同煤國電王坪綜合利用坑口電廠2×220MW級超高壓直接空冷機(jī)組，額定值659T/h的CFB鍋爐兩組。引風(fēng)機(jī)：6KV/2240KW×4；一次風(fēng)機(jī)：6KV/2240KW×4；二次風(fēng)機(jī)：6KV/1120KW×4，均采用液力耦合器調(diào)節(jié)風(fēng)機(jī)運(yùn)行轉(zhuǎn)速。
液力耦合器是一種利用液體介質(zhì)傳遞轉(zhuǎn)速的機(jī)械設(shè)備，其主動輸入軸端與原傳動機(jī)相聯(lián)結(jié)，從而輸出端與負(fù)載軸端聯(lián)結(jié)，通過調(diào)節(jié)液體介質(zhì)的壓力，使輸出軸的轉(zhuǎn)速得以改變。理想狀態(tài)下，當(dāng)壓力趨于無窮大時，輸出轉(zhuǎn)速與輸入轉(zhuǎn)速相等，相當(dāng)于剛性聯(lián)軸器。當(dāng)壓力減小時，輸出轉(zhuǎn)速相應(yīng)降低，連續(xù)改變介質(zhì)壓力，輸出轉(zhuǎn)速可以得到低于輸入轉(zhuǎn)速的無級調(diào)節(jié)。
液力偶合器的特點：
● 啟動：液力耦合器利用能耗轉(zhuǎn)差調(diào)節(jié)原理，起動時負(fù)載與電機(jī)主軸脫離，相當(dāng)于空載全壓起動。電機(jī)全速運(yùn)行后，通過調(diào)節(jié)液力耦合器工作腔內(nèi)的油量實現(xiàn)柔性連接，逐步升速。即液力耦合器不能實現(xiàn)軟啟動。
● 調(diào)速范圍：液力耦合器由于其輸出轉(zhuǎn)速低于輸入轉(zhuǎn)速，調(diào)速越深，損耗越大。故其調(diào)速范圍只能在20%以內(nèi)。
● 效率：液力耦合器是一種能耗型的機(jī)械調(diào)速裝置，輸出轉(zhuǎn)速低于輸入轉(zhuǎn)速。輸出轉(zhuǎn)速的降低，實際是輸出功率減小，調(diào)速越深（轉(zhuǎn)速越低），損耗越大。因此液力耦合器的平均效率在50%左右。
● 自動控制：液力耦合器不能對電機(jī)自動合理調(diào)速，存在很大的能源浪費(fèi)。
● 故障發(fā)生率：液力耦合器易發(fā)生故障，維修費(fèi)用高，并且影響生產(chǎn)。
針對使用液力耦合器自身特點及現(xiàn)場實際使用情況進(jìn)行分析，由于液力耦合器調(diào)節(jié)風(fēng)機(jī)運(yùn)行轉(zhuǎn)速存在著較大的能量損耗，為降低能耗以及提高發(fā)電機(jī)組自動化水平，我方經(jīng)過認(rèn)真分析計算，決定對上述使用液力耦合器調(diào)節(jié)轉(zhuǎn)速的風(fēng)機(jī)進(jìn)行變頻改造。
