Double-driving non-contact transmission vertical oil sucking machine

Abstract

The invention provides a double-driving non-contact transmission vertical oil sucking machine, and belongs to a novel field of mechanical-electrical integration application. The double-driving non-contact transmission vertical oil sucking machine comprises a double-driving four-safety speed reducing machine, an electric machine moving device and a digital intelligent controller, wherein the double-driving four-safety speed reducing machine is arranged on a top platform of a machine frame, the electric machine moving device is arranged on a base of the machine frame, the digital intelligent controller is externally connected with a sensor and is arranged in a control cabinet arranged at the lower part of the machine frame, the winding end in a driving wheel rope groove of the double-driving four-safety speed reducing machine suspends an oil well load through a front movable pulley, the other end suspends a driving rope of an anti-falling counterweight through a back movable pulley, and a protection rope with the other end connected with the anti-falling counterweight is fixedly arranged in a protection rope groove. The double-driving non-contact transmission vertical oil sucking machine has the advantages that the oil seepage is avoided, the maintenance-free effect is basically realized, the non-contact transmission is adopted for protecting the equipment, the energy is saved, the environment is protected, and safety, reliability, intelligence and high efficiency are realized. The double-driving non-contact transmission vertical oil sucking machine can be widely applied to oil extraction of the vertical oil sucking machine and other lifting operations requiring frequent direction change.

Description

technical field [0001] The invention is a double-drive non-contact transmission vertical pumping unit, which belongs to the new application field of electromechanical integration. Background technique [0002] Petroleum is the blood of industry and an extremely important strategic material. Due to the irreplaceable strategic position of oil in the national economy and national defense construction, it is necessary to use more efficient oil extraction machinery to extract as much oil as possible. [0003] The main means of oil production are four-link beam pumping unit and balance-balanced vertical pumping unit. According to incomplete statistics, there are about 2,000,000 oil wells in the world at present, of which the mechanical oil recovery of pumping units accounts for more than 95%. [0004] The traditional four-link beam pumping unit has been used for more than 120 years and has the advantages of being strong, reliable and durable. Although the model is constantly im...

AI Technical Summary

Problems solved by technology

[0006] Most of the reducers used in mechanical oil recovery are shaft-end symmetrical output. Due to the continuous operation of 24-hour alternating load and high torque all year round, the failure rate of conventional reducers is relatively high, and all of them have oil leakage, which affects the oil recovery rate. It is difficult to maintain, and there is an urgent need for deceleration equipment with better performance to optimize oil production machinery
