This 30-liter vacuum machine is specially used to remove bubbles from liquid PVC material or Liquid silicone material, and its working principle and precautions are as follows:
Core Functions and Scenarios
• Principle: The vacuum pump evacuates the sealed chamber (with a volume of 30 liters) to a negative pressure state. Bubbles in the liquid expand and float due to the reduced air pressure, achieving degassing for liquid materials like resins, adhesives, and coatings.
• Typical Applications:
1, Degassing epoxy resin before pouring to avoid bubbles after curing;
2 , Vacuum degassing of fruit juices and sauces in the food industry to extend shelf life;
3. Processing small liquid samples with laboratory vacuum degassing devices.
This PVC vacuum machine is made by Jinyu Machinery, specially designed for making PVC or Silicone Products. We also have different types of PVC machines or Silicone machines for the whole industry production line equipment. PVC produts making machine, silcione products making machine, rubber products making machine
Matching Key Equipment Parameters
• Pumping Speed: If the liquid volume is close to 30 liters, a pump with a pumping speed ≥30 L/min is required to establish vacuum within a reasonable time (e.g., complete degassing within 10 minutes).
• Ultimate Vacuum: Liquid degassing typically requires a low vacuum level (e.g., below 100 Pa). The higher the ultimate vacuum (e.g., 10 Pa for the pump), the more thorough the bubble removal effect.

Precautions
• Anti-liquid Backflow: During liquid degassing, violent bubble overflow may cause liquid backflow. Install check valves or buffer tanks before the pump to prevent damage to the vacuum pump (especially rotary vane pumps, as liquid entry can corrode the pump body).
• Temperature Influence: Some liquids (such as hot-melt adhesives) need heating to reduce viscosity and promote bubble escape, requiring a temperature control device.
• Oil Consumption Maintenance: For oil-lubricated vacuum pumps (e.g., rotary vane pumps), trace water vapor or volatile substances may enter the pump during liquid degassing. Regularly check the oil consumption to avoid oil emulsification and failure.
Conclusion
When using a 30-liter vacuum machine for liquid degassing, match the pump's pumping speed and vacuum level according to the liquid properties, and implement anti-backflow protection to ensure safe and efficient operation.
