The influence of the number of grooves on the end face of a mechanical seal on the sealing performance:

The effect of the number of grooves on the end face of a mechanical seal on the performance of the seal is shown in Figure 3-18. With the increase of the number of grooves, the fluid film stiffness, opening force and upstream pumping volume of the mechanical seal pumped upstream of the spiral groove increase. Big. However, when the number of grooves is increased to a certain number, the gain of sealing performance parameters with the increase of the number of grooves is very small. It can be seen that if you consider both performance and economic factors, the number of grooves on the sealing end face is not the better. 110 mechanical seal
