The function of T- NA series turbo service kits:

The quality of the overhaul kits or service kit or repair kit or rebuild kit is very crucial for the turbocharger maintenance, because the poor quality or too cheap service kits could misshape or degrade quickly and causing even more damage on the turbocharger.​

Brief introduction of Marine turbocharger:

The marine turbocharger, also known as exhaust gas turbocharger, is the main equipment in the diesel engine boosting system. It consists of a single-stage exhaust gas turbine and a centrifugal compressor. Exhaust gas turbochargers operate at high speeds, high exhaust gas temperatures, high air and exhaust gas flow rates, and high flow rates. Generally, the pressure of the exhaust gas is 0.25-0.45 MPa, and the exhaust gas temperature is 500-600 °C. The speed varies with the size of the Marine turbocharger / supercharger. The maximum speed of the large-sized supercharger is 10000 r/min, and the maximum speed of the small-sized supercharger can reach 40,000~50000r/min. Therefore, the marine turbocharger / exhaust gas turbocharger is a precision machine.

When the diesel-exhaust turbocharger combination is in operation, the marine turbocharger/exhaust gas turbocharger is prone to failures such as turbine casing corrosion, bearing damage, blade damage, gas seal damage, and supercharger vibration. The daily good maintenance management can reduce these failures.
