More than one third of the gear transmission noise of the melt gear pump comes from burrs and bumps, which is also a problem that is difficult to eradicate. Some manufacturers of melt gear pump engage a pair of gears on the noise checking machine before assembling the gear box to remove burrs and bumps, which is a very passive method. Butt melt gear pump manufacturers think that the following measures are more reasonable:
1. After cutting, all of them will be transported by the station device.
2, gear shaft parts, gear teeth immediately after the plastic tube and then transferred to the next process, and with plastic delivery.
3. Cyanide parts are treated by liquid sand blasting after heat treatment.
4, cyanide gear honing process.
