小泵站装置效率是综合反映抽水设备及泵站各部分效率的技术经济指标,因此,提高抽水设备及泵站各部分效率是提高装置效率的重要途径。 一、提高水泵效率 水泵的损失功率主要有三部分:一是机械损失功率;二是容积损失功率;三是水力损失功率。如何提高水泵效率可采取以下措施予以补救。 (一)搞好扬程配套。对离心泵、混流泵可采用变速或车削叶轮进行调整,对轴流泵可采用变速、变角进行调整,也可以采用更换叶轮或换泵来解决。 (二)提高叶轮表面光洁度。可采用砂轮磨去叶片正、反两面或前后盖板表面的粗糙粒,并用油石磨光后组装。
The efficiency of a small pump station device is a technical and economic indicator that comprehensively reflects the efficiency of each part of a pumping plant and a pumping station. Therefore, improving the efficiency of pumping stations and pumping stations is an important way to improve the efficiency of the pumping station. First, to improve the efficiency of the pump The loss of the pump has three main parts: First, the mechanical loss of power; second is the volume loss of power; third is the hydraulic loss of power. How to improve the efficiency of the pump can take the following measures to be remedied. (A) do a good job supporting head. Centrifugal pumps, mixed flow pump can use variable speed or turning impeller to adjust the axial flow pump can be used variable speed, variable angle to adjust, you can also use the replacement of impeller or pump to solve. (B) to improve the surface finish of the impeller. Wheel grinding can be used to remove the blade is positive and negative on both sides of the rough surface of the cover tablets and polished with whetstone assembly.
