浙江漓渚铁矿以节能为目的,研制了LSZ5-29型射流真空泵。该泵根据流体力学原理,在冶金矿山系统首次采用拉阀尔喷管作引射-扩压器,提高了引射能力,促进了气水两相的均匀混掺、加速,减少了能量损失,从而使极限真空度和最大抽气量都有提高,并使尾管高度得到降低。经特性测试和工业生产试运行证明,该泵各项指标均达到设计要求。
Zhejiang Lizhu Iron Mine for the purpose of energy saving, developed a jet LSZ5-29 type vacuum pump. The pump according to the principle of fluid mechanics, the first time in the metallurgical mining system using pull-valve Seoul lance for the injection - diffuser, improved injection capacity, and promote the gas-water two-phase uniform mixing, acceleration, reducing energy loss, So that the ultimate vacuum and the maximum amount of exhaust have increased, and to reduce the height of the tail pipe. The characteristics of the test and industrial production test run proved that the pump indicators have reached the design requirements.
