- the compressor 30 is driven in a state in which the third valve 53 is closed and the second valve 52 is open.
- the high-pressure second fluid F2 moves along the second supply line L2 and is sprayed into the nozzle assembly 100 .
- the first fluid F1 stored in the storage tank 10 is self-priming.
- the second fluid F2 is injected at a high pressure, the pressure at the outlet of the nozzle assembly 100 is lowered, so that the first fluid F1 flows from the reservoir 10 along the first supply line L1 to the nozzle assembly ( 100) to go to That is, the injection system 6 may inject the first fluid F1 without additional driving for moving the first fluid F1 .
- the second valve 52 is closed or opened, and the compressor 30 is driven when the third valve 53 is opened.
- the high-pressure second fluid F2 moves along the second 'supply line L2' and moves to the rear end of the first supply line L1.
- the check valve CV may be disposed between the first supply line L1 and the second supply line L2' to set the flow direction of the second fluid F2.
- the second fluid F2 moving to the first supply line L1 may clean the nozzle assembly 100 and clean the first filter 41 .
- the first fluid F1 remaining in the first supply line L1 may be recovered to the storage tank.
- a check valve CV in the injection system 6 can optionally be provided. For example, if the first supply line (L1) or the second supply line (L2) is long, the check valve (CV) is installed, if short, the check valve (CV) may be omitted.
- the injection system 6 may optionally include a flow rate measuring unit 11 for measuring a flow rate of the first fluid F1 stored in the reservoir 10 .
- the flow rate measuring unit 11 may include a water level control ball to measure the flow rate of the first fluid F1 stored in the storage tank 10 .
- the first fluid F1 may be additionally supplied to maintain a constant water level.
- the flow metering unit 11 may also be applied to the aforementioned injection control systems 1 , 2 , 3 , 4 , 5 .
- the injection system 6 can optionally be equipped with a pump 20 .
- a pump 20 may be additionally installed.
- the pump 20 may optionally be provided also in the injection systems 1, 2, 3, 4, 5 described above. Even in the injection systems 1, 2, 3, 4, and 5 described above, the second fluid F2 may be injected to the compressor 30, and the first fluid F1 may be self-priming.
- the nozzle assembly and the injection system according to the present invention can atomize the injected fluid to a very small size.
- Different fluids are introduced into the nozzle assembly, and when the first fluid is sprayed, the second fluid having a turning force collides with the first fluid to pulverize the first fluid.
- the second fluid having a turning force guides the movement of the first fluid, so that the first fluid may be sprayed over a large area.
- the nozzle assembly and the injection system according to the present invention can remove foreign substances inside.
- the end of the nozzle assembly is blocked, the flow direction of the second fluid is changed, and the flow direction of the first fluid is reversed.
- the second fluid may remove foreign matter inside the nozzle assembly and the injection system from the filter or strainer.
- the nozzle assembly and the injection system according to the present invention may change the flow of the second fluid to clean the inside.
- the interior of the injection system may be cleaned.
- the nozzle assembly and the spraying system including the same may be applied to various industrially available devices capable of spraying a fluid.
