· Oil Lubricated Rotary Vane Vacuum Pump:
The image should focus on highlighting the design features of the oil-lubricated rotary vane vacuum pump, showing its sturdy construction, pump body, and oil lubrication system, suitable for various industrial applications.
- Working Principle: The single-stage oil rotary vane pump mainly consists of components such as the stator, rotor, vanes, cylinder body, and end cover. When it operates, the rotor is eccentrically installed within the stator. As the rotor rotates, the vanes, under the action of centrifugal force and spring force, closely adhere to the cylinder wall and reciprocate within the rotor slots, dividing the pump chamber into several small chambers with variable volumes. Through processes such as suction, compression, and exhaust, it achieves the extraction of gas and establishes a vacuum146.
- Structural Features:
- Compact and Lightweight: The overall structural design is relatively compact, with a small volume and light weight, making it easy to install and move, and capable of adapting to different working environments and space requirements. For example, in some small laboratories or production sites with limited space, the small size of the single-stage oil rotary vane pump allows for convenient placement and use.
- Good Sealing Performance: It adopts an oil seal structure, and through the sealing effect of the pump oil, effectively prevents gas leakage, ensuring the vacuum degree and pumping performance of the pump. Good sealing also helps to reduce the loss of pump oil and environmental pollution.
- Durable Components: Key components such as the rotor and vanes are usually made of high-quality materials, possessing high strength and wear resistance, capable of withstanding long-term high-speed operation and extending the service life of the pump.
- Performance Characteristics:
- Fast Pumping Speed: Within a certain pressure range, the single-stage oil rotary vane pump can quickly extract a large amount of gas, improving work efficiency. For instance, in some processes that require rapid establishment of a vacuum environment, such as vacuum packaging and vacuum adsorption, its fast pumping speed can meet production requirements.
- Relatively High Vacuum Degree: Although the vacuum degree of the single-stage oil rotary vane pump is slightly lower than that of the two-stage rotary vane pump, it can still achieve a relatively high vacuum degree in general industrial and scientific research applications, meeting the requirements of most processes for the vacuum environment. Typically, its ultimate pressure can reach approximately 0.1 - 1 Pa.
- Stable and Reliable Operation: After years of technological development and improvement, the operational stability of the single-stage oil rotary vane pump has been significantly enhanced. Under normal working conditions, it can operate stably for a long time, reducing production interruptions and losses due to equipment failures.

- Industrial Production:
- Vacuum Packaging: In industries such as food and pharmaceuticals, the single-stage oil rotary vane pump is used in vacuum packaging machines to extract the air inside the packaging container, extending the shelf life of the product, preventing food spoilage and drug moisture absorption, while also making the packaging more compact and aesthetically pleasing.
- Vacuum Coating: For processes such as metal coating and plastic coating, which require a high-vacuum environment, the single-stage oil rotary vane pump can be used as the forepump of the coating equipment to provide the necessary vacuum conditions for the coating process, enabling the coating material to be evenly deposited on the object surface and form a high-quality coating layer.
- Vacuum Drying: In the drying processes of industries such as chemical engineering, pharmaceuticals, and food, using a single-stage oil rotary vane pump to create a vacuum environment can lower the boiling point of water, accelerate the evaporation rate of moisture, improve drying efficiency, and avoid the oxidation and deterioration of the product during the drying process.
- Scientific Research Experiments:
- Laboratory Instruments: Many laboratory instruments, such as mass spectrometers, electron microscopes, and vacuum glove boxes, require a vacuum environment to operate. The single-stage oil rotary vane pump can provide a stable vacuum source for these instruments, ensuring their normal operation and the accuracy of experimental data.
- Materials Research: In the field of materials science, researchers need to conduct material preparation, testing, and analysis work in a vacuum environment. The single-stage oil rotary vane pump can meet the vacuum degree requirements of these experiments, providing good experimental conditions for materials research.
- Other Fields:
- Medical Equipment: In some medical devices such as vacuum aspirators and dental treatment equipment, the single-stage oil rotary vane pump is used to generate negative pressure to achieve functions such as suction, providing convenience for medical operations.
- Electronic Manufacturing: In the production process of electronic components, such as semiconductor chip manufacturing and electron tube manufacturing, a high-purity vacuum environment is required. The single-stage oil rotary vane pump can be part of the vacuum system to provide the necessary vacuum conditions for electronic manufacturing, ensuring the quality and performance of the products.
