Abstract
A water-ring vacuum pump comprises an impeller, a hub, a pump body, gas suction openings, exhaust openings and supports, wherein the pump body is fixedly mounted on the supports; one gas suction opening and one exhaust opening are formed in the upper part of the pump body; the other gas suction opening and the other exhaust opening are formed in the left side and the right side of the pump body respectively; the hub is mounted in the pump body; the impeller is eccentrically mounted on the hub in the pump body. The water-ring vacuum pump is simple in structure and easy to machine and has a low requirement on manufacturing accuracy. The water-ring vacuum pump has a compact structure and a high revolving speed, generally can be in direct connection with a motor and does needs a reduction gear, therefore, the water-ring vacuum pump can achieve high gas displacement with a small structure size and meanwhile occupies a small area. Compressed gas is basically isothermal, that is, temperature changes very little in a gas compression process. As no metal wearing surface is arranged in a pump chamber, the interior of the water-ring vacuum pump doesn't need to be lubricated, and the abrasion is very small. Sealing between a rotating part and a fixing part can be water sealing. The water-ring vacuum pump sucks gas uniformly, works stably and reliably, and is simple to operate and convenient to maintain.
Description
Technical field
The utility model relates to a kind of vacuum pump, especially a kind of Nash hytor.
Background technique
Nash hytor is called for short water ring pump, in the many manufacturing processs in the industries such as oil, chemical industry, chemical fibre, machinery, mine, power, metallurgy, light textile, papermaking, medicine and food, is widely applied.For example, vacuum filtration, vacuum evaporation, vacuum feeding, vacuum outgas, vacuum conditioning and Vacuum Concentration etc.Because the process of water ring pump pressurized gas is isothermal, therefore can also extract inflammable and explosive gas out.In addition, water ring pump also can be extracted the moisture gas of dust-laden out.The cavity volume of most of vacuum pumps is fixed at the volume in when work in the market, and therefore when water ring pump is worked, well air-breathing, exhaust, has reduced the working efficiency of vacuum pump.
Summary of the invention
The technical problems to be solved in the utility model is: for overcoming the shortcoming and defect of existing Nash hytor, provide a kind of simple in structure, variable-capacity vacuum pump.
The technological scheme that the utility model solves the problems of the technologies described above is: a kind of Nash hytor, comprise impeller, wheel hub, the pump housing, intakeport, relief opening, support, the pump housing is fixedly mounted on support, pump housing top is provided with an intakeport and a relief opening, the pump housing left and right sides is respectively equipped with an intakeport or relief opening, wheel hub is installed in the pump housing, and impeller is arranged on the wheel hub in the pump housing by bias.
Technique effect of the present utility model is: Nash hytor is simple in structure, and accuracy of manufacturing is less demanding, easily processing.Nash hytor compact structure, the revolution of pump is higher, generally can with motor direct connection, need not speed reducer, therefore by little physical dimension, can obtain large air displacement, floor space is also little.Pressurized gas is isothermal substantially, and pressurized gas process temperature changes very little.Owing to there is no metal friction surface in pump chamber, need not be to being lubricated in pump, and also wearing and tearing are very little.Sealing between rotating component and fixed block can directly be completed by water seal.Air-breathing even, stable working is reliable, simple to operate, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, impeller, 3, the pump housing, 4, intakeport, 5, relief opening, 6, support.
Embodiment
The utility model describes in detail by drawings and Examples:
As shown in Figure 1, a kind of Nash hytor of the utility model, comprise impeller 1, wheel hub, the pump housing 3, intakeport 4, relief opening 5, support 6, the pump housing 3 is fixedly mounted on support 6, the pump housing 3 tops are provided with an intakeport 4 and a relief opening 5, the pump housing 3 left and right sides are respectively equipped with an intakeport 4 or relief opening 5, in the pump housing 3, wheel hub are installed, and impeller 1 is by eccentric being arranged on the wheel hub in the pump housing 3.
Appropriate water is housed in the pump housing 3 as working solution.When impeller 1 is pressed the rotation of clockwise direction shown in Fig. 1, water is thrown to surrounding by impeller 1, and due to the effect of centrifugal force, water has formed a closed circle that is similar to equal thickness that is decided by pump chamber shape, is referred to as water ring.The lower part internal surface of water ring just and impeller hub tangent, the upper inside surface of water ring just contacts with impeller 1 top, in fact impeller 1 has certain insertion depth in water ring, now between impeller 1 and water ring, form a crescent-shaped space, and this space is divided into several loculuses that equate with impeller 1 number by impeller 1.If take 0 ° of the bottom of impeller 1 is starting point, the volume of impeller 1 loculus when first 180 ° of rotation changes from small to big so, and communicates with the intakeport 4 on end face, and now gas is inhaled into, when air-breathing at the end loculus isolated with intakeport 4; When impeller 1 continues rotation, loculus from large to small, makes gas compressed; When loculus communicates with relief opening 5, gas is just discharged from outside pump.
In sum, that water ring pump is that the variation by pump chamber realizes is air-breathing, compression and exhaust, so it belongs to variable-capacity vacuum pump.
The utility model is that the embodiment who mentions is with reference to the accompanying drawings illustrated, and this is part embodiment wherein, and those skilled in the art can obtain and inspire from the present embodiment, are out of shape and obtain other embodiment.Therefore, protection domain of the present utility model should be determined according to the protection domain of claim.
