Water ring vacuum pump is a type of vacuum pump that we can often use. We all know that its service performance is very good, but it does not rule out accidents. After a period of use, it is easy to have some unexpected problems. There are many factors that affect the normal operation of the vacuum pump, so the water temperature is one of them, whether the water temperature is too high or too low, it will have a certain impact on the operation of the vacuum pump. So, why on earth is this? Now let's have a detailed understanding of the reasons.
1. Too high water temperature will make the water evaporate, and the negative pressure condition will further aggravate the occurrence of this kind of vaporization and evaporation, making the pump body produce too much water vapor. In this way, when the water ring vacuum pump inhales too much water vapor, but seldom inhales outside, resulting in a very low vacuum degree of the system. There are two main reasons for the high water temperature, one is that the water supply temperature is too high, the other is that the water temperature rises in the working process.
2. Because the water temperature is related to the suction capacity, the working fluid temperature is high, and the air volume will decrease. With the increase of temperature, the evaporation capacity increases, occupying the original displacement, and the suction capacity decreases, which will prolong the vacuumizing time. In addition, under the vacuum condition, the evaporation capacity of the sealing liquid will increase with the increase of temperature, and the larger the percentage of the displacement, the situation that cannot be vacuumized will occur. As for the data involved too much, the evaporation capacity of sealing liquid under various vacuum degrees and the evaporation capacity under various temperatures are not the same, so it is impossible to give specific data. Only under certain vacuum degrees can the temperature change be reflected and the evaporation capacity change be caused. In use, it must be combined with temperature, and the superposition of two performance curves of vacuum degree and pump performance curve can be seen.
