The function of the grooves in the cover plates on both sides of the impeller
Thread Content
As the title suggests, grooves are cut into the cover plates on both sides of the impeller – what is the purpose of this? Is it to balance the axial force? If so, how is it balanced? If not, what is the purpose?
Does it balance the pressure difference before and after leaf fall? study*
Evenly distributed; seen for the first time. Maybe it’s what was mentioned upstairs – an auxiliary processing groove
Could it be a hydrodynamic pressure groove, like the one found on the seal ring of clone C8BKC?
The location of the grooves must meet certain requirements regarding the gap between the pump body and the pump cover. The grooves function like small impellers, providing a certain pumping effect that helps to reduce the backflow of high pressure from the outlet to the inlet
Thrust ball bearings should be used for the bearings, and the speed of this pump should not be high.
Yes, two sets of thrust ball bearings are installed on the drive side. The motor’s speed at level 6 is 970 revolutions per minute
The axial force is borne by the thrust ball bearing
