The most commonly used vacuum technology in the chemical industry is vacuum degassing. This is because the chemical industry often needs to mix and stir certain liquid raw materials. During this process, air will be mixed into the raw materials and form bubbles. If left untreated, these bubbles will affect the quality of the final product. The vacuum degassing can solve it well. It involves vacuuming the sealed container containing the raw materials, using pressure to squeeze out the bubbles inside the materials. However, at the same time as vacuuming, it may also pump liquid raw materials into the vacuum pump, causing damage to the pump.
So, how should we protect the vacuum pump during this process? Let me share a case!
A customer is a glue manufacturer who needs to perform vacuum degassing when stirring liquid raw materials. During the stirring process, the raw materials will vaporize and be sucked into a vacuum pump. The trouble is that these gas will be compressed into liquid resin and curing agent! It caused damage to the internal seals of the vacuum pump and contamination of the pump oil.
It is obvious that in order to protect the vacuum pump, we must prevent the liquid or vaporized raw materials from being sucked into the vacuum pump. But ordinary intake filters are only used to filter powder particles and cannot achieve this. What should we do? In fact, the intake filter also includes a gas-liquid separator, which can separate the liquid in the gas, more accurately, re liquefy the vaporized liquid! In this way, the gas sucked into the pump is almost dry gas, so it will not damage the vacuum pump.
This customer purchased six more units after using the gas-liquid separator, and it can be imagined that the effect is good. Additionally, if the budget is sufficient, it is recommended to install a condensing device, which can liquefy and remove more water vapor before entering the pump chamber.
