Rotary Vane Vacuum Pump for Sealed Container
Sealed containers are widely used in all aspects of life. They are often used to seal things such as wine, perfume, kitchen flavors, etc.
The existing container not only needs to meet people's needs for containing liquids or solids, but also needs to have a sealing function at the same time, so as to facilitate transportation, portability and meet fresh-keeping requirements.
In today's sealed containers for wine, cork stoppers are usually used for wine, and traditional wines usually use screw caps, serrated bottle caps, cork stoppers, and silicone stoppers. Apply sealing materials such as sealing mud to the joints of the mouth to further ensure the sealing.
However, in the actual use process, it is found that sealing materials such as sealing mud directly contact the external environment. If the air environment is humid or accidentally spilled with water, or improperly touched by the user, the sealing material such as sealing mud is prone to damage, deformation and damage. Dissolution not only loses the original sealing function, but also contaminates the mouth of the bottle, which is not easy to clean completely. When the user opens the cork, it is likely to contaminate the wine in the sealed container.
Rotary vane vacuum pump is one of the most basic vacuum obtaining equipment in vacuum technology. Rotary vane vacuum pumps are mostly small and medium-sized vacuum pumps. There are two types of rotary vane vacuum pumps: single-stage pumps and double-stage pumps.
The so-called double-stage is to connect two single-stage pumps in series in structure. Generally, it is made into double-stage to obtain higher vacuum degree. The rotary vane vacuum pump can pump out the dry gas in the sealed container, and if it is equipped with a gas ballast valve, it can also pump out a certain amount of condensable gas.
The rotary vane vacuum pump solves the problems that food plastic bags cannot be sterilized, cannot be reused, and cannot be insulated, better ensure food hygiene and safety, and greatly reduce environmental pollution and resource waste.
In addition, the device also has the advantages of simple structure and easy manufacture, which improves the overall user experience, and solves the problem that the sealing material such as sealing mud set in the existing sealing container directly contacts the external environment and is easily damaged, deformed and dissolved.
