● 關(guān)斷邏輯
整流器關(guān)斷           加藥泵關(guān)斷          海水泵關(guān)斷。
此邏輯順序適合于所有關(guān)斷方式。
b.聯(lián)鎖控制邏輯
聯(lián)鎖控制邏輯包括:
● 備用切換
海水泵、加藥泵均有備用設(shè)置,在啟動(dòng)或運(yùn)行過程中,如果運(yùn)行設(shè)備出現(xiàn)故障,則關(guān)斷運(yùn)行設(shè)備,同時(shí)自動(dòng)切換到備用設(shè)備。
● 時(shí)序邏輯聯(lián)鎖
各設(shè)備的啟停操作必須符合工藝要求的時(shí)序邏輯。
● 順序邏輯聯(lián)鎖
按啟動(dòng)邏輯和關(guān)斷邏輯,方可順序操作設(shè)備,如果違反順序,則操作命令不能執(zhí)行。
如:必須先開海水泵后,才能開啟整流器。反之則不能。
● 條件邏輯聯(lián)鎖
按啟動(dòng)邏輯和關(guān)斷邏輯,一些設(shè)備的啟動(dòng)或關(guān)斷必須滿足一定的條件,若條件不滿足,則操作命令不能執(zhí)行。
如:海水泵啟動(dòng)后,必須在流量、壓力、溫度條件滿足時(shí),方允許啟動(dòng)整流器。
