Batte melt pump is on the production line

　　Batte Mechanical Zhengzhou Co.,Ltd.(Tel: +86 371 67991755 / 67992755 Web site: www.battemachinery.com) is a professional manufacturer of Melt pumps,Loss-in-weight Feeder,Screen changer. The main products are Melt pump,Feeder machine,Screen changer and gear pumps,metering pumps. Batte has accumulated abundant experience on the application technique of melt pumps since we manufacture pumps professionally. Recently according to the development trend of melt pumps application all over the world, especially in the field of precise plastic extrusion, we have done extensive research on the pump operation performance, practical function, equipment structure and control technology and achieved regular achievements.

　　The melt pump is on the production line

　　Melt pump is equal to the rotation of the barrier, it can be effective shielding, attenuation of inlet flow rate fluctuations caused by pressure changes, of course not completely shielding melt pump inlet influence on discharging mouth, through the test we found it could block more than 80% of the pressure fluctuation, that is to say, when the inlet pressure fluctuate in the range 1 MPa, discharging mouth pressure will be within the scope of 0.2 MPa (+ / - 0.1 MPa).Such shielding effect can solve single screw extruder for screw wear and add back material, scrap, add the filling material and the material bulk density changes caused by pressure fluctuations, could control the change of the size of products in a smaller range.

　　For some requiring high dimensional accuracy, the effect may not meet the requirements, we introduce the melt pump pressure closed loop control system, can adjust the speed of extruder closed loop to adjust the melt pump inlet pressure, reduce the inlet pressure range, control the discharging mouth of the pressure fluctuations in a very small range, relative to improve dimensional stability of the product, the axial size error control in the ideal range.
