Specific Method for Reducing Axial Clearance Leakage of Melt

　　During the long-term use of the melt gear pump, leakage will occur, which seriously affects its production operation. For the leakage of the melt gear pump, it mainly exists in the leakage of the axial clearance. How to effectively reduce the leakage of the axial clearance of the gear pump is the primary premise to ensure the efficient production and operation of the melt gear pump. Butt Melt Gear Pump Manufacturer gives the following methods and measures.

　　Floating sleeve can be used to reduce the axial clearance of melt pump. To reduce the internal leakage, it is necessary to ensure the reasonable axial clearance of the melt gear pump. The structure sketch of the floating axle sleeve is shown in Fig. 1. Under the action of spring force, the right end of the floating axle sleeve can be closely attached to the end face of the gear to reduce the axial clearance and thus reduce the axial leakage. Another advantage of the structure is that it can automatically compensate the axial clearance and prolong the service life of the pump.
