Example 1
Referring to fig. 1-4, a primary vertical liquid injection vacuum-pumping device comprises an injector 1, a gas cylinder 2, a liquid outlet pipe 3, an injection pump 4 and a flow damper 5; the ejector 1 is arranged at the upper end of the gas collecting cylinder 2, and the lower part of the gas collecting cylinder 2 stores liquid 11; the ejector 1 comprises an ejector outlet pipeline 6, an ejector liquid inlet 7 and an ejector gas inlet 8, the ejector outlet pipeline 6 extends downwards to the lower side of the liquid level in the gas collecting cylinder 2, the ejector liquid inlet 7 is connected with the ejector pump 4, the ejector pump 4 is connected with a liquid storage position in the equipment 12 needing vacuumizing, and the ejector gas inlet 8 is connected with a gas storage position in the equipment needing vacuumizing; the flow damper 5 is arranged inside the gas collecting cylinder 2, and the lower end of the ejector outlet pipeline 6 is inserted into the flow damper 5; an exhaust pipe 9 is arranged on the upper part of the side wall of the gas collecting cylinder 2, one end of the liquid outlet pipe 3 is connected with the bottom of the gas collecting cylinder 2, and the other end is connected with a liquid storage position in equipment needing vacuumizing.
The exhaust pipe 9 is arranged at the upper part of the gas collecting cylinder 2, so that the gas in the gas collecting cylinder 2 can be conveniently discharged. Ejector outlet pipe 6 downwardly extending to gas collecting cylinder 2 in the liquid level downside, seal through liquid to the air and water that draw and jet out, simultaneously, the distance is suitable between the upper end opening of drain pipe 3 and flow straightener 5, is favorable to air and water that ejector 1 penetrated to carry out abundant separation, prevents that the air from getting into the equipment that needs the evacuation again along with water.
Further, the flow damper 5 is a container with an open upper end, and the lower end of the flow damper 5 is connected with the bottom end of the gas collecting cylinder 2.
Further, the flow damper 5 is formed by connecting two cylindrical structures, the diameter of the upper cylindrical structure is larger than that of the lower cylindrical structure, and the lower end of the ejector outlet pipeline 6 is arranged in the upper cylindrical structure.
After the mixture of water and air injected from the injector outlet pipeline 6 of the injector 1 enters the flow damper 5, the liquid in the gas collecting cylinder 2 seals the injected water and air because the injector outlet pipeline 6 extends downwards to the lower side of the liquid level in the gas collecting cylinder 2; and the space that water and air that draw and penetrate locate becomes big, and pressure diminishes, leads to the velocity of flow of water to slow down, and because the opening only on the upper end of flow damper 5, flow damper 5 produces the effect of blockking to water, consequently, further slows down the velocity of flow of water, and at this moment, air and separation of water, air remove to the gas collecting cylinder 2 of liquid level upside in to guarantee that the air that draws out no longer gets into the equipment that needs the evacuation along with water. The design of the structure of the flow damper 5 ensures that the injected water and air can quickly slow down the flow speed, and the injected water and the water in the gas collecting cylinder can be quickly mixed, thereby ensuring the separation efficiency of the water and the air.
