Screw vacuum pump in the process of use, due to the environment, manual operation and other reasons, will cause some damage to the screw vacuum pump. Tell you why the seal is not tight enough in use:
1. Microbial mud is less polluted and full of yellowing void, which harms the compensation effect of yellowing on the sealing performance, increases the friction damage of rotating and rotating rings, and affects the sealing performance. Operators can be required to conduct quarterly removal of screw vacuum pump inspection
2, the addition of machine chemicals will cause slow erosion of the screw vacuum pump seal ring, will cause the seal invalid, so in the application to the operation, should first ask the screw vacuum pump businessmen applicable medium
What is the reason of insufficient sealing degree of screw vacuum pump
3. The comprehensive action of toxotoxins, microbial mud, calcium ions and related organic chemicals often contained in the working fluid corrodes the metal parts of the machine seal itself, which will harm the sealing performance of the screw vacuum pump seal
4. During the filling process of the upstream and downstream catalyst carriers, most of the soot is removed according to brushing and other processes. However, with the increase of operation time and the corrosion of material cyclone, new smoke and dust will inevitably be generated. The dust in the screw vacuum pump can easily enter the sealing position of the mechanical seal, causing damage and requiring regular maintenance and cleaning
5, screw vacuum pump working fluid (containing calcium ions) and carbon dioxide in the raw materials reflect the transformation of calcium bicarbonate damaged the machine seal. This is inevitable, but it can be maintained regularly and avoided as much as possible
