迪普马DUPLOMATIC放大板EDM-M3111/30E0意大利迪普马DUPLOMATIC数字放大器用于开环比例阀EDM-M*系列EDM-M1单电磁铁EDM-M2双电磁铁EDM-M3两个单电磁铁独立通道导轨式安装形式:DINEN50022EDM-M*型卡是一种用于开环比例阀控制的数字放大器。其设计符合导轨式安装形式：DIN?EN50022。该单元提供和参考输入信号成比例的可变电流，不受温度变化或者负载阻抗的影响。电磁铁电源的PWM特性减小了阀的滞环，从而优化了控制精度。该单元可提供三种主要形式，可控制单电磁铁阀(M1)，双电磁铁阀(M2)和两个独立通道控制两个单电磁铁阀(M3)。每个形式均可根据相应的阀，优化定制各种不同的大电流规格和开关频率(PWM)。参数调节可通过前面板上的按键和显示完成，或者通过RS232或USB转换器(EDMPC/20软件)，连接笔记本电脑实现。功能说明电源放大板所需要的供电电源为10到30VDC之间(端子1和2)。注意：放大板的电源电压值必须高于所控制电磁铁的额定工作电压。电源电压必须经过整流和滤波，并且大允许波动在上述电压范围内。卡所需要的功率由电源电压值和供电电流大值决定(取决于卡的型号)。通常来说，所需功率的稳妥值可以认为是VxI的乘积。例如：卡的大电流=800mA且电源电压为24VDC，则所需要的功率约为20W。如果卡的大电流=1600mA并且电源电压为24VDC，则所使用的功率等于38.5W。电气保护放大板具有防止超压和极性反转的功能。输出端有短路保护。参考输入信号放大板可接受来自于外部发生器(PLC，CNC)，或者由卡本身供电的外部电位计，提供的电压参考输入信号0-10V和±10V，以及电流参考输入信号4-20mA。相应的参考输入值取决于卡的型号。信号供电指示(电源)两个红色的显示表示卡的电源：亮-电源正常不亮-无电源闪烁-其他放大板状态输出放大板的状态可通过位于针脚9(参考零电源，针脚15)的“卡状态输出"进行检测，带220K?负载阻抗，大电流100mA。若卡正常工作，此针脚处的电压和电源相同；如果卡出现故障，输出电压为零。故障包括：低电压(低于10V)短路未连接线圈如果针脚9的输出过低，控制逻辑会禁止电源输出供给电磁铁。如果故障解除，放大板将会自动重启。调节有两种调节模式：参数观测和参数编辑。一种模式可实时监测各控制值，包括两个通道中需要的和可读的电流值。二种模式可进行工作参数观测和编辑。参数观测放大板切换到参数观测模式时，显示的一个变化参数值为通道1的参考输入信号。通过按键()和(-)，可切换不同的参数。每选中一个参数时，它的名字缩写将会出现约一秒钟。通过短暂地按下按键(E)，当前参数名会显示约一秒钟。可选择的参数包括：U1:通道1参考输入信号:09,9V用于单电磁铁4-20mA；-9,9/0/9,9V用于双电磁铁4/12/20mAC1:根据输入信号，通道1所需要的电流，单位安培，范围从0到3.0A。E1:通道1实际提供的电流，单位安培，范围从0到3.0A。U2:通道2参考输入信号：09,9V用于单电磁铁4-20mA；-9,9/0/9,9V用于双电磁铁4/12/20mAC2:根据输入信号，通道1所需要的电流，单位安培，范围从0到3.0A。E2:通道2实际提供的电流，单位安培，范围从0到3.0A。所有提到的参数，均可从位于插头前面板的两位数字显示观测到。参数编辑按住键(-)1,5秒钟以上，可从参数观测模式切换到参数编辑模式，反之亦然。在参数编辑模式中，和前述模式一样，可通过短暂按下键()和(-)，切换不同的参数。每选中一个参数时，它的名字缩写将会出现约一秒钟。通过短暂地按下按键(E)，当前参数名会显示约一秒钟。按住键(E)1,5秒钟以上，参数名大约闪烁一秒钟：通过按键()和(-)，可修改参数值。每当这些按键中的一个被按下，相应值加大或者减小一个单位；按住按键不放，值可持续加大。一旦编辑获得所需要的值，通过按下按键(E)退出。此时，值存储在EEPROM中，按键()和(-)恢复其参数选择功能。一旦参数化循环完成，按住按键()2秒以上，直至显示开始闪烁，所有参数都将被存储到EEPROM中，并且重新回到参数观测模式。可选择的参数包括：G1:“IMax"电流，以毫安表示。此参数设定了参考输入信号为大值10V(或者20mA)时，供给通道1电磁铁的大电流。此参数用于限定阀控制的液压尺寸大值。o1:“IMin"电流，以毫安表示。此参数设定了参考输入信号超出0,1V(或者0,1mA)的限制时，通道1电磁铁的偏置电流。此参数用于清除阀的不灵敏区域(死区)。范围=IMax的0-50%r1：“MaxRamp"-斜坡时间，单位秒。当参考输入信号从零到100%变化时，该参数设定了通道1供给电流从零到大值所需的时间，反之亦然。此参数用于减慢阀的响应时间，以防输入信号出现突变。范围=00-20秒u1:“RampUp"上升斜坡时间，以斜坡时间r1的%进行表示。该参数设定了输入信号从0到100%变化时，通道1的电流加大时间。默认值=99%范围=00-99%d1:“RampDn"-下降斜坡时间，以斜坡时间r1的%进行表示。该参数设定了输入信号从100%到0变化时，通道1的电流减小时间。默认值=99%范围=00-99%G2:“IMax"-电流，以毫安表示。此参数设定了参考输入信号为大值时，供给通道2电磁铁的大电流。o2:“IMin"-电流，以毫安表示。此参数设定了通道2电磁铁的偏置电流。范围=IMax的0-50%r2:“MaxRamp"-斜坡时间，单位秒。当参考输入信号从零到100%变化时，该参数设定了通道2供给电流从零到大值所需的时间，反之亦然。此参数用于减慢阀的响应时间，以防输入信号出现突变。范围=00-20秒u2:“RampUp"上升斜坡时间，以斜坡时间r2的%进行表示。该参数设定了输入信号从0到100%变化时，通道2的电流加大时间。默认值=99%范围=00-99%d2:“RampDn"下降斜坡时间，以斜坡时间r2的%来进行表示。该参数设定了输入信号从100%到0变化时，通道2的电流减小时间。默认值=99%范围=00-99%Fr:“PWMFreq"-PWM，单位Hertz。此参数用于设定控制电流的脉动频率PWM。减小PWM能够提高阀的精度，但会降低调节稳定性。加大PWM能够提高调节稳定性，但会加大滞环。默认值=PWM(根据卡的型号)范围=50-400HzU1和U2:此参数表示设的量程范围。通过此参数(仅可通过软件进行修改)，即使设低于10V，仍可保持同样的分辨率。例如：卡EDM-M121，带10V指令且参数标准设定，输出电流范围1200mA。如果“U"的设定值为500，输出电流范围为600mA。如果卡被设定用于单电磁铁阀，只有通道1的参数可以观测到。安装此卡为导轨式安装设计，符合DINEN?50022形式。接线通过端子板完成，位于电子控制单元的底部。推荐截面积0.75mm2，长度至20m的电缆和截面积1.00mm2，长度至40m的电缆，用于电源和电磁铁连接。对于其他连接，推荐使用带屏蔽护套的电缆，且仅卡侧接地。意大利迪普马DUPLOMATIC放大板订货型号：EDM-M112/40E0-BEDM-M212/30E1-BEDM-M231/30E0-BEDM-M31111/30E0-AEDM-M31111/40E0-AEDM-M31111/30E0-BEDM-M31122/30E0-BEDM-M32222/40E1-BEDM-M212/30E0-BEDM-M212/30E1-BEDM-M222/40E0-BEDM-M231/31E0-BEDM-M111/40E0-BEDM-M112/40E1-BEDM-M212/40E0-BEDM-M212/40E1-BEDM-M231/40E0-B迪普马DUPLOMATIC放大板EDM-M3111/30E0放大器EDM-M231/30E0-B电磁阀DS3-SA2F/13N-D24K1F压力开关PST4/21N-K1/K换向阀DSC3-SA1/11V压力开关PSP4/21N-K1/K节流阀RS2/30电磁阀DS5-S4/12N-D24K1单向阀MVPP-D/50节流阀MERS-D/50节流阀MERS-RD/50电磁阀DS5-S20/12N-D24K1迪普马放大板EDM-M3111/30E0电磁换向阀DS3KD2-S4/10V-R240K9T02/CM迪普马DUPLOMATIC电磁阀DS3-TA/11N-D24K1迪普马DUPLOMATIC电磁阀DS3-S3/11N-D24K1压力继电器PST6/21N-K1/K电磁阀MDS3-SA1/10N-D24K1迪普马DUPLOMATIC电磁阀DS3-S1/11N-D24K1迪普马DUPLOMATIC电磁阀DS3-TB/11N-D24K1迪普马DUPLOMATIC电磁阀DS3-S2/11N-D24K1三联齿轮泵GP3F-0394R97F/20NGP1M-0061RF/20NGP1M-0041RF/20N10通径电磁阀线圈C31-D24K1/20迪普马DUPLOMATIC电磁阀DS5-S3/12N-D24K1单向阀MVPP-SA/50伺服阀DXJ5-DOL100/10N/E0K11电磁阀DS5-S1/12N-A230K1电磁换向阀DXJ3-DOL20/10N/EOK11直流220V电磁阀线圈C31-D220K1/22压力传感器PTH-250/20EO-K10升级型号PTH-250/30N-E0K10电磁换向阀DS5-S2/12N-D24K1液压阀RQ3-P5/41流量阀RPC1-16/CT/41压力开关PSP6/21N-K1/K电磁换向阀DS3-S4/11N-D24K1插装溢流阀CR5/22N插装式溢流阀CR6/22N齿轮泵GP3-0264R97F/20N放大板EDM-M212/30E0-B齿轮泵GP30337R97F20N压力传感器PTH-250/20EO-K10升级型号PTH-250/30V-E0K10电磁换向阀MD1D-TA/50220V停产用新型号DS3-TA/11N-A230K1替代溢流阀RQM3-P6/A/60NAC230V放大板EDM-M212/30E1-B插装阀VR5-I1/32放大板EDC-131/10E1液压阀RM3-W6/30N液压阀RS4/20升级为RS4/30压力传感器PTH-250/30V-E0K10电液换向阀E07E-S92/1/5124升级DSPE7-A150/31N-II/D24K1电磁阀线圈C22S3-D24K1/11溢流阀RQ7-P6/41三联齿轮泵GP2F-0113R97F/20NGP1R-0020RF/20NH比例阀DSE5-A60/10N-D24K1电磁换向阀DS5-S2/12N-A230K1电磁阀DS3-S3/11N-D28K1用DS3-S3/11N-SD28K1电磁阀DS3-TB02/11N-D28K1用DS3-TB02/11N-SD28K1电磁阀DS3-TA23/11N-D28K1用DS3-TA23/11N-SD28K1比例阀PRE10-350/20N-D24K1液压泵DFP2-14RA1/20N压力继电器PSP6/21N-K1/K电磁换向阀DS3-SA23/11N-D24K1比例伺服阀DXJ5-DOL100/10N/E1K11比例溢流阀RQE3-P5/53-24NL用PRE10-210/10N-D24K1替代单向阀VD4-W1/30气动换向阀DSA3-S1/11N电磁阀MDS3-S1/10N-D24K1先导式溢流阀RQ3-P6/41电磁换向阀DS3-23TA/11N-D24K1比例溢流阀PRE10-350/10V-D24K1单向阀CHM5-SB/10N电磁阀DS3-S10/11V-SD24K7/W7电磁阀DS3-S1/11V-SD24K7/W7比例伺服阀DXJ5-D0L100/10N/E0K11插装式单向阀VR2-I1/32单向阀CHM5-SA/10N比例溢流阀RQE3-P5/53-

迪普马DUPLOMATIC节流阀MERS-RD/50对节流阀的性能要求是：·流量调节范围大，流量一压差变化平滑；·内泄漏量小，若有外泄漏油口，外泄漏量也要小；·调节力矩小，动作灵敏。节流阀(Chokevalve)的外形结构与截止阀并无区别，只是它们启闭件的形状有所不同。节流阀的启闭件大多为圆锥流线型，通过它改变通道截面积而达到调节流量和压力。节流阀供在压力降较大的情况下作降低介质压力之用。介质在节流阀瓣和阀座之间流速很大，以致使这些零件表面很快损坏，即所谓气蚀现象。为了尽量减少气蚀影响，阀瓣采用耐气蚀材料（合金钢制造）并制成顶尖角为140～180的流线型圆锥体，这还能使阀瓣能有较大的开启高度，一般不推荐在小缝隙下节流。节流阀按通道方式可分为直通式和角式两种；按启闭件的形状分，有针形、沟形和窗形三种。可调节节流阀：阀针和阀芯采用硬质合金制造，产品按API6A标准设计，具有耐磨、耐冲刷性能。主要用于井口采油（气）树设备。滑套式节流阀：阀芯采用低噪音平衡型结构，开启轻便，产品按API6A标准设计，阀芯表面覆盖碳化钨，适合于有闪蒸、高压差，高压力，空化等条件苛刻的场合，使用寿命长，流量调节精度大大提高。适用于石油，天然气，化工，炼油，水电等行业。迪普马DUPLOMATIC节流阀MERS-RD/50意大利迪普马DUPLOMATIC节流阀叠加式ISO4401-07(CETOP07)工作压力350bar流量250l/min该阀是一种叠加式流量控制阀，集成单向阀允许油液反向自由流动。其安装面尺寸符合ISO4401（CETOPRP12H）标准。该阀可通过螺栓或螺钉与其它符合ISO4401-07（CETOP07）标准的阀组合成叠加阀组，无需油管连接。通常供货时带沉头内六角调整螺钉以及锁紧螺母。逆时针旋转，流量增加。结构“SA"：控制由执行机构流入管路A的流量。“D"：分别控制执行机构两腔的排出流量。各型号阀均集成单向阀，允许油液反向自由流动（开启压力0,7bar）。技术参数（在油温50°C，油液粘度36cSt条件下测得）MERS-RD/50MERS-D/50MERS-SA/50MERS-SB/50迪普马DUPLOMATIC节流阀MERS-RD/50放大器EDM-M231/30E0-B电磁阀DS3-SA2F/13N-D24K1F压力开关PST4/21N-K1/K换向阀DSC3-SA1/11V压力开关PSP4/21N-K1/K节流阀RS2/30电磁阀DS5-S4/12N-D24K1单向阀MVPP-D/50节流阀MERS-D/50节流阀MERS-RD/50电磁阀DS5-S20/12N-D24K1迪普马放大板EDM-M3111/30E0电磁换向阀DS3KD2-S4/10V-R240K9T02/CM迪普马DUPLOMATIC电磁阀DS3-TA/11N-D24K1迪普马DUPLOMATIC电磁阀DS3-S3/11N-D24K1压力继电器PST6/21N-K1/K电磁阀MDS3-SA1/10N-D24K1迪普马DUPLOMATIC电磁阀DS3-S1/11N-D24K1迪普马DUPLOMATIC电磁阀DS3-TB/11N-D24K1迪普马DUPLOMATIC电磁阀DS3-S2/11N-D24K1三联齿轮泵GP3F-0394R97F/20NGP1M-0061RF/20NGP1M-0041RF/20N10通径电磁阀线圈C31-D24K1/20迪普马DUPLOMATIC电磁阀DS5-S3/12N-D24K1单向阀MVPP-SA/50伺服阀DXJ5-DOL100/10N/E0K11电磁阀DS5-S1/12N-A230K1电磁换向阀DXJ3-DOL20/10N/EOK11直流220V电磁阀线圈C31-D220K1/22压力传感器PTH-250/20EO-K10升级型号PTH-250/30N-E0K10电磁换向阀DS5-S2/12N-D24K1液压阀RQ3-P5/41流量阀RPC1-16/CT/41压力开关PSP6/21N-K1/K电磁换向阀DS3-S4/11N-D24K1插装溢流阀CR5/22N插装式溢流阀CR6/22N齿轮泵GP3-0264R97F/20N放大板EDM-M212/30E0-B齿轮泵GP30337R97F20N压力传感器PTH-250/20EO-K10升级型号PTH-250/30V-E0K10电磁换向阀MD1D-TA/50220V停产用新型号DS3-TA/11N-A230K1替代溢流阀RQM3-P6/A/60NAC230V放大板EDM-M212/30E1-B插装阀VR5-I1/32放大板EDC-131/10E1液压阀RM3-W6/30N液压阀RS4/20升级为RS4/30压力传感器PTH-250/30V-E0K10电液换向阀E07E-S92/1/5124升级DSPE7-A150/31N-II/D24K1电磁阀线圈C22S3-D24K1/11溢流阀RQ7-P6/41三联齿轮泵GP2F-0113R97F/20NGP1R-0020RF/20NH比例阀DSE5-A60/10N-D24K1电磁换向阀DS5-S2/12N-A230K1电磁阀DS3-S3/11N-D28K1用DS3-S3/11N-SD28K1电磁阀DS3-TB02/11N-D28K1用DS3-TB02/11N-SD28K1电磁阀DS3-TA23/11N-D28K1用DS3-TA23/11N-SD28K1比例阀PRE10-350/20N-D24K1液压泵DFP2-14RA1/20N压力继电器PSP6/21N-K1/K电磁换向阀DS3-SA23/11N-D24K1比例伺服阀DXJ5-DOL100/10N/E1K11比例溢流阀RQE3-P5/53-24NL用PRE10-210/10N-D24K1替代单向阀VD4-W1/30气动换向阀DSA3-S1/11N电磁阀MDS3-S1/10N-D24K1先导式溢流阀RQ3-P6/41电磁换向阀DS3-23TA/11N-D24K1比例溢流阀PRE10-350/10V-D24K1单向阀CHM5-SB/10N电磁阀DS3-S10/11V-SD24K7/W7电磁阀DS3-S1/11V-SD24K7/W7比例伺服阀DXJ5-D0L100/10N/E0K11插装式单向阀VR2-I1/32单向阀CHM5-SA/10N比例溢流阀RQE3-P5/53-24NL停产建议用PRE10-210/20N-D24K1替代电磁阀DS3-S3/11N-A110K1电磁阀DS3-S1/11N-A110K1电磁阀DS3-TA/11N-A110K1伺服阀DXJ5-D0L060/10N/E0K11插头放大板UEIK-11/51-24电磁方向阀座DT03-3C/10/24CC电磁阀DS5-S3/12N-A110K1压力继电器PSP2/21N-K1/K充液阀CFP-S040/0/10C电磁阀DS3-S3/10N-D24K1/CM电磁阀DS3-RK/11N-D24K1电磁阀DSA3-TA/11N溢流阀MRQ4-SP/51用MRQ6-SP/51电磁阀DS3-TA23/11N-SD24K1放大板EDM-M231/20E0升级为EDM-M231/30E0-B电磁阀DS3-TA23/11N-SD24K电磁阀底座DSO7-S1/10N-IE配电磁阀DS3-S3/11N-D24K1溢流阀RQ3-P5/M/41比例阀DXJ5-D0L100/10N/E1K11电磁阀DS5-SA2/12N-D24K1比例阀DSE3-A26/11N-D24K1线圈C22S3-SD24K1/12溢流阀RQ7-P6/M/41电磁阀3WE6A62/EG24N9K4用DS3-23TA/11N-D24K1电磁阀3WE6B62/EG24N9K4用DS3-23TB/11N-D24K1电磁阀DSH3-SK1-11V\24VDC溢流阀RQM3-P5/A/M/60N-D24K1溢流阀RQM3-P5/A/60N-A230K1节能模块ECL/20数字放大器EDC-135/10E0溢流阀RQM3-P6/A/60N-A230K1电磁阀DS3-TA/11N-A230K1电磁阀DS5-S9/14N-D24K1/F/CM电磁阀DS5-TA/12N-D24K1/CM电液换向阀DSP7-S1/20N-EI/D24K1/CM电磁溢流阀RQM5-P6/A/60N-D24K1/CM电磁溢流阀RQM3-P6/A/60N-D24K1/CM电磁阀DS3-TA/11N-D24K1/CM液压阀ZC2-P4/51用ZC2-P5/51替代电磁溢流阀RQM3-P5/A/60N-D24K1液压元件DS3-S3/11N-A230K1液压元件RQ4M6-SP/51液压阀MCD5-SAT/51液压阀MZE5/58-24电磁阀DS3-RSA4/11N-A230K1液压元件C22S3-D220K1/12调节阀DT03-3C/10-220RAC配件RP1-12配件RP3-100电磁溢流阀RQM7-P6/A/60N-D24K1/CM节流阀QTM7-D/10N/S电磁阀DS3-S2/11N-D24WK1/CH/W7/A215用DS3-S2/11N-D24K1/CH/W7液压阀ZC2-P4/51液压阀DS3-SA3/11N-D24K1液压阀DS3-S3/11N-SD24K1液压阀DS3-RSB2/11N-D24K1液压阀MCD6-SP/51N电磁阀DS3-S4/11N-A110K1减压阀MZD3/RP/50插头MPM电磁阀灰色插头液压阀RQM5-P5/A/60N-D24K1双联泵GP3F-0337R97B/20N＋GP2R-0113RB/20N阀DS3KD2-S1/10N-D24K9T02/CM插头MPM电磁阀黑色插头液压元件DS5-S10/12N-D24K1溢流阀RQ3-P5/M/41电磁阀DS3-SA2/11N-D00电磁阀DS3-RK/11N-D00单向阀MZD3/50电磁换向阀DS3-RSB1/11N-D24K1单向阀MERS-SA/50电磁换向阀DS3-SA12/11N-D24K1单向阀MZD5/50放大板EDM-M111/30E0-B电磁阀DS3-S2/11N-D24K1节流阀QTM5-D/10N/S放大板EDM-M212/20E0升级EDM-M212/40E0-B电磁阀DS3-SA2/11N-D24K1电磁阀DS3-TB/11N-D220K1手动阀RPC-3T3/43手动阀RPC-2T3/31油缸HC2D-80/45-90-KO-0-11/20液压元件RQM3-P6/G/60N-D24K7/W7电磁阀MCD5-SP/51N溢流阀RQM5-P6/D/M/60N-D24K1放大板EDM-M212/40E1-B密封包SK/HC2-160/90-K/20(油缸型号HC2F-160/90-2350-KO-S-11/2/20)电液换向阀阀座（单独阀座）CE07HP4-S3/1/14升级为DS07H-S3/10N-II液压元件RPC1-4/CT/43电磁阀DS3-S9/11N-D24K1流量控制阀RPC1-16/CT/43流量阀RPC1-16/CT/41升级为RPC1-16/CT/43液压阀DSH3L-S1/10N放大器EDM-M112/30E1-B升级为EDM-M112/40E1-B放大板EDM-M212/30E1-B升级为EDM-M212/40E1-B单向阀MRQA-5/1/C/42液压阀MRQ5-SP/M1液压阀DS07-S2/10N-1E升级型号DS07-S2/10N-EE溢流阀CRQ6/12电磁阀DS3-SA1/11N-A24K1电磁阀DS3-S4/11N-SD24K1线圈C22S3-SD24K1液压元件DS5-TB/12N-D24K1液压元件SP40-060R88B/10N-ME100放大器EDC-131/10E0流量阀RPC1-4/CT/42单向阀RM45-MP/30升级为RM4-210MP/40N溢流阀PRE3-350/20V-D24K1溢流阀RQAM5-P5/1/A/51N-D24K1液压阀K

回阀旋启式止回阀安装位置不受限制，通常安装于水平管路，但也可以安装于垂直管路或倾斜管路上。注意事项安装止回阀时，应特别注意介质流动方向，应使介质正常流动方向与阀体上指示的箭头方向相一致，否则就会截断介质的正常流动。底阀应安装在水泵吸水管路的底端。止回阀关闭时，会在管路中产生水锤压力，严重时会导致阀门、管路或设备的损坏，尤其对于大口管路或高压管路，故应引起止回阀选用者的高度注意。止回阀只供防止各类管路或设备上流体介质逆流的单向启闭阀。
