内混式介质雾化喷嘴运行时,当运行油压高于某雾化气体压力时,会发生部分油经气孔倒流入气管系统的第一类临界工况;当运行雾化气体高于某油压时,会发生部分雾化气体经油孔倒流入油管系统的第二类临界工况。对某内混式喷嘴采用冷态流量实验研究与数据处理相结合的方法,确定了这两类临界工况,为内混式喷嘴的可靠运行提供了依据。 Internal mixed media atomization nozzle operation, when the operating pressure is higher than a certain atomizing gas pressure, some of the oil will occur through the stoma back into the first critical condition of the trachea system; when the operation of atomizing gas above a certain oil When pressure is applied, a second type of critical condition may occur where part of the atomized gas flows back into the tubing system through the oil hole. The method of combining cold flow experimental research and data processing for an internal mixed nozzle was used to determine these two critical conditions and provide the basis for the reliable operation of the internal mixed nozzle.
