将卡住处放松  阀支管脏  由服务部维修  来自强振动连续受力的磨损产生电路板或阀支管之间的接点上有沉积物  用乙醇清洗接点表面 表 3 故障描述 原 因 正确做法  执行机构不移动  压缩空气 140kPa  调整进口压缩 空气 140kPa  压电阀不切换(虽然在用手动方式按压+、 键时可听到柔软的咔哒声)  限流器关闭(螺钉已转到右端停止)  打开限流器螺钉(见散页,用装置 6 概况)转向左端  阀支管脏  由服务部修理  一个压电阀经常在固定的自动方式(固定设定点)和手动方式  定位器,执 行机构气路系统泄漏, 在RUN3 开始检验(初始化)。  整修执行机构和气源管漏点  如果执行机构和气源管未受损,请与服务部联系维修或更换新的部件  阀支管脏(见上述)  同上 表 4 故障描述 原 因 正确做法  在自动方式下,两个压电阀在一个固定位置(设定点)经常交替切换(振荡)  配件填料盒上的静态摩擦力或执行机构的摩擦力太高  减少静态摩擦或定位器的死区(参数dEbA),振荡停止  执行机构,定位器,配件的安装  直行程执行机构: 检查耦合轮、螺钉的安装 角行程执行机构: 检查杆在定位器轴上的安装  校 正执行器与配件间的其它安装  执行机构动作速度太快  调整限流器螺钉增加定位时间  如需要快的定位时间,则应增加死区直到振荡停止  定位器不能驱动阀门升到最终位 置 供气压力低  调节器负载太低或 增加供气压力  改变介质负载 ( 20mA时) 系统输出太低,需要提供增大负载  选择 3/4 线制操作 表 5 故障描述 原 因 正确做法  零点偶然漂移  通过碰撞和冲击发生这样高的加速度,摩擦加紧单元位移。  断掉这种情况  定位器重新初始化  由服务部维修  装置功能全部断掉  不适应的电源  检查供电 经过振动有非常高的连续压 力,会发生:  电气端子螺钉脱落  电气端子 /电气模块被振动脱落  拧紧螺钉  由服务部处理 阀门定位器的简明操作指南 准备 1) 按照操作说明将定位器与阀门连接 2) 检查并确认电路和气路连接 3) 通电( 4~20mA电流供电) 禁止电压供电 初始化 1) 确认反馈角度( 330 和 900) 2) 利用调节轮和反馈杠杆调整定位器零点和行程(调节轮调整相当零点调整,反馈杠杆长度调整相当于行程调整) 3) 将行程下限调整至 5%~10% 4) 将行程上限调整至 90%~95% 5) 确认并保持阀门为中间位置( 50%) 6) 进入参数设置并且确认相关参 数(参数 3) 7) 进入参数 4,开始自动初始化(如手动初始化,则进入参数 5) 8) 初始化 9) 几个重要参数 1. YFCT(执行机关类型): Turn 角行程, way 直行程 2. YAGL(反馈角) 3. YWAY(行程值) 4. INITA(自动初始化) 5. ININM(手动初始化) 6. SCUR(输入电流范围) 7. SDIR(正反作用) 39. YCLS(阀门紧密关闭) 55. PRST(工厂设置) 附录一 SIPART PS2 6DR5xxxxx 散页“操作 简要说明” 1) 如果选择了“ turn”,不能设置 33 176。 2) 如果选择了 1. YFCT=turn,仅出现参数。 3) 如果选择 =FrEE,添加设置点出现。 4) NC 意味 : 执行机构开关打开或低位, NO 意味 : 执行机构开关关闭或高位。 5) Normal(常规 )意味:高位没有故障, Inverted(反常规 )意味 :低位没有故障。 附录二 部件安装图 模块盖 基本电子单元 固定螺钉 具有带状电缆的 Jy 模块( 6) 具有带状电缆的报警模块( 5) SIA模块 特殊螺钉 滑动夹紧装置的调节轮 变送比率选择器 隔离盖板 图 7 基本部件的 电路连接 图 8 非防爆而限制连接 图 9 防爆二线制连接 图 10 非防爆二线制连接 图 11 非防爆 3/4 线制连接 图 12 防爆二线制连接 图 13 防爆 3/4 线制连接 可选件的电气连接 图 14 非防爆 Jy 模块 图 15 防爆 Jy 模块 图 16 非防爆报警模块 图 17 防爆报警模块 图 18 非防爆 SIA模块 图 19 防爆 SIA模块 气动连接 NAMUR 标准反馈杠杆 1) 3~35mm 2) 5~130mm 图 20 连接尺寸图 图 21 外壳连接尺寸图 压力表模块连接尺寸 图 22 压力表模块连接尺寸 (英文版 ) easily blame, to prevent the broken window effect. Supervise the leading cadres to play an exemplary role, take the lead in the strict implementation of the code and rule , lead to safeguard the solemnity and authority of the party discipline, ensure that the party discipline and the laws and regulations for implementation in place. Throughout the discipline in the daily supervision and management , strengthen supervision and inspection, from the thorough investigation of violations of discipline behavior. Strengthen to key areas, key departments and key projects as well as the masses reflect the concentration of the units and departments for supervision. strengthening supervision, discipline inspection and supervision of cadres to set an example for pliance with the code and rule is a man must be hexyl, blacksmith needs its own hardware. Discipline inspection ans as the executor of the party discipline, and supervisor of the defenders, for its supervision must be more strictly, discipline inspection and supervision of cadres to firmly establish the awareness of Party Constitution, sense of discipline and rules consciousness, politics loyalty, sense obey. Action speak Ji Ordinance to set an example of the regulations of the rule of law, strengthen supervision and accept the supervision of the firmness and consciousness, do ply with and . To firmly establish the discipline must first be disciplined, the supervisor will be subject to the supervision of concept, and consciously safeguard and implement party passes party, take the lead in practicing three strict real strict, so loyal, clean, play. To be good at learning, the Constitution and the code as morality, politics and brought to fruition。 to implement , do not want to, dare not, not with disciplinary ruler to supervision。 to discipline a ruler, often the control inspection, and consciously in the ideological red line to draw the row Ming Good accumulation is indeed the bottom line, so that the heart has fear, said to have quit, the line has ended. Attached: indifferent to heart, calmly to the table in our life, there are many unpredictable things will happen, some good, some bad things, we cannot control is powerless to stop, but with time, you will find in life sometimes turns out to be not good, some bad things finally turned out to be a good thing, but then we muddy however did not know, this is the life teach us things. 1, life can be plex, can also be simple. Want simple life of precipitation, to have enough time to reflect, to make Bee more perfect. Life is the most important thing is not to win, but the struggle。 not to have conquered, but to have fought well. 2, the plain is the background of life. Live a plain life, give up on themselves is not a coward, but the wise answers。 not disillusioned after the heart, such as ashes, but experience the storm after the enlightenment。 not unrewarding perfunctorily, but calm attitude of life of unrestrained selfconfidence. Plain living, there is no noise noisy, no earthly troubles, more did not fill in the discontent of desire, some just a calm, a calm. 3, memory of heart will not good things to erase the, life is a When no movie, pain is a beginning, the struggle is a kind of process, death is a kind of ending. Give up this giving up is the helple。
