Abstract
The utility model relates to a steam-jet vacuum pump. Steam is connected with a steam jet device through a pipe; the steam jet device and a condenser are connected into a liquid sealing pond through pipes; the steam jet device is connected with a suction inlet and a pressure expanding pipe of a mixing chamber through a steam jet nozzle; and the steam jet device is communicated with the condenser through a pipe; and groups of steam-jet vacuum pumps can be provided and connected in series through pipes. The steam-jet vacuum pump has simple structure, works stably, is convenient to control the vacuum height and does not need any prime motor.
Description
Technical field
The utility model relates to a kind of vacuum pump, is specifically related to a kind of steam jet vaccum.
Background technique
At present, known vacuum pump kind mainly contains reciprocating pump, sliding vane rotary vacuum pump, sliding valve vacuum pump, Roots pump and water ring vaccum pump, is by reciprocating motion of the pistons or rotation gas to be sucked, compresses and discharges.Shortcoming is along with the increase working vacuum degree that overhauls number of times will constantly descend, until not satisfying the requirement of producing.This type of pump work noise is big, and fuel consumption is big, and the rate of fault height also is its shortcoming that causes.The vacuum pump that has can only aspirate non-condensable gas or can not aspirate and have granular medium, has limited its using scope.
The model utility content
Task of the present utility model is to provide a kind of steam jet vaccum.
In order to solve above technical problem, a kind of steam jet vaccum of the present utility model, connect injection apparatus by steam by pipeline, described injection apparatus and condenser are connected in the fluid-tight pond by pipeline and constitute, it is characterized in that: described injection apparatus by nozzle connect suction port, the mixing chamber diffuser pipe constitutes, described steam jet vaccum is made of by pipeline and condenser UNICOM injection apparatus.
Described steam jet vaccum can be divided into some groups, contacts by pipeline between group and the group.
Described group with group between polyphone be: be connected on the outlet of diffuser pipe and the condenser shell side.
The advantage of above structure is: vacuum pump simple in structure, and working stability is convenient to operate the degree of vacuum height, and without any need for prime mover.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a partial enlarged drawing of the present utility model shown in Figure 1.
Embodiment
As shown in Figure 2, injection apparatus of the present utility model is made of steam nozzle 1, intakeport 2, mixing chamber 3, diffuser pipe 4, described condenser 5,6,7 is divided into tube side and shell side, tube side inserts by pipeline and is full of condensed water, and working steam and condensable gas cool off after liquid sealing pipe enters fluid-tight pond 8 in the condenser shell side.
Described steam jet vaccum can be divided into some groups, and as shown in Figure 1, this example is divided into four groups of A, B, C, D, group with organize between be connected by pipeline 10.For the better controlled steam flow, distribution of steam cylinder 9 is housed on steam pipework, steam is divided into some branch roads, be connected respectively on the nozzle of each group.
During work, working steam enters by nozzle 1, and ejection at a high speed produces low pressure, and gas is mixed from intakeport 2 suctions and at mixing chamber 3, and behind diffuser pipe 4, kinetic energy is converted into the pressure energy.Mixed gas enters condenser subsequently, and by liquid sealing pipe row feed liquor envelope pond, non-condensable gas is inhaled into the next stage vapor pump, so repeatedly circulation after working steam and the condensable gas condensation.In the utility model patent application, vapor pump and condensation device constitute a combination, and each combination is divided into one-level, and four are combined as level Four, the shared condenser of the one or two two-stage jet pump.
Claims (3)
1, a kind of steam jet vaccum, be connected injection apparatus with steam by pipeline by vacuum, described injection apparatus and condenser are connected in the fluid-tight pond by pipeline and constitute, it is characterized in that: described injection apparatus constitutes by connecting diffuser pipe on the nozzle, and described steam jet vaccum is communicated with condenser by pipeline by injection apparatus, diffuser pipe and constitutes.
2, a kind of steam jet vaccum according to claim 1, it is characterized in that: described steam jet vaccum can be some groups, contacts by pipeline between group and the group.
3, a kind of steam jet vaccum according to claim 2 is characterized in that: described group with the group between the polyphone be: the upper end of condenser is connected with the upper end of diffuser pipe.
