Causes and solutions of vacuum packaging machine failure

1¡¢ Pump does not start
Main reasons: 1. Insufficient voltage or fuse blown; 2. Pump or motor stuck.
2¡¢ Pump stuck in operation
The basic reasons are: 1. Long time running under wrong steering; 2. Blade breaking or deformation; 3. Lack of oil on friction surface.
3¡¢ The vacuum pump can not pump vacuum:
The main reasons are: 1. The vacuum pump is not started; 2. The vacuum chamber cover is not completely closed; 3. The vacuum time relay is damaged; 4. The valve between the pump and the vacuum chamber is not opened; 4;
4¡¢ The vacuum chamber can not reach the limit vacuum degree
The main reasons are as follows: 1. The pump can not reach the limit vacuum; 2. The pipe leaks; 3. The pipe joint is loose; 4. The small gas chamber (or air bag) leaks; 5. The sealing ring of the vacuum chamber is damaged or scratched; 6. The large sealing ring of the vacuum chamber or the upper plane of the vacuum chamber is uneven; 7. The electromagnetic valve leaks, such as the valve of the main pipe, the inflation valve and the air guide valve; 8. The vacuum pumping time is not enough.
5¡¢ Vacuum system leak detection: turn on the vacuum pump, pump to the limit vacuum, then turn off the pump and listen to whether there is a "silky" sound everywhere. The sound producing place is the leakage part. Check for looseness, poor sealing and cracks in parts. Generally, it is not easy for the seal to leak. If the vacuum degree rises after the application of sealing mud, it indicates that there is air leakage at the application place, and the maintenance of valves and pumps is troublesome, so it is necessary to check them. In case of local leakage of metal parts of vacuum packaging machine, gy-340 anaerobic adhesive can be used to stop the leakage. Anaerobic adhesive is a single component and does not need to be mixed in proportion. It is easy to use. After curing, it has compact structure, stable performance and reliable sealing.
