Determination of the kinematic parameters of the new constructivesolution of the beamless sucker-rod pump

Abstract

The petrol industry has very big impact on the modern world economy and politics. With any options and scenarios for the development of the economy in the coming years, natural resources, especially fossil oil products, will be the main factor of world economic growth. The sucker-rod pumps are one of the important aggregates for the mechanized oil recovery on land. However, the low efficiency, the big expenditure of the electric power, an incomplete construction of driving gear and reformative mechanisms, impossibility of use in existing aggregates of electric motors with a rotation high frequency lead to research of more perfect construction of a mechanical drive pumps. The present study describes a new design solution for a beamless sucker-rod pump for oil production, characterized by small dimensions and metal consumption, less energy consumption, better dynamic characteristics. The results of analytical kinematical studies and numerical calculations of the new beamless sucker-rod pump are presented.
