Embodiment Construction
[0015] The constant power energy-saving multi-speed driving device includes a prime mover 1 and a transmission housing 2. A drive shaft 3 connected to the output shaft of the prime mover 1 and a main shaft 4 parallel to the drive shaft 3 are arranged in the transmission housing 2. On the drive shaft 3 Several driving gears 5 are fixed, and the main shaft 4 is provided with several driven gears 6 which mesh with each driving gear 5 one by one. There is a transmission assembly 8 that meshes with it and can mesh with the driven gears 6 on both sides. The output end of the main shaft 4 is provided with a tensioning coupling sleeve 9 that is interference fit with it. Pulley 10.

The invention particularly relates to a constant-power energy-saving multispeed drive device and solves the problem that the existing pumping units are high in power and energy consumption and has potential safety hazard. The constant-power energy-saving multispeed drive device comprises a prime motor and a speed change shell. A drive shaft connected with the output shaft of the prime motor and a spindle parallel with the drive shaft are disposed in the speed change shell. A plurality of drive gears are fixed on the drive shaft. A plurality of driven gears are disposed on the spindle, and each driven gear is meshed with the corresponding drive gear. A speed change gear fixed to the spindle is disposed between every two driven gears. A speed change assembly meshed with the corresponding speed change gear and with the driven gears on two sides of the speed change gear is disposed on each speed change gear. The output end of the spindle is provided with a tension connecting sleeve in interference fit with output end of the spindle. A belt pulley connected with the tension connecting sleeve through bolts is sleeved on the tension connecting sleeve. The constant-power energy-saving multispeed drive device is applicable to long-stroke and low-stroke-frequency pumping units of common oil fields, and energy consumption is lowered while potential safety hazard is avoided. In addition, the constant-power energy-saving multispeed drive device is simple in structure and high in mechanical efficiency.
Description
technical field [0001] The invention relates to a driving device for a pumping unit, in particular to a constant power, energy-saving and multi-speed driving device for a pumping unit in an oil field. Background technique [0002] At present, the number of pumping units in my country is more than 300,000, the total installed capacity of electric motors is 12,000 MW, and the annual power consumption is tens of billions of kW·h. The operating efficiency of pumping units is particularly low. The average operating efficiency in my country is 25.96%, and the average level abroad is 30.05%. The annual energy saving potential can reach several billion kW·h. [0003] After analyzing the stroke times of more than 130 kinds of beam pumping units produced by various manufacturers, type 3, type 4, type 5, type 6, type 8, type 10, type 12, type 14 and type 16, The maximum number of strokes averaged 8.48 times, the average number of intermediate strokes was 6.42 times, and the average nu...
