Description

XZ Direct-coupled Rotary Vane Vacuum Pump Product Details

1. Product Overview

The XZ direct-coupled rotary vane vacuum pump is a small-sized, precise, energy-saving, low-noise and environmentally friendly single-stage oil-sealed vacuum equipment. Adopting newly optimized structural design and exquisite manufacturing technology, it effectively solves the common shortcomings of traditional small vacuum pumps, such as high energy consumption, loud noise, easy pollution and insufficient durability. With an integrated motor direct-coupled structure, the pump features compact volume, light weight, sensitive start-up and stable operation, serving as the basic core equipment for vacuumizing small closed cavities and building micro vacuum environments.

Different from conventional large-flow industrial vacuum pumps, this model focuses on precise micro-vacuum operation. It balances high-efficiency air extraction and environmental protection performance, with lower energy consumption, quieter operation and longer service life. The exclusive anti-pollution structure effectively prevents vacuum oil backflow and medium contamination, fully protecting the cleanliness of processed equipment and workpieces. Compatible with standard single-phase 220V power supply, it is plug-and-play with simple operation. It can work independently for various small vacuum tasks or serve as a front-stage pump for high-end vacuum equipment, widely used in refined vacuum processes in laboratories, precision manufacturing, refrigeration maintenance and light industry.

2. Core Product Advantages

Precision Direct-coupled Structure, Compact, Efficient and Plug-and-Play

The integrated direct-drive design eliminates redundant transmission parts, realizing compact layout, flexible movement and no occupation of working space. Compatible with universal single-phase municipal power supply, it requires no complicated wiring and debugging. It starts stably with fast response and smooth operation, perfectly suitable for small workstations, laboratory desktop use and portable maintenance scenarios, making it an ideal choice for lightweight vacuum operations.

Low Noise, Energy Saving and High Durability for Long-term Stable Operation

Equipped with optimized rotary vane structure and oil sealing technology, the pump greatly reduces operating friction loss and achieves three core advantages: low energy consumption, ultra-low noise and low vibration. Compared with traditional small vacuum pumps, it effectively reduces power consumption and eliminates high-frequency abnormal noise. The enhanced pump cavity features excellent wear resistance and corrosion resistance, with strong fatigue resistance and frequent start-stop adaptability, supporting long-term continuous stable operation and greatly reducing failure rate and replacement cost.

Clean Anti-pollution Design for High-precision Working Conditions

Specially optimized for high-cleanliness scenarios such as precision experiments, medical instruments and light industry forming. It effectively suppresses vacuum oil atomization, backflow and leakage during operation, avoiding oil pollution to cavities, workpieces and experimental media. It guarantees high cleanliness of the vacuum environment and fully adapts to refined working scenarios with strict requirements on precision and cleanliness.

Dual-purpose Design for Independent Operation and Front-stage Matching

The pump features strong functional compatibility with dual working modes. It can independently complete vacuum extraction of various small closed containers to meet conventional micro-vacuum process demands. Meanwhile, it can be used as a front-stage pre-vacuum pump for high-end equipment such as oil booster pumps, oil diffusion pumps and molecular pumps, rapidly building pre-vacuum environments to ensure stable operation of precision vacuum systems, showing far stronger adaptability than ordinary small vacuum pumps.

Ultra-simple Maintenance System, Zero-threshold Daily Care

With a simple overall structure and few vulnerable parts, the pump is equipped with standardized oil drain screws and visible oil gauges, making oil level inspection and oil replacement intuitive and convenient. Daily maintenance only requires dust prevention, regular oil supplement and oil replacement to maintain optimal working conditions. No professional skills or complex tools are needed, realizing extremely low maintenance threshold and adapting to long-term regular use.

3. Working Principle

The XZ direct-coupled rotary vane vacuum pump operates based on the single-stage oil-sealed positive displacement ventilation principle. The motor directly drives the rotor to rotate at high speed. Eccentrically arranged rotary vanes closely fit the inner wall of the pump cavity under centrifugal force, causing periodic volume expansion and contraction of the pump cavity. During the expansion process, air in the closed container is stably sucked into the pump cavity; during the contraction and compression process, the gas is pressurized and discharged in order, continuously extracting air from the closed space and forming stable vacuum negative pressure.

Special vacuum pump oil provides full-process sealing, lubrication and cooling for the equipment. The oil seal structure effectively isolates external air and impurities to ensure stable vacuum degree. After shutdown, pressure balance operation can balance the internal and external air pressure of the pump, avoiding component damage caused by long-term negative pressure compression, effectively extending service life and maintaining stable and high-precision vacuum output for a long time.

4. Application Scenarios

With the core strengths of compact precision, mute energy saving, clean anti-pollution performance, simple maintenance and strong front-stage compatibility, the pump is specially designed for various small, precise and lightweight vacuum operations, accurately meeting the differentiated demands of segmented industries.

Laboratory Scientific & Chemical Experiments: Suitable for laboratory small-scale vacuum defoaming, vacuum drying, vacuum extraction and micro-cavity negative pressure experiments. It provides stable vacuum precision and oil-free clean environment, fully adapting to various high-precision physical and chemical experimental conditions.

Refrigeration and Electrical Maintenance: Used for vacuum pumping, dehumidification and pipeline negative pressure leakage detection of air conditioners, refrigerators and refrigeration units. It is portable and stable in air extraction, serving as special supporting equipment for the refrigeration maintenance industry.

Medical and Precision Instrument Industry: Applied to medical suction devices, negative pressure supporting for small precision instruments and vacuum environment construction for testing equipment. With low noise and high cleanliness, it meets the strict operating standards of medical and precision equipment.

Light Industry Manufacturing: Suitable for small-product vacuum packaging, plastic vacuum blister forming and negative pressure auxiliary operation of printing machinery. Its small size perfectly adapts to assembly line small-station operation.

High-end Vacuum Equipment Matching: Provides front-stage pre-vacuum for large vacuum equipment such as oil booster pumps, diffusion pumps and molecular pumps, helping high-end equipment quickly stabilize working conditions and ensuring stable operation of precision vacuum systems.

5. Working Restrictions & Operation Specifications

Prohibited Working Conditions: The pump is only applicable to extract clean, dry, non-corrosive and dust-free conventional air media. It is prohibited to extract gas corrosive to ferrous metals, gas chemically reactive with vacuum oil, as well as high-oxygen, explosive and toxic gas. This equipment is only used for vacuum extraction of closed containers and cannot be used as a gas transmission pump for gas delivery between containers, so as to avoid equipment damage, vacuum failure and potential safety hazards.

Daily Operation Specifications: Block the air inlet during idle shutdown to prevent external dust and sundries from entering the pump cavity and causing wear. Long-term operation will cause vacuum oil turbidity and deterioration; users shall unscrew the oil drain screw to drain dirty oil completely, then tighten the screw and fill clean vacuum pump oil to the midline of the oil gauge. If abnormal vacuum occurs during operation, disassembly and maintenance must be guided by professional personnel; unauthorized disassembly is prohibited. Check the oil level regularly, supplement oil in case of insufficiency and replace oil in case of contamination. Avoid long-term large-displacement exhaust operation; release pressure and balance internal and external pressure after exhaust to protect equipment components.
