users who are familiar with vacuum packaging machines know that insurance is mainly to protect the equipment from damaged parts, but recently some users have reported that vacuum packaging machines frequently burn insurance. why is this? the following is a summary of the reasons and solutions for the frequent burning of insurance by vacuum packaging machines based on past experience.
1. cause of failure: the viscosity of the vacuum pump oil is too high
solution: replace the vacuum pump oil
2. the cause of the failure: the motor is reversed
workaround: change the phase sequence
3. reasons for failure: the weather is too cold and the viscosity is too high
solution: run several times after starting the machine or change the low-viscosity vacuum pump oil
4. cause of failure: too much oil in vacuum pump
solution: drain the excess oil
5. the cause of the failure: the exhaust filter is blocked
solution: replace the exhaust filter
6. cause of failure: there is a short circuit and overcurrent
solution: find the cause and fix
