正压风筒测定系统工艺的优化设计

Optimum Design of System Process of Positive Pressure Air Duct

正压风筒测定系统测定是通过开启配套的局部通风机的不同级电动机,通过加载、变频等方式调节井下局部通风工况,模拟井下实际运行的通风系统工况,验证主通风机稳定性,并检测风筒通风性能。一般指标为风量、风压、用电量、温湿度、噪音量等。原有的测定系统存在轨道支架固定机构加工费事、困难;风筒联接螺钉、风道涂覆布的挂链等易锈蚀;风筒法兰之间的密封材料,容易失效等问题。因此,针对以上存在的问题,优化测定系统工艺的设计,研究出一套便捷、高质量的风筒测定系统,降低了成本。

The positive pressure air duct determination system is through the local ventilator supporting the open motor, underground local ventilation condition by adjusting the loading frequency, etc., simulation of underground ventilation system in actual operation, to verify the main ventilator stability, simultaneous detection of wind tube ventilation performance. The general indexes are air volume, wind pressure, electricity consumption, temperature and humidity, noise volume and so on. There are rail bracket fixing mechanism, difficult processing trouble determination system original; air duct connecting screw, duct coating cloth lanyards and other easy to rust; sealing material duct between the flanges, easy to failure. Therefore, in view of the above problems, the design of optimization system technology is optimized and a set of convenient and high quality wind tunnel measuring system is studied to reduce the cost.
