Reasons for insufficient sealing of screw vacuum pump
When people use screw vacuum pump, some of them will have the actual sealing effect reduced. They are willing to solve the problem. People must first understand the reasons for this situation. The following will give you a detailed introduction.
1. Microbial sludge pollution is less, full of yellowing space, which endangers the compensation effect of yellowing on the sealing performance, increases the damage of friction pairs of dynamic and static rings, and endangers the sealing performance. Auxiliary sealing ring. Effect, the emergence of this situation, requires people to remove the screw vacuum pump every quarter.
2. The slow erosion of the sealing ring of screw vacuum pump caused by the addition of organic chemicals will lead to ineffective sealing. I think that before the application of chemicals, the manufacturers with working experience choose the less corrosive or even organic chemicals.
3. The working fluid often contains toxic bacteria, microbial mud, calcium ions and related organic chemicals, which erode all the metal parts of the machine seal, seriously endangering the sealing performance of the screw vacuum pump. Actual effect and application time.
4. During the filling process of upstream and downstream catalyst carriers, most of the soot will be removed according to the brushing process, but with the increase of operation time and the corrosion of material whirlwind, new smoke and dust will inevitably be generated. The dust in the screw vacuum pump enters the sealing position of the mechanical seal anytime and anywhere, causing damage, which requires quarterly maintenance and cleaning.
5. The working fluid (containing calcium ions) of screw vacuum pump and carbon dioxide in reducing materials reflect that the converted calcium bicarbonate damages the machine seal. This is inevitable, but people can do quarterly maintenance. Try to avoid problems in this line.
