選用的變頻器是移相多重化的中壓變頻器,主回路上沒有發生過故障,其可靠性還是比較滿意的。雖然在運行時曾發生跳車,但其原因是外線路失電引起的。控制回路上由于濕度高而有過幾次故障。采取的措施是變頻器室內加裝除濕設備,平時加強對設備的保養。所應用的節能產品與非節能產品相比,降耗方面的表現。多功能控制閥使用現場。
節能前后的能耗比較主要從兩方面進行說明,,獨立的節能設備,例如催化煙氣輪機節能12000kW,每年節約價值7000萬元以上。第二,設備節能改造后與改造前的能耗對比。2010年對全公司機泵、空冷、鼓引風機的運行參數與設計值、實際運行參數進行了統計估算,篩選出了64個位號的轉動設備有較好的節能潛力。邀請中國石油大學、撫順石油學院對這些設備進行了詳細核算和標定,并分幾批對機泵進行了改造。下一階段將繼續深化轉動設備節能改造,目前正在實施的節能項目主要有鍋爐鼓、引風機增加液力偶合器的改造,硫磺焚燒爐風機增加磁力調速器的改造,部分涼水塔風機、空冷風機增加永磁調速器的改造及新上技措項目配套電動機采用高效節能變頻電動機等。預計在2011年公司在設備節能方面將會提高一個大的臺階,收效也將會是非常顯著的。
在實際工程設計與應用中,為了保證大負荷時風機或水泵系統滿足輸出要求,通常需要按系統的大輸出能力配備風機水泵系統,而真正使用中,絕大多數情況下并非需要系統在滿負荷下使用,而是根據負載的實際需要,通過流量控制元件如閥門或風門擋板等,實現流量和壓力控制,以滿足生產過程的需要。
