The function of the vacuum pump is to absorb the air in the production environment, improve the vacuum degree of the environment, and reduce the air pressure in the environment. The suction phenomenon of the vacuum pump mainly occurs when the pump is malfunctioning or improperly operated. Once suction occurs, stop production immediately, because continued production will not only cause greater damage to the pump, but also pollute the production environment and cause serious production losses. Why is it said that back suction is related to the vacuum pump buffer bottle? Sometimes back suction occurs because the liquid in the production environment directly enters the pump body without an intermediate buffer part, so that the liquid will corrode the pump body, and the internal components of the water will cause corrosion.
When the liquid in the vacuum pump buffer bottle exceeds the mark, it must be dealt with as soon as possible, and the overflow may cause back suction. Some vacuum pumps do not even have this part of the design, and use a small-capacity tube to replace the buffer bottle. This method can be used if the content of water or other liquids in the vacuumed environment is not too much. Reverse suction does not necessarily cause serious problems. You need to observe further to see where the reverse suction is. If it does not enter the pipe or the filtrate bottle, there will be no major problems. When the vacuum pump is started here, it can return to its original position under the action of pressure. If these positions are exceeded, it may go to other positions of the pump when the pump is started again, affecting the operation of the pump. The function of the filtrate is to absorb water vapor or other components in the air. When the pump is sucked back and the liquid enters the filtrate, the filtrate must be replaced with a new one, because its absorption capacity may be affected, and it will filter the subsequent absorption of air. Function has an impact.
Some vacuum pumps have high power and can draw a relatively high degree of vacuum. When the operation is improper, serious suction will occur. Some vacuum pumps can be powered off in time when reverse suction occurs to prevent leakage or short circuit and burn out the motor. Some pumps do not have this function. You must pay special attention when using it. Generally, adding a buffer bottle can reduce the occurrence of suction, even if it occurs, it can be compensated in time. Therefore, it seems that the vacuum pump buffer bottle is very useful. Once the vacuum pump is damaged, the maintenance and replacement costs will not be too low. If adding a small buffer bottle can prevent this part of the expenditure, it is a very meaningful operation for the producer.
