How to deal with the situation that vacuum can't be pumped out when using the reactor
Source: Stainless steel reactor, resin reactor, pressure vessel tank - Wuxi Huaxuan Equipment Technology Co., Ltd |Published on: July 27, 2020

There are two conditions for the reactor to be in vacuum state
1. The vacuum pump is used to pump material when discharging.
2. The reaction process should not be affected by other gases such as oxygen.
In the process of using the reactor, if the vacuum can not be pumped up, the following methods can be used for troubleshooting:
1. The container is saturated with vapor.
2. The capacity of vacuum pump decreased.
3. Vacuum tube, loose joint, vacuum gauge leakage.
4. When the instrument is used for pressure maintaining test, shut off the external valve and pipeline without solvent, keep the pressure for one minute, and the pointer of vacuum gauge shall not move, indicating good air tightness. Otherwise, see the right.
5. There are impurities in the discharge valve and pressure control valve.
6. The glass is broken.
Corresponding solutions:
1. Empty the solvent and test the empty bottle.
2. Change oil (water) of vacuum pump, clean and repair.
3. Check and remove section by section along the vacuum pipeline.
4. Reassemble, clean the glass grinding mouth, apply vacuum silicone grease, align and tighten the flange port; replace the invalid sealing ring.
5. Cleaning.
6. Replace the glass or repair it.
