齒輪泵技術(shù)

1.能實(shí)現(xiàn)穩(wěn)定擠出，提高擠出制品尺寸精度，降低廢品率。在擠出過程中，物料加料量的不均勻、機(jī)筒和機(jī)頭溫度的波動(dòng)、螺桿轉(zhuǎn)速的脈動(dòng)等現(xiàn)象是難以避免的。使用熔體齒輪泵可消除加料系統(tǒng)的加料誤差，可大幅度減弱上游工藝傳遞的波動(dòng)，快速的進(jìn)入穩(wěn)定的工作狀態(tài)，提高擠出制品尺寸精度，降低廢品率。
2.提高產(chǎn)量，降低能耗，實(shí)現(xiàn)低溫?cái)D出，延長機(jī)器的壽命。由于擠出機(jī)安裝了聚合物熔體泵，把擠出機(jī)的減壓功能轉(zhuǎn)移到齒輪泵上完成，擠出機(jī)可在低壓低溫狀態(tài)下工作，漏流量大大減少，產(chǎn)量提高。齒輪泵比擠出機(jī)更易有效的建立機(jī)頭壓力，并可降低擠出機(jī)的背壓，使螺桿承受的軸向力下降，延長使用壽命。
3.具有線性擠出特性，便于上、下游設(shè)備協(xié)調(diào)工作。由于齒輪泵漏流量較少，泵的輸送能力與轉(zhuǎn)速基本成線性關(guān)系，齒輪泵轉(zhuǎn)速改變后，其流量能確切的知道，由于可以確定上、下游設(shè)備與齒輪泵同步的工作速度，利用齒輪泵入口、出口處采集的壓力、溫度等信息資料，實(shí)現(xiàn)整個(gè)擠出過程全程在線監(jiān)控與反饋控制。
4.可以實(shí)現(xiàn)用多臺中小型擠出機(jī)同時(shí)向一臺熔體泵供料，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、寬幅版、膜等）。這種配置的生產(chǎn)線結(jié)構(gòu)緊湊，占地面積?。粩D出制品的截面尺寸更精準(zhǔn)且控制容易。
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)而決無冒料情況出現(xiàn)。
高粘度泵的工業(yè)應(yīng)用范圍
齒輪結(jié)構(gòu)高粘度泵的齒輪常見的有直齒、斜齒、人字齒、螺旋齒，齒廓主要有漸開線和圓弧型式。通常小型齒輪泵多采用漸開線直齒輪，高溫齒輪泵常采用變位齒輪，輸送高粘度、高壓聚合物熔體的熔體泵多采用漸開線斜齒輪。齒輪與軸制成一體，其剛性及可靠性高于齒輪與軸單獨(dú)制造的齒輪泵。高粘度泵是根據(jù)石油、化工、涂料、油脂、醫(yī)藥、染料、食品等行業(yè)的需求，研制開發(fā)的新型容積式泵，由于該產(chǎn)品可選用不同的材質(zhì)和其獨(dú)特的結(jié)構(gòu)，因此廣泛應(yīng)用于不同性質(zhì)、不同粘度的介質(zhì)輸送。適用介質(zhì)溫度：-10℃ - 200℃（NYP0.78和NYP2.3的適用溫度為-10℃ - 80℃）。
