开利流量开关的工作原理

开利流量开关的工作原理

开利流量开关的工作原理
开利流量开关是一种用于控制液体或气体流动的装置。

它的工作原理主要基于液体或气体的流动压力和流速。

开利流量开关内部通常有一个弹簧,一个可变阻尼器和一个浮子。

弹簧用于保持流量开关的状态,使其在正常工作时处于关闭状态。

可变阻尼器用于根据流体流速调节浮子的位移,从而控制开关的状态。

当流体流动通过流量开关时,流体的流速会引起浮子随之移动,浮子的位移会改变浮子上附加的磁棒和磁场传感器之间的相对位置。

当浮子移动到某个特定位置时,磁棒会接触到磁场传感器,从而改变磁场传感器的状态。

磁场传感器的状态变化会被传输给控制器,控制器根据接收到的信号决定是否打开或关闭流量开关。

当流速超过预设值时,浮子位移将足够大以使磁棒接触到磁场传感器,此时控制器将开启流量开关。

相反,当流速低于预设值时,浮子的位移将不足以使磁棒接触到磁场传感器,此时控制器将关闭流量开关。

综上所述,开利流量开关的工作原理主要是通过测量流体流速,根据测量结果控制浮子位移并改变磁棒与磁场传感器之间的相对位置,从而实现开关的打开和关闭。

流量开关原理

流量开关原理

流量开关原理
流量开关是一种用于控制液体或气体流动的装置。

其原理基于一个阀门机制,通过开启或关闭阀门,来控制流体的通道的开闭。

流量开关通常由两部分组成:传感器和控制单元。

传感器负责检测流量,并将这个信号传送给控制单元。

控制单元根据传感器的信号,决定是否开启或关闭阀门,以控制流体的流动。

当流量开关的传感器检测到流体流动时,它会发送一个信号给控制单元,控制单元会根据预设的参数来决定阀门的开闭情况。

如果流量达到或超过了预设的值,控制单元将关闭阀门以限制流动。

反之,如果流量低于预设值,控制单元将打开阀门以允许流动。

流量开关可以应用于各种场景,例如工业生产中的液体管道控制、自动化系统中的流量控制等。

通过使用流量开关,可以提高流体管道的安全性和效率,同时实现自动化控制。

流量开关调整注意事项 流量开关是如何工作的

流量开关调整注意事项 流量开关是如何工作的

流量开关调整注意事项流量开关是如何工作的流量开关是利用各种原理测量管路中介质的流动情况并实时地传输给后端设备已开关通断信号的一种传感掌控器。

流量开关依据原理的不同分为机械形式和电子形式,机械形式的流量开关紧要是依靠给管道加添阻力的方式来获得动力,来推动相关的开关元件,进而实现检测过程。

流量开关调整注意事项:1、流量开关出厂调整在最小流量值相近,在使用时不得调到低于出厂设定位置,否则会造成开关不能回复到“无液流”位置。

2、若需调高流量值,应顺时钟旋转调整螺丝。

在调高出厂设定值后想调低流量值,可逆时钟旋转调整螺丝。

3、调整结束后,应检查流量开关的设定值不低于出厂设定值,通过按动主杠杆数次,检查主杠杆回复时开关有无“咔嗒”声,一旦发觉没有,应顺时钟旋转调整螺丝直至杠杆回复时有“咔嗒”声。

4、封漆的设定螺丝不可调整。

一旦变动,将会破坏流量开关的掌控或造成调整失效而无法工作。

5、流量调整过高,低流量时无法带动流向片,开关无法动作。

流量调整过低,开关过于灵敏,产生误动作机械形式的流量开关与感应式流量开关的优势对比:机械形式的流量开关:价格低,管道压力损失大,开关点重复性差,过载本领差(变形后不易恢复)等。

感应形式的流量开关:价格高,管道压力损失可疏忽,开关点重复性好,过载本领强等流量开关紧要是在水、气、油等介质管路中在线或者插入式安装监控水系统中水流量的大小。

在水流量高于或者低于某一个设定点时候触发输出报警信号传递给机组,系统取得信号后即可作出相应的指示动作。

避开或削减主机"干烧"。

流量开关工作原理:水流量开关工作原理当水流开关内有水流动,水流量≥1.0L/min时,水流开关内的磁芯受水流推动产生位移,磁芯位移带动磁源产生磁控作用使水流开关输出"通"信号。

流量开关快易优自动化选型有收录,该信号输入设备掌控系统,经掌控系统实现掌控作用,当水流量小于启动流量时,水流开关输出"断"的信号。

流量开关 工作原理

流量开关 工作原理

流量开关工作原理
流量开关是一种控制网络数据流量传输的设备。

它的工作原理是通过监测和调控网络传输中的数据流量,实现对数据流量的开关功能。

具体来说,流量开关通过对网络流量进行分析和筛选,将符合特定规则的数据流量传输放行或阻断。

流量开关通常由硬件设备和软件控制系统组成。

硬件设备负责实现物理层面的数据接口和连接,其中包括网络接口、数据线路等。

软件控制系统则是实现流量管理、数据处理和控制的核心部分。

软件系统通过对网络流量的数据包进行解析和分析,根据预设的策略和规则进行判断,并决定是否放行或阻断相应的数据流量。

流量开关的工作原理可以简单概括为以下几个步骤:
1. 监测网络流量:流量开关通过网络接口或者镜像端口监听网络数据的流动情况,实时获取数据流量信息。

2. 数据包解析:将监听到的数据流量转化为数据包进行解析处理,包括解析数据包的头部信息、IP地址、协议类型、端口号等。

3. 流量分析和识别:流量开关根据预设的规则和策略,对解析得到的数据包进行分析和识别,判断是否符合设定的规则,如是否属于允许通行的流量。

4. 流量控制:根据分析和识别的结果,流量开关决定是否放行
或阻断相应的数据流量。

如果符合规则,则允许数据流量继续传输;如果不符合规则,则阻止数据流量的传输。

通过以上步骤,流量开关可以对网络数据流量进行有效的监控和控制。

它可以帮助网络管理员实现对网络的管理和保护,确保网络传输的安全、稳定和高效。

同时,流量开关还可以提供网络流量的统计和分析功能,为网络优化和故障排查提供支持。

IMF流量开关45127使用说明书

IMF流量开关45127使用说明书

IMF流量开关45127使用说明书
IMF流量开关45127使用说明书:
1、流量开关出厂调节在最小流量值附近,在使用时不得调到低于出厂设定位置,否则会造成开关不能回复到“无液流”位置。

2、若需调高流量值,应顺时钟旋转调节螺丝。

在调高出厂设定值后想调低流量值,可逆时钟旋转调节螺丝。

3、封漆的设定螺丝不可调节。

一旦变动,将会破坏流量开关的控制或造成调节失效而无法工作。

4、调节结束后,应检查流量开关的设定值不低于出厂设定值,通过按动主杠杆数次,检查主杠杆回复时开关有无“咔嗒”声,一旦发现没有,应顺时钟旋转调节螺丝直至杠杆回复时有“咔嗒”声。

5、流量调节过高,低流量时无法带动流向片,开关无法动作。

流量调节过低,开关过于灵敏,产生误动作。

泉州日新流量仪器仪表有限公司一、概述SLK智能流量开关,是采用应变靶式流量计的计量工作原理,为液晶背光显示界面,具备人机可视操作,用户使用一目了然。

并配以微型继电器输出控制的开关量信号,可直接驱动额定功率5A以下的负载(如电磁阀、气动阀、二次控制电器等),能准确地完成用户对瞬时流量的上限、下限控制,即可实现现场自动化控制。

二、工作原理SLK智能流量开关的工作原理基于应变靶式流量计的测量原理,其结合先进的传感器及微型计算机技术,当流体对靶板产生作用力后,应变传感器输出电压信号,此信号经放大后与设定值的对应电压作比较,若此信号等于或大于(小于)设定值,则继电器动作输出开关量的信号,同时发光二极管指示信号,通过继电器开关的通断来改变工作状态。

其设定值有上限、下限两个,可事先在出厂前根据用户要求设好,也可以在现场设定,其可调范围为4%~100%满量程,通常出厂值设为25%~75%满量程。

三、技术指标1、显示方式:液晶背光显示瞬时流量及其参数;2、控制方式:在仪表的量程范围内,可任意设定上、下限控制值;3、工作电压:24VDC4、工作压力:≤2.5MPa(25bar),高于2.5MPa(25bar)属特殊订货;5、工作环境温度:-30℃~80℃6、量程范围:1:10,高于10倍量程属特殊订货;7、输出信号:开关量(独立的两路通道:常开、常闭各一路);8、输出负载功率:≤5A,高于5A,属特殊订货9、控制精度等级:≥2%FS。

高于2%的精度属特殊订货;10、重复性:0.03%11、适应工况流量范围:详见仪表外壳铭牌;12、仪表显示单位:体积单位以m3(立方米)、L(升);质量单位以t(吨)、kg(公斤)。

仪表出厂以用户订单要求显示的单位为准,如需变更显示单位必须重新标定校准方可使用。

四、按键功能说明在仪表显示面板的下方设置有“系数”、“置零”、“切换”、“功能”的按键。

各按键功能不同但相互关联,用于控制仪表参数的设置及操作。

1. “系数”键:用于仪表系统各参数设定的界面切换。

2. “置零”键:用于流量传感器零点值的数据刷新。

3. “切换”键:用于读取流量传感器零点值。

4. “功能”键:用于瞬时流量、流量动态零点值的切换;用于对可写数据的置数或移位。

当仪表处于“系数”、“切换”、“功能”键操作任意界面时,此时互按其他键直接进入对应界面,仪表参数中的代号字符和运行结果的数据,是不可写的。

以下内容涉及“第一、二、三……位”的解释时,均定义为:自右向左一一对应。

五、操作界面功能仪表显示主界面为图1,该界面为当前瞬时流量值界面。

图1(当前瞬时流量值界面)图中F为当前瞬时流量值的代号,后四位示值为当前瞬时累积流量数值(流体没有流动时,则该值为0)1. “功能”键操作界面功能说明a. 当前流量动态零点值当在图1状态下,按“功能”键不放时,显示如图2的界面图2(读取当前流量动态零点值界面)该参数用于判断流量传感器性能状态参数。

当流体为常温(4℃~70℃)状态,且管道中流体处于静止状态,该值的波动变化应小于50个值。

流体为非常温或流动状态下,该值为动态变化,属正常现象。

在图2状态下松开“功能”键时,则直接返回主界面图12、“切换”键操作界面功能说明传感器零点值显示及刷新当在图1状态下,按“切换”键时,则进入图3界面(但当仪表处于其它按键操作状态下,按下“切换”键时,则直接跳跃进入图3的界面)图3(读取当前零点值界面)图中前两位EL为流量传感器零点值的代号,后五位为参数数据(即传感器静态零点值)。

该参数值可读写数据(但不能按位置数),在此界面状态下,每按一次“置零”键,则刷新一次当前仪表流量传感器零点值;零点值刷新操作详见调整校准零点值:指仪表安装(“安装”定义是指仪表校准时,也可以是用户正式安装后,或者是用户使用过程的校准)在管道流体上后,并且管道流体处于静止状态下,对上述置零(除皮)操作后的值,称为零点值。

仪表处于不同位置及不同环境状态,该值有所差异。

只要对初始状态进行清零后,即可正常工作。

再次按“切换”键,则回到图1界面。

特别提示:1、在流体流动的工作状态下,处于该界面不得刷新当前零点值。

2、属高温工作下的流体,应在高温状态下刷新零点值。

但流体必须处于静止状态下。

3. “置零”键操作界面功能说明该按键是配合应用的功能按键。

用于配合流量传感器静态零点值刷新(详见零点值刷新)。

泉州日新流量仪器仪表有限公司4.“系数”键操作界面功能说明a. 上限流量报警值设定当在图1状态下,按“系数”键时,则进入图4界面(但当仪表处于其它按键操作状态下,按下“系数”键时,则直接跳跃进入图4的界面)图4(上限流量报警值设定界面)图中前两位AH为上限报警值的代号,后四位为报警设定值,该数据可读写。

当瞬时流量大于该设定值时,面板上的L1、L2发出报警指示,并且控制继电器AL1、AL2输出开关量信号(显示指示和输出开关量信号状态的设置方式详见图7)。

修改参数:进入此界面第四位处于不停的闪烁,点按“功能”键置数(0~9循环),长按“功能”键右移到下一位,再点按“功能”键置数,如此操作输入需要设定的数据。

当在第一位长按功能键则再次移到第四位,实现重写操作(以下内容涉及参数修改的置数或移位均可按此操作,下不详述)。

输入所需的数据后按“系数”键,系统自动保存数据,且进入图5界面。

b. 下限流量报警值设定当在图4状态下,按“系数”键时,则进入图5界面图5(下限流量报警值设定界面)图中前两位AL为下限流量报警值的代号,后四位为报警设定值,该数据可读写。

当瞬时流量小于所设定值时,仪表面板上的L1、L2发出报警指示,并且控制继电器AL1、AL2输出开关量信号(显示指示和输出开关量信号状态的设置方式详见图7)。

参数修改设置参见图5操作方法。

再次按动“系数”键,则进入图6界面。

c. 报警回差值设定当在图5状态下,按“系数”键时,则进入图6界面图6(报警回差值设定界面)图中前两位HC为报警回差值的代号,后四位为报警回差值,该数据可读写。

该值为上、下限报警值的回差值(即公差带),如图4上限设定为5.500;图5下限设定为1.500;图6报警回差设为0.100。

即实际上限控制范围为:5.5+0.1=5.6时输出开关量信号;解除输出信号为5.5-0.1=5.4时输出开关信号即被解除。

实际下限控制范围为1.5-0.1=1.4时输出开关量信号;解除输出信号为:1.5+0.1=1.6时输出开关量信号即被参数修改设置参见图4操作方法。

再次按“系数”键,则进入图7界面。

d. 报警开关量输出状态设定当在图6状态下,按“系数”键时,则进入图7界面图7(报警开关量输出状态设置界面图中前两位AS为报警输出值的代号,后两位为设定值,该数据为可读写数据。

其中第二位(十位)为控制AL2继电器。

第一位(个位)为控制AL1继电器。

其中:0代表无开关量输出;1代表上限流量报警开关量信号输出:2为下限流量报警开关量信号输出。

用户可根据工艺需要设定对应的输出方式。

参数修改设置参见图4操作方法。

再次按“系数”键,则进入图8界面。

e. 小信号切除设定当在图7状态下,按“系数”键时,则进入图8界面图8(微落小信号切除值设定界面)图中前位cU为小信号值的代号,后四位小信号设定值,该数据为可读写数据。

其用于因工况流体静止状态下,使流量传感器零点飘移而造成的微小虚拟流量,取值大小设定方法详见“零点值校准方法”。

参数修改设置参见图4操作方法。

再次按“系数”键,则进入图9界面。

特特别提示:进入下一步界面之后的参数为仪表系统参数,不是仪表专业工程技术人员,请不要修改参数值,修改参数会直接影响仪表功能及工艺,造成的后果厂商概不负责。

f. 流量系数设定当在图8状态下,按“系数”键时,则进入图9界面图9(流出系数设定界面)图中前位cL为流出系数值的代号,后五位为设定值,该数据为可读写数据。

该数据为标定校准时设定,一般情况下,不得修改调整该数据,除非重新对仪表进行标定校准,方可修改数据。

校准修改方法详见“流出系数调整”。

参数修改设置参见图4操作方法。

再次按“系数”键,则进入图10界面。

g. 流量输出信号方式、显示单位、流量范围分级设定当在图9状态下,按“系数”键时,则进入图10界面。

图10(报警输出信号方式、显示单位、流量范围分级设定界面)图中前位n为分级和方式的代号,后位三位00系数数据为可读写数据。

后三位数据说明:第一位(个)数为流量范围分级:0为最大显示9.999(m3、L、t、kg 下同);1为99.99;2为999.9;3为9999。

该设置用于瞬时流量最大流量示值的分辨率。

该参数出厂设定后,用户不可修改调整。

第二位(十)数为显示单位的切换:30代表:m(立方米);1代表t(吨);2代表L(升);3代表kg(公斤)。

第三位(百)位数为AL1和AL2继电器输出信号方式控制:0代表:当上、下限报警时,继电器吸合,即连续输出开关量信号(持续时间直到当前流量解除报警,出厂默认设置为连续输出信号);1代表:当上、下限报警时,继电器断续吸合,即开关量信号断续输出(每间断3秒输出一次,直到当前流量解除报警)。

参数修改设置参见图4操作方法。

再次按“系数”键,则进入图1界面六、安装要求a. 建议仪表采用水平安装,如有特殊要求,垂直安装也可。

尽量保证前后直管段,即前≥10D;后≥5D(D为管道通径),如图11。

建议加旁通管,便于特殊情况下维护。

图11b. 对流量极小的流量,为防止因介质中杂质颗粒过大而堵塞,建议用户在仪表前端加装相应的过滤器等装置。

七、现场调整校准1. 零点值刷新仪表经检定出厂均经过清零,由于运输过程中不可避免的猛烈碰撞及安装后的误差,仪表有可能产生零点漂移。

为保证仪表的精确度,仪表安装完毕后,应进行零点值刷新(除皮)处理,刷新操作方法:a.首先使管道中充满流体(仪表应用在高温状态下,应在最高温度状态下),并保持流体处于静止状态,将仪表下游(如图11后管径阀门)阀门关闭;b.确认无流体通过条件下,按“切换”键进入图3界面,再点按“置零”键数次,待EL示值产生变动后,即完成零点值刷新操作,再按“切换”键退回主界面图1;c.对应用在高温流体中的仪表,安装到位后,使其运行一定时间,即仪表过渡件温度升至平衡点(不再升温)--SLK智能流量开关--d.然后再点按“切换”键退出,返回主界面图1,即完成安装后的零点值刷新(除皮)。

2. 流出系数调整仪表出厂时已进行标定校准,安装后不需修改此参数。

但仪表使用一段时间以后,不可避免的会产生一定的误差或周期校准时,可按以下两种方式校准:a.实流校准可按以下步骤进行:Ⅰ.分别记录下标准值和仪表当前平均瞬时流量示值。

Ⅱ.将所记录标准值和仪表当前示值分别代入以下公式:C新=C旧•Q标准Q当前(1)其中:C新——仪表待输入新流出系数。
