聚乙烯塑料生產(chǎn)中，擠壓造粒設(shè)備的控制系統(tǒng)是保障設(shè)備正常運行和產(chǎn)品質(zhì)量的關(guān)鍵。各生產(chǎn)線的設(shè)備中大多是采用純硬件搭接的控制系統(tǒng)或配套DCS控制系統(tǒng)。依據(jù)擠壓造粒設(shè)備的控制特點，在近期新建國產(chǎn)擠壓造粒設(shè)備中，采用PLC控制系統(tǒng)代替了原來由繼電器搭接的陳舊古老的控制系統(tǒng)。改造后的PLC控制系統(tǒng)具有功能強勁、性能穩(wěn)定、易于維護等優(yōu)點。

改造前，由于進料的不穩(wěn)定性及產(chǎn)品牌號改變的經(jīng)常性，手動操作很難使產(chǎn)品達到較理想的水平，且經(jīng)常出現(xiàn)堵料、防爆膜由于壓力過高損壞及其它機械故障等。采用PLC控制系統(tǒng)控制后，改善了設(shè)備運行的可靠性及連續(xù)穩(wěn)定性，使產(chǎn)品質(zhì)量達到較高水平。
