熔體泵主要功能是將來(lái)自擠出機(jī)的高溫塑料熔體增壓、穩(wěn)壓后流量穩(wěn)定地送入擠出機(jī)頭。其穩(wěn)定熔料壓力、流量的能力優(yōu)于各種類型的擠出機(jī)。將它與單螺桿或同向雙螺桿擠出機(jī)串聯(lián)使用時(shí)，就使整條生產(chǎn)線的效益顯著增加。
The main function of high temperature melt pump is the plastic melt pressure, pressure will come from the extruder after stable flow into the extrusion die. The stability of melt pressure, flow capacity is better than all kinds of extrusion machine. It will be with single screw and twin - screw extruder used in series, makes the whole production line efficiency increased significantly.
應(yīng)用熔體泵的主要好處是：
The main advantage of using a melt pump is:
1.將擠出制品的尺寸公差降至小，使單位重量的物料制出更多的產(chǎn)品。在擠出制品的尺寸公差要求嚴(yán)格或制品的原料成本較昂貴時(shí)，使用熔體泵更為必要，更有價(jià)值。
Dimensional tolerances 1 extrusion to a minimum, so that the unit weight of the material for more products. In the dimension tolerance of extrusion products strict or product raw material cost is expensive, it is necessary to use the melt pump, more valuable.
2.將同向雙螺桿擠出機(jī)與熔體泵組合成混煉擠出造粒生產(chǎn)線，其混煉質(zhì)量和產(chǎn)量比單獨(dú)的雙螺桿造粒機(jī)組大幅提高。加工每公斤物料的能耗一般可降低百分之二十五左右。
2 co rotating twin screw extruder and melt pump into mixing extrusion granulation production line, the mixing quality and yield is greatly improved than the twin-screw granulator unit separate. Energy consumption per kilogram of materials processing can be reduced by about twenty-five percent.
3. 在原來(lái)是單螺桿或同向雙螺桿造粒擠出機(jī)上加裝熔體泵和管、板、膜等擠出機(jī)頭，可省掉造粒工序直接擠出制品。這種系統(tǒng)非常適合擠出制品的材料需要經(jīng)過(guò)共混改性的場(chǎng)合。該熔體泵系統(tǒng)除具有上述第2條優(yōu)點(diǎn)外，還通過(guò)簡(jiǎn)化擠出制品的生產(chǎn)工藝過(guò)程，縮短生產(chǎn)周期來(lái)實(shí)現(xiàn)節(jié)能。
3 in the original single screw or the same granulation twin-screw extruder with melt pump and pipe, plate, film extrusion die, granulation process can be saved directly extruded products. This system is very suitable for extrusion materials need to go through the modification. Besides the above mentioned second advantages of the melt pump system, also by simplifying the process of extrusion products, shorten production cycle to achieve energy efficiency.
4. 可以實(shí)現(xiàn)用多臺(tái)中小型擠出機(jī)同時(shí)向一臺(tái)熔體泵供料，熔料經(jīng)熔體泵增壓計(jì)量后供給機(jī)頭擠出大型制品（大口徑管材、寬幅板、膜等）。這種配置的生產(chǎn)線結(jié)構(gòu)緊湊，占地面積小；擠出制品的截面尺寸更精確且控制容易。
4 can be achieved using Taichung small extruder to a melt pump, melt the melt pump pressurized metering supply head extrusion of large products （large diameter pipe, wide plate, film etc.）。 The production line structure of this configuration is compact, small footprint; section size of extrusion products more precise and easy to control.
5.在單螺桿排氣擠出機(jī)上配置熔體泵，可使該系統(tǒng)的操作自如，性能優(yōu)異。在高機(jī)頭壓力和高產(chǎn)量下，擠出量可隨意調(diào)節(jié)而決無(wú)冒料情況出現(xiàn)。
5 in the single screw extruding machine configuration melt pump, can make the system operate freely, excellent performance. In the high head pressure and high yield, output can be adjusted and no overflow occurs.
