摘要
针对耐高温压力脉冲试验中实际最小压力值无法达到0表压的问题,在深入研究液体压力脉冲形成和控制原理的基础上,采用工控机和PCI板卡控制,以VB为编程环境,研究设计了一种新型的高性能压力脉冲试验台。经试验证明,本试验台在实际使用工况下卸载压力值可达到0,这不仅提高了耐高温压力脉冲实验的可靠性,同时也进一步保证了产品的测试效果及合格度。
A new high-performance pressure pulse tester is proposed for the problems of that the value at actual minimum pressure cannot reach zero gauge pressure in high temperature resistant pressure pulse tester.Based on deep research of the forming and controlling principle for the liquid pressure pulse,The industrial personal computer and PCI interface card control are used with VB programming environment for designing such a new tester.It is proved that the tester can reach zero discharging pressure value in actual working conditions.Not only it increases the high temperature resistant pressure pulse test reliability,also further guarantees the product＇s test effectiveness and qualified degrees.
