| "Damage or sticky silicone foreign body | clean-up, replacement silicone rubber | |
| "Linoleum is damaged or a foreign body stuck | clean, replace linoleum | |
| Inside pocket is not clean enough | clean pocket | |
| Not inflatable Or inflated adverse (If there is) | Inflation time is too short or too long | to shorten or lengthen the time inflation |
| Cylinders are empty or nearly empty | Cylinders are empty or nearly empty | |
| replacement cylinders Cylinders is not open | to open the valve | |
| Inflation pressure setting error | 检"Check whether the pressure gauge or secondary to an atmospheric pressure (1-AT0). Alert! Mixed gas pressure at any time can not exceed 1 atm. | |
| Vacuum chamber vacuum residual gas is normal but the bag is always | bad heating plate reset Heating plate with silicone strip spacing is too large or too small | repair to the reset and flexible. Adjust spacing. |
2, the vacuum pump failure and troubleshooting
| Symptom | Cause | Solution | |
| Pump starting current or operating current is too large | Pump oil or oil overfilled wrong type | check the oil level or oil type | |
| The temperature is low, the oil viscosity is too high | Replacing suitable vacuum pump oil | ||
| "Exhaust filter clogging | Clean or replace the filter | ||
| Pump is running when the temperature is too high | pumping too much or too little | check and adjust the oil level | |
| Heat bad | Clean pump and motor heat sink to improve the environment ventilation. | ||
| Unusual noises pump in operation | Transmission Parts badly worn or loose "" | to identify and timely repair of defective parts | |
| Pump running in the wrong direction | corrective steering (three phase power) | ||
| Smoke or exhaust vents Droplets | Pumping too much | let go too much pump oil | |
| Exhaust filter installed malposition or material rupture | Reinstall or replace the exhaust filter | ||
| Exhaust filter clogging | Clean or replace the filter | ||
