Today we will explain some common troubleshooting methods（hot melter）, which can be easily solved by ourselves.
1. Small glue flow
The general reasons are:
①The amount of glue in the melting tank is insufficient;
②The filter inside the melting tank is clogged, causing poor glue suction;
③Failure of the return valve;
④The viscosity of the glue is too high or too low;
⑤The gear pump is internally worn and internal pressure is leaking.
① Heat and melt the glue in the melting tank to a reasonable position;
②Clean the filter screen of the melting tank to remove the blockage;
③Check whether the sealing ring of the return valve is damaged, whether the valve seat and valve body are worn, if there is wear, it needs to be replaced;
④Set the appropriate temperature of the glue tank to make the hot melt glue be used in the best condition;
⑤As a result of insufficient wear resistance of gears, shafts, and pump bodies, it may cause wear and tear. It is necessary to replace corresponding parts or replace the entire gear pump.
