摘要
GB25974.3-2010规定液压支架用阀小流量特性试验的系统流量为0.04 L/min,国内阀生产类企业不具备试验条件,针对这一现象,研制了一套微小流量能够自动调节的试验装置,利用先进电液比例控制技术,试验装置中的流量能够利用电气信号连续地、按比例地进行控制,完全满足国标试验要求,极大提高矿用支护类产品的检测技术水平。
The system flow valve with small flow characteristic test of hydraulic supportis 0.04 L/min in the GB25974.3-2010, the domestic valve production enterprises have no test conditions, in view of this phenomenon, we developed a set of small flow can test device of automatic adjustment, the use of advanced control technology of electro hydraulic proportional, in the test device can use continuous electrical signal flow land, according to the proportion of the control flow, fully meet the national standard testing requirements, greatly improve the level of detection technology of mine support products.
