ABSTRACT

The Influence of Water and Mineral Oil on Volumetric Losses in the Displacement Pump for Offshore and Marine Applications

“…4), which also play the role of compensation plates. Thus, the satellite pump has the ability to compensate axial clearances of the rotor and the satellites [20,[22][23][24][25][26][27][28].…”

“…Q -effective flow of pump; Fig.4. High pressure commutation plate (left) and suction commutation plate (right) [20,[22][23][24][25][26][27][28] Experimental studies of the pump PSM-0,75/15 were carried out using the following liquids:…”

“…Thus, in order to eliminate the pollution of the environment and marine waters, it seems reasonable and justified to eliminate oil systems and replace them with water systems. To this end, it is necessary to develop and test innovative components for hydraulic water systems [20][21][22][23][24][25]. Thus, it was reasonable to develop a new positive displacement water pump called the satellite pump and mark it with the PSM symbol.…”

“…Thus, it was reasonable to develop a new positive displacement water pump called the satellite pump and mark it with the PSM symbol. The pump contains an innovative operating mechanism consisting of non-circular gears [20,[22][23][24][25][26]. The construction of this pump is described in the next section.…”

Problems of the Starting and Operating of Hydraulic Components and Systems in Low Ambient Temperature (Part V)

“…In each of those components energy losses take place, which are defined as volumetric, pressure and mechanical losses. Exact values of these losses for a given hydraulic device are determined in steady-state conditions, neglecting, as a rule, the effect of heat transfer inside the device on the total energy loss balance [13,14,[16][17][18][19][20][21][22]25]. During the hydraulic machine start-up, the heat transfer between the working medium and machine elements affects significantly the efficiency of energy conversion in this machine, especially in the case of cold machine supplied with hot working medium, which was proved in [3][4][5][6][7][8][9][10], among other sources.…”
