Characteristics of the structural design of bushings for melt gear pumps
The sleeve for melt gear pump is characterized in that a flow-guiding groove for melt infiltration is provided on the inner bore wall of the sleeve, and a reflux groove is provided on one side wall and the outer side wall of the sleeve. The flow-guiding groove, the groove opening on the cavity side of the melt gear pump is the big end, and the big end is deeper and wider than the small end of the groove opening near the cover side. The flow-conducting groove extends from the large end to the small end with a certain degree of curvature, and the groove opening at the large end gradually extends from a deeper and wider groove opening to a shallower and narrower groove opening at the small end.
One end of the reflux groove is close to the small end of the reflux groove but not connected through, the reflux groove extends from one side wall of the sleeve to the outer side wall of the sleeve. Shaft sleeve pair symmetrically set up corresponds to the active shaft and the slave shaft, two shaft sleeve return groove corresponds to set up, the return groove forms the return hole.
Using the structure of the sleeve set in the pump body of the active shaft and the slave shaft, sleeve and shaft to do the relative rotation movement, a small part of the melt in the pump body through the large end of the guide groove infiltration into the sleeve inside the wall to play a good lubrication, infiltration into the guide groove melt from the small end of the guide groove outflow into the reflux groove in the same vicinity of the part of the self-lubrication of the melt in the pump inside and outside of the role of the pressure difference back to the pump cavity, to realize a self-lubricating cycle, to achieve a self-lubricating cycle, to achieve a self-lubricating cycle. Realize a self-lubricating cycle, can reduce the wear of the sleeve and shaft, to maintain the long-term stable operation of the melt gear pump.
