I. Product Overview
The 4.5kW micro-oil lubricated screw
Vacuum Pump is a compact, moderately powerful vacuum generating device. It innovatively combines the stability and reliability of screw technology with the efficient cooling performance of oil lubrication and sealing, providing a vacuum solution for industrial applications that combines cleanliness and efficiency.
As a new type of vacuum equipment using a screw design, its core working principle is to achieve gas extraction by periodically changing the inter-tooth volume through the synchronous counter-rotation of a pair of asymmetrical screw rotors. The most significant technical feature of the equipment is the use of a small amount of lubricating oil (oil content < 2PPM) to form a sealing oil film. This combines the cleanliness advantages of dry vacuum pumps with the high efficiency characteristics of oil-lubricated pumps, making it widely suitable for industrial fields with strict vacuum requirements.
II. Core Advantages
High Efficiency and Energy Saving, Low Operating Costs
Compared to traditional vacuum pumps, this equipment achieves an energy saving rate of over 30% and a volumetric efficiency of up to 95%, outputting a stable vacuum with lower energy consumption. Long-term use can significantly reduce enterprise operating costs. Some advanced models (such as the Atlas Copco GHS VSD+ series) are equipped with variable frequency drive technology to further optimize energy consumption and adapt to vacuum requirements under different working conditions. Low-noise operation, adaptable to multiple scenarios: The equipment's operating noise is controlled at 55-85dB, far below the industry average for similar products, reducing noise interference to the production workshop environment. It is especially suitable for precision manufacturing and pharmaceutical production scenarios where a high level of comfort is required. Simplified structure, convenient maintenance: The overall design is simple, with a reasonable layout of core components, requiring no complex operations for daily maintenance. Coupled with a reliable oil lubrication system, it effectively reduces wear on internal components, lowers the failure rate, and alleviates the operational and maintenance burden on enterprises. Strong environmental adaptability, wide working condition compatibility: It possesses excellent anti-interference capabilities and can stably handle complex working conditions containing water vapor, dust, or corrosive gases without the need for additional pretreatment equipment, greatly improving operational flexibility and adapting to the production needs of multiple industries. Stable, reliable, and long service life. The screw technology itself offers advantages such as smooth operation and low vibration. Combined with the friction-reducing protection of the oil lubrication system, the overall lifespan of the equipment is significantly extended, meeting the needs of long-term continuous operation in industrial scenarios and reducing equipment replacement frequency and investment costs. III. Applicable Scenarios. This equipment, with its comprehensive advantages of "cleanliness + high efficiency + stability," is widely used in fields with strict vacuum environment requirements. Core application scenarios include: Pharmaceutical industry: freeze dryer vacuum systems, solvent recovery processes, and creating vacuum environments for pharmaceutical packaging; Chemical industry: corrosive gas treatment, easy-to-condense medium transfer, and reactor vacuum control; Semiconductor industry: ensuring high-cleanliness vacuum environments in wafer processing, coating processes, and chip manufacturing; General industry: long-term continuous operation scenarios such as food packaging vacuum preservation, electronic display production, and oil and gas recovery in oil extraction. IV. Selection and Usage Recommendations. Confirm Technical Parameter Matching. Before selection, refer to the detailed technical manual provided by the manufacturer, focusing on verifying key parameters such as pumping speed, ultimate vacuum, and interface size to ensure consistency with actual production process requirements and avoid affecting production efficiency due to parameter mismatch. **Prioritize Oil Lubrication System Maintenance:** Clearly define the oil change interval and recommended lubricant type. Strictly adhere to the requirements for using compliant oils and changing them regularly. This is crucial for ensuring stable pump performance and extending service life.
**Assess Supplier Service Capabilities:** Prioritize suppliers with comprehensive after-sales service systems to ensure timely technical support and a stable supply of spare parts, preventing production stoppages due to equipment malfunctions.
**Comprehensive Lifecycle Cost Consideration:** In addition to initial purchase costs, it's essential to calculate the long-term energy consumption and maintenance costs of the equipment. While high-efficiency, energy-saving models may have a slightly higher initial investment, their energy and maintenance cost advantages significantly reduce the total investment in the long run, resulting in higher cost-effectiveness.
