To solve this problem, we must cut and discharge the impurities and long fibers inhaled by the slurry pump, and then pump out the dirty sand and water together. This not only extends the service life of the slurry pump, but also creates conditions for accelerating the construction speed of municipal engineering. There is also a stirring type electric pump, its role is slightly different from the incision. It is equipped with stirring organization accessories. When pumping to the bottom, because the underwater sediment or sediment reaches a certain concentration proportion and is uneven, the water will be sucked in by thick sediment before it is drained. Therefore, it is necessary to mix them evenly and dilute them into thin sediment, so that it is not easy to damage the electric pump.
别的为了坚持主叶轮轴向力的平衡，须设置一个副叶轮结构，它能下降密封腔的压力，使电泵的轴向力及机械密封的寿数均大大提高。关于电泵的散热问题向来是电泵使用寿命的关键问题，如果散热作用欠好，电机内温度将升高，使电动机的功率不断升大，容易将电机烧坏，缩短了泵的使用寿命。为了处理这个问题，我们选用外循环冷却系统，来增强散热功能，它能确保当电泵显露水面时，还能正常工作。关于排送腐蚀性较严峻的液体时，可先用不锈的电泵，它的耐腐性，和运用可靠性将有很大程度的提高In addition, in order to maintain the balance of the axial force of the main impeller, it is necessary to set up a secondary impeller structure, which can reduce the pressure of the seal chamber, so that the axial force of the electric pump and the service life of the mechanical seal are greatly improved. The heat dissipation of the electric pump has always been the key problem of the service life of the electric pump. If the heat dissipation is not good, the temperature in the motor will rise, so that the power of the motor will continue to rise, and it is easy to burn the motor, which shortens the service life of the pump. In order to deal with this problem, we choose the external circulation cooling system to enhance the heat dissipation function, which can ensure that when the electric pump is exposed to the water, it can work normally. When the corrosive liquid is discharged, the stainless electric pump can be used first. Its corrosion resistance and operation reliability will be greatly improved.
