THE EXPERIMENTAL STUDY ON GAS DETONATING SYSTEM BY NEW-TYPE OF GAS SOURCE

摘要

Liquified petroleum gas mixed with oxygen has been used as a new type of mixed gas source for gas detonating system-The experimental studies have been done on the detonation feature of gas detonating transmission in a long and thin tube, the transmitting reliability for detonating network, the design on gas exploder and test devices. The results of the study show that (1)Liquified petroleum mixed with oxygen can be used as a new type of regular gas source. (2)The transmission of detonating wave is reliable for new type of mixed gas in a 500-meter long plastic tube with 3mm inner diameter and the detonating volocity is up to 2500m/s. The detonating wave can surely initiate and transmit several branched gas detonating cap and explosive through the end of detonating network,the tubes inner diameter for the detonating quenching is 0. 7mm- (3)The gas exploder designed by authors can be used for gas propotional distribution,strong turbulence-mixing,initiating by reflex shock wave and safety control purposes. The developed double flowmeter can be used together or seperately in responsible for main testing in the system.
