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.
Adopt the MACS decentralized control system(DCS)
a. Data Acquisition & Process System (DAS)
b. Analog Control System (MCS)
c. Sequential Control System(SCS) and other control functions
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
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.
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.
