THE INFLUENCE OF WATER AND MINERAL OIL ON MECHANICAL LOSSES IN THE DISPLACEMENT PUMP FOR OFFSHORE AND MARINE APPLICATIONS
Abstract
In this paper mechanical losses in a positive displacement pump supplied with water and mineral oil (two liquids having significantly different viscosity and lubricating properties) are described and compared. The experimental tests were conducted using a special design (prototype) of a satellite pump. The design of the satellite pump is presented in the article. The pump features a non-circular tooth working mechanism. This pump was developed to work with both water and mineral oil. In this paper the sources of mechanical losses in this pump are also characterised. On this basis, a mathematical model of these losses has been developed and presented. The results of the calculation of mechanical losses according to the model are compared with the results of the experiment. Experimental studies have shown that the mechanical losses in the water pump are even 2.8 times greater than the mechanical losses in the oil pump. It has been demonstrated that the mathematical model describes the mechanical losses both in the water pump and in the oil pump well. It has been found that the results from the loaded pump simulation (at p=25MPa) differ from the results of the experiment by no more than 5% both for oil and water
