摘要
设计制造和安装使用的经验认为，斜井抽油机设计中应优先采用后置式游梁抽油机的结构形式；支架应采用向前倾斜１０°、２５°和３８°三种结构并用销轴确定三个安装位置；连杆长度应有九种供选择；
In the design of slant hole pumping unit, the form of back-mouned beam pumping unit should be adopted preferen tially; three kinds of frameworks with 10°, 25°and 38°top rakes should be adopted and their locating positions should be determined by using the pin; there should be nine kinds of pitman lengths to be selected; fan-shapod crank should be se lected and thrss groups of crank pin holes should be provided to make both the balance torque and balance phase ad justable. By adopting combinatively the above-mentioned measures, the requirements for balance adjustment of such three groups of inclination angles as 5° ~ 18°, 19° ~ 31°and 32° ~ 45° can be satisfied. Matters that should be paid attention to in the design of the four-bar linkage on a slant hole pumping unit are discussed, and the calculation method for the geo metric design of the framework is presented.
