1、Good is good, but better carries it.精益求精，善益求善。DQYK-35BK型電動節流管匯控制箱使用說明書(新)-DQYK35BK型電動節流管匯控制箱使用說明書沈陽鑫榆林石油機械有限公司一、用途：電動節流管匯控制箱是液動節流管匯上的控制裝置，它可以遠程控制液動節流閥的開啟和關閉，并在控制箱上可以顯示出系統壓力、立管壓力、套管壓力、兩個液動節流閥閥位開度、3路泥漿泵泵沖計數與累計數。由此來維持井底壓力，是成功的控制井涌、井噴，實施油氣井壓力控制技術所必要的設備。電動節流管匯控制箱所用電器部份具有防爆性能，儀表的數字顯示清晰，且具有自檢功能，電傳感器性能可靠、靈敏

2、度高。二、主要技術指標：1）防爆電機：電源電壓：380VAC（三相四線制）功率：0.75KW轉速：1450r/min2）控制電源：220VAC（二線制）2、齒輪泵：排量：5L/min額定壓力：6MPa3、蓄能器：額定壓力：10MPa容積：10L4、壓力變送器：1）系統壓力：量程：010MPa2）立管壓力：量程：040MPa3)套管壓力：量程：040MPa所有變送器輸出信號為：420mA5、電閥位變送器：量程：0180度輸出信號：420mA6、數字顯示控制儀表：顯示位數：4位精度：0.5%FS1字7、輸出扭矩：150Kgfm8、溢流閥調定為7.5MPa三、整機配備和工作原理：1、電動液控節流管匯

3、控制箱是由控制箱、壓力變感器、電閥位變送器、電纜、液壓管線等組成。控制箱由防爆儀表箱、防爆電機、齒輪泵、蓄能器、溢流閥、截止閥、三位四通換向閥、手動試壓泵、油箱、液壓元件、電器控制元件、數字顯示控制儀表等組成。工作原理液壓工作原理見圖一電動節流管匯控制箱它集電動、液壓于一體，將外部電能轉換成液壓能量去控制液動節流閥的開啟和關閉。啟動防爆電機帶動齒輪泵，高壓液壓油經單向閥，進入蓄能器，蓄能器隨著液壓油進入量增多而壓力增高，當壓力升至設定值后電機停止，扳動三位四通換向閥可達到控制節流閥開、關的目的。速度調節閥作用是調節液壓油流量，控制液動節流閥開或關的速度。溢流閥是當控制電路出現故障，即系統油壓升

4、至超過設定最高壓力電機仍未停止時，溢流閥打開，起著安全、保護作用。現場電源一旦中斷，利用蓄能器所蓄的能量維持液動節流閥的“開”“關”一次。可利用“手動液壓泵”（打印鋼印標識號JK.00）來維持控制箱操作所需的油壓，向蓄能器補充能量，以備使用。液壓工作原理圖（圖一）說明：1、電動泵：電源電壓：380VAC功率：0.75KW排量：5L/min2、最高壓力：8MPa額定壓力：6MPa蓄能器：10MPa、10LA1A5數字顯示儀表B1B5變送器A1顯示系統壓力B1系統壓力變送器A2顯示套管壓力B2套管壓力變送器A3顯示立管壓力B3立管壓力變送器A4顯示節流閥1閥位開度B4節流閥1電閥位變

6、能器截止閥（該閥屬于常開閥，出廠時打開狀態）打開系統泄荷閥(該閥屬于常閉閥，出廠時關閉狀態)液壓泵調試：將系統泄荷閥關閉，啟動液壓泵，此時系統升壓，見盤面上系統壓力數字顯示儀，當壓力達到7MPa時，電動泵自行停止工作；如系統油壓降至5MPa時，電動泵可自行啟動補充壓力，保持其額定工作壓力狀態。溢流閥Y:出廠時已調至7.5MPa面板顯示及外部聯接圖（圖五）1、電源進線口2、傳感器信號線入口3、液動節流閥1閥開接頭（M221.5）4、液動節流閥1閥關接頭（M221.5）5、液動節流閥2閥開接頭（M221.5）6、液動節流閥2閥關接頭（M221.5）7、數字顯示儀：立管壓力數字顯示儀8、數字顯示儀：

8、流管匯控制箱地線接好，以保護人身安全。將外接電源接好，動力電源為三相四線制的380VAC。控制電源為二線制的220VAC。防爆組合開關，插上插頭后，旋轉到“合”的位置，電源接通，旋轉到“分”的位置，電源斷開，敬請注意。6、電源正確連接后，按齒輪泵上方箭頭方向，調試電機轉向是否合適，如反向應立即停止，換向后再啟動。7、打開泄荷閥，啟動電動泵，空載運轉，排除管路中的空氣，連接節流閥液壓管線。8、關閉泄荷閥，當系統油壓升至設定值后，扳動三位四通換向閥手柄，使液動節流閥開、關兩次，以排出液缸中空氣。9、按標定的標識分別將立管壓力變送器、套管壓力變送器、液動節流閥1電閥位變送器、液動節流閥2電閥位變送器

9、、泵沖計數器等一一對應相接。檢查各線路、管線連接無誤后，將盤面“液壓系統”開關旋至開位，啟動電動泵，同時調整電閥位變送器的位置，當液動節流閥的實際位置與閥位開度顯示儀表一致，將電閥位變送器的位置固定。油壓升至7MPa時自動停泵，如系統油壓的壓力降至5MPa，電動泵可自動啟動，保持系統壓力。上述調整完畢后即可投入運行，根據鉆井工藝的要求，操縱三位四通換向閥控制液動節流閥的開啟和關閉。從而繼續平衡鉆井工藝所需井底回壓。五、保養及維修：1、注意觀察控制箱內外各油路有無泄漏的地方，觀察各電纜線有無破損的地方，如有應馬上關閉外部電源及時檢修。2、經常觀察“液位計”油面的高低，少則加油，每半年更換油箱內的

10、液壓油一次，并同時清洗濾油器及油箱。3、每半年檢查一次蓄能器充氮壓力，預充氮氣壓為1.3MPa。4、故障指示：當此燈亮起時，代表電機出現故障。如：電機過載或電機實質性損壞等等，造成電機保護裝置熱過載繼電器動作，從而使“電機故障”指示燈亮，此時應請電器專業人員進行維修。當故障解除后，電機保護裝置熱過載繼電器自動復位，從而“電機故障”指示燈熄滅，系統恢復正常工作。六、DJFK6型角閥控制器（圖六）DJFK6型角閥控制器是孔板式液動節流閥上的專用變送器，它將節流閥的開度轉換成420mA電信號輸送給數字顯示儀以顯示閥的開度。（圖六）七、CS20D型壓力變送器CS20D型壓力變送器是為監測石油鉆井作業中

11、立管、套管壓力而配制的，它將立管、套管壓力轉換成420mA電信號輸送給數字顯示儀，以顯示其實際壓力。壓力變送器與數字顯示儀在出廠前已整機匹配調定，正常情況下不用調整。（圖七）DQYK35BKTypeElectricThrottleManifoldControlBoxInstructionManualShenyangXinyulinPetroleumMachineryCo.,Ltd.ApplicationTheelectricthrottlemanifoldcontrolbox,designedforthecontroloverhydrodynamicthrottlemanifold,isuse
