How much do you know about screw seals in melt transfer pumps?
Seal life is the key to measuring the operating cycle of melt transfer pumps. Ensuring the long-term operation of melt transfer pumps is extremely important for the stability of polyester production. Packing seals are widely used in high viscosity melt transfer gear pumps due to their simple structure, low price and good reliability. However, due to the seal structure designed by different manufacturers and the use of different situations, the effect and service life of the packing seal varies greatly.
In recent years, the domestic manufacturers of high viscosity melt transfer gear pumps, are widely used in their products spiral seal and packing seal combination seal type, the use of good results. Screw seal is a kind of non-contact hydrodynamic seal, is a kind of relying on the shaft surface or / and the shell opened on the spiral groove on the viscous liquid pumping effect, the pressure to send out the viscous fluid so as to prevent the leakage of the sealed medium sealing device, mainly including three structural types: screw, screw sleeve and labyrinth type.
The main characteristics of the screw seal is no wear and tear at work, long life; can be used for dust-containing fluid media, especially containing abrasive particles and other harsh conditions of the media seal; the correct design of the seal, you can achieve zero leakage. Manufacturers in the high viscosity melt transfer pump, the more used is the screw sleeve structure. When the high viscosity melt transfer pump is working, it relies on the screw sleeve to achieve the function of sealing, and it relies on the packing seal to seal when it is stopped.
