Abstract
The utility model discloses a high-vacuum atomized jetting pump, which belongs to the class of jetting pumps. The utility model mainly comprises a jetting device, and a gas-liquid exchanging chamber, wherein, the upper part of the jetting device is provided with a sealing water pressing chamber, and the lower part is provided with an air suction chamber; the upper part of the water pressing chamber is provided with water inlets, and the bottom part is provided with water jetting nozzles; the water jetting nozzles are extended into the air suction chamber; one side of the air suction chamber is provided with air suction openings; the bottom part of the air suction chamber is connected with the gas-liquid exchanging chamber through throats; the bottom part of the gas-liquid exchanging chamber is connected with tail tubes. Because the organic combination of the jetting pump and the gas-liquid exchanging chamber are adopted by the utility model, the defects of the prior art, such as lower vacuum degree, only suitable for coarse vacuum occasions, and small using ranges are completely solved.
Description
The utility model belongs to the jet pump class, specifically is a kind of high vacuum mist jet pump.
Existing water-jet technology is used commonplace in the vacuum field, but its structural type is subjected to water conservancy project to make medium, the restriction of pressure gasfication condition, and degree of vacuum is lower, is only applicable to the coarse vacuum occasion, makes this The Application of Technology scope be subjected to great limitation.
It is a kind of simple and compact for structure that the purpose of this utility model is to provide, degree of vacuum height, the high vacuum mist jet pump of applied range.
The utility model is achieved through the following technical solutions:
A kind of high vacuum mist jet pump, mainly comprise sparger and vapour-liquid switch room, the top of sparger is provided with the pumping chamber of sealing, the bottom is an induction chamber, offers water intake on the pumping chamber, and water spout is installed in the bottom, water spout is visited and is stretched in induction chamber, one side of induction chamber has intakeport, and the induction chamber bottom connects the vapour-liquid switch room by trunnion, and vapour-liquid switch room bottom connects tail pipe.
Above-mentioned vapour-liquid switch room and trunnion connection place are the Taper Pipes of flaring, with the tail pipe connection place be the Taper Pipe that gradually closing is contracted, and flaring Taper Pipe entrance point diameter is greater than reducing Taper Pipe outlet end diameter, the water outlet end flare of the water spout of pumping chamber bottom, to adapt to the trunnion connection place is the Taper Pipe of flaring, the tail pipe upper part diameter is less than the diameter of bottom, and the pipe shaft between the upper and lower opening end is slick and sly conical tube structure.
The utility model has compared with prior art adopted jet pump and vapour-liquid switch room to organically combine, and has installed corresponding match equipment additional, and it is lower thoroughly to have solved prior art degree of vacuum, is only applicable to the coarse vacuum occasion, the defective that application area is narrow.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model example structure schematic representation.
Fig. 2: the utility model embodiment user mode reference drawing.
As shown in Figure 1, this high vacuum mist jet pump, it mainly comprises sparger 13, trunnion 3 that sparger 13 is installed successively and tail pipe 1.
Described sparger comprises pumping chamber 6 and inhales steam chest 4, pumping chamber 6 and suction steam chest 4 relative closures, on pumping chamber 6, have water intake, this water intake can connect with the water source by pipeline 8 and water pump 10, and pumping chamber 6 one ends are installed water spout 5, and water spout 5 is visited and stretched in inhaling steam chest 4, one side of inhaling steam chest 4 has inhales steam ports 7, the water outlet end flare of water spout 5 to adapt to bigger throat diameter, also can be other structural type.
Described trunnion and tail pipe connection place are the cylindrical body of hollow, and entrance point is that Taper Pipe, the outlet end of flaring is the Taper Pipe that gradually closing is contracted, and the entrance point diameter is greater than the outlet end diameter, and this cylindrical body constitutes a vapour-liquid switch room 2; The tail pipe upper part diameter is less than the diameter of bottom, and the pipe shaft between the upper and lower opening end is slick and sly conical tube structure.
In use, tail pipe 1 is combined as a whole with the separator box that connects vacuum equipment, the water intake of pumping chamber 6 connects with the water source by pipeline 8 and water pump 10, start water pump 10 and vacuum equipment, then under the suction function that vacuum equipment produces, negative pressure vapor-liquid separator 11 and the tail pipe 1 that links with it, vapour-liquid switch room 2, form negative pressure in trunnion 3 and the suction steam chest 4, work along with water pump 10, water enters pumping chamber 6, and enter by water spout 5 and to inhale steam chest 4, very high because of inhaling in the steam chest 4 degree of vacuum, the water-jet a fluid stream that gets off from water spout 5 partly becomes steam and emits heat, temperature reduces, and wherein steam to enter trunnion 3 near velocity of sound, thereby jet beam is actually the vapour-liquid mixture, in inhaling steam chest 4, vapour-liquid is bigger than more, the degree of vacuum that forms is just high more, raising along with degree of vacuum, the temperature of water reduces, reach a kind of vapour-liquid ratio, degree of vacuum, the dynamic equilibrium state that temperature is coordinated mutually, the working mechanism that its degree of vacuum that Here it is improves, when the vapour-liquid mixtures that form in the suction steam chest 4 enter the top of vapour-liquid switch room 2 by trunnion, because of vapour-liquid switch room inner chamber becomes big from top to bottom gradually, so vapour-liquid is spread, along with advancing of vapour-liquid, enter the bottom that vapour-liquid switch room 2 inner chambers diminish gradually, according to fluid characteristics, at the big specific volume of contraction section, the steam that supersonic speed flows is along with pressure raises, the liquid state that gradates to little specific volume enters tail pipe 1, this moment, most of steam became liquid phase, its flow velocity reduces rapidly, pass through the further diffusion of tail pipe again, enter vapor-liquid separator 11 by tail pipe 1, because vapor-liquid separator is negative pressure state at work, thereby the back pressure that spues of tail pipe 1 is very low, created the condition an of necessity for the higher degree of vacuum of suction steam chest 4 generations on its top, through cooled current admission liquid/gas separator 11, in vapor-liquid separator 11, carry out vapor-liquid separation, and with hydropexis in the casing of vapor-liquid separator 11.
