For example, in many food processing operations, vacuum machines are used for vacuum packaging. However, commercial vacuum machines will inevitably malfunction if they are used too hard or are operated improperly. For example, Hong Kong Junhong Repair Center has repaired many vacuum equipment before. Among them, there are many cases of repairing vacuum machines. Next, let’s talk about related maintenance knowledge.
1. There is air behind the commercial vacuum machine
Many of the vacuum machine repair cases that Hong Kong Junhong Repair Center comes into contact with are the cases where there is still air after vacuuming, so the food cannot be preserved in the vacuum. Next, let’s take the case of vacuum machine repair at home as an example. Let’s talk about this How to repair.
(1) Considering that many vacuumed foods have oil stains, you must first check the bag and interface. A very common phenomenon is that the bag cannot be completely sealed due to oil stains on it.
(2) When repairing a home vacuum machine, the sealing strip should also be considered. After cutting off the power supply, first confirm the integrity and elasticity of the sealing strip to ensure that there is no abnormality in the sealing strip.
(3) The next thing to check is whether the vacuum pump is running normally. On the one hand, you need to listen to see if the sound of the vacuum pump is normal. On the other hand, you can use a multimeter to measure the resistance of the pump. If the resistance value is between 1-10 ohms, It means that there is no abnormality in the vacuum pump. Otherwise, if there is a circuit break, the vacuum pump must be checked and replaced.
2. The packaging bag leaks after vacuuming
The case of repairing a vacuum home vacuum machine just introduced was due to incomplete vacuuming. Hong Kong Junhong Repair Center also encountered air leakage after vacuuming. For this, we still need to check the packaging bag interface first. Let’s talk about this next. Maintenance process for this situation.
(1) When checking the packaging bag, you should also check the sealing strip to ensure that the sealing strip is complete and elastic, and check the sealing temperature.
(2) One of the elements that affects the sealing effect is the heating component. Check whether the surface of the heating component is obviously burned, and then use a multimeter to measure the resistance. If the resistance is within the range of 1-10 ohms, it means it is normal.
(3) In fact, pressure problems will also be encountered when repairing vacuum home vacuum machines, so check the pressure regulating device after confirming that there is no problem with heating, and test whether the pressure regulating device is normal. If abnormal, it is necessary to replace the pressure regulating device with a new one.
The above introduction is about cases and maintenance experience sharing when repairing vacuum home vacuum machines. In fact, these problems occur not only in commercial vacuum homes, but also in companies such as Haier and Expo. The maintenance process is Similarly, you can solve it by following the steps.
