Rotary Vane Vacuum System for Automation & Robotics Lines

Shanghai Puyan Machinery Equipment Co., Ltd.

Puyan Machinery customized a vacuum system for an automation equipment manufacturer in Chongqing to ensure stable operation of its industrial robot production line. In the field of industrial robot and automated machine tool manufacturing, vacuum systems are widely used for parts gripping, workpiece clamping and positioning, suction cup handling, and other processes, requiring high stability and fast response of negative pressure. Recently, Shanghai Puyan Machinery Equipment Co., Ltd. successfully delivered a customized rotary vane vacuum system to an automated machine tool and industrial robot manufacturer in Chongqing, effectively solving the customer's problems of insufficient centralized air supply and frequent pressure fluctuations after production line expansion.

Application of Puyan rotary vane vacuum system in automated production line

Project Background: High Requirements for Vacuum Systems in Automation Equipment Manufacturing

The customer is primarily engaged in the R&D and production of industrial robot bodies, automated machine tools, and intelligent production line solutions. Processes such as machining clamping of robot components, suction cup handling on assembly lines, and air tightness testing during finished product inspection all require a continuously stable negative pressure supply.

With the expansion of production lines and increased robot output, the customer's original decentralized single-pump air supply method gradually revealed its shortcomings: insufficient pumping speed caused significant pressure drops when multiple workstations used vacuum simultaneously, and the lack of buffering and automatic control led to frequent pressure fluctuations, affecting assembly efficiency and product consistency. The customer explicitly requested a centralized rotary vane vacuum system with adequate pumping speed, buffering capacity, and intelligent control functions to meet the round-the-clock continuous operation requirements of the production line.

Puyan Solution: Puyan PV100 Rotary Vane Vacuum Pump + 100L Buffer Tank + Lifu Digital Pressure Switch + Puyan Control Panel

After conducting an on-site survey, the Puyan Machinery technical team customized the following configuration based on the air usage characteristics of the automated production line:

  • Core Vacuum Source: Puyan PV100 Rotary Vane Vacuum Pump. This pump offers a pumping speed of 100 m³/h and an ultimate vacuum below 0.5 mbar. It features high-precision vanes and forced oil lubrication, providing smooth operation, low noise, and suitability for long-term continuous operation in an automation workshop.
  • Buffering System: 100L buffer tank. Effectively smooths out vacuum fluctuations, ensuring stable pressure at all usage points. The tank comes standard with a drain valve and a vacuum gauge port. Its compact design saves valuable workshop installation space.
  • Control and Monitoring: Lifu digital pressure switch + Puyan control panel. The Lifu digital pressure switch displays the system vacuum in real time and supports upper and lower limit pressure settings for automatic start-stop control. The Puyan control panel integrates overload and phase-failure protection, offering convenient operation, safety, and reliability.

The complete system underwent program testing and airtightness testing before leaving the factory. On-site installation only required connection to the main pipeline and power supply, with no complex on-site commissioning needed.

Project Results: Stable Centralized Air Supply, Significantly Improved Production Line Efficiency

Since the rotary vane vacuum system was put into operation, the customer's production workshop has reported significant improvements:

  1. Stable Vacuum: Even when multiple machining clamping and suction cup handling workstations used vacuum simultaneously, the system vacuum level remained consistently within the set range, with no workpiece loosening or handling detachment caused by insufficient pressure.
  2. Intelligent Automatic Operation: By setting upper and lower start-stop limits on the digital pressure switch, the system automatically starts and stops based on the total air demand of the main pipeline, avoiding prolonged idle operation and effectively reducing energy consumption.
  3. Efficient and Convenient Centralized Air Supply: One system replaced multiple previously decentralized small pumps, improving workshop space utilization, making the piping layout more organized and standardized, and simplifying maintenance management.
  4. Easy Maintenance: The PV100 pump has a long maintenance interval. Combined with the buffer tank's ability to trap impurities, the maintenance burden on the equipment department has been greatly reduced.

The customer's equipment manager commented: "After installing Puyan's rotary vane vacuum system, the workshop vacuum pressure has been consistently stable, with no pressure drop issues. The digital display panel is clear and easy to read, allowing operators to monitor the system status at any time."
