automatic alarm & protection functions, advanced and mature control system, guarantee the compressor system stability and ease of operation.
Strict manufacturing process
