现在的等离子弧切割机大多靠气体压力来控制流量，因为当枪体孔径一定时，控制了气体压力也就控制了流量。
Now the plasma arc cutting machine part on gas pressure to control the flow, because when gun aperture, the gas control certain pressure and you control the flow.
在相同结构和装药量的条件下，复合射孔在井下作业能够产生较高的枪内压力，容易引起接头的剪切脱落失效。
Under the conditions of similar structure charging rate, higher pressure in the perforators can be produced in downhole operation by using combined perforation, failure would be caused in its joints.
介绍一种复合射孔器模拟试验装置和动态压力测试方法，可对复合射孔器射孔单元组成模拟枪体，在相配套的模拟试验装置内进行试验。
Introduced are a simulating device of fracture perforators and a dynamic pressure testing method. Some simulation body composed of combined perforator units can be tested in the simulation device.
枪嘴压力坚持在40—50镑时最为抱负，太大或太小的压力会影响喷涂作用及形成浪费。
Muzzle pressure is the most ambitious in 40-50 pounds, too large or too small pressure will affect the role of spraying and the formation of waste.
总之，根据两杆枪压力表读数的情况，可以判断出管束是否泄漏和堵塞。
In short, according to the two gun pressure gauge readings, you can determine whether the leakage and blockage of the tube.
若有特殊要求试验压力超过0.5MPa时，可制做配套夹具固定在换热器管板上，推压枪头进行试验。
If you have special requirements, test pressure exceeds 0.5mpa, the matching manufacture fixture is fixed on the heat exchanger tube plate, pushing pressing head test.
