Type of intelligent pumping unit

Abstract

The invention discloses a new type of an intelligent pumping unit, including a counter weight box whereas a first driven sprocket is provided on a top inside of said counter weight box and a second driven sprocket is provided at a bottom inside of said counter weight box, and a pedestal whereas an electric motor and a reducer mounted thereto; the reducer, with a driving sprocket connected on its output shaft, is driven to rotate by the electric motor via a belt.

We claim: 
     
         1 . An intelligent pumping unit, comprising a counter weight box, wherein a first driven sprocket is provided on its top inside and a second driven sprocket is provided at a bottom inside of said box. 
     
     
         2 . The intelligent pumping unit according to  claim 1 , further comprising a pedestal mounted with an electric motor and a reducer; the reducer, with a driving sprocket connected on its output shaft, is driven to rotate by the electric motor via a belt. 
     
     
         3 . The intelligent pumping unit according to  claim 2 , wherein a second driven sprocket is connected with the driving sprocket via a chain. 
     
     
         4 . The intelligent pumping unit according to  claim 2 , wherein said pedestal is installed with a rack, whereas a roller mounted on a platform on the top of the rack, and the roller is winded up with a load belt. 
     
     
         5 . The load belt according to  claim 4 , wherein one end of said load belt is connected to the counter weight box and another end is connected to a sucker rod. 
     
     
         6 . The intelligent pumping unit according to  claim 4 , wherein a transitional sprocket is mounted on the top inside of the rack, whereas said transitional sprocket is connected to the driving sprocket and the first driven sprocket via the chain.
