Factors affecting sealing effect of water ring vacuum pump

When we use the water ring vacuum pump, sometimes the sealing effect will decline. How can we deal with this situation? To solve the problem, we first need to understand the reasons for this situation. The following article explains the factors that affect the sealing effect of water ring vacuum pump in detail. Let's take a look at them.

1. The biological slime of the water ring vacuum pump fills the gap of the tension spring day by day, which affects the compensation effect of the tension spring in the seal, also intensifies the wear of the dynamic and static ring conflict pairs, and affects the sealing effect of the auxiliary sealing ring. The presentation of this situation requires us to carry out the vacuum pump cleaning regularly.

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

3. The corrosion of the metal parts of the whole mechanical seal body caused by the induction effect of the isooxybacteria, biological slime, calcium ions and related chemicals contained in the working fluid seriously affects the sealing effect and application time of the mechanical seal.

4. Although most of the dust in the upstream adsorbent is removed through selection and other steps during loading, with the increase of operation time and the flushing of medium air flow, new dust will be generated more or less, and the dust entering the water ring vacuum pump may enter the sealing position of the machine seal at any time, causing damage to it, so we need to carry out regular maintenance and cleaning.

5. The slow corrosion of the added relevant chemicals to the sealing ring of the water ring vacuum pump will cause the sealing failure. In fact, prior to the selection of chemical reagents for use, the experienced manufacturers will select chemicals with less corrosiveness or even without.
