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 advantage of batte melt pump

　　1. Linear extrusion characteristics, facilitate upstream or downstream equipment coordination.Due to the gear pump leakage flow rate is less, the transmission capacity of the pump and rotating speed and a linear relationship with basic gear pump speed change, its flow can exactly know, due to the upstream or downstream equipment can be determined with the work of gear pump synchronous speed, using the gear pump inlet and outlet to collect information such as pressure, temperature, realize the whole extrusion process on-line monitoring and feedback control.

　　2. To increase production, reduce energy consumption, low temperature extrusion, prolonging the life of the machine.Due to polymer melt pump extruder installed, put on the reducing function is transferred to the gear pump extruder, the extruding machine can work under low pressure low temperature condition, leakage flow rate reduce greatly, increase production.Than gear pump extruder are more likely to effectively create head pressure, and can reduce the back pressure of extruder, the screw on the axial force drops, prolong service life.

　　3. Can realize the stable extrusion, improve the product dimensional accuracy, reduce rejection rate.In extrusion process, the material and capacity is uneven, machine barrel, and the nose temperature fluctuations, the screw rotation speed pulsation phenomenon is inevitable.Using melt gear pump can eliminate system error of feeding, can greatly abate the upstream volatility of technology transfer, quickly into the stable working status, improve the product dimensional accuracy, reduce scrap rate.
