maybe the leather pad is damaged or the contact wall is not smooth. This can be detected by a leak detector

go to Baidu app to view

 I'm glad to answer your question. I'm sorting out relevant information and waiting patiently

 there are many reasons for the unclean vacuum pumping of the vacuum packaging machine. The main reasons are: the evacuation time is too short. The vacuum pump is aged or the maintenance is not in place. Vacuum work is not well sealed, and there is air leakage during vacuum pumping. The power of the vacuum pump is too small and does not match the actual pumping speed ratio, so it can not fully vacuum

 I hope my answer can help you 

 solution: lengthen the vacuum pumping time. When replacing the vacuum pump, pay attention to the timely maintenance and replacement of the vacuum pump oil. If the maintenance has not been done for a long time, please clean up the oil in the vacuum pump before replacement. (generally, the first maintenance is to work continuously for 300 hours, and then work continuously for 500 hours for maintenance). Check whether there is air leakage in the vacuum working room. If there is air leakage, replace the sealing strip in time. The vacuum pump is too small to achieve the ideal vacuum effect, so we can only replace the vacuum pump
