[". 이중성 泵效率的问题

api6111泵的效率偏差有规定吗 因为泵没做之前都只是一个估算效率。第二个问题是老旧电机会不会对泵的效率有些影响?第三个问题是大马拉小车的话会不会影响泵的效率呢?

제시하신 문제들은 모두 문제들이 아닙니다 첫째, 추정 효율은 회사의 선택 자료와 테스트 데이터를 바탕으로 예측된 효율이며 오차는 크지 않으며, 전기기의 출력은 여유가 있습니다; 둘째, 전기기가 오래되면 효율이 약간 떨어지지만 적절한 유지보수를 하면 전기기의 효율은 떨어지지 않으며 寿命还很长;第三你多虑了

泵的效率怎么会有偏差呢?与电机无关,只要不超过电机功率就欧了

离心泵的效率主要考虑容积损失、水力损失和机械损失三方面 在泵转速、流量不变情况下 密封环无磨损、流道表面无变化 运行平稳 通常情况下 效率一般是不会变的。
