1、Good is good, but better carries it.精益求精，善益求善。DQYK-35BK型电动节流管汇控制箱使用说明书(新)-DQYK35BK型电动节流管汇控制箱使用说明书沈阳鑫榆林石油机械有限公司一、用途：电动节流管汇控制箱是液动节流管汇上的控制装置，它可以远程控制液动节流阀的开启和关闭，并在控制箱上可以显示出系统压力、立管压力、套管压力、两个液动节流阀阀位开度、3路泥浆泵泵冲计数与累计数。由此来维持井底压力，是成功的控制井涌、井喷，实施油气井压力控制技术所必要的设备。电动节流管汇控制箱所用电器部份具有防爆性能，仪表的数字显示清晰，且具有自检功能，电传感器性能可靠、灵敏

2、度高。二、主要技术指标：1）防爆电机：电源电压：380VAC（三相四线制）功率：0.75KW转速：1450r/min2）控制电源：220VAC（二线制）2、齿轮泵：排量：5L/min额定压力：6MPa3、蓄能器：额定压力：10MPa容积：10L4、压力变送器：1）系统压力：量程：010MPa2）立管压力：量程：040MPa3)套管压力：量程：040MPa所有变送器输出信号为：420mA5、电阀位变送器：量程：0180度输出信号：420mA6、数字显示控制仪表：显示位数：4位精度：0.5%FS1字7、输出扭矩：150Kgfm8、溢流阀调定为7.5MPa三、整机配备和工作原理：1、电动液控节流管汇

3、控制箱是由控制箱、压力变感器、电阀位变送器、电缆、液压管线等组成。控制箱由防爆仪表箱、防爆电机、齿轮泵、蓄能器、溢流阀、截止阀、三位四通换向阀、手动试压泵、油箱、液压元件、电器控制元件、数字显示控制仪表等组成。工作原理液压工作原理见图一电动节流管汇控制箱它集电动、液压于一体，将外部电能转换成液压能量去控制液动节流阀的开启和关闭。启动防爆电机带动齿轮泵，高压液压油经单向阀，进入蓄能器，蓄能器随着液压油进入量增多而压力增高，当压力升至设定值后电机停止，扳动三位四通换向阀可达到控制节流阀开、关的目的。速度调节阀作用是调节液压油流量，控制液动节流阀开或关的速度。溢流阀是当控制电路出现故障，即系统油压升

4、至超过设定最高压力电机仍未停止时，溢流阀打开，起着安全、保护作用。现场电源一旦中断，利用蓄能器所蓄的能量维持液动节流阀的“开”“关”一次。可利用“手动液压泵”（打印钢印标识号JK.00）来维持控制箱操作所需的油压，向蓄能器补充能量，以备使用。液压工作原理图（图一）说明：1、电动泵：电源电压：380VAC功率：0.75KW排量：5L/min2、最高压力：8MPa额定压力：6MPa蓄能器：10MPa、10LA1A5数字显示仪表B1B5变送器A1显示系统压力B1系统压力变送器A2显示套管压力B2套管压力变送器A3显示立管压力B3立管压力变送器A4显示节流阀1阀位开度B4节流阀1电阀位变

6、能器截止阀（该阀属于常开阀，出厂时打开状态）打开系统泄荷阀(该阀属于常闭阀，出厂时关闭状态)液压泵调试：将系统泄荷阀关闭，启动液压泵，此时系统升压，见盘面上系统压力数字显示仪，当压力达到7MPa时，电动泵自行停止工作；如系统油压降至5MPa时，电动泵可自行启动补充压力，保持其额定工作压力状态。溢流阀Y:出厂时已调至7.5MPa面板显示及外部联接图（图五）1、电源进线口2、传感器信号线入口3、液动节流阀1阀开接头（M221.5）4、液动节流阀1阀关接头（M221.5）5、液动节流阀2阀开接头（M221.5）6、液动节流阀2阀关接头（M221.5）7、数字显示仪：立管压力数字显示仪8、数字显示仪：

8、流管汇控制箱地线接好，以保护人身安全。将外接电源接好，动力电源为三相四线制的380VAC。控制电源为二线制的220VAC。防爆组合开关，插上插头后，旋转到“合”的位置，电源接通，旋转到“分”的位置，电源断开，敬请注意。6、电源正确连接后，按齿轮泵上方箭头方向，调试电机转向是否合适，如反向应立即停止，换向后再启动。7、打开泄荷阀，启动电动泵，空载运转，排除管路中的空气，连接节流阀液压管线。8、关闭泄荷阀，当系统油压升至设定值后，扳动三位四通换向阀手柄，使液动节流阀开、关两次，以排出液缸中空气。9、按标定的标识分别将立管压力变送器、套管压力变送器、液动节流阀1电阀位变送器、液动节流阀2电阀位变送器

9、、泵冲计数器等一一对应相接。检查各线路、管线连接无误后，将盘面“液压系统”开关旋至开位，启动电动泵，同时调整电阀位变送器的位置，当液动节流阀的实际位置与阀位开度显示仪表一致，将电阀位变送器的位置固定。油压升至7MPa时自动停泵，如系统油压的压力降至5MPa，电动泵可自动启动，保持系统压力。上述调整完毕后即可投入运行，根据钻井工艺的要求，操纵三位四通换向阀控制液动节流阀的开启和关闭。从而继续平衡钻井工艺所需井底回压。五、保养及维修：1、注意观察控制箱内外各油路有无泄漏的地方，观察各电缆线有无破损的地方，如有应马上关闭外部电源及时检修。2、经常观察“液位计”油面的高低，少则加油，每半年更换油箱内的

10、液压油一次，并同时清洗滤油器及油箱。3、每半年检查一次蓄能器充氮压力，预充氮气压为1.3MPa。4、故障指示：当此灯亮起时，代表电机出现故障。如：电机过载或电机实质性损坏等等，造成电机保护装置热过载继电器动作，从而使“电机故障”指示灯亮，此时应请电器专业人员进行维修。当故障解除后，电机保护装置热过载继电器自动复位，从而“电机故障”指示灯熄灭，系统恢复正常工作。六、DJFK6型角阀控制器（图六）DJFK6型角阀控制器是孔板式液动节流阀上的专用变送器，它将节流阀的开度转换成420mA电信号输送给数字显示仪以显示阀的开度。（图六）七、CS20D型压力变送器CS20D型压力变送器是为监测石油钻井作业中

11、立管、套管压力而配制的，它将立管、套管压力转换成420mA电信号输送给数字显示仪，以显示其实际压力。压力变送器与数字显示仪在出厂前已整机匹配调定，正常情况下不用调整。（图七）DQYK35BKTypeElectricThrottleManifoldControlBoxInstructionManualShenyangXinyulinPetroleumMachineryCo.,Ltd.ApplicationTheelectricthrottlemanifoldcontrolbox,designedforthecontroloverhydrodynamicthrottlemanifold,isuse
