Requirements for the use of Marine supercharger lubrication systems

1. Marine supercharger uses engine oil for lubrication, the oil needs to reach CD level or above, and must be filtered by full-flow filter, filter size is less than 20u.

2. Turbine supercharger must be lubricated in advance under the following circumstances: downtime is too long or winter; After lubricating oil replacement or repair (including draining lubricating oil).

3. In the engine, within 3 to 4 seconds after starting, the oil inlet of the supercharger needs to display 69+69 kpa(0.7 kgf/cm2) oil pressure.

4, when the engine is running with load, in the Z high torque condition and above, the oil pressure at the supercharger inlet should be in the range of 196-392kpa(2.11-4kgf/cm2), and not less than 69kpa (0). 7 kg force per square centimeter).

5. The inlet temperature of lubricating oil should be lower than 100 ° C, and the Z height should not exceed 120 ° C

6. Do not use liquid seals and gaskets, and do not use sealants.

7. Avoid starting the total speed operation zone for a long time not exceeding 20 minutes).

9. Before the engine oil pressure is established, the total speed of the engine must be maintained (3 to 5 minutes).

10. Before the engine stops, its temperature and speed should be gradually reduced from the Z value (3 to 5 minutes).
