随着我国经济的快速发展，高效率、高清洁度已成为许多生产企业的重要指标。经研究发现，钢板的表面清洁程度一直是影响产品质量的一个重要环节。钢板在进入生产线之前对钢板表面进行清洗对提高产品质量至关重要，北京德高洁清洁设备有限公司经过大量试验，终推荐采用DP 280/74EM高压清洗机用以解决钢板在进入生产线前的清理问题。然而，使用DP 280/74EM高压清洗机在钢板清洗应用中，错误的选择射流角对水射流打击力有很大的影响。
在流量一定的情况下，射流角可以影响钢板表面高压清洗机的水射流打击力。试验表明，在相同的情况下，射流角从40°减为26°，水射流打击力可以提高58%；同样，射流角从40°减为30°，水射流打击力可提高36%，射流角从30°减为26°，水射流打击力可以提高16%。当然，这些水射流打击力的增加只是理论值而已，因为实际上，减小射流角表示需在喷射集水管上增加喷嘴数量，所以还要分析因射流角减小带来的水射流打击力增加以及因流量减少带来的水射流打击力减小，后以水射流打击力的增加来确定喷嘴的射流角才是正确的。(图/文www.wxcwjx.com)

With the rapid development of our economy, high efficiency, high cleanliness has become an important indicator of many production enterprises. The study found that, surface cleanliness steel plate has been an important part of product quality. Steel plate before entering the production line of steel plate surface cleaning is essential to improve the quality of the products, Beijing digcher Cleaning Equipment Co., Ltd. after a lot of tests, the final recommendation is used to solve the plate in the cleaning problem into the production line adopts DP 280/74EM high pressure cleaning machine. However, DP 280/74EM high pressure cleaning machines used in the steel cleaning applications, choose the wrong angle on jet water jet impact force has a great influence.
Under the same flow the water jet, jet angle can influence the plate surface of high pressure cleaning machine blow force. Experiments show that, under the same conditions, the jet angle from 40 ° to 26 °, water jet impact force can be increased by 58%; similarly, jet angle from 40 ° to 30 °, water jet impact force can be increased by 36%, the jet angle from 30 ° to 26 °, water jet impact force can be increased by 16%. Of course, the water jet impact force increases is the theoretical value, because in fact, reduce the jet angle increased number of nozzle in spray water pipe, but also because of water jet jet angle decreases impact force increases as well as reduced flow brings water jet impact force is reduced, increasing the water jet impact force to determine the nozzle jet angle is correct.
