DCS操作员站布置在机组控制台上,打印机布置在控制室内打印机台上。DCS工程师站布置在控制室内设置的工程师站室内。
译文:After automatic monitoring through MACS system, 2X60MW
Assembling Thermal-control Terminal Control Systematic
Engineering can fulfill all the monitoring functions
such as starting the whole sets of assembly, interlock
protecting, regular monitoring and emergent shutdown
through CRT and tracking ball / keyboard with less important
conventional monitoring instruments. It also can meet
the requirements under various kinds of operating modes
in the control room of the assembly. In the console
cabinet, control panel and platform are decorated separately;
operator's station of DCS is decorated on the assembly’s
control platform; the printer is fixed up on printer
platform and engineer station of DCS is assigned in
the engineer room.
采用MACS分散控制系统(DCS)实现:
a. 数据采集和处理系统(DAS)
b. 模拟量控制系统(MCS)
c. 顺序控制系统(SCS)等控制功能。

1.1.1 PISTON ROD
The cylinder piston rod is made of carbon steel and
is provided with a surface coating to improve the running
characteristics and to prevent corrosion. The type of
surface finish applied to the rod determines to a great
extent the corrosion resistance of the piston rod.
In determining the diameter, a number of aspects are
taken into account in the design. These aspects are:
· The resistance to bending, based on the design force
and on any transverse forces or frictional moments from
spherical bearings
· Stresses occurring as a result of the applied pressure
and tensile force
· Geometric requirements relating to the mounting of
the piston and the attachment to the driven construction

1.1. 1活塞杆
该汽缸活塞杆由碳钢制成,外着一层防护涂层,以增强其运转性能并使其具有防腐功能。此种表面防护层的应用,使得活塞杆具有相当的耐腐蚀性。
要确定活塞杆的直径,设计时要考虑如下因素:
· 抗弯曲,基于球形的轴承引起的,设计力以及任何横向力或者摩擦力矩。
· 由于外加电压和张力引起的压力。
· 有关活塞安装及驱动结构的附件的螺旋状要求。
操作简便
所有控制、检测、监视和保护信号均送到现地PLC,并可通过人机操作面板
(触摸屏)和计算机监控系统进行监控。液压系统和电控系统中所有元器件
标识清楚,部分元器件还带有灯光指示,操作一目了然。
易于维护
液压系统所有控制阀件均集中安装于阀块上,检修和更换方便。
液压系统和电控系统所有元件均具有通用性、互换性,更换方便。
液压系统管路上设有手动隔离阀,方便检修。
译文:Convenient operation
All the signals of control, measure, monitoring and
protecting are sent to PLC filed, and can be monitored
through the touch-sensitive screen and computer monitoring
system. All components and parts in the hydraulic pressure
and electric control systems are identified clearly,
even some of them with light instruction, which makes
operation is very convenient.
Easy Maintenance
All control valves in the hydraulic pressure system
are installed on the collectively. It is apt to safeguard
to control the valve one to install on the valve block,
which makes maintenance and renewal conveniently.
All components in hydraulic pressure and electric- control
system have common-ability and interchangeability. It
makes the replacement easily.
Manual isolated valve on the pipeline of hydraulic pressure
system makes the maintenance convenient.
