摘要：In this paper,volumetric losses in a positive displacement pump supplied with water and mineral oil are described and compared.The experimental tests were conducted using a prototype of a satellite pump (with a non-circular tooth working mechanism).In this paper,the sources of volumetric losses in this pump are characterized.On this basis,a mathematical model of these losses has been presented.The results of the calculation of volumetric losses according to the model are compared with the results of the experiment.Experimental studies have shown that the volumetric losses in the water pump are even 3.2 times greater than the volumetric losses in the oil pump.It has been demonstrated that the mathematical model describing the volumetric losses both in the water pump and in the oil pump is quite good.It has been found that the results from the loaded pump simulation (at ∆p=25MPa and ant n=1500rpm) differ from the results of the experiment by no more than 5% both for oil and water.
