In the daily use of the industrial fermenter mixing reactor, with the passage of time, sometimes there will inevitably be some minor problems, but sometimes if we directly contact the manufacturers to come to deal with, often found that these problems are very simple can be resolved.First, the industrial fermenter mixing reactor suddenly appeared noise
In general, the reactor has a noise, most of the reason is stirrer friction inside the kettle, such as the snake tube, thermometer tube or wall stirrer loose, lining drum and stirrer impact, stirrer bending or bearing damage.
Common solutions are:
1. Reactor shutdown maintenance, correction, so that the mixer and accessories have a certain spacing.
2. Stop running, check, fasten the bolts.
3. Repair the part or replace it.
4. Repair, or replace the mixing bracket bearings of the reactor
In general, there are some possible reasons that the motor current of the reactor exceeds the rate or set value: bearing damage, low temperature inside the reactor, material's high viscosity, spindle speed faster, agitator diameter is too large and so on.
1. Replace the reactor with the stent bearing
2. According to the reactor operating procedures to adjust the temperature, material viscosity can not be too high
3. Control the spindle speed in a certain range
4. Adjust the diameter and angle of the mixing blade
1. Generally because the reactor work instrument produces over-temperature, overpressure phenomenon, instrument failure, control is not strict.
Solution: check, repair control device, strictly enforce the operating procedures, while stopping other operations.
2. Improper operation such as improper proportion of raw materials; produce a severe reaction.
Solution: According to the operating method, take emergency pressure relief, in strict accordance with the operating procedures.
3. due to heat transfer or agitator performance is poor, resulting in side effects.
Solution: According to the actual experience to adjust, under normal circumstances, such as the thermometer shows running a temperature difference within a certain range. If the deviation is large, check the probe or conveyor. Increase the power of the stirrer, and provide the heat transfer effect of heating.
4. Reactor intake valve aging or intake pressure is too large.
Solution: close the total intake valve, maintenance.
