无缝钢管水压机排气头系统改进

Improvement in Exhaust Head System of Hydraulic Machine for Seamless Steel Pipe

介绍了无缝钢管厂水压机排气头系统存在的设计缺陷,并提出具体改进方案:将原阀杆和导向套之间镶嵌密封圈的密封方式,改进为在阀杆上内嵌铜套密封并将导向套底部封死的方式,同时改进水处理设施。运行结果表明,故障率大幅降低,提高了机组作业率。

The design defects existed in exhaust header system of hydraulic machine for seamless steel tube was introduced and the concrete schedule for improvement was proposed.Firstly the sealing way by inlaying seal rings between the old valve stems and guide sleeves was modified by embedding copper sleeves to the valve stems for sealing and closing off the bases of the guide sleeves. And then the water treatment facility was also improved. The operation results show that the failure rate was decreased greatly while the operation efficiency of the hydraulic machine was increased.
