油研變量泵系統(tǒng)的應(yīng)用　實(shí)現(xiàn)了注塑機(jī)液壓系統(tǒng)由閥控向泵控的轉(zhuǎn)變，使常規(guī)的節(jié)流調(diào)速系統(tǒng)轉(zhuǎn)變?yōu)楸壤{(diào)速系統(tǒng)，整機(jī)的控制性能指標(biāo)有了新的改善和提高。具體而言，比例變量泵系統(tǒng)除具有常規(guī)比例控制系統(tǒng)的優(yōu)點(diǎn)外，更具有如下優(yōu)點(diǎn)：
相同功率的機(jī)器，注射速度可提高25%以上，更適應(yīng)薄壁精密注射要求。由于普通PQ系統(tǒng)功率計(jì)算以保壓狀態(tài)為標(biāo)準(zhǔn)，比例變量泵系統(tǒng)在這一動(dòng)作時(shí)功率消耗很低，因而油泵排量可加大25%以上；
系統(tǒng)發(fā)熱降低，液壓元件使用壽命延長。比例變量系統(tǒng)幾乎無節(jié)流、溢流損失，系統(tǒng)運(yùn)行時(shí)發(fā)熱大大減少。不僅可節(jié)省冷卻水之消耗，低油溫使密封元件壽命大大提高；
能量消耗減少，系統(tǒng)效率提高；
可實(shí)現(xiàn)數(shù)控比例背壓的控制，塑化效果得到了改善；
液壓系統(tǒng)污染度水平降低，系統(tǒng)故障明顯減少，運(yùn)動(dòng)穩(wěn)定性大大提高，液壓油使用時(shí)間比常規(guī)系統(tǒng)延長3年以上。
比例變量泵系統(tǒng)具有良好的自適應(yīng)性，其輸出的壓力和流量能夠與負(fù)載需求相一致，解決了節(jié)流調(diào)速系統(tǒng)的流量不適應(yīng)和壓力不適應(yīng)問題，能量損耗大大減少，系統(tǒng)效率提高，節(jié)能效果十分明顯，與普通定量泵+PQ比例閥系統(tǒng)相比較，可節(jié)電25～45%。
