As there is not any area in petroleum industry where the pumps wouldn’t be used, the further improvement of their technical and economic indicators remains to be the main problem of petroleum industry.The axis of crank shaft, the construction of which is represented by us, is shifted down relatively to axis of piston on purpose of transverse force’s reduction which affects the piston’s slider during the work of pump. The quantity of deflection e will be optimal when the transverse force Fy, which is represented in fig. 1, is a minimum share of maximum axial working force Fxmax.
This paper introduces using the formulas for defining value of eccentricity e. The results of calculations are given in graphs.These graphs indicate firstly that the value of transverse force Fy during the tact of injection changes smoothly and passes through a maximum, secondly, the disposition of this maximum doesn’t correspond to the angle ϕ = 0,5π, when the eccentricity of crank directed vertically and shifted toward the corner ϕ > 0,5π.
So the optimal displacement e is 45% of the crank displacement radius.Our research shows that with the displacement of crank axis relatively to the piston axis on 45% of crank radius transverse forces will be the least at the absolute value and will be directed to the different sides during the injection tact with the same maximum value.
