Novel seawater hydraulic axial piston pump and its experiment
Most water hydraulic axial piston pumps in service are swashplat-slipper pumps, but large lateral forces exist between their pistons and cylinder bores, which may lead to the phenomena of partial wear and even locking to death. To avoid this disadvantage, a novel seawater hydraulic axial piston pump with swashplaterod stye structure has been put forward. Compared with traditional swashplat-slipper pumps, it can reduce lateral force between piston and cylinder bore more than 90％ of the former, thus improves the work condition in cylinder bore and piston pair greatly and extends its service life effectively. Subsequently, a series of experiments have been carried out on the test rig. The results show that swashplate-rod water hydraulic axial piston pump has excellent and steady performance during long term operating tests, which has the prominent merits of large flow rat, high system pressure, small volume, excellent suction, high reliability and so on.
