眼镜板、切割环等磨损件，经过不断的技术攻关，使用寿命长，最佳泵送状态时，其寿命可达3万方。
The wearing parts, such as the anti-wearing plate and the cutting ring , have a long service life up to 30000 m3 under favorable condition .
研究表明，流量、扬程、轴功率和效率切割指数具体数值都与普通清水离心泵不同。
The results show that the values of the flow rate, head, shaft power and efficiency trim exponents differ from existing trim exponents for normal centrifugal water pumps.
输送水时，叶轮切割后，泵的扬程、轴功率、效率都下降。
When pumping water, the head, shaft power and efficiency of the pump decrease with the reducing in impeller diameter.
