Claims (1)
δ ≤ 0,5(δx-δd),
где
δ - максимальное отклонение оси трубы на базовой длине, по меньшей мере, равной осевой длине контактной поверхности плунжера насоса, мм;
δx - допуск на хонингование, мм;
δd - плюсовой допуск по внутреннему диаметру трубы-заготовки, мм,
а черновое хонингование производят инструментом, осевая длина которого равна по меньшей мере трем полупериодам кривой изгиба оси заготовки.A method of manufacturing a cylinder of a downhole sucker rod pump, including the manufacture of a calibrated tube billet, straightening its curvature, and roughing and honing the inner channel, characterized in that before honing, the actual curvature of the inner channel of the billet pipe is measured and corrected by its elastic-plastic anti-bending to the value of curvature, not exceeding
δ ≤ 0.5 (δ x -δ d ),
Where
δ is the maximum deviation of the axis of the pipe at a base length of at least equal to the axial length of the contact surface of the pump plunger, mm;
δ x - honing tolerance, mm;
δ d - plus tolerance on the inner diameter of the pipe billet, mm,
and rough honing is carried out with a tool whose axial length is equal to at least three half-periods of the curve of the bend of the axis of the workpiece.
