Product Description

Basic Information
The 2X-70A is a dual-stage rotary vane vacuum pump. It belongs to the 2X series, designed for various applications that require vacuum creation and maintenance.

 

Working Principle
The pump operates based on the rotary vane mechanism. Inside the pump, there is an eccentrically installed rotor. The rotor slots house the vanes. As the rotor rotates, the vanes slide in the slots and make contact with the inner wall of the stator. This movement divides the pump chamber into variable-volume spaces, and by continuously changing these volumes, the pump sucks in and discharges gas to achieve vacuuming.
 
Applications
- Vacuum Coating: It is widely used in the vacuum coating process to provide a high-quality vacuum environment for coating materials onto substrates.
- Vacuum Heat Treatment: Ensures a precise vacuum condition for heat treatment processes, preventing oxidation and other unwanted reactions.
- Vacuum Smelting: Applied in vacuum smelting to remove impurities and gases in the metal, improving the quality of the smelted metal.
- Electronics Industry: Used in the production of electronic components such as vacuum tubes and bulbs to ensure their performance and lifespan.
- Chemical Industry: In chemical processes like vacuum drying, filtration, and reaction, the 2X-70A helps to control the reaction environment and improve product quality.
 
Features and Advantages
- High Pumping Speed: With a pumping speed of 70 L/s, it can quickly remove gas from the sealed container, improving production efficiency.
- Low Ultimate Pressure: The ultimate partial pressure performance is very excellent, which meets the requirements of high-vacuum processes.
- Gas Ballast Valve: Except for the 2X-4A type, it is equipped with a gas ballast valve, which can pump out a small amount of water vapor and prolong the service life of the pump oil.
- Energy-saving Design: The vacuum pump has multiple suction holes, which helps to save electricity.
- Wide Temperature Range: It can work continuously at temperatures between 5 and 40°C and with an inlet pressure of less than 1330 Pa.

The working functions of the 2X-70A rotary vane vacuum pump mainly include the following aspects:
 
Gas Extraction and Exhaust
- Rapid Gas Extraction: It can extract the gas inside the sealed container within a short period, rapidly reducing the pressure inside the container to achieve the required vacuum degree. For example, in vacuum coating equipment, it can quickly make the coating chamber reach the vacuum condition, creating a suitable environment for the coating process.
- Continuous Exhaust: It can continuously discharge the gas from the system to maintain the vacuum state of the system. In the production of electron tubes, it can continuously discharge the gas inside the electron tube, ensuring the high vacuum degree inside the electron tube and the stable performance of the electron tube.
 
Vacuum Maintenance
- Stable Vacuum Environment: In various processes that require a vacuum, such as vacuum heat treatment and vacuum smelting, the 2X-70A rotary vane vacuum pump can maintain a stable vacuum degree by continuously extracting gas, preventing the outside air from entering, avoiding adverse reactions such as oxidation of the materials being processed, and ensuring the smooth progress of the process and the product quality.
- Precise Vacuum Degree Control: With its stable performance and adjustable gas extraction rate, it can precisely control the vacuum degree according to different process requirements, meeting a variety of process requirements from low vacuum to high vacuum.
 
Gas Transmission and Separation
- Gas Transmission: It can serve as a power source for gas transmission, transferring gas from one container to another. In the gas transportation process in the chemical industry, it can transport the gas generated by the reaction to the designated processing equipment or storage container.
- Simple Gas Separation: By taking advantage of the differences in the transmission characteristics of different gases inside the vacuum pump, it can achieve simple gas separation to a certain extent. For example, in a mixed gas, it can preferentially extract some gases that are easily extracted, achieving preliminary gas separation.
