| Zusammenfassung: | The invention discloses an oil drilling mud pump. The oil drilling mud pump is characterized in that the mud pump adopts a conversion mechanism composed of a power shaft and an inclined disc, wherein the power shaft is connected with the inclined disc through two symmetric flat keys, and the inclined disc is supported by utilizing the center of a central sphere as a fulcrum. The conversion mechanism can drive at least two cylinders, one end of each piston rod is connected with the inclined disc, and the other end is connected with one piston. An L-shaped sealing ring is arranged at the bottom of each piston. The oil drilling mud pump can reciprocate and is small in size, light and high in efficiency. |
