基于气动潜水泵的结构特点,针对矿用气动潜水泵需要限制主轴转速的工作状况,提出了在泵的主轴上增加气动潜水泵自动控制机械结构,给出了解决限制主轴转速的控制结构的设计原理,经实际生产验证自动控制结构满足生产使用要求,且结构紧凑,生产成本低,可靠性好。 Based on the structural characteristics of the pneumatic submersible pump, aiming at the working condition that the submerged pneumatic pump needs to limit the rotational speed of the main shaft, a mechanical structure of the submersible pump on the main shaft of the pump is proposed. The design of the control structure for limiting the rotational speed of the main shaft is given Principle, the actual production verification automatic control structure to meet the production and use requirements, and compact structure, low production costs, good reliability.
