What are the reasons for melt pumps not discharging properly?

Melt pumps are widely used in plastics, rubber precision extrusion field, used for melt conveying, pressurization, metering, is currently an important supporting equipment for rubber and plastic extrusion line. Melt pump daily operation, can not be discharged properly is a common failure of the extrusion melt pump. For the cause of the melt pump can not be discharged normally, with a variety of factors, Zhengzhou Bart melt pump manufacturers will be described in the following instructions.

extrusion melt pump

Caused by the pump melt gear pump for plastic extruder can not be discharged properly have the following factors:

1, the melt pump rotates in the opposite direction;

2, the melt pump suction or discharge valve closed;

3, the melt pump inlet material or pressure is too low;

4, the viscosity of the conveyed material is too high, the melt pump can not bite the material and so on.

Years of polymer melt pump production experience, Zhengzhou BATTE melt pump manufacturers to give the following troubleshooting measures or solutions:

1、Confirm whether the rotation direction of the melt pump is correct;

2, confirm whether the valve is closed;

3, check the valve status and pressure gauge values;

4, check the viscosity of the transported melt, when the melt pump is running at a low speed in proportion to the speed of the flow rate whether it appears, if there is a flow, the inflow is insufficient.

chemical melt pump

The above four measures are effective ways to solve the melt pump can not be discharged normally, is tested in practice. Zhengzhou BATTE melt pump manufacturers to provide special melt gear pump equipment including: polyester melt booster pumps, chemical fiber melt metering pumps, polyethylene melt gear pumps and so on.
