  1. 调整  Adjustment

整体式电装的电气箱盖上,设置两只旋钮分别为现场远控旋钮和开关旋钮。用于切换工作方式及现场的开、关、停操作。通过箱盖上的视窗孔,可以看到开度指示盘上三只发光二极管,其中黄灯亮表示电源正常,红灯亮表示行程开到位,绿灯亮表示行程关到位。整体式电动装置与阀门组装后,应对电气控制部分,力矩控制器,行程控制器,开度机构分别调整方可使用。具体调整如下:
On the cover of the electrical compartment of integrated actuators,two knobs are provided respectively for local/remote and open/close to use for the changing of operating modes and operations of opening,closing and stopping.Looking into the window on the cover,three LED can be seen on the position indicating dial.Among them,yellow lamp lighting indicates that the power supply is normal;red lamp lighting indicates that the opening  course is finished;and the green lamp lighting indicates that the closing course is finished.After the integrated electric actuators are assembled with the valves,only the electrical control compartment,torque limit mechanism,travel limit mechanism and position indicating mechanism has been properly adjusted,may the assembly be put into operation,Specific adjustment is shown as following;

  1. 检查电源

打开防爆接线盒接入动力线。接通电源,如果开度指示牌上黄色发光二极管不亮,则说明电源缺相(可能出现电源缺相,黄色发光二极管仍然亮的情况,但这时电动装置被锁住,不能进行开关操作)。应查明缺相原因,做适当处理。当接通电源黄色发光二极管亮了即可进行调试操作。
Check power supply
Open the cover of the flameproof terminal box and wire in it with power supply.If the yellow LED on indicating dial does not light ,it indicates the absence of phase.(Sometimes the absence of phase occurs but the yellow LED does still light normally.In such case,the actuator is locked and can not run.)The failure shall be found out and properly handled.When the power supply is turned on and the yellow LED lights,the actuator can be put into operation at once.

  1. 力矩控制器、行程控制器、开度机构的调整

拆下电气安装板螺丝,行程上下限位、力矩及开度机构的调整与普通型产品相同。调整完以后旋上安装螺丝,合上电气箱盖。至此,整体电动装置可以进行现场操作了。
Adjustment of torque limiter,travel limiter and position indicating mechanism Remove screws on electrical installation board,adjustment of travel limiter,torque limiter and position indicating mechanism is the same of normal type product.After the adjustment,tighten the fixing screws,put the cover on the electric compartment and fix it.Thus,the integrated electric actuators can be put into local operation.

  1. 力矩控制器的调整 力矩控制器的结构见图11.力矩控制器在出厂前已根据订货要求整定好并填在产品证明书(如用户未指定,通常开向整定在公称值上,关向为公称值的0.7),一般不允许再调整,若一定要调的话,必须十分谨慎,可参考产品证明书上的力矩曲线,查找对应刻度值,进行调整。方法如下:松开该方向的螺钉,将调整臂调到对应的刻度值,再坚固螺钉即可。决不能盲目高大,否则关严后可能打不开,如果超出力矩机构的控制范围将烧毁电机。

  1. Adjustment of torque mechanism

Structure of torque mechanism refer to Fig.11.Torque mechanism has been preset according to customer’s order and the numerical value of torque is filled in the certificate so it need not be reset usually.(If the customer has not specified,the set torque value for opening is generally the nominal value,and that for closing is 0.7 time of the nominal)If rated torque value needs resetting,refer to torque curve in the certificate and check corresponding scale.Adjust as following:Loosen screw,set the handle to corresponding scale and then fix screw.The setting is by no mean able to increase the value random,or the valve will not be able to open after seating,and the motor may be destroyed if the set value oversteps the control range.

  1. 行程控制器的调整 Adjustment of travel limit.

行程控制器的结构见图12. The structure of travel limit refer to Fig.12

  1. 阀门“全关|”位置的调整

①将手电动切换手柄按箭头方向推,用手动将阀门“全关”,再从这个位置稍退回一点。
②用螺丝刀压下顶轴,并转90̊可卡住为止。
③按关向箭头旋转“关向”调整轴,直到转动柱上的小凸台方向与两旁箭头方向基本一致为止。
④旋回顶轴,使之复位。
Adjustment of “Seating”
Pull the lever of hand/auto exchanger direction;Operate the valve to seating by hand wheel and then retreat a little from seating position.
Press top axis down by screwdriver and rotate and rotate the axis a quarter circle to be clamped.
Rotate closing regulating axis following closing arrow until the project bar on roller and arrows on both side are basically in same direction.
Return top axis to original position.

  1. 阀门“全开”位置的调整

①在阀门“全关”位置调好的基础上,手动或电动将阀门开到“全开”位置之前停下(建议开到全行程的95%左右)。
②用螺丝刀压下顶轴,并转90̊ 可卡住为止。
③按开向箭头旋转“开向”调整轴,直到转动柱上的小凸台方向与两旁箭头方向基本一致为止。
④旋回顶轴,使之复位。
Adjustment of “complete open”
Operate the valve from seated position to open by hand wheel or electric operating and stop before the valve is complete open(operation of 95% stroke).
Press top axis down by screwdriver and rotate the axis a quarter circle to be clamped.
Rotate opening regulating axis following opening arrow until the project bar on roller and arrows on both side are basically in the same direction.
Return top axis to original position.

  1. 中间位置的调整

中1和中2两个中间位置作为特殊规格供货,其标号图中未画出。用户可以根据需要用于开向或关向的中间位置,或用于增加开、关向的触点数。这时调整轴的旋转方向视中1、中2是用于开向还是关向定,若用于开向则与开向调整轴的旋向一致,若用于关向则与关向调整轴的旋向一致。
Adjustment of medium positions
MID1 and MID2 are supplied as special order.Their codes have not been indicated in the Fig.Customers can apply MID1 and MID2 to medium positions in opening course or closing course,or to increase the number of contacts if need be,when adjusting,the rotation of regulating axis depends on whether MID1 or MID2 is used for opening or closing.If used for opening,it will rotate in the same direction in which regulating axis for opening rotates,if used for closing,it will rotate in the same direction in which regulating axis for closing rotates.
行程控制器全部调好后,需电动试运转,控制器控制的整个行程应符合要求,否则需要重新进一步调整。
在行程控制器的调整过程中,如果出现调过头或者还没有开始调转柱已处于动作状态(即转动柱上小凸台方向与两旁箭头基本一致),这时需反方向旋转调整轴,直到恢复动作前状态,再按箭头方向重新调。
When the setting of travel limit is finished,the actuator need to be put into trial electric operation to check if the whole travel of the limit mechanism meets with the requirements,or it should be set once more.During the setting of travel limit,if it is overstepped or the roller acts before setting(i.e.raised part on roller is consistent with the arrows on both sides basically)it is necessary to rotate the regulating axis reversely till it recovers the status before acting.Then reset it according to the arrow direction.

  1. 开度机构的调整 Adjustment of position indicator

开度机构结构见图13,调整方法如下:Structure of position indication refer Fig.13,It should be adjusted as following:

  1. 电动或手动操作,将阀门关至“全关”位置后,切断电源。
  2. 松开开度指标盘上的指针螺钉,使指针与刻度盘上的“关”对齐,再将螺钉拧紧。
  3. 电动或手动将阀门“全开”,保持“关”指标盘不动,转动“开”指标盘至指针所在的位置。.

Operate the valve electrically or by hand wheel to “seated”position,then cut off power supply.Loosen screw of pointer on indicating dial,set pointer pointing to “CLOSE”,then fix screw ,Operate the valve electrically or by hand wheel to “complete opening”position,keeping the “closing dial”at original position,turn the “opening dial”to align with the pointer.

  1. 现场/远程操作 Local/remote operation
  2. 现场操作,需将现场/远控旋钮旋到现场位置,并用插的锁定。这时旋转开关旋钮(旋转的方向见旋转上的指示),即可进行现场开、关、停操作。每当阀位关到位,开度指示盘上的绿色指示灯亮。开到位,红色指示灯亮。运行过程中,按下开关旋转电装即停在中间位置。

For local operation,turn the local/remote knob to local control position and lock it with the latch.Then turn the operating knob(rotating direction as shown on knob)to carry out local operation of opening,closing or stopping.Once the valve is seated,the green lamp on position indicating dial lights;and the red lamp lights as the valve reaches preset position.During operation,once the knob is pressed down,the electric actuator stops at medium position.

  1. 远程控制,需将现场/远程旋钮旋到远控位置,并用插销锁定。整体式电动装置设有多种远控方式,可根据说明书中电气原理部分的控制方式进行选取。具体通过多功能控制模块(DGN-2)上三只拨码开关的不同组合来调整,并在接线盒中接远控控制线(根据不同控制模式,7~11号线端子上需接2~5根线),即可实现远程控制电动装置。如用户没有特殊要求,产品出厂时,远程控制方式为第二种带自保持的打开/停止/关闭控制方式。

For remote operation,turn the local/remote knob to remote control position and lock it with the latch.integrated model electric actuators are provided with many modes of remote control.Control mode can be selected according to electrical schematic diagram in this instruction manual and can be regulated particularly by different combinations of three unit selector switches on multi-function module(DGN-2).At the same time,wire remote control lines in the terminal box(2~5lines are needed for NO.7~NO.11 terminals according to different control modes).Thus,the electric actuators can be controlled remotely.If users have not put forward any special requirements,the remote control modes is set to second control mode of opening/closing/stopping with self-holding when the actuator is delivered.

  1. 阀位变送器的调整 Adjustment of transmitter

BS-1 阀位变送器其取样电位器选用高精度导电塑料电位器(独立线性度<1%,寿命10X106次)。图14中18、19为接线板端子号(即电流输出端)D1和D2为内部接线号,H为指示灯,其亮度随输出电流的增大而变亮。调整方法如下:(以输出轴顺时针转动为关阀为例)使阀门处于全关位置,关方向旋转取样电位器转轴,使输出电流从大到小接近4mA(导电塑料电位器无限位)调节T1微型电位器,直至输出电流精确为4mA;打开阀门至全开位置,调节T2,直至输出电流精确为20mA。如果输出轴逆时针转动为关阀,则红线和绿线需对调并电位器的调节旋向应相反。需要注意,阀门从全关到全开,取样电位器转角必须保证在150~270̊ 之间,否则需更换电动装置最大转圈数的规格。高精度导电塑料电位器的安装位置为替代图13中的普通电位器。
