按“程序啟動(dòng)”按鈕,啟動(dòng)壓濾機(jī)開(kāi)始卸料,高壓卸荷閥將油缸內(nèi)的高壓卸掉,以防止壓緊板松開(kāi)時(shí)液壓系統(tǒng)受沖擊。
a.高壓泄荷時(shí)間由 PLC 控制,當(dāng)延時(shí)時(shí)間達(dá)到后,壓濾機(jī)自動(dòng)轉(zhuǎn)入壓緊板松開(kāi)狀態(tài)。
b.  松開(kāi):油泵電機(jī)啟動(dòng),松開(kāi)閥得電,液壓站往油缸前腔供油,活塞桿帶動(dòng)壓緊板后退,濾室被打開(kāi),開(kāi)始卸料,當(dāng)壓緊板接觸到松開(kāi)限位開(kāi)關(guān)、后,壓濾機(jī)自動(dòng)停止
c.  壓緊:油泵電機(jī)運(yùn)轉(zhuǎn),壓緊電磁閥得電,液壓站往油缸高壓腔供油,活塞桿帶動(dòng)壓緊板前進(jìn),從而推動(dòng)濾板執(zhí)行壓緊動(dòng)作,當(dāng)濾板與止推板相接觸時(shí),液壓系統(tǒng)壓力上升,當(dāng)達(dá)到設(shè)定壓力上限值時(shí)壓濾機(jī)自動(dòng)轉(zhuǎn)入保壓狀態(tài)。
d.  補(bǔ)壓:由于泄漏等原因會(huì)使液壓系統(tǒng)壓力逐漸下降,當(dāng)其下降到壓力下限值時(shí),壓濾機(jī)油泵電機(jī)自動(dòng)啟動(dòng),壓緊補(bǔ)壓,使壓力表恢復(fù)上限值。 1.3.系統(tǒng)需要分析:該應(yīng)用旨在保證自動(dòng)壓濾機(jī)的可靠工作,西門(mén)子LOGO!提供了可顯示以及設(shè)定定時(shí)器,計(jì)數(shù)器等當(dāng)前值,這方面甚至超越普通PLC的功能。 而相比繼電器電路,顯得接線(xiàn)方便,帶載能力強(qiáng),以及縮減電氣柜安裝空間。 提升了壓濾機(jī)各部件品牌知名度。 三、應(yīng)用的設(shè)計(jì)與實(shí)現(xiàn) 電氣控制原理圖說(shuō)明(包括硬件配置以及安裝圖,如采用CAD繪制圖請(qǐng)全部使用黑色線(xiàn)條,不接受彩色線(xiàn)條) 圖3.主電路控制圖

This problem can be solved by using the left alignment. Four 8-ton steam boilers are designed and installed in the boiler room of Dingji mine of Huainan Mining Group. At present, two dzl8-1.25-aii assembled boilers produced by Wuhu Jinding Boiler Co., Ltd. are installed. Hwb-2002 distributed control system of our company is selected for thermal control. In addition, the boiler room is also equipped with two feed pumps, three boiler feed pumps and a set of deaeration device.



2、 System composition

The system adopts a two-level distributed computer distributed control system composed of PLC and industrial computer to detect, display, control, protect, alarm and manage the operation process of pressure fan. The field control station
