Factors Influencing Sealing Effect of Water Ring Vacuum Pump

When we use water ring vacuum pump, sometimes the sealing effect will decrease. How can we deal with this situation? To solve the problem, we first need to understand the reasons for this situation.

1. The biological slime of water ring vacuum pump fills the gap of tension spring over time, which affects the compensation effect of tension spring in sealing, and also aggravates the wear of dynamic and static ring conflict pairs, which affects the sealing effect of auxiliary sealing ring. The appearance of this situation requires us to regularly arrange the vacuum pump.

2. It is inevitable that the working fluid of water ring vacuum pump (containing calcium ions) and the calcium carbonate produced by the reaction of carbon dioxide in the compacted medium will damage the mechanical seal, but we can carry out regular protection to minimize this problem.

3. The inductive effect of the isoaerobic bacteria, biological clay, calcium ions and the related chemicals in the working fluid on the corrosion of the metal parts of the whole mechanical seal body seriously affects the sealing effect and operation time of the mechanical seal.

4. Upstream adsorbent removes most of the dust through selection and other steps during loading, but with the increase of operation time and the erosion of medium airflow, new dust will always be produced more or less, and the dust entering the water ring vacuum pump may enter the sealing part of the machine at any time, causing damage to it, so it is needed. We maintain and clean regularly.

5. The slow corrosion of the sealing ring of water ring vacuum pump caused by the increase of related chemicals will lead to seal failure. In fact, before the selection of chemical reagents for use, experienced manufacturers will choose chemicals that are less corrosive or even not.
