Description

2X Two-stage Rotary Vane Vacuum Pump Product Details

1. Product Overview

The 2X two-stage rotary vane vacuum pump is a high-precision double-stage positive displacement vacuum equipment, adopting a unique high-pressure and low-pressure series dual-cavity structure, which breaks through the low vacuum limit and unstable negative pressure defects of single-stage vacuum pumps. During operation, the low-pressure stage firstly extracts gas from the vacuum container, and the high-pressure stage completes secondary compression and exhaust. When the system vacuum degree reaches the critical value, the high-pressure stage exhaust valve closes automatically, and all gas is transferred to the low-pressure stage for secondary pressurization and discharge, realizing step-by-step gas purification and vacuum stabilization. The ultimate vacuum degree can reach 6×10⁻² Pa with excellent high-vacuum forming performance. It can operate independently with direct atmospheric exhaust, and can also be used as a front-stage pump matched with a vacuum booster pump to upgrade the system vacuum. It is a mainstream high-efficiency vacuum equipment widely used in precision manufacturing, chemical and medical, light industry drying and other high-end vacuum processes.

2. Core Product Characteristics

Two-stage Series Structure with Higher Ultimate Vacuum

The high and low pressure dual-cavity graded pressurization design realizes staged air extraction and secondary compression purification, solving the problems of insufficient vacuum and pressure fluctuation of single-stage pumps. With an ultra-low ultimate vacuum of 6×10⁻² Pa, fast pumping speed and stable pressure building, it can quickly build a high-precision clean vacuum environment, fully meeting the strict vacuum standards of precision experiments, fine processing and high-end manufacturing.

Integrated Dust-proof Design to Prevent Pump Jamming

Equipped with a professional dust-proof device to isolate external sundries and dust particles in advance. All impurities stay outside the dust-proof structure and cannot invade the pump cavity. It fundamentally eliminates common failures such as rotor jamming, equipment stalling and cavity wear caused by dust ingress, ensuring 24-hour continuous and stable operation and greatly reducing shutdown failure rate in mass production.

Innovative Self-cleaning Structure for Efficient Maintenance

It is equipped with a vent valve with porous composite screw, integrating oil passage dredging, impurity removal and water vapor pressure relief functions. No overall disassembly is required. Simply unscrew the composite screw to quickly dredge blocked oil holes and discharge accumulated water vapor and residual impurities inside the pump. The maintenance operation is simple and efficient, avoiding complicated disassembly and greatly improving production continuity and operation efficiency.

Compact, Low-noise and High-adaptability Operation

Adopting optimized flow channel and integrated compact structure, the pump features small size, light weight and strong pumping capacity. It operates with low vibration, ultra-low noise and stable performance, suitable for low-noise working scenarios such as laboratories, clean workshops and closed production lines. It supports direct atmospheric exhaust with simple installation and strong practicability.

Expandable Performance for Ultra-high Vacuum Upgrade

With excellent compatibility and scalability, the pump can be combined with a vacuum booster pump to form a front-stage vacuum unit on the basis of independent operation. The cooperation of continuous stable pumping of the front pump and pressurization of the booster pump further raises the vacuum upper limit of the system, meeting the requirements of higher-standard ultra-precision vacuum processes.

3.Working Principle

The 2X two-stage rotary vane vacuum pump works through the series cooperation of high-pressure and low-pressure cavities. The pump inlet is connected with vacuum equipment or vacuum containers. After startup, a large amount of gas in the container is first sucked into the low-pressure cavity for primary compression. As the system vacuum degree increases continuously, the high-pressure stage exhaust valve plate closes automatically, and the residual gas in the high-pressure cavity is transferred to the low-pressure cavity for secondary pressurization, compression and complete discharge. Through the two-stage graded pressurization and staged exhaust mode, the vacuum environment is continuously purified and the negative pressure value is stabilized to realize efficient and continuous vacuuming. When matched with a vacuum booster pump, the air extraction efficiency is further optimized to build a higher-precision ultra-vacuum system.

4. Application Industries

Relying on the core advantages of two-stage high vacuum, dust-proof and anti-jamming, disassembly-free self-cleaning maintenance, low-noise stable operation and expandable performance, the pump is widely used in high-precision industrial processing and scientific research scenarios with strict requirements for vacuum degree and stability.

Electronic & Lighting Industry: Applied to vacuum packaging of electronic devices, vacuum degassing and vacuum forming of electric light source products, providing a high-purity and stable vacuum environment to ensure processing accuracy and finished product yield.

Refrigeration & Packaging Industry: Used for vacuum pumping and maintenance of refrigeration equipment, vacuum defoaming of daily necessities and automatic vacuum packaging processes, with constant negative pressure and fast forming speed, suitable for continuous assembly line production.

Medical & Chemical Industry: Adapted to laboratory vacuum extraction, negative pressure experiments, medical equipment negative pressure supporting, vacuum drying, dehydration and degassing of chemical materials, meeting the high-clean and high-precision vacuum requirements of scientific research and industrial production.

Light Industrial Manufacturing: Widely used in vacuum treatment of thermos liners, industrial material dehydration, negative pressure drying and vacuum processing of precision workpieces, featuring stable operation and strong working condition adaptability.

5. Usage Restrictions

This equipment is a high-precision special vacuum pumping device, only suitable for clean gas vacuuming operations. It is strictly prohibited to extract excessive oxygen gas, flammable and explosive gas, metal corrosive gas, gas reactive with vacuum oil, and gas containing solid particles and dust impurities, so as to avoid pump cavity wear, rotor jamming, vacuum oil deterioration and equipment damage. Meanwhile, the pump is only used for vacuum pumping, forbidden to be used as a material delivery pump or gas compression pump to prevent equipment failure and potential safety hazards.
