水工业机械设备现状分析

本文简要介绍了我国通用和专用水工机械在污水处理、给水排水方面的应用现状，介绍了新产品、新技术的研究应用进展，并与国际先进水平进行了比较。

我国水工业机械设备的总体状况与发展

水工业机械设备分为通用机械设备和专用机械设备两大类,通用机械设备主要有泵类、阀类、风机类。专用机械设备是水工业设备自身研制的重点,包括拦污机械设备、除砂及刮泥设备、曝气及搅拌设备、投药及消毒设备、浓缩及脱水设备、氧化脱盐设备等。近年来,又增加了膜处理设备、沼气利用设备、序批法滗水设备。

Simulating System for the Investigation of Mechanical Malfunctions Appeared in a Twin AC Drive Used in Cement Industry

In order to investigate the dynamic behavior, to study a variety of operational problems, to apply different control techniques and to suggest functional improvements of a high power electromechanical system, a pilot study on a low power laboratory simulating system is proposed in this paper. Particularly, to investigate operational problems of a twin AC drive with asynchronous machines used for cement kilns, an under-scale laboratory simulating system has been developed and experimental results are being presented in this research work.
