力士樂柱塞泵過濾裝置是由多層重疊過濾網(wǎng)板和過濾框組成，網(wǎng)板孔由電腦打孔,，孔密小均勻,，這可保證每層過濾網(wǎng)板上的濾材壓力均勻，使過濾精度優(yōu),，原液體經(jīng)過加壓進(jìn)入筒體內(nèi),，從過濾框四周孔進(jìn)入，再經(jīng)網(wǎng)板上的過濾介質(zhì)從網(wǎng)板中心多個(gè)小孔出來,，合格液體排出,。本機(jī)濾材可選用（聚丙烯濾膜、增強(qiáng)型濾膜,、濾紙,、濾布，專用脫碳過濾膜）等,，可根據(jù)用戶要求選用合適的濾材,。本機(jī)的特點(diǎn)：流量大、速度快,、存活性碳多,、占用空間小,，過濾面積大、效率高,、過濾精度高,，操作方便等。合成氨裝置,。因?yàn)楹铣砂痹蛢艋椒ú煌?，其工藝流程不同，所需閥門的技術(shù)機(jī)能也不同,。目前,，海內(nèi)合成氨裝置主要需用閘閥、截止閥,、止回閥,、疏水閥、蝶閥,、球閥,、隔膜閥、調(diào)節(jié)閥,、針型閥,、安全閥、高溫低溫閥,。其中,，截止閥占裝置用閥總數(shù)據(jù)的53.4%,閘閥占25.1%,疏水閥占7.7%,安全閥占2.4%,調(diào)節(jié)閥和離低溫閥及其它占11.4%.乙烯裝置,乙烯裝置是石油化工的龍頭裝置,其需用閥門種類繁多。閘閥,、截止閥,、止回閥、升降桿式球閥占大多數(shù),，其中閘閥需居首,。
