8. energy-saving type beam pumping unit as claimed in claim 6 is characterized in that: described belt (20) internal surface is provided with belt teeth, and described motor pulley (11) and big belt pulley outer surface are provided with and the suitable gear teeth of described belt teeth.
9. as each described slide beam energy-saving type pumping unit of claim 6 to 8, it is characterized in that: be provided with the fluid power gear between described motor (10) and the motor pulley (11).
10. energy-saving type beam pumping unit as claimed in claim 9, it is characterized in that: described fluid power gear is the torque converter (15) that is provided with four different gears, its control electromagnetic valve is electrically connected with electric control box (70), and described electric control box (70) is provided with the gear control panel.
11. energy-saving type beam pumping unit as claimed in claim 9 is characterized in that: also comprise proximity detector (72); This sensor (72) is electrically connected with electric control box (70); Detect the diverse location of described crankshaft balance weight (61) by described proximity detector (72), control the rotating speed that described torque converter (15) is regulated described big belt pulley (30) by electric control box (70) immediately, thereby adjust oil well pump (90) up-downgoing jig frequency.
