Configuring a Vacuum Sealing Machine Vacuum System

The design of a vacuum system is crucial for ensuring optimal performance in vacuum sealing machines. This article outlines the key considerations for configuring a vacuum system, including the selection of equipment, piping, valves, and other components.

Key Considerations in Vacuum System Design
When designing a vacuum system, two primary issues must be addressed:

1. Selection of Main Pump and Components

Based on the gas generation rate, working pressure, ultimate vacuum levels, and pumping time, the type of main pump is determined. This guides the selection of appropriate vacuum components and the configuration of the piping system.

2. Calculating Vacuum Time

It’s essential to calculate the vacuum time for the device, or alternatively, determine the pressure that can be achieved within a specified pump-down duration.

 

Understanding Ultimate Vacuum


The ultimate vacuum that a vacuum chamber can achieve is influenced by several factors. The relationship can be expressed through the following considerations:

* The ultimate vacuum in the vacuum chamber is always less than that of the vacuum extractor.
* This difference is primarily affected by the ratio of gas flow (Q) to the surface area (S). The effective pumping speed near the pumping port plays a significant role.
* The ultimate vacuum is proportional to the amount of leakage and gas present in the vacuum chamber.


Working Pressure Calculation


The working pressure necessary for the vacuum chamber's operation is typically higher than the ultimate vacuum. It can be calculated using the following considerations:

* The work pressure should be set to maximize the economic efficiency of the vacuum extraction equipment.
* Ideally, the working pressure should be at the maximum pumping speed of the main pump, which usually falls within one order of magnitude above the ultimate pressure.
A common guideline is to select a working pressure that is roughly ten times lower than the workload gas generated during the production process.

 

Conclusion
Designing an efficient vacuum system for sealing machines requires careful consideration of various factors, including the selection of pumps, calculation of vacuum times, and understanding the relationship between ultimate vacuum and working pressure.
