Embodiment Construction
[0007] The implementation of the present invention will be described below in conjunction with the accompanying drawings.
[0008] As shown in the figure: the combined transmission provided by the present invention is composed of a motor 1, a hydraulic coupling 2, a shaft coupling 3, a transmission 4, a speed reducer 5, a transmission shaft 6, and a pumping unit 7, and its structure and assembly relationship are as follows: The output end of the motor 1 is connected with a hydraulic coupling 2, and the hydraulic coupling 2 is connected to the transmission 4 and the reducer 5 through the coupling 3, and the output end of the reducer 5 is connected to multiple pumping units 7 connected in series through the transmission shaft 6. connect. Wherein, electric motor 1, coupling 3, speed changer 4, speed reducer 5 all can adopt the corresponding product, parts that adopt when producing single pumping unit at present. Hydraulic coupling 2 adopts a special hydraulic coupling for pumpin...

The present invention relates to a multiple oil pumping machines phase balanced combination transmission apparatus used in oilfield oil pumping well especially multi-well cluster production, which consists of an electric motor 1, a hydraulic coupling 2, a shaft coupling 3, a speed-changer 4, a reducing gear 5, a transmission shaft 6 and an oil pumping machine. Said transmission mechanism is of novel design and professional design. By adopting the combination transmission in accordance with the present invention, one electric motor can be used to drive a plurality of oil pumping machines to work without increasing motor capacity, and the reasonable balancing can be realized without counterbalance weight setting, and the oil pumping machine is ensured to achieve its favorable operating status. Adoption of said transmission mechanism can realize that a plurality of oil pumping wells uses only one electric motor and a set of speed-changer and reducing gear, then not only saves electrical machine and electric energy, but also simplifies the oil pumping machine structure, favoring reducing production costs and greatly improving economic performance.
Description
Technical field: [0001] The invention relates to a machine used for the production of oil pumping wells in oil fields, especially cluster well groups, belonging to the category of oil production machines. Background technique: [0002] The beam pumping unit is the most widely used traditional oil production machinery and equipment with the longest application history in oilfields at home and abroad. For a long time until now, this kind of oil extraction machinery all is to drive a pumping unit work by an electric motor. Due to oil well production and oil pumping conditions, the motor power configuration of the pumping unit is large, the no-load rate is high, and the power factor is low, resulting in "big horse-drawn carts" and energy waste. In order to solve the problem that the load of the sucker rod string and the pumping unit changes greatly and the work is unbalanced, a single pumping unit usually adopts the mechanical balance of the machine, such as crank balance, beam...
