Abstract
The utility model discloses a water-ring vacuum pump comprising a pump body and an impeller, wherein the impeller is arranged at the inner part of the pump body eccentrically; and the upper part of the pump body is provided with an air suction port and an air exhaust port. When the impeller rotates, water entering the pump body is thrown toward the periphery by the impeller, and due to the function of centrifugal force, the water forms an equal-thickness closed water ring similar to the shape of a pump cavity. The inner surface of the upper part of the water ring is rightly tangential to a hub of the impeller, and the inner surface of the lower part of the water ring is rightly contacted with the top ends of blades, at the moment, a crescent space is formed between the hub of the impeller and the water ring, while the space is divided into a plurality of small cavities with the equal number of the blades again. The water-ring vacuum pump has the advantages of large amount of air exhaust, high efficiency, water and power conservation and the like.
Description
Technical field
The utility model is a kind of vacuum pump, especially a kind of water ring vaccum pump.
Background technique
At present, the vacuum pump that uses on the market makes the quantity of impeller very intensive in order to reach water displacement, has so just reduced the air displacement of water pump, causes water pump to do a lot of idle works.Simultaneously the level of impeller is installed and is caused impeller to slip into when work making pump load strengthen in the water too deeply, reduced the efficient of water pump, wasted a large amount of power and waters, wasted a large amount of energy.
The model utility content
The utility model is to have solved that above-mentioned technical problem provides that an air displacement is big, efficient is high, a kind of water ring vaccum pump of water saving power saving.
For this practical water ring vaccum pump of defective that overcomes above-mentioned prior art comprises: the pump housing, impeller, described impeller off-centre be installed in described pump housing inside, described pump housing top is provided with intakeport, relief opening.When impeller rotated, around the water that enters the pump housing was thrown to by impeller, because action of centrifugal force, water had formed the water ring of the sealing of an equal thickness similar to the pump chamber shape.The upper inside surface of water ring is lucky and impeller hub is tangent, and the lower inner surface of water ring just contacts (in fact, blade has certain insertion depth in water ring) with blade tip.At this moment, formed a month teeth cavity between impeller hub and the water ring, teeth cavity was divided into several loculuses that lobe numbers equates by impeller again in described month.If the top zero degree with impeller is a starting point, impeller is when rotation last 180 is spent so, the volume of loculus changes from small to big gradually, pressure constantly reduces, and communicate with the intakeport on the suction and discharge dish, the pressure in little cavity space is lower than the pressure of being taken out in the container, according to the gas pressure intensity principle for balance, the gas of being taken out constantly is drawn into loculus, is in breathing process this moment.When air-breathing finishing and intakeport isolated, the volume of loculus reduces just gradually, pressure constantly increases, and is in compression process this moment, when the gas of compression reaches exhaust pressure in advance, shifts to an earlier date exhaust from auxiliary exhaust valve.And reducing pressure further, the volume of the loculus that communicates with relief opening further raises, when the pressure of gas during greater than drain pressure, compressed gas is discharged from from relief opening, in the continuous operation process of pump, is constantly carrying out the process of air-breathing, compression, exhaust.Thereby reach the purpose of continuous air extraction.
The utlity model has following beneficial effect in sum:
1, air displacement is big;
2, efficient height;
3, water saving power saving.
Description of drawings
Fig. 1 is the structural representation of a kind of water ring vaccum pump of the utility model;
Wherein: the 1-pump housing, 2-impeller blade, 3-intakeport, 4-relief opening, 5-month teeth cavity, 6-water ring, 7-loculus.
Embodiment
Separating a kind of water ring vaccum pump as Fig. 1, the utility model comprises: the pump housing 1, impeller 2, described impeller 2 off-centre be installed in the described pump housing 1 inside, described pump housing top is provided with intakeport 3, relief opening 4.When impeller rotated, around the water that enters the pump housing 1 was thrown to by impeller 2, because action of centrifugal force, water had formed the water ring 6 of the sealing of an equal thickness similar to the pump chamber shape.The upper inside surface of water ring 6 is lucky and impeller 2 wheel hubs are tangent, and the lower inner surface of water ring 6 just contacts (in fact, blade has certain insertion depth in water ring) with blade tip.At this moment, formed a month teeth cavity 5 between impeller 2 wheel hubs and the water ring, teeth cavity was divided into several loculuses 7 that lobe numbers equates by impeller 2 again in described month.If the top zero degree with impeller 2 is a starting point, impeller 2 is when rotation last 180 is spent so, the volume of loculus 7 changes from small to big gradually, pressure constantly reduces, and communicate with the intakeport 3 on the suction and discharge dish, the pressure in loculus 7 spaces is lower than the pressure of being taken out in the container, according to the gas pressure intensity principle for balance, the gas of being taken out constantly is drawn into loculus 7, is in breathing process this moment.When air-breathing finishing and intakeport 3 isolated, the volume of loculus 7 reduces just gradually, pressure constantly increases, and is in compression process this moment, when the gas of compression reaches exhaust pressure in advance, shifts to an earlier date exhaust from auxiliary exhaust valve.And reducing pressure further, the volume of the loculus 7 that communicates with relief opening 4 further raises, when the pressure of gas during greater than drain pressure, compressed gas is discharged from from relief opening 4, in the continuous operation process of pump, is constantly carrying out the process of air-breathing, compression, exhaust.Thereby reach the purpose of continuous air extraction.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (3)
1. the utility model discloses a kind of water ring vaccum pump comprises: the pump housing, impeller, described pump housing top is provided with intakeport, relief opening, it is characterized in that: described impeller off-centre be installed in described pump housing inside.
2. a kind of water ring vaccum pump as claimed in claim 1 is characterized in that: formed a month teeth cavity between described impeller hub and the water ring.
