Plastic extrusion melt pump system characterization

　　Melt pump is usually used with a single or twin screw extruder in plastics processing , it can be further homogenization of the melt , pressure stability , material output pulseless , can improve the quality of products. This device is not only used the plastic melt granulation, mixing , can also be used for sheet extrusion , tubing, films and profiles. Works melt pump and the main structure of the gear pump hydraulic system similar . However, due to the special nature of plastics processing technology , material selection and structural design has its uniqueness . In the plastic processing , the melt is installed between the pump and the extruder head . This can be generated by fluctuations in the extrusion direction of the head and the downstream equipment and to isolate, irrespective of whether the pressure fluctuations occurring at the pump inlet , as long as the pump into the melt can be sufficiently filled with the cogging , it is able to stabilize the pressure delivery of materials to the head and flow , and to ensure that no fluctuations in the extrusion head , thereby improving the stability and accuracy of the system products . Meanwhile, the melt is a booster pump , voltage regulator , it can boost the function of the extruder metering section to move up the completion of the melt pump , thus avoiding the extruder head to work under high pressure the presence of power consumption, shearing force, friction violent materials stay a long time , and easily degradable and other shortcomings, the extrusion increased productivity , reduced wear extruder . Further , the system can increase a melt pump can be controlled to reduce the temperature of the melt , reducing energy consumption, the linear output . Throughout the extrusion system controls all process parameters by computer , can be plastic extrusion molding technology to a new level.
