注意
1 配管不能是螺旋状。
真空侧和供给侧都不能出现螺旋状配管, 应尽量短而直。 配管容积增 大则响应时间变长。
2 真空发生器排气侧的配管有效截面积应大。
排气一旦节流,真空发生器的性能就变差。
4 吸入流量过大,则真空开关的设定困难。
几 mm大小的小工件, 一旦选定吸入流量过大的真空发生器, 和未吸 着时的真空压力之差太小, 会使真空压力开关的设定变困难, 故要选 定合适的真空发生器。
注意
1 方向控制阀,速度控制阀等相关元件应参见各自样本的注意 事项。
维护
警告
1 要定期对真空过滤器和消声器进行清洗。
过滤器及消声器的孔眼被堵, 真空发生器的性能便降低。 在粉尘多的 场合,应使用处理流量大的真空过滤器。

SMC系列产品使用说明书

SMC系列产品使用说明书
拆卸时应先将电动装置吊装可靠再松开紧固螺栓,而后将其自阀门上取下。
5.4 SMC/HBC、SMC/JA部分回转产品的安装与拆卸方法是:
先将花键接头装到阀杆上,使电动装置二级减速机构的驱动轴位置与阀门所处位置相同。
(此时阀门在某一终端位置最理想)起吊电动装置,使其驱动轴与阀杆上的花键接头对准,同时应对准阀门与电动装置的连接螺孔。使驱动轴与花键接头配合装入,而后用螺栓将阀门与电动装置紧固可靠。
a、型号:该产品型号。
b、最大控制转矩:该产品出厂前调定的最大转矩值(N.m)。
c、输出转速:该产品在单位时间内输出轴的转圈数(r/min)。
d、最大转圈数:该产品位置指示机构指针从0~100%走满刻度情况下输出轴总的转圈数。
e、编号:该产品总序号或本年度产品的序号。
f、合同号:该产品年度订货合同号。根据它可查出产品出厂前的全部情况,便于售后服务。
与G·L·SW的触点信号不同,MDPI的阀位反馈信号是连续的。
(图19)所示为MDPI位置指示机构的结构。从图中可见其传动部分是若干对小模数配换齿轮,该机构对任何口径的阀门均能保证其指针做满刻度指示。
▼关于电动装置的控制器
对于一般控制原理,控制器是与电动装置分离的电气控制部件,它通常设置在控制室内为单独订货产品。
5.7电动装置的工作位置一般无原则要求。但推荐电动机轴线为水平状态,G·L·SW箱罩处于水平或垂直向上、向下状态,以利于产品的润滑、维修及阀位观测。
6.润滑
6.1产品出厂前已注入专用润滑脂,使用中每年应至少检查润滑情况一次,如无异常可继续使用。
6.2电动机轴承的润滑脂一般不必更换或添加。
6.3产品维修后更换润滑脂时应注意其抗氧化性、耐水性、耐热性、防锈性、机械稳定性等,并应注意其抗挤压性,以保证产品的润滑性能和较高的传动效率。

Then insert the body with (a) intothe panel until (a) comes into contact with the panel front surface. Next, mountpart (b) to the body from the rear and insert it until (b) comes into contact with thepanel for fixing.WiringWiring connectionsConnections should be made with the power supply turned off.Use a separate route for the product wiring and any power or high voltage wiring.Otherwise, malfunction may result due to noise.If a commercially available switching power supply is used, be sure to ground theframe ground (FG) terminal. If the switching power supply is connected for use,switching noise will be superimposed and it will not be able to meet the productspecifications. In that case, insert a noise filter such as a line noise filter/ferritebetween the switching power supplies or change the switching power supply tothe series power supply.How to use connectorConnector attachment/detachmentWhen connecting the connector, insert itstraight onto the pins, holding the lever andconnector body, and lock the connector bypushing the lever hook into the concavegroove on the housing.To detach the connector, remove the hookfrom the groove by pressing the leverdownward, and pull the connector straightout.DC(+)Pin No.OUT1OUT2FUNCDC(-)BrownBlackWhiteGrayBluePipingTightening the connection threadFor connecting to the body (piping specification: -M5)After hand tightening, apply a spanner of the correct size tothe spanner flats of the piping body, and tighten with a 1/6 to1/4 rotation.As a reference, the tightening torque is 1 to 1.5 Nm.(When replacing the piping adapter ZS-46-N∗, tighten it usingthe same method.)Piping specification: -01, -N01After hand tightening, hold the hexagonal spanner flats of thepressure port with a spanner, and tighten with 2 to 3 rotations.As a reference, the tightening torque is 3 to 5 Nm.When tightening, do not hold the pressure switch body with aspanner.Default settingsWhen the pressure exceeds the setvalue, the switch will be turned on.When the pressure falls below theset value by the amount ofhysteresis or more, the switch willbe turned off.

1 产品名称:SMC 缓冲器RB0604
缓冲器在不同的领域有不同的含义:在计算机领域,缓冲器指的是缓冲寄存器,它分输入缓冲器和输出缓冲器两种。

前者的作用是将外设送来的数据暂时存放,以便处理器将它取走;后者的作用是用来暂时存放处理器送往外设的数据。

有了数控缓冲器,就可以使高速工作的CPU 与慢速工作的外设起协调和缓冲作用,实现数据传送的同步。

由于缓冲器接在数据总线上,故必须具有三态输出功能。

在其他领域,还有电梯缓冲器,汽车弹簧缓冲器等,其目的是用于减缓速度,提高安全性和舒适性。
