Shanghai Yetuo's domestically produced oil rotary vane vacuum pump is a basic and universal equipment for obtaining low to medium vacuum environments. It relies on pump oil sealing, lubrication, and cooling to continuously extract air and water vapor from sealed containers, creating a stable negative pressure environment. It is an indispensable supporting equipment for industries such as laboratories, pharmaceuticals, electronics, chemicals, and food, and plays a core role with different emphases in different scenarios.
1、 Laboratory research field: Constructing negative pressure conditions required for experiments
1. Vacuum pumping for freeze-drying equipment
Used in conjunction with a vacuum freeze dryer, it continuously extracts air from the warehouse to create a high vacuum environment, allowing ice crystals inside the material to sublimate at low temperatures, preserving the biological activity and original form of the sample. It is used for freeze-drying of bacterial strains, medicinal herbs, biological specimens, and reagents, and is also a standard pre vacuum pump for small laboratory freeze-drying units.
2. Vacuum drying and constant temperature dehumidification
Equipped with a vacuum drying oven to reduce chamber pressure, lower water vaporization temperature, achieve low-temperature drying, avoid high-temperature damage to thermosensitive samples, suitable for drying glassware, chemical samples, and powder materials.
3. Negative pressure operation for chemical pretreatment
Supporting experiments such as vacuum distillation, vacuum filtration, solid-phase extraction, and concentration and purification, relying on negative pressure to accelerate solvent separation speed and shorten experimental time; Simultaneously reducing the boiling point of the liquid and preventing the decomposition of active ingredients due to high temperatures, it is widely used in universities and third-party testing laboratories.
4. Small analytical instruments assist with gas supply
As a front-end pump for gas chromatography, small coating equipment, and metal sample spraying equipment, it quickly extracts impurities from the chamber to avoid interference with detection data and sample observation results caused by air impurities.
2、 Pharmaceutical and Biological Industries: Ensuring the Quality of Drug Production and Preparation Storage
1. Vacuum supply for pharmaceutical freeze-drying production line
The freeze-drying process of active pharmaceutical ingredients, probiotics, injectable powders, and vaccines is continuously evacuated and dehydrated under low-temperature vacuum to ensure drug activity. The finished products can be stored for a long time without the need for cold chain. Small and medium-sized pharmaceutical companies generally use domestically produced rotary vane pumps to reduce equipment investment costs.
2. Drug defoaming, extraction and purification
During the process of drug extraction and soft capsule production, extract container air to eliminate internal bubbles in the drug solution and improve the appearance and purity of the drug; Vacuum negative pressure accelerates the analysis of herbal effects and improves the utilization rate of raw materials.
3、 Food and agricultural product processing: extend storage period, lock in food quality
1. Vacuum packaging and air extraction
Before vacuum sealing snacks, meat products, and miscellaneous grains, extract air from the packaging bag to isolate oxygen, inhibit oxidation and mold growth, and extend the shelf life of the food.
2. Low temperature dehydration processing of agricultural and sideline products
Freeze dried processing of fruits, vegetables, mushrooms, and meat provides a vacuum environment to preserve the original flavor and nutrition of the ingredients, making freeze-dried snacks and outdoor fast food ingredients.
4、 Electronics and new energy manufacturing: ensuring the stability of component production
1. Drying and exhaust of electronic components
After cleaning the circuit board, capacitor, and coil, vacuum dry them to remove moisture from gaps, avoid short circuits and corrosion in the later stage, and improve the service life of the product.
2. Lithium battery and photovoltaic supporting technology
Lithium battery electrode vacuum dehydration, photovoltaic module packaging and exhaust, isolate air impurities, ensure battery cycling performance and photovoltaic product sealing.
3. Small vacuum coating
Before coating LED beads and hardware decorative parts, remove the air inside the chamber to prevent oxidation and peeling of the coating, and improve the uniformity and adhesion of the coating.
5、 Fine chemicals and general industries: optimizing production processes
1. Resin and silicone vacuum defoaming
Extract internal bubbles from pouring raw materials to avoid holes and cracks in finished products, and improve the quality of castings and mold products.
2. Vacuum heat treatment and mold forming
Heat treatment furnaces and injection molds should remove air in advance to reduce the oxidation and blackening of workpieces; Negative pressure assisted material filling enhances product precision.
3. Purification of oil products and chemical solvents
Negative pressure distillation separates various chemical raw materials, reduces processing temperature, and avoids the risk of high-temperature deterioration of flammable and thermosensitive chemicals.
6、 General basic auxiliary functions
1. Oil and gas separation for pollution prevention
Equipped with oil and gas separation and anti backflow structure, it blocks the backflow of oil vapor when extracting water vapor and a small amount of organic gas, reducing sample and workpiece pollution; Built in pneumatic valve can discharge water vapor and prevent pump oil from emulsification and deterioration.
2. Continuously maintain a stable vacuum
The equipment can operate continuously for a long time, compensate for the leakage of the chamber in real time, maintain a constant negative pressure throughout the process, ensure uninterrupted operation of the entire equipment, and adapt to laboratory long-term experiments and factory batch production lines.
3. Extract the mixed gas
It can simultaneously extract air, water vapor, and a small amount of low concentration organic volatile gases, suitable for most conventional working conditions without strong corrosive media, and suitable for the matching needs of the vast majority of small and medium-sized vacuum equipment.
Overall, the core function of domestically produced oil rotary vane vacuum pumps is to create stable vacuum negative pressure by extracting gas from enclosed spaces. With the help of negative pressure environment, the conditions for material drying, separation, molding, and storage are changed, solving various industry pain points such as deterioration, oxidation, and loss of activity caused by high-temperature processing and atmospheric storage. With high cost-effectiveness, it has become the basic supporting equipment for vacuum processes in various industries.
