Vacuum packaging machine failure causes and solutions

Vacuum packaging machine failure causes and solutions

The modern vacuum technology is mature and the application effect is remarkable. It has been recognized in various industries, not only to keep the product fresh and quality, but also to resist mechanical pressure, reduce oscillation, and facilitate long-distance transportation. Therefore, it can maintain the food original more effectively. Some color, aroma, taste, shape and nutritional value. Vacuum packaging opportunities often encounter the following failure problems during use, without panic, and understand the solution.

1. What should I do if the vacuum packaging machine does not pump vacuum or if the vacuum is not high?

1) Whether the vacuum pump is reversed, check whether the direction of rotation of the vacuum pump matches the arrow clicked on the vacuum pump, and it must be adjusted correctly;

2) The single-chamber vacuum packaging machine that has just been purchased may not be gentle enough between the upper cover and the lower cover of the vacuum chamber during use. We should use a little force when covering the vacuum chamber to make the upper cover of the vacuum chamber match the panel. ;

3) The travel switch is not in place and adjust the position of the travel switch limiter.

4) The time relay is out of control and replaced.

5) The bleed valve is not closed tightly, causing leakage, and check the venting solenoid valve and spool (rubber). Is there any wear, contamination or spool center offset?

6) Check whether there are any leaks or loose parts in the pipeline.

2, the heat seal quality is not good

1) Check if the mouth of the package is clean and avoid contamination at the seal.

2) Check if the nickel-chromium band is working properly, whether there is a short circuit or open circuit.

3) Whether the heat sealing temperature and heat sealing time are properly selected.

4) Check if the airbag under hot pressing leaks.

5) The heat sealing solenoid valve is not working properly.

3, can not deflate after vacuuming, vacuum chamber can not open.

1) The time relay is out of control and the contacts are in poor contact or damaged.

2) No power supply, check the power supply circuit.

3) Check if the bleed solenoid valve is working properly.
