In order to provide reliability. reproducibility. objectivity of solid particle separation performance test on marine centrifugal purifier, an investigation had been done on solid test dusts. test standards and designation of a definite standard test dust In test specifications or standards. ISO 121031-1 A2 test dust is the best test particle to meet commercial and military fuel oil and lube oil requirements on marine standards.

An improvement of burning damage on a couplingless type marine fire pump is studied. The pump consists of an induction motor, a pump-motor shaft and a volute type impeller. The burning damage had occured after changing the material of the pump-motor shaft from SM45C to STS316 for improving anti-corrision properity in sea water. It is shown that a material change on the pump-motor shaft can cause motor burning in the process of pump development stage. It can be solved by increasing the efficiency of the motor.

In order to estabilish a criteria of solid particle separation performance test on marine centrifugal purifier at fatory acceptance test, an investigation had been done on criteria of test standards, regulations and test specifications of purifier manufactures. KS V 7836, fuel oil and lubicating oil purifiers for marine use-centrifugal type, the criteria of solid particle separation is studied in the point of reality, restricts and analysis method. It is proposed that a reasonable criteria and analysis method should be adopted, and the current criteria shall be revised to adequate levels considering reasonable basis and industrial technology levels. Also, the test analysis conceptions, separation efficiency method and particle size restriction method, are reviewed to fulfil separation performance test for marine centrifugal purifiers.

In order to provide reliability, reproducibility and objectivity of solid particle separation on marine centrifugal purifier performance test, an investigation had been done on solid test dusts, test standards and designation of a fixed type test dust in test standards KS V 6611. ISO 121031-1 A2 test dust is the best test particle to meet commercial and military fuel oil and lube oil requrements on marine standards.
