动力还包括电动机，对轮或胶带轮联轴器等，耐磨件还包括衬板轴套等，密封件包括轴封、副叶轮等，支撑件包括支架等，但内部原理是一致的，当叶轮快速转动时，叶片促使介质很快旋转，旋转着的介质在离心力的作用下从叶轮中飞出，泵内的介质被抛出后，叶轮的中心部分形成真空区域，介质在大气压力（或水压）的作用下通过管网压到了进料管内。这样循环不已，就可以实现连续供料，从而达到工艺设计要求的扬程和流量。当然，入料方式目前多采用压入式，即料位高于入料管，则可以减去从上水管或泵壳向内部灌水的步骤。

三﹑易驱CV3300变频器特点

1）高精度可达正负0.5%，转矩响应快<20ms；

2）低频力矩大，开环矢量模式下，可实现0.5HZ带载150%运行；

3）重负载过载能力，150%额定负载1min，180%额定负载3S；

4）逐波限流功能，能将电机电流限制在某一水平同时不影响输出转矩；

5）工作电压范围宽，额定电压380~440V；

6）独立风道，并外加防护网设计，防止纱线堵塞，环境适应能力强；

7）过流、过压、短路、缺相、欠压等多种全面的保护，有效保护电机。
