针对传统潜水电泵在沼气液料输送过程中存在的缺陷,研制了一种适用于沼气断状秸秆液料输送的新型无堵塞污水潜水电泵,解决了沼气液料输送过程中加料设备易堵塞、成本高和产气效率低等问题。该新型电泵具有良好的物料切割系统,切割装置在泵壳下端固定切割板上,切割板下端设有环状外切割刀,割刀中间设有旋转螺旋刀片,形成了对进口秸秆液料水平和垂直方向的切割作用;固定切割板上端面设有环状切割凹槽,叶轮旋转时对物料形成二次切割,使液料流动更流畅。潜水电机部分设计了内循环冷却装置,改变了传统潜水电泵不能长期在非潜水状态下使用的技术难题。
Aimed at the defects of traditional submersible pump in the biogas feed process, a new non-clogging sewage submersible pump which is suitable for conveying biogas cut off straws is developed to solve the problem that the feeding equipment is easily clogged , High cost and low gas production efficiency. The novel electric pump has a good material cutting system, the cutting device is fixed on the cutting board at the lower end of the pump shell, the annular cutting knife is arranged at the lower end of the cutting board, the rotating screw blade is arranged in the middle of the cutting knife, And the vertical direction of the cutting effect; fixed cutting plate with an annular cutting groove on the end face, the impeller rotation of the material forming a secondary cut, so that liquid material flow more smoothly. Submersible motor part of the design of the internal circulation cooling device, changing the traditional submersible pump can not be used for a long time in non-submerged technical problems.
