为了正确的判断试验结果，有必要事先了解测试对象的液压系统和各液压执行部件，掌握必要的资料，比如：操作压力、流量、溢流阀设定压力、液压泵的最高输出压力、液压泵的性能曲线等。
①液压软管的连接检测仪如上表所示有三种机型，其软管的连接分两种类型a、PFM6-50、PFM6-85为1英寸的PT内螺纹。
b、PFM6-200上附有1英寸PT螺纹的连接器。
90°的管接头、T型管接头、阀等距离检测仪的输入端最好在30cm以上，因为这些部件将会给流体的测量带来误差。
软管的另一侧（与被测机器连接侧）通常与连接检测仪一侧为相同连接螺母，所以当管径或螺纹不同时，请利用转接器。
②操作要领检测仪的操作是简单的，但误操作将会给检测仪或被测试机器、回路带来不良影响。
使用者在使用前请读熟本使用说明书，避免误操作，以提高测试效率。
a、转换开关通常在中央位置（OFF）测试流量时请放在（FLOW）档位测试油温时请放在（TEMP）档位测试结束后，请勿必将开关拨回到OFF位置。
干电池使用过期电压下降时，仪表（流量、温度计上的冒号：）将发生闪烁。
此时，请更换干电池。
b、认真确认软管是否已正确无误地连接在检测仪的输入、输出端。
检测仪可以并列接入高压侧，但流向若是接反则不能测量正确的流量。
c、液压回路动作前，应将加载阀反时针方向旋转打开。
d、加载阀可以用手简单地进行操作，在加压和卸压时，请缓慢地进行操作。
e、液压回路动作停止之前，要将加载阀打开，确认压力是否已降到零。
在进行多项压力测试时，每一次测试结束，也都应该将加载阀先打开，然后进行下一个项目的测试。
f、安全圆片是保护检测仪和液压机器的，测试时，请密切注意压力表的读数，使之不要超过回路的最高压力。

Normal operation will be in the RUN mode . To access the program mode, press the MENU button until the first programming screen is displayed . After programming the display with the necessary information, a lock out feature can be turned on to prevent unauthorized access or changing the meter’s setup parameters .BASIC PROGRAMMING MODEKeys:MENU – Switch between RUN and PROGRAM modesUP Arrow – Scrolls through programming sub-menus in forwarddirection and increments numeric variablesRIGHT Arrow – Scrolls through programming sub-menus in reverse direction and moves the active digit to the rightENTER – Used to enter sub-menus, save programming informationand in the reset processIf your monitor was ordered with an Omega flow meter, the two compo-nents ship from the factory calibrated as a set . If the monitor is a replace-ment, the turbine’s K-factor has changed, or the monitor is being used with some other pulse generating device, programming will be necessary . PROGRAMMINGEach turbine flow meter is shipped with either a K-factor value or frequency data . If frequency data is provided, the data must be converted to a K-factor before programming . K-factor information, when supplied, can usually be found on the neck of the flow meter or stamped on the body . The K-factor represents the number of pulses per unit of volume . The K-factor will be needed to program the monitor .ENTER PRO GRAM MO DE – Change to program mode by press-ing the MENU button once . The mode indicator will change from RUN to PROGRAM .78ton once . The current meter size number will begin to flash . Using the arrow keys, scroll through the size choices until you find the bore size ofyour meter . Press ENTER once to save the meter size choice .Rate / Total DisplayAndProgrammingKeys Mode IndicatorAndProgramming ChoicesFigure 2: Flow Monitor ControlsENTER THE METER’S K-FACTOR UNIT – Directly after the METER size is selected, the display’s K-factor unit must be chosen . Use the UP arrow key to select your K-factor unit . For meters calibrated in gallons, use PUL/GAL (pulses per gallon); for meters calibrated in cubic meters, use PUL/M3 (pulses per cubic meter), etc . Press ENTER to save the K-factorunit and advance to the next parameter .SELECT THE RATE/TOTAL UNITS OF MEASURE – The monitor allows the choice of five common rate/total units . The monitor shows the rate/ total unit that the display is currently set for . If the current selection is correct, press the ENTER key once to advance to the next parameter .

At the 4mA OUT prompt, adjust the 4mA value to obtain a 4mA reading on the amme-ter . The UP arrow key increments the value and the RIGHT arrow key decrements the value . When a steady 4mA reading is obtained on the ammeter, press the ENTER key to lock in this value and move to the 20mA adjustment . The 20mA adjustment is performed using the same procedure as the 4mA adjustment .4-20mA TEST – The monitor contains a diagnostic routine that allows the simulation of mA values between 4 and 20 to check output track-ing . At the 4-20TEST prompt the arrow keys change the simulated mA output in increments of 1mA . The ammeter should track the simulated mA output . If a 4-20mA test in not necessary, pressing the ENTER key once will escape the testing at any time .1011Figure 3: Typical Ammeter ConnectionPASSWO RD – Password protection prevents unauthorized users fromchanging programming information . Initially, the password is set to all ze-ros . To change the password, simply enter any 4 digit code using the arrow keys as previously described to enter the password value . Pressing ENTER once will store the password and take you back to the RST PSWD screen .RST PSWD – The reset password screen allows the operator to enter any 4 digit code for the manual reset totals function .RESET TOTAL – To reset the monitor total display, in RUN mode press the MENU and ENTER simultaneously until TOTAL RST starts to flash . The TOTAL RST will stop flashing and the display will return to the RUN mode at the conclusion of the reset procedure .STORE TOTAL – The current total can be manually stored in the monitor’s flash memory . Press and hold the ENTER key for 2 seconds . The display will respond with a flashing TOTALSVD and then return to the RUN mode .AUTOMATIC STORE TOTAL – The monitor is equipped with a store total feature that works automatically, saving the current total to flash memory . The frequency of saves depends on the power supply option chosen .Loop Powered: Once every ten minutes . ADDITIONAL INPUT OPTIONSThe FTB–1400 Flow Monitor is capable of receiving magnetic pick-up input (small signal sine wave) or a contact closure input (pulse) . Since Omega FTB–1400 Flow Meters utilize a magnetic pick-up, the monitor is shipped configured for magnetic pick-up input . To change to a contact closure in-put, remove JP2 from the top two pins and jumper them to the bottom two pins .

Other features that make the PCL120 stand out include a “% error” function, which eliminates manual error calculation and allows the display of actual versus ideal error at any calibration point. The PCL120 can simulate, power, and measure 2-wire transmitters. Its’ automatic step and ramp functions enable remote calibration of 4 to 20 mA devices.The PCL120 has many innovative, powerful features that make calibration easy. A few clearly marked keys give the user access to the full functionality of the unit. The STEP and RAMP output modes automate either a discrete 4-8-12-16-20-16-12-8-4 mA stair step output or 2 speeds of a linear 4-20-4 mA ramp output. Pressing the AUTO key (1) activates this time-saving function. To further aid remote calibration, the PCL120 features a minimum/maximum value recall function. In the measure mode, holding the AUTO(/MAX) key (1) gives a direct readout of the maximum value, while holding the 25%(/MIN) key (4) gives a direct readout of the minimum value. Holding the % ERROR key (2) while turning the large knob provides instant feedback on the difference between the ideal and actual current values required for a given device response. This tells the user whether the device is within its accuracy range. No further calculations are necessary. A LOOP POWER key (3) provides instant 24 Vdc loop power output. The 25% (4) key provides instant outputs of 4, 8, 12, 16, and 20 mA loop current, with increments occurring each time the key is pushed.PCL120, shown smaller than actual size.OMEGACARE SM extended warranty program is available for models shown on this page.

伺服阀的使用
伺服阀的使用1、伺服阀的使用：设备选用的伺服阀均有自己的特点，在使用中需严格按照该种伺服阀的使用说明书要求进行操作。
一般来说，射流管式伺服阀要求用户不能拆卸伺服阀体，只能冲洗伺服阀的精密过滤器。
有些型号的伺服阀在用户处则可以进行整体拆洗，但拆卸的人员必须经过专业的技能培训才行。
伺服阀的装拆应在尽可能干净的环境中进行，拆装前对伺服液压系统停机，操作时应先取下连接到伺服阀上的电气信号插头，再卸掉伺服液压系统的剩余压力，然后拆下伺服阀。
在洁净的90、93、97号汽油中清洗所有的零件，对阀体一些清洁不到的地方，可以采用大号塑料外壳的医用注射器吸取汽油进行多次注射冲洗，零件清洗后可以晾干或用软气管以洁净、干燥的空气吹干。
（特别注意：不要采用玻璃管的注射器进行相关操作，因为玻璃管注射器在经过汽油的浸泡后容易碎裂，造成不安全的事故发生。
）清洗后的伺服阀，一定要放在洁净的环境中使其不要受到二次污染。
安装、拆卸冲洗板时也要与伺服阀一样，特别注意环境的洁净度，这样可以保障系统经过冲洗后的洁净度，才能保障伺服阀的耐用和控制的准确性。
伺服阀的精度等级较高，价格也较高，对其进行操作时需要特别小心细致，以防止在拆装过程中对其损坏。
伺服阀的过滤器、过滤芯可采用干净的90、93、97号汽油冲洗，对杂质和污染物多的过滤器滤芯也只能进行反复多次冲洗，不可对其采取火烧的办法来处理，假如采用火烧一些纤维状的物质碳化后会夹在过滤器中，容易使过滤器发生更进一步的堵塞，影响过滤器的使用，导致伺服阀的性能下降，严重时会导致伺服阀失效。
有一类过滤器是采用塑料材料制成的，假如采用火烧的办法，将使过滤器彻底报废。
⑶伺服阀使用的注意事项：①由于每种型号的伺服阀都有其额定的电压、液压等级；因此禁止伺服阀在超过额定电压、液压等级的条件下使用。
②禁止使用未经过滤的液压油，更不能使用其他不合格的液压油。
③禁止在伺服阀周围使用明火，同时也禁止其在高温状态下工作（使用环境要求见伺服阀说明书）。
电液比例伺服阀控实验台操作指导书
电液比例伺服阀控实验台操作指导书电液比例伺服阀控实验台主要用于完成伺服阀、比例阀的静特性实验和电液位置控制系统实验，也可以完成电液比例伺服系统的研究型实验。
阀控实验台主要组成元件见图1。
实验台需要与液压泵站和测控系统配合使用，具体操作如下：一、实验前准备1、启动前首先检查线路，确保测控计算机、测控箱、通电正常，正常后启动测控计算机、同时为测控箱上电。
2、检查电液比例伺服阀控实验台接线和泵源连接的软管接头是否漏油，确保无线路断裂、接头松动，无液压漏油、管路开裂等现象。
3、检查油源的压力油出口和回油口的闸阀是否打开，液压油箱的液位是否在规定范围内。
确认正常后，方可开机进行试验。
4 、启动油源电机，交替调节比例溢流阀和电磁溢流阀，使系统压力调定到所需值；如试验完毕或短时不用，交替调节比例溢流阀和电磁溢流阀，使压力下降到最低压力，系统处于卸荷状态。
二、实验台控制油路操作按油源操作步骤，启动泵源并调定好系统压力，将压力油进油闸阀根据所使用的阀搬至相应位置。
压力油进油闸阀有3个，分别控制进入试验比例阀、试验伺服阀和加载伺服阀的压力油，在做不同的试验项目时，打开相应的进油闸阀。
根据选定的实验项目，参考油路图确定正确操作方法，将相关闸阀搬至相应工作位置。
注意，闸阀中心的红一字线与闸阀长边中心线一致时为接通，垂直时为切断。
具体的操作如下：三、实验操作步骤3.1 流量特性实验流量特性实验是通过控制伺服阀或比例阀线圈电流的变化，测量阀的流量大小的变化情况。
得出电液伺服阀或比例阀的空载流量与阀的线圈电流之间的关系，流量-电流曲线为阀的流量特性曲线。
操作步骤：1）调节阀供油压为额定供油压力，切换实验油路——关闭QF3、4、5、7，打开QF6、8、9，将两个节流阀开口调至最大开口。
2）选择通过测试程序，选择伺服阀或比例阀的“流量特性”检测项目，测控箱选择“仪控”工作方式（具体操作见测控箱使用说明书）。
3）通过计算机程序和多功能测控箱产生频率为0.01Hz至0.05Hz幅值为额定电流的三角波信号加给伺服阀或比例阀（详细操作见测控软件说明书）。

Mechanical feedback (mfb) and pressure control valves are not catered for by the G040-123.穆格 G040-123型伺服阀监测仪是一种能对穆格阀就近能对阀的流量控制，比例阀和伺服阀电气信号反馈检测的仪器。
带机械反馈的压力控制阀不能用G040-123型检测仪。
The feature that makes it so versatile is the way it can test a valve while thevalve is still installed in its normal operating plant. This is done at two levels,“in line” and “stand alone”.这种仪器特点能对安装在阀台上正常工作的阀门进行多方面的检测和操作。
这里有两种测试方式：在线检测和独立检测。
Plant (In Line) 工厂工作（在线检测）As in fig a) the plant and valve operate normally. In fig b) the Valve Checker isconnected between the plant electronics and the valve such that all the plant electronics’ signals, to and from the valve, are connected as normal. The ValveChecker monitors the plant electronics’ signals and the signals back from thevalve, enabling a check of the valve’s performance.图a为电气线路与控制阀通常连接方式；图b为伺服阀检测仪串联在电气线路和控制阀总电气线路之间，保证阀输出输入线路在正常状态。
检测仪器能检测电气信号和输入给阀信号，来检测阀的性能。
Checker (Stand Alone) 检测模式（独立检测）In this mode the plant command is switched out while the Valve Checker generates the command to the valve and monitors the signals back from it. Thevalve remains installed in the plant but the plant command signals are disconnected. Checking while still installed in the plant provides the added benefit of checking the valve by observing the reaction of the plant to the ValveChecker’s commands.在这个模式下操作，工厂工作指令被断开，检测仪的控制信号输给阀，阀的反馈信号在回到检测仪。
尽管检测仪还串联在电路中，但工作的信号已经被断开。
检测的同时，可以由检测员给出指令来监测被测阀的动态变化。
The Valve Checker is powered by the plant electronics which also continue tosupply the valve in both plant and checker modes of operation. As well, there is a +24V DC power connector on the front panel for 24V DC and ± 15V DC powered valves, without connection to the plant electronics’ power.检测仪的供电源由原电路供给，同时能继续提供给被检测的阀在“工作”和“检测”模式操作提供电源。
同样这里的24V直流电源可以提供阀电子元件所需的24V直流电源或± 15V 直流电源。
无须外接其它的电器电源。
Two cables connect the Valve Checker to the plant electronics and valve. Each of the Valve Checker models is dedicated to a power supply voltage and connector type. It is necessary to select the model type that has the correct connector and supply voltage. The table below shows the model numbers and their supply/connector types.连接在检测仪的两条电气线一条接供给的电线，另一条接被检测阀的上。
不论检测仪那个模式下都是这样连接来提供电源电压和连接方式（接头一般类型一样），对于必须要选择类型的要纠正连接类型和提供的电源电压。
下表提供的是型号和电源电压参数Model dash number table:零件模块参数表Model dash 型号— connector 接头、插接件 supply 供给There are six functional blocks on the front panel.在面板上有六个的功能模块1. Q Command 电流指令 4. Control 控制2. Spool 滑阀 5. Enable 开启，允许3. Power 电源 6. Valve Connector 阀连接接口Q Command 电流指令This block is active only when checker mode is selected. The rotary pot adjuststhe Q command level.只有在选在“检测模式”下这部分模块才能投入使用，旋转钮是调整电流的大小量的。
The grey test point gives a 0 to 10V signal proportional to the actual voltage orcurrent being delivered to the valve. The rotary selector switch selects the signal type that is connected to the valve.这个灰色的测电位点提供0V~10V成比例的输出真是电信号，信号主动传递给被检测的阀件，旋转的扶手开关选着输给阀信号的类型The +/- switch connects the valve Q command signal to the non-inverting (+ve gives P A) and inverting (+ve gives P B) inputs.这个“+/-”开关是连接阀的Q指令开关，开关在“+”位置（阀给油P A）输入，在“-”位置（阀给油P B）输入。
Spool滑阀The spool position signal from the valve is always available at the green spooltest point and passed on to the plant electronics regardless of the mode of operation. The green spool test point gives a 0 to 10V signal proportional tothe spool signal from the valve. The LED display to the left of the test point provides a rudimentary indication of the signal. The centre blue null LED willbe illuminated when the spool signal is less than 10.不论哪种控制模式下，从阀来的阀芯位置信号总是在测试点上呈绿色，这些绿色测试点上的电信号与提供的0 ~ 10V电信号成正比例。
LED指示灯显示左边的测试点的迹象,提供了一个初步的信号，中心蓝色的LED零位指示灯在阀芯电信号小于10%时才亮。
An understanding of the checker load switch is important for successful use ofthe Checker, when the spool signal is a current (10mA or 4-20mA). When the valve has a current output there must be a path through which the current can flow, for the Checker to be able to measure the current. When the plant lectronics do no provide this load, or the Checker is not connected to the plant electronics, the Checker load switch connects a 100 Ohm load to ground (0V) on the spool signal, enabling a current to flow.检查员了解负荷开关,并成功运用的检查是很重要的。
