1.The RV series vacuum pumps are small oil - sealed rotary vane pumps, which have become the industry standard for primary pump scientific applications. The following is a detailed introduction:
- Performance Characteristics:
- High - quality Vacuum Performance: These pumps can provide a high ultimate vacuum, with pumping speeds ranging from 3 to 12 m³/h, which can meet different vacuum requirements.
- Strong Vapour Handling Capacity: Equipped with a mode selector and a two - position gas ballast, it can handle 60 g/h or a class - leading 220 g/h (290 g/h for RV12) of water vapour, which is very suitable for wet pumping applications such as freeze - drying, extraction, filtration, and gel drying.
- Quiet Operation: The noise level is as low as 48 dB(A), which is achieved through a lot of work on the drive train and motor, greatly reducing the intrusive frequency.
- Unique Design:
- Fast - acting Inlet Valve: It can act within 0.4 seconds after the pump stops, preventing oil mist from entering the system and providing reliable and safe operation for the system.
- High - polymer Blades: The blades are made of high - polymer materials with a large diameter, and the oil circuit is easy to clean.
- Efficient Lubrication: It adopts high - pressure lubrication, which can ensure the normal operation of the pump and prolong its service life.
- Application Fields: In high - vacuum mode, it is suitable for analytical instruments, electron microscopes, physics research, as a backing pump for turbo pumps, and leak detection applications. In high - throughput mode, it can be used for distillation, laboratory furnaces, backing vapor pumps, solvent concentration, freeze - drying, and other drying applications.
2.The RV series vacuum pumps are widely used in various fields due to their excellent performance, and the specific application areas are as follows:
- Analytical Instruments: It is suitable for analytical instruments such as gas chromatography - mass spectrometry (GCMS) and liquid chromatography - mass spectrometry (LCMS). In the analysis process, it can provide a stable vacuum environment, helping to improve the accuracy and sensitivity of the instrument, and is conducive to the separation and detection of substances.
- Electron Microscopy: It is an ideal vacuum - providing equipment for electron microscopes, including transmission electron microscopes (TEM) and scanning electron microscopes (SEM). A high - vacuum environment can ensure the normal operation of the electron beam, reduce the scattering of electrons by gas molecules, and help obtain high - resolution images.
- Material Coating: In the material coating process, such as the preparation of thin - film materials, the RV series vacuum pumps can pump out the gas in the coating chamber to create a high - vacuum environment, which is beneficial to the uniform deposition of coating materials on the substrate surface and improves the quality and performance of the coating.
- Vacuum Drying: It is widely used in freeze - drying, gel drying and other processes. For example, in the freeze - drying of drugs, it can quickly remove water and other solvents, maintain the activity and quality of drugs, and is also applicable to the drying treatment of biological samples, food, etc.
- Distillation and Extraction: In chemical experiments and industrial production, it is used for distillation and extraction operations. It can reduce the boiling point of the liquid, make the distillation and extraction process proceed more efficiently, and is helpful for the separation and purification of substances.
- Turbo Pump Backing: As a backing pump for turbo - molecular pumps, it can work together with turbo - molecular pumps to obtain a higher vacuum degree, which is widely used in occasions requiring high - vacuum, such as semiconductor manufacturing, vacuum electron devices, etc.
- Gas Bottle Filling and Emptying: It can be used for filling and emptying gas bottles, and can quickly adjust the gas pressure in the bottle to meet the use requirements of different gases, and is widely used in laboratories, industrial production and other occasions where gas bottles are used.
- Research and Development: In scientific research institutions and enterprise R&D centers, it is used in a large number of physical, chemical, material science and other research projects, such as gas or plasma dynamics research, vacuum heat treatment of materials, providing a reliable vacuum environment for scientific research experiments.
