重庆川仪PDS压力变送器PDS说明书

重庆川仪PDS压力变送器PDS说明书
图8 引压口的位置
导压管应垂直或倾斜排布,即使水平排布,也应有适度的倾斜,使过程介质不会残留在管道内。
(2)变送器的位置
过程介质为液体或蒸汽时,原则上变送器的位置低于引压阀;
过程介质为气体时,原则上变送器的位置高于引压阀。
(3)冷凝、防冻
测量蒸汽介质时,导压管内的液体因过程温度或环境的变化而反复凝结、蒸发,会使高低侧分别产生液柱,液柱的高度不同将为测量带来误差,因此,蒸汽测量时请使用冷凝槽。
图9 压力变送器安装结构件
安装方式
变送器的水平配管(压力过程连接)安装采用条形安装板+U型螺栓+现场安装管的方式,安装管直径Φ50?Φ60mm,安装板与变送器用螺栓螺母连接,装配力矩。
图10 压力变送器安装
变送器的启用
压力过程回路
以下举例说明压力回路的连接,如图11。
图11 压力过程系统连接图
按如下步骤,检查压力回路通畅且无泄漏。
电子室旋转
变送器的电子室可顺时针或逆时针旋转,但为了电子室内的连接安全,旋转有一定的角度限制。如图4所示,壳体与测量部连接的颈部有两片阴影部分区域,测量部的颈部有“旋转定位标识”,壳体与测量部的相对旋转在“旋转定位标识”指向阴影部分之内均可,可旋转的总角度270°(旋转时,“旋转定位标识”不可经过非阴影区域)。具体方法为:松开外壳紧固螺钉,根据现场的安装要求旋转,完成后拧紧外壳紧固螺钉。
与电压>60V的线缆隔离;
避开附近大功率电气设备,使用屏蔽电缆(屏蔽层双端接地良好)。
接线腔连接
变送器采用二线制传输,因此信号线即电源线,与外部电源的连接示意图如图2。
图2 变送器与外部电源的连接示意图
变送器通过电缆与电源和负载构成回路,在图2中,使用屏蔽电缆,屏蔽层连接到接线端子的地端,该端已与变送器外壳相连,要求屏蔽层另一端与现场大地可靠连接,否则不能达到良好的屏蔽效果。

输送线-PDS说明书

PDS平面式输送机使用说明书重庆XX自动化设备有限公司地址:重庆市电话:移动电话:传真:邮编::400712一、概述PDS平面式输送机是由挠性输送带作为物料承载体和牵引体,由传动滚筒依靠磨擦力带动输送带送行的一种连续运输设备。

本机的机身侧板通常采用专用铝合金型材,结构简单,外型轻巧美观,使用安全可靠,安装、调试、维修方便,也可采用折板或矩管制作。

由于采用电磁调速电机驱动或变频调速驱动,故调速范围大,可达到1:10范围内无级调速,使用非常方便,广泛适用于轻工、电子、食品等行业中的流水作业和运输。

二、分类按输送机类型可分为:(1)橡胶带:根据客户要求可配普通、耐热、防油等橡胶带。

注:该类型结构还可用传动带,钢网带等替代橡胶带。

(2)进口PVC带:具有防静电、防油的功能。

PDS □·□—□输送带类型机架高度输送带宽度平面带式输送机例如:PDS400·700—I 表示带宽400mm,机架高700mm的橡胶带平面输送机。

三、主要技术参数四、主要结构和原理平面带式输送机由驱动装置,机身支架和运输带四个部分组成。

现场组合安装,见图一除上图所示的直线段线体外,还可根据用户要求设计,制造转角≤90°的任意角度的弯带。

如图二所示:1、驱动部分驱动部分见图三。

根据输送带的长度,负荷运行情况,配备相应的动力和减速系统。

由于皮带要运行速度要求较低,电动机直接传动显然达不到要求,为此通常采用三级调速方式,即电磁调速装置或变频调速装置调速,蜗轮蜗杆减速机减速,以及链轮匹配调配速度,使线体整体速比大,运行性能好,可在10倍范围内实现无级调速。

根据现场位置或客户要求,驱动部分可任意放置于线体中部或端部,张紧装置采用螺杆调节。

本机属中、小型设备,采用单滚筒驱动,滚筒面包防滑胶以增大摩擦力;对于长距离,大运量的情况,为增大牵引力可采用双滚筒或多滚筒驱动。

电气控制部分通常装在驱动部分的端部或侧面,必要时可设一电柜控制。

MODIS 二级图像产品技术说明书(版本号:V1.1)东海预报中心陈钊一、MODIS仪器、平台及其技术性能介绍简要介绍MODIS是Moderate-Resolution Imaging Spectroradiometer(中等分辨率光谱成像仪)的缩写。

该仪器是拥有36个可见光和红外通道的卫星遥感仪器,主要用于地球环境观察、搭载于美国国家航空航天局发射的EOS系列卫星上。

为了支持全世界科学界对地球环境的研究,EOS系列卫星通过X波段下行数据链路向全世界公开免费广播MODIS观测数据。

接近于MODIS的其它卫星遥感仪器有欧洲空间局EviSat卫星上的MERIS 仪器,我国在“神舟-3”飞船上实验的CMODIS,和“风云-3A”卫星上搭载的MERIS。

卫星平台搭载MODIS的目前有2颗卫星,EOS-AM,EOS-PMEOS-AM又名Terra,拉丁文意为大地,1999年12月18日发射升空,采用太阳同步轨道(SSO),设计为“上午星”,周期约100分钟,对于地球上同一地方每天可提供2次成像,星下点地方时约为昼间10时30分、夜间22时10分。

Terra卫星在轨道运行的艺术想象图EOS-PM又名Aqua,拉丁文意为“水”,2002年5月4日发射,轨道特性与Terra基本相同,但设计为“下午星”,星下点地方时约为昼间14时,夜间1时40分。

Aqua 卫星在测试厂房中照片(太阳能翼处于折叠状态)技术性能MODIS仪器的36个波段特性表如下:表1:反射性波段(RSB)表2热辐射性波段(TEB)上述各通道中,1、2通道的星下点空间分辨率为250米。

3、4、5、6、7通道的星下点空间分辨率为500米。

其余各个通道的星下点空间分辨率约为1千米。

二、东海预报中心的MODIS数据接收和处理2.1 数据接收东海预报中心通过星地通卫星数据广播接收站接收Terra、Aqua卫星的MODIS数据。

卫星数据广播接收站并不直接接收Terra、Aqua卫星的数据,卫星数据由中国气象局的大型地面站接收,可较好的保证接收数据的质量。

图8变送器与接头法兰连接图9变送器与三阀组连接
2.5.3 导压管的装配
(1)系统引压口
压力管道内的沉淀物、残液等进入导压管,将导致压力测量时产生误差。要排除这些影响,应按图10所示的角度范围安装引压阀。
过程介质为液体时,引压口水平或水平之下45°之内;
过程介质为气体时,引压口垂直向上或与垂直向上呈45°角之内;
过程介质为蒸汽时,引压口水平或水平之上45°之内。
图10引压口的位置
导压管应垂直或倾斜排布,即使水平排布,也应有适度的倾斜,使过程介质不会残留在管道内。

G ravity varies significantly with geographical location and this variation has a direct effect on the force of the weights and the accuracy of the Deadweight Tester. Each instrument can be calibrated to local gravity at no extra cost. If unspecified, instruments will be supplied calibrated to Standard Gravity 980.665 cm/s2.
Software is also available for:
• Piston effective area calibration
• Area and mass calculations • Differential Deadweight Testers
Technical Specification:
Program calculations include:
• Gravity
• Temperature • Air density • Actual weight mass • Head of fluid or gas • Density of fluid • Combined surface tension and fluid loading/buoyancy • Piston effective area • Piston distortion coefficient

足够;进行压力过程连接时,请确认相关阀门已关闭;连接完成 后,请确认连接部分介质密封性良好;在需要排气排液时,应采 取相应的安全措施,避免高压或腐蚀介质造成人身伤害及财产损 失。 2.5.1 变送器的测量部 变送器的测量部由膜盒、容室法兰、排气排液塞、螺栓螺母等零件组 成。变送器的安装、压力过程连接、现场压力的引入都在这一部分。
警告 对隔爆型变送器,上电时严禁拧开视镜盖旋转显示器。 2.3.5 接地 变送器上有内接地和外接地,两处均有接地标识,可任选其一或两处 接地,接地电阻≤100Ω。 2.3.6 电源电压与负载电阻
变送器的电源电压 U(单位 V)的范围:10.5≤U≤45 变送器回路的负载电阻 R(单位Ω)应满足公式 1 的要求。
变送器使用安装管加支架的安装方式,安装管直径要求Φ50ÆΦ60mm, 先将安装板用U型螺栓固定在安装管上,然后将变送器用四颗螺钉固定在安 装板上。如果操作不便,也可先连接变送器与安装板,再连接到安装管。 变送器的安装板可适应多种安装管的位置,但原则上,变送器安装完成后, 正负引压口应处于同一水平线上。
2.1.3 电磁环境条件 1) 磁场强度:≤400A/m 2) 射频干扰:≤3V/m(80MHzÆ1GHz) 3) 静电干扰: ≤8000V 4) 电快速瞬变脉冲群干扰:≤2000V(5kHz)
2.2 产品的验收 变送器安装使用前,请按订货合同验收,核对规格、型号、量程范围、
位号等信息是否正确;检查安装板、U 型螺栓、螺母、垫圈、说明书、合格 证等附件是否齐备。
压力管道内的沉淀物、残液等进入导压管,将导致压力测量时产生误 差。要排除这些影响,应按图 10 所示的角度范围安装引压阀。
过程介质为液体时,引压口水平或水平之下 45°之内; 过程介质为气体时,引压口垂直向上或与垂直向上呈 45°角之内; 过程介质为蒸汽时,引压口水平或水平之上 45°之内。

1.0 版
目录 1 前言
1.1 概述 1.2 标识说明 1.3 版本说明 1.4 品质保证
导压管应垂直或倾斜排布,即使水平排布,也应有适度的倾斜,使过 程介质不会残留在管道内。 (2) 变送器的位置
过程介质为液体或蒸汽时,原则上变送器的位置低于引压阀; 过程介质为气体时,原则上变送器的位置高于引压阀。 (3) 温差、冷凝、防冻、防风 配管时应尽量使两导压管不产生温差,因为温差会引起介质密度的变 化,导致测量误差。 测量蒸汽介质时,导压管内的液体因过程温度或环境的变化而反复凝 结、蒸发,会使高低侧分别产生液柱,液柱的高度不同将为测量带来误差, 因此,蒸汽测量时请使用冷凝槽。 应采取适当的措施,防止变送器及导压管内的过程流体发生冻结。凝 固的介质可能会损坏传压膜片。 用差压变送器测量微压时,低压侧应有稳定的参考压力。如果参考压 力为大气,需要保证无风,此时可将变送器置于箱内或将低压侧引入防风 盒内。 2.5.4 水平配管安装方式
图 5 电源负载图 2.4 通信连接
变送器的通信方式有 HART 和 PROFIBUS 两种,这里对 HART 型变送 器的通信连接作简要介绍。
HART 型变送器的输出在 4Æ20mA 信号的基础上调制了 HART 数字信 号。HART 信号以 2200Hz 表示“0”,以 1200Hz 表示“1”,数字信号直流 平均值为 0,对 4Æ20mA 回路不产生影响。
在图 2 所示变送器与外部电源连接示意图中,HART 终端设备可跨接
在变送器的“+”、“-”端,也可跨接在负载电阻的两端。变送器可与系统 中所有 HART 类仪表如执行器、阀门定位器等配合使用,系统中可同时存 在 16 台 HART 仪器,使用 HART 终端设备可分别对它们进行操作。图 5 表达了 HART 信号可使用的电源负载区域。 2.5 压力过程连接
