【摘要】 目前，我国工业清洗发展很快，大型高压水射流多功能清洗设备的用量日渐增多，并在清洗行业中的作用越来越大。但是，在使用中，普遍存在着压力和流量不合理、高压水泵能量利用率低、高压管路压力损失过大、喷枪、喷头涡流严重等弊病，为解决上述问题进行了提高高压水射流清洗效率的研究工作。更多还原

【Abstract】 Nowadays, the amount of multi-function cleaning equipment of large high pressure water jet used in cleaning industry of this country has been increasing everyday, showing that the equipment is more and more effective. However, in general practice, there are lots of malpractice which severely hinders to widen the application of this technique, such as the inappropriate selection of the pressure and volume, inefficient use of the high pressure pump, too much pressure loss in the pipeline and the eddy loss of the spray gun and nozzle. In order to solve these problems, several methods for improving the efficiency of high pressure water jet cleaning are discussed更多还原
