Abstract
The utility model relates to an antifreezing self-circulation environment-friendly liquid ring vacuum pump without continuous liquid refilling, which comprises a pump body and an impeller. An air section port is disposed at the top of the pump body, a liquid storage tank is in airtight connection above the pump body, an air outlet is disposed at the top of the liquid storage tank, a liquid return pipe is disposed under the liquid storage tank, and the liquid return pipe is in airtight connection with a pump cavity liquid refilling port. The pump can produce higher vacuum degree, is large in suction flow quantity, can feed adaptive vacuum liquid according to working conditions and conveying media of the device, has the advantages of self circulation of the vacuum liquid without continuous liquid refilling, enlarges application scope, can be operated in an outdoor condition with low temperature and without water sources, and is worthy of environment-friendly equipment as the pump adopts a vacuum liquid self-circulation non-leakage structure form.
Description
Technical field
The utility model relates to a kind of liquid-ring vacuum pump, particularly a kind of continuous fluid infusion, antifreeze self-circulation environmental-friendly liquid-ring vacuum pump of need not.
Background technique
Water ring vaccum pump is to be used for one of capital equipment of intake-gas manufacturing vacuum condition, is widely used in industry departments such as oil, chemical industry, electric power, electronics, metallurgy, environmental protection and food, pharmacy, synthetic fiber.
Water ring vaccum pump is gas to be wrapped up in from the water ring vaccum pump suction port by impeller rotation driving water to deliver to the air outlet discharge.Because in the course of the work, work done produces heat, can make the heating of building ring flowing water, and a part of water and gas are drained together simultaneously, so water ring vaccum pump at work, and necessary constantly supplementing water is to satisfy the job requirement of pump.
The shortcoming that water ring vaccum pump exists: 1, because of water ring vaccum pump at work, continuous supplementing water, so, its waste water resource.2, winter can't be in outdoor application.3, can't move use.
The model utility content
The utility model is at above-mentioned problems of the prior art, provide a kind of self-loopa that can inject with it the vacuum liquid that is suitable for mutually according to different working conditions need not continuous fluid infusion, need not antifreeze, can fixedly mount, the also self-circulation environmental-friendly liquid-ring vacuum pump of removable use, solved waste resource, winter in the prior art can't be in outdoor application, and can't move the problem of use.
The technical solution of the utility model is as follows:
Comprise the pump housing and impeller, the pump housing is provided with intakeport, and the top of the pump housing is provided with flange; The top of the pump housing liquid tank that is tightly connected, the top of liquid tank is provided with the air outlet, and the liquid tank bottom is provided with liquid return pipe, liquid return pipe and close connection of pump chamber fluid infusion implication.
Be provided with gas-liquid separator in the described liquid tank.
Working principle of the present utility model is:
1, in liquid tank, injects quantitative vacuum liquid; Vacuum liquid is selected according to the environmental conditions that the characteristic of the medium that vacuum pump contacted and equipment use, that is: vacuum liquid with should not produce chemical reaction after medium contacts, winter, vacuum liquid should not solidify when outdoor application.
2, vacuum liquid enters pump chamber by liquid return pipe, and the impeller rotation drives the vacuum liquid movement in the pump chamber, and vacuum liquid is wrapped up in gas from intakeport and delivered to liquid tank, and after liquid tank carried out gas-liquid separation, gas was discharged from air outlet, liquid tank top.
3, the vacuum liquid after the gas-liquid separation is in liquid return pipe returns pump chamber.
The utility model has the advantages of as follows:
The utility model can be made higher degree of vacuum, and inhalation flow is big, can dose the vacuum liquid that adapts according to the working environment (as winter) and different fed sheet of a media of device.And has a self-loopa of vacuum liquid, do not need the characteristics of continuous fluid infusion, enlarged the Applicable scope of vacuum pump, be suitable for the outdoor operation that low temperature does not in the winter time have the water source again, because this pump has adopted the leak free structural type of vacuum liquid self-loopa, make it become a kind of genuine environmental protection equipment again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, the pump housing, 2, liquid tank, 3, the air outlet, 4, liquid return pipe, 5, pump chamber fluid infusion mouth, 6, intakeport.
Embodiment
Embodiment 1
