1. The pump body changes oil for a long time
If there is no oil change for the pump body for a long time or the packaged goods contain water, the water will enter the engine oil and cause an impact, which will cause the food vacuum packaging machine to fail to operate normally and the vacuum degree cannot reach.
2. Poor sealing
Some vacuum packaging machines contain sealing strips made of sponges. The sealing strips need to be checked and replaced regularly, and the problems of sealing strips will directly affect the required vacuum degree.
3. Smoke or air leakage from the vacuum pump
When this problem occurs, it is necessary to clean the vacuum pump in time, replace the discharge filter, and check whether the check valve works normally.
