镁合金定量出料机电器说明书
镁合金定量出料机电器使用说明书一、主要规格及技术参数：1、交流输入电源：交流380V（三相4线制）额定功率：30.8KW额定电流：136A2、PLC：S7-200，AC/DC/继电器CPU224：14I/10O3、SSR：过零型：电压：<240V电流：250A，80A触发电流：>5mA开启电压：>4v二、工作原理：主要控制开关说明：SA1——总电源开关 QF1——加热器电源开关 SA4——温度显示开关 SA3——PLC电源开关整个电器控制系统主要由加热控制电路和气动阀控制电路组成。
1、加热控制部分由温控器（SDC15）和固态继电器（SSR）以及热电耦（K系列）组成。
温控器是日本三武公司的SDC15（SSR型）。
它具有PID温度调节，加热器断路报警输出，SSR驱动输出（V<24V,I<360mA）。
固态继电器采用杭州西子的过零型SSR。
触发电压3—32VDC，触发电流<50mA。
SDC15通过热电耦把加热丝的实际温度采样进来与事先设定的温度值比较后由事先设定PID值确定通过事件输出端口向SSR发出通或断的信号。
同时SDC15还设定了PV（现场温度值）低限报警值，一旦加热丝的温度低于此值就向PLC发出报警信号（PLC EM223 I1.6）。
PLC程序就会停止。
2、气动控制部分由传感器，电磁阀，PLC组成。
PLC采用西门子的S7-200，阀门位置传感器和液位传感器、旋转汽缸位置传感器共同组成反馈系统。
3、控制过程：在加热丝加热一段时间后，加热丝温度处于正常值，PLC上电，（此时坩锅内熔液已准备就绪），抽液/放液旋钮从中间位置拨到抽液位置，打开气路单向阀5YV（开始抽真空），真空泵抽管内空气同时二位五通气路换向阀1YV得电（抽液通道）打开，2YV失电（放液通道）断开，利用真空泵产生的负压将坩锅内熔液抽到定量筒中，当定量筒内镁液的液面到达指定位置S1（液面传感器）动作，此时立即关5YV（抽真空结束）关闭真空泵，同时1YV失电（抽液通道）关闭，2YV得电（放液通道）打开。

When replacing parts such as armature or drum, you will probably reuse the Poly V-belt once removed.In this case, remove the belt by turning V pulley 4-37in the direction of the arrow while lifting up the belt with a Lock nut wrench of a Makita grinder. (Fig. 1)When you replace the Poly V-belt with a brand-new one, remove simply by cutting the worn belt with cutting pliers.<2> Replacing Armature and Drum Disassembling1. Remove Chip cover, and then remove Brush holder caps carbon brushes.2. Remove six M4x25 Pan head screws fastening Bracket complete to Main frame complete as illustrated to left in Fig.3.3. Holding the handle, turn the tool so that it stands on Base. With plastic or wooden hammer, hit Main frame complete alternately at the two portions designated by the black arrow as illustrated to right in Fig. 3. The assembly of Bracket complete, Drum and Armature will then be removed from Main frame complete.4. Remove V pulleys from Bracket complete as described below;Hold Drum or Armature assembly with rags. And then using a wrench 13, remove V pulley 4-37 (right-handed) by turning it counterclockwise, and V pulley 4-20L (left-handed) by turning it clockwise.Assembling1. Remove Belt cover.2. Install Poly V-belt 4-241 securely on V pulley 4-20L, and then install the belt on V-pulley 4-37 while turning V pulley 4-37 in the direction of the arrow. (Fig. 2) Note : It will help you easily install Poly V-belt 4-241 to follow the instruction described below; In order not to allow the belt to be out of the V-grooves on the two V pulleys, while turning V pulley 4-37, press the half of the belt opposite to the other half being installed as illustrated in Fig. 2.Always follow the instructions of the SAFETY RULES and OPERATING INSTRUCTIONS described in the instruction manual. Also refer to the instruction manual for how to replace and adjust the planer blades.CAUTION: Before starting repair, be sure to unplug the tool and remove planer blades from the tool for safety.Fig. 1(continued to next page)[3] Planing Depth Adjustment<2> Replacing Armature and DrumDisassembling5. Remove Ball bearings 6000ZZ and 608ZZ from Drum using Bearing extractor (No.1R269).Between Drum and Ball bearing 608ZZ, there is no space for insertion of the jaw of the bearing extractor. When removing Ball bearing 608ZZ, therefore, be sure to use a proper adjustable wrench to securely hold the jaws of the bearing extractor so that the jaws cannot spread and slip off the ball bearing. (Fig. 4) Note : Be careful not to cut yourself on the sharp edges on the front faces of Drum.Scale label on knob 42 does not indicate correct planing depth after replacement of any one of the following parts:Front base, Base, Main frame complete, Knob 42In this case, be sure to replace Scale label and do planing depth adjustment as described below.1. Remove Scale label from Knob 42, and then assemble Base and parts of Front base section to the tool.2. Put the tool on a completely flat surface such as the table of stationary planers or the turn table of LS-series models. (If these tools are not available, use a stainless steel scale instead.)And then turn Knob 42 so that the height of Base is completely aligned with that of Front base.3. Install Scale label on Knob 42 so that the line of 0mm on Scale label is aligned with the apex of the triangle mark on Main frame complete as illustrated in Fig. 6.Fig. 6Assembling1. Do the reverse of disassembling procedure.2.
