Seawater hydraulic piston pump has been widely used in ocean engineering and become a key power component for underwater equipment due to its inherent characteristic such as energy conservation and environment friendly. As one of the most important properties of seawater hydraulic piston pump, vibration would further determine the stability, reliability and stealth of underwater equipment. In this paper, the dynamic of a novel crankshaft seawater piston pump with gearbox are analyzed theoretically, illustrating the dramatically effect of the gearbox on the vibration characteristic of the seawater hydraulic piston pump. Then, a new type crankshaft seawater hydraulic piston pump system driven by a permanent magnet synchronous motor instead of asynchronies motor is proposed in order to eliminate the gearbox and improve the vibration characteristics. In addition, the vibration characteristic of this new type crankshaft seawater hydraulic piston pump system driven by asynchronous motor and permanent magnet synchronous motor are studied and compared experimentally. The experiment results indicate that the seawater hydraulic piston pump system driven by permanent magnet synchronous motor eliminating the gearbox has lower vibration acceleration level in comparison with the pump system driven by asynchronous motor and gearbox. The vibration acceleration level can be reduced from 7dB to 4.3dB. Driving the seawater hydraulic piston pump by permanent magnet synchronous motor instead of asynchronous motor is of benefit to eliminating the gearbox and reducing the vibration excitation source. Consequently, the vibration characteristic of the seawater hydraulic piston pump system driven by a permanent magnet synchronous motor is significantly improved.

A water lubricating axial piston pump (WLAP) is one of the key components in water hydraulic systems. However, the characteristics of water, including low viscosity, strong corrosiveness, and easy vaporization, results in the increase of friction and wear of pairs, and the increase of temperature. Compared with oil pumps, the thermodynamic characteristic of WLAP is more serious. In this paper, the integrated thermodynamic model of WLAP, which includes heat generation of pairs and heat conduction of water and air, is established to improve pump design. The calculation results show that the water temperature of WLAP exceeded 90 ℃, and the pump could not work normally in extreme conditions (the inlet water temperature and ambient temperature are both 50 ℃). Consequently, a cooling design of WLAP, which circulates the inlet water in the pump chamber, is carried out. Then, the thermodynamic model was modified. Based on this model, the temperature rise characteristics and heat dissipation characteristics of the WLAP are analyzed. The steady-state water temperature of pump shell under extreme conditions is obtained. The temperature sensors and a thermal imaging were used to measure the temperatures of the WLAP. The results indicate that the water temperature of WLAP decreases significantly. The difference of the steady-state temperature of WLAP between simulation and experiment is less than 4 ℃, and its temperature distribution is uniform. Therefore, the cooling design of WLAP is effective and it can work normally under the maximum speed and pressure in extreme conditions.

Premature failure due to abrasive wear is observed in high powered engine in recent decades, despite of stringent maintenance procedures comparative to older engine. Plasma spray coatings are recurrently used to circumvent the abrasive wear in aerospace, defense and certain automotive applications like piston pump, cylinder bore etc. This work is to identify the most influencing wear parameters namely sliding speed (SS), applied load (AL) and sliding distance (SD) of the composite coated steel. Initially the surface morphology and elemental analysis was carried out to analyze the surface roughness and homogeneous distribution of the composites. Furthermore wear analyzes results indicates that the composite coating has high wear resistance and specific wear rates are ranging from 0.52346 × 10-5 m 3 / N-m to 3.25711× 10-5 m 3 / N-m
