Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model provides a high energy injection apparatus, compared with the prior art, the utility model discloses high energy injection apparatus lets in gas earlier in to pressure vessel 2 through air compressor machine 1, when pressure detector detected pressure in pressure vessel 2 and reached first default, stops to pour into gas into in pressure vessel 2, opens high-pressure pump 3 and pours into liquid into in to pressure vessel 2, when pressure in pressure vessel 2 reached the second default, stops to pour into liquid into in to pressure vessel 2. And opening the switch valve 6, and rapidly expanding the gas under the action of the internal and external pressure difference to extrude the liquid out of the pressure vessel 2 to form high-pressure injection. The device can realize high-energy remote injection, achieves the effects of long injection stroke and large injection flow, has low energy consumption and reduces the injection cost.
When the air compressor 1 injects air into the pressure vessel 2, the air compressor 1 can rapidly inject air into the pressure vessel 2 without consuming excessive energy because the pressure vessel 2 is initially in a normal pressure state.

As can be seen from the k-lamblon equation,
PV＝nRT
the deformation yields the formula:
PV＝P 0 V 0
wherein P represents the pressure in the pressure container before liquid injection, and V represents the gas volume in the pressure container before liquid injection; p is 0 Indicating the pressure, V, in the pressure vessel after filling 0 Indicating the volume of gas in the pressure vessel after filling.
It can be seen that when the liquid is injected into the pressure vessel 2, the volume of the gas is compressed and the pressure of the gas increases, and the volume of the gas is inversely proportional to the pressure. For example, when the volume of gas is compressed to 1/2 of the original volume, i.e., when 1/2 of the liquid is injected into the pressure vessel, the pressure in the pressure vessel increases by 2 times. When the gas volume is compressed to 1/4 of the original volume, namely 3/4 of the liquid is injected into the pressure container, the pressure in the pressure container is increased by 4 times.
