Once the portable waterjet was launched, it would "cut" a "miracle." In June 2010, a construction site in Hebei Province accidentally discovered an unexploded aerial bomb during operation.
The missile is about 150cm long and about 50cm in diameter. The projectile has been severely corroded. There is a fuse at each end and it is well preserved. The charge is more than 500kg. Such a shell, despite years of wind and rain, has not weakened its power. Once exploded, the shock wave can keep the grass within the diameter of 1000 meters!
However, if detonation is to be carried out, it is necessary to transport the bomb to an open space for deep blasting.
However, during transportation, the vibration of the vehicle and the inertia of the vehicle when turning corners are highly likely to cause the fuze to trigger an explosion. The local public security department contacted Bo Yueda and requested the use of water cutting to destroy the shells. There is no precedent in the country for cutting such a huge bomb with a water knife.
At the dismantling site, the explosion-producing expert placed the newly developed portable water-cutting device on the projectile. In a nervous mood, he started the waterjet. After an hour, the bombs were completely separated, the danger did not happen, and all the personnel were safe and sound! Before the invention of the portable waterjet, Ji Xingang did not understand that there were similar products abroad.
Foreign products are not only expensive, but also in a state of technical blockade. A construction unit compared the waterjet invented by Ji Xingang with the waterjet produced in Germany. Everyone found that Ji Xingang's waterjet is not as good as foreign products, but has higher cutting efficiency, lower operating power consumption, and less than half the sales price of foreign products.
"The function of the waterjet is constantly expanding, and the portable waterjet will do it."
