我国首条双头高压水压试验机生产线的研制

The Research & Development of the First Domestic Manufacture Line of Dual-head High Pressure Hydraulic Testing Machine

介绍了西安重型机械研究所研制开发的国内首条双头高压水压试验机生产线的结构特点和性能参数。该水压试验机中增压器与充水头设计成一体,排气头采用了机械丝杆螺母传动形式,试压钢管的密封采用了具有国际先进水平的轴向预压紧大间隙组合密封圈,还采用了具有先进水平的小流量泄露监测报警装置。该生产线已顺利投产。

Described are the structure features and the performance parameters of the first domestic manufacture line of the dual-head high pressure hydraulic testing machine, developed by Xi＇ an Heavy Machinery Research Institute. The pressure intensifier and the water filling head are designedly integrated in the hydraulic testing machine, provided with the mechanical feed screw nut as the driven mode for the air exhaust head, with the international advanced axial pre-tightening and assembling sealing ring having large clearance as its sealing, and also with the advanced small flow leakage monitoring alarm device in the machine. The manufacture line has been successfully put into operation.
