隨著我國經(jīng)濟(jì)的快速發(fā)展，高效率、高清潔度已成為許多生產(chǎn)企業(yè)的重要指標(biāo)。經(jīng)研究發(fā)現(xiàn)，鋼板的表面清潔程度一直是影響產(chǎn)品質(zhì)量的一個(gè)重要環(huán)節(jié)。鋼板在進(jìn)入生產(chǎn)線之前對鋼板表面進(jìn)行清洗對提高產(chǎn)品質(zhì)量至關(guān)重要，北京德高潔清潔設(shè)備有限公司經(jīng)過大量試驗(yàn)，終推薦采用DP 280/74EM高壓清洗機(jī)用以解決鋼板在進(jìn)入生產(chǎn)線前的清理問題。然而，使用DP 280/74EM高壓清洗機(jī)在鋼板清洗應(yīng)用中，錯(cuò)誤的選擇射流角對水射流打擊力有很大的影響。
在流量一定的情況下，射流角可以影響鋼板表面高壓清洗機(jī)的水射流打擊力。試驗(yàn)表明，在相同的情況下，射流角從40°減為26°，水射流打擊力可以提高58%；同樣，射流角從40°減為30°，水射流打擊力可提高36%，射流角從30°減為26°，水射流打擊力可以提高16%。當(dāng)然，這些水射流打擊力的增加只是理論值而已，因?yàn)閷?shí)際上，減小射流角表示需在噴射集水管上增加噴嘴數(shù)量，所以還要分析因射流角減小帶來的水射流打擊力增加以及因流量減少帶來的水射流打擊力減小，后以水射流打擊力的增加來確定噴嘴的射流角才是正確的。(圖/文vo123.cn)

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.
